Abstract:
<span>Multiprotocol Label Switching (MPLS) is a promising packet switching technology in the field of communication network, allowing router to forward the packets based on labels. However, off-the-shelves routers are made to be non-configurable, making it less suitable for academic research purposes. The aim of this paper is to explore the possibility of developing a configurable MPLS router by reviewing embedded system-based router, software-based router and commercial MPLS router itself. The architecture of the routers will be described in detail and their performances will be compared. From the analysis, we found that the development of reconfigurable MPLS router testbed is achievable by using embedded system-based hardware due to its freedom of reconfigurability.</span>

Abstract:
Smart Router is a router device that is equipped with Smart Wi-Fi software that allows us to easily manage and monitor the home network, and has more features or services than regular routers in general. Routers of this type include one solution in building a local area network that can be used as file server in file sharing. But regardless of the benefits it does not rule out the possibility of a crime by utilizing file sharing. Therefore, in the field of digital forensics required live forensic methods and live acquisitions, since the smart router belongs to a critical electronic item category, where data (log) can be lost when the device is turned off.

Abstract:
Router very important for computer network. To get the router can buy a router products but can also design your own using personal computers. Mikrotik is one of the router manufacturer that provides products in the form of hardware or software. If you want to pay less to design a router can use operating system Ubuntu. This operating system is open source and provided free of charge by the manufacturer. If you want to design a router with this OS can make use of personal computers are often used in homes or offices. Merging the performance of both types of routers can also be usedto cover the lack of one another. With the proxy on a local network then the use of bandwidth can be saved. Becausethere are several websites cached and stored therein if the same website is accessed by other users, the router transmits only from the proxy to the computerwhich make the request.

Abstract:
Internet routers have packet buffers which reduce packet loss during times of congestion. Sizing the router buffer correctly is important: if a router buffer is too small, it can cause high packet loss and link under-utilization. If a buffer is too large, packets may have to wait an unnecessarily long time in the buffer during congested periods, often up to hundreds of milliseconds. While an operator can reduce the operational size of a router buffer, the maximum size of a router buffer is decided by the router manufacturer, and the operator typically configures the router to use all the available buffers. Without clear guidance about how big a buffer needs to be, manufacturers tend to oversize buffers and operators tend to configure larger buffers than necessary, leading to increased cost and delay.

Abstract:
Virtualization has the advantages of strong scalability and high fidelity in host node emulation. It can effectively meet the requirements of network emulation, including large scale, high fidelity, and flexible construction. However, for router emulation, virtual routers built with virtualization and routing software use Linux Traffic Control to emulate bandwidth, delay, and packet loss rates, which results in serious distortions in congestion scenarios. Motivated by this deficiency, we propose a novel router emulation method that consists of virtualization plane, routing plane, and a traffic control method. We designed and implemented our traffic control module in multi-scale virtualization, including the kernel space of a KVM-based virtual router and the user space of a Docker-based virtual router. Experiments show not only that the proposed method achieves high-fidelity router emulation, but also that its performance is consistent with that of a physical router in congestion scenarios. These findings provide good support for network research into congestion scenarios on virtualization-based emulation platforms.

Abstract:
Virtualization is becoming more and more popular since the hardware that is available today often has theability to run more than just a single machine. The hardware is too powerful in relation to the requirementsof the software that is supposed to run on the hardware, making it inefficient to run too little software ontoo powerful of machines. With virtualization, the ability exists to run a lot of different software on thesame hardware, thereby increasing the efficiency of hardware usage.Virtualization doesn't stop at just virtualizing operating systems or commodity software, but can also beused to virtualize networking components. These networking components include everything from routersto switches and are possible to set up on any kind of virtulized system.When discussing virtualization of networking components, the experssion “Software Defined Networking”is hard to miss. Software Defined Networking is a definition that contains all of these virtualized networkingcomponents and is the expression that should be used when researching further into this subject. There'san increasing interest in these virtualized networking components now in relation to just a few years ago.This is due to company networking becoming much more complex now in relation to the complexity thatcould be found in a network a few years back. More services need to be up inside of the network and a lotof people believe that Software Defined Networking can help in this regard.This thesis aim is to try to find out what kind of differences there are between multiple different softwarerouters. Finding out things like, which one of the routers that offer the highest network speed for the leastamount of hardware cost, are the kind of things that this thesis will be focused on. It will also look at somedifferent aspects of performance that the routers offer in relation to one another in order to try toestablish if there exists any kind of “best” router in multiple different areas.The idea is to build up a virtualized network that somewhat relates to how a normal network looks insmaller companies today. This network will then be used for different types of testing while having thesoftware based router placed in the middle and having it take care of routing between different local virtualnetworks. All of the routers will be placed on the same server and their configuration will be very basicwhile also making sure that each of the routers get access to the same amount of hardware.After initial testing, all routers that perform bad will be opted out for additional testing. This is done tomake sure that there's no unnecessary testing done on routers that seem to not be able to keep up withthe other ones. The results from these tests will be compared to the results of a hardware router with thesame kind of tests used with it in the middle in relation to the tests the software routers had to go through.The results from the testing were fairly surprising, only having one single router being eliminated early onas the remaining ones continued to “battle” one another with more tests. These tests were compared tothe results of a hardware router and the results here were also quite surprising with a much betterperformance in many different areas from the software routers perspective.

Abstract:
The unprecedented growth of the Internet has brought about such an enormous impact on our daily life that it is regarded as indispensable in modern era. At the same time, the underlying Internet architecture is still underpinned by principles designed several decades ago. Although IP networking has been proven very successful, it has been considered as the cause to network ossification creating barriers to entry for new network innovations. To support new demands and requirements of the current and the future Internet, solutions for new and improved Internet architectures should be sought. Software-defined networking (SDN), a new modularized network architecture that separates the control plane from the data plane, has emerged as a promising candidate for the future Internet. SDN can be described as flow-based networking, which provides finer granularity while maintaining backward compatibility with traditional IP networking. In this work, our goal is to investigate how to incorporate flow-based networking into open router platforms in an SDN context. We investigate performance and reliability aspects related to SDN data plane operation in software on open source PC-based routers. Our research methodology is based on design, implementation, and experimental evaluation. The experimental platform consists of PC-based routers running open source software in combination with commodity-off-the-shelf (COTS) hardware components. When it comes to performance aspects, we demonstrate that by offloading the lookup from a CPU to a network interface card, the overall performance is improved significantly. For enhanced reliability, we investigate bidirectional forwarding detection (BFD) as a component to realize redundancy with fast failover. We demonstrate that BFD becomes unreliable under high traffic load and propose a solution to this problem by allocating dedicated system resources for BFD control messages. In line with this solution, we extend our architecture for next-generation PC-based routers with OpenFlow support by devising a strategy to efficiently map packet forwarding and application processing tasks onto the multi-core architecture on the PC-based router. This extension would make it possible to integrate BFD effectively into the router platform. Our work demonstrates the potentials of open router platforms for SDN. Our prototypes offer not only high performance with good reliability but also flexibility to adopt new software extensions. Such platforms will play a vital role in advancing towards the future Internet.

Abstract:
Il paradigma “Software-Defined Networking” (SDN) ha suscitato recentemente interesse grazie allo sviluppo e all'implementazione di uno standard tecnologico come OpenFlow. Con il modello SDN viene proposta una rete programmabile tramite la separazione dell’unità di controllo e l'unità di instradamento, rendendo quindi i nodi di rete (come ad es. router o switch) esclusivamente hardware che inoltra pacchetti di dati secondo le regole dettate dal controller. OpenFlow rappresenta lo standard dominante nella tecnologia SDN in grado di far comunicare l'unità controller e l'hardware di uno o più nodi di rete. L'utilizzo di OpenFlow consente maggiore dinamicità e agevolazione nella personalizzazione della rete attraverso un'interfaccia utente, includendo svariate funzioni quali la modifica e l’automatizzazione delle regole di instradamento, la creazione di una rete virtuale dotata di nodi logici o la possibilità di monitorare il traffico accrescendo la sicurezza della propria rete.

Abstract:
Det här arbetet handlar om en mjukvara vars mål är att tillhandahålla syntaxträning inom routeradministration inriktad mot målgruppen studenter. Mjukvaran har programmerats från grunden i programmeringsspråket Python och är menad att erbjuda ett simplistiskt användargränsnitt. Programmeringen har resulterat i ett program som döpts till Routersyntax och består av två delar: ett klientprogram och ett serverprogram. Både klientprogrammet och serverprogrammet går att installera och köra i flera olika operativsystemmiljöer, med främsta fokus på Windows, Ubuntu Linux och OS X. Det är simplistiskt utformat, enkelt att installera och köra, samt gratis att använda för studenter. Förhoppningen är att användaren med hjälp av syntaxträningsmjukvaran ska få en chans att träna sina färdigheter i att skriva routerkommandon för användning av studenter i universitetskurser.
This report explains the implementation and purpose for the computer software called Routersyntax that aims to assist students in exercising router command syntax. Written in Python, the software uses a simplistic command line-driven user interface, designed specifically for routing administration training. The software is divided into two parts: a client and a server. Using the router syntax software, users get an opportunity to try to improve their skills in administering router hardware by exercising router command input in an environment which is free to use for students. The aim is for the software to require nothing but Python and a Python-compatible operating system to run. It supports Windows, Ubuntu Linux and OS X out of the box.

Abstract:
Software-defined Networking (SDN) is an emerging trend in communication networks that facilitates decoupling the control and data plane of multilayer switches. A logically centralized controller hosted on a server configures the forwarding tables (flow tables) of switches in order to route the various data flows.  To implement SDN, OpenFlow technology has been adopted by packet switching vendors as it provides increased flexibility for the control and management of a packet switched domain. OpenFlow technology provides flow based switching that is controlled by a network management control application running in an OpenFlow controller. In this thesis work we investigate how an OpenFlow Controller communicates with a legacy network via the OSPF routing protocol, how the size of the OpenFlow network effects the resources (memory and CPU) of a legacy router to whom the controller communicates. Also we examine bandwidth utilization of the link (between the OpenFlow network and legacy router). The main goal of this thesis is to find methods to reduce the consumption of resources of a legacy router. This study shows that the size of OpenFlow network directly affects the usage of the link’s bandwidth, and the memory and CPU usage of a legacy router. Aggregated information from the OpenFlow controller which is sent towards the legacy router can reduce the utilization of these resources. Finally we proposed several algorithms and design models that can be implemented for route aggregation in Software-defined Networks.  Implementation of the solutions suggested in this thesis will allow automatic route aggregation in SDN. ISPs deploying SDN architecture could benefit from the proposed design models and route aggregation solution.
Software-definierade nätverk (SDN) är en framväxande trend i kommunikationsnät som underlättar frikoppling kontroll och uppgifter plan flerskiktade switchar. Ett logiskt centraliserad styrenhet på en server konfigurerar vidarebefordran tabeller (flödestabeller) av växlar för att dirigera de olika dataflöden. För att genomföra SDN har OpenFlow teknik har antagits av paketförmedlande leverantörer eftersom det ger ökad flexibilitet för kontroll och förvaltning av en påslagen paket domän. OpenFlow teknik ger flöde baserad omkoppling som styrs av ett nätverk ledningens kontroll som körs i en OpenFlow controller. I detta examensarbete undersöker vi hur en OpenFlow Controller kommunicerar med ett äldre nätverk via OSPF routing protokoll, hur storleken på OpenFlow nätverkseffekter de resurser (minne och CPU) av en äldre router till vilken styrenheten kommunicerar.  Också vi undersöker bandbreddsutnyttjandet av sambandet (mellan OpenFlow nätverket och äldre router). Det huvudsakliga målet med detta examensarbete är att hitta metoder för att minska konsumtionen av resurser från en äldre router. Denna studie visar att storleken på OpenFlow nätverk direkt påverkar användningen av länkens bandbredd och minne och CPU-användning av en äldre router. Samlad information från OpenFlow styrenhet som sändes mot äldre router kan minska utnyttjandet av dessa resurser. Slutligen föreslog vi flera algoritmer och modeller konstruktion som kan genomföras för route aggregation i Software Defined-nätverk. Genomförandet av de lösningar som föreslås i denna avhandling kommer att möjliggöra automatisk route aggregation i SDN. Internetleverantörer distribuerar SDN arkitektur kunde dra nytta av den föreslagna utformningen modeller och route aggregation lösning.

Abstract:
Existen numerosos trabajos que estudian o tratan la realización software de los protocolos de comunicaciones para el acceso a la Internet-TCP/IP. Sin embargo, no conocemos ninguno que modele de forma general y precisa la ejecución de este software.
La presente tesis aporta una caracterización detallada de la ejecución de la realización software de los mencionados protocolos sobre un computador personal y bajo un sistema operativo UNIX. Esta caracterización muestra cómo varía el rendimiento del sistema en función de la velocidad de operación de la CPU, las características del subsistema de memoria, el tamaño de los paquetes y otras variables de importancia para la remisión, autenticación y cifrado de paquetes IP.
En otros trabajos se proponen adecuaciones o extensiones a la realización software de los mencionados protocolos que permiten que un software router provea de comunicaciones con diversos niveles asegurados de calidad mediante el uso de mecanismos de planificación para la unidad central de procesamiento. Sin embargo, en dichos trabajos no se contempla la planificación del uso del bus de entrada/salida.
Los resultados derivados de nuestro modelo demuestran que, para sistemas que usan CPUs con frecuencias de reloj superiores a 1 GHz, la planificación conjunta de la CPU y el bus de entrada salida es indispensable para la provisión de comunicaciones con diversos niveles asegurados de calidad. Dichas frecuencias de reloj son comunes en los sistemas comerciales actuales, por lo que consideramos que es un problema de gran interés. En la tesis proponemos un mecanismo que consigue garantías de utilización del bus de entrada/salida mediante la modificación de los drivers de los interfaces de red.
Three are the main contributions of this work. In no particular order:
" A detailed performance study of the software implementation of the TCP/IP protocols suite, when executed as part of the kernel of a BSD operating system over generic PC hardware.
" A validated queuing network model of the studied system, solved by computer simulation.
" An I/O bus utilization guard mechanism for improving the performance of software routers supporting QoS mechanisms and built upon PC hardware and software.
This document presents our experiences building a performance model of a PC-based software router. The resulting model is an open multiclass priority network of queues that we solved by simulation. While the model is not particularly novel from the system modeling point of view, in our opinion, it is an interesting result to show that such a model can estimate, with high accuracy, not just average performance-numbers but the complete probability distribution function of packet latency, allowing performance analysis at several levels of detail. The validity and accuracy of the multiclass model has been established by contrasting its packet latency predictions in both, time and probability spaces. Moreover, we introduced into the validation analysis the predictions of a router's single queue model. We did this for quantitatively assessing the advantages of the more complex multiclass model with respect to the simpler and widely used but not so accurate, as here shown, single queue model, under the considered scenario that the router's CPU is the system bottleneck and not the communications links. The single queue model was also solved by simulation.
Besides, this document addresses the problem of resource sharing in PC-based software routers supporting QoS mechanisms. Others have put forward solutions that are focused on suitably distributing the workload of the CPU-see this chapter's section on "related work". However, the increase in CPU speed in relation to that of the I/O bus-as here shown-means attention must be paid to the effect the limitations imposed by this bus on the system's overall performance. We propose a mechanism that jointly controls both I/O bus and CPU operation. This mechanism involves changes to the operating system kernel code and assumes the existence of certain network interface card's functions, although it does not require changes to the PC hardware. A performance study is shown that provides insight into the problem and helps to evaluate both the effectiveness of our approach, and several software router design trade-offs.

Abstract:
As the performance of PCs is increasing it is of great interest to use these cheap devices as routers,which traditionally consisted of more expensive and customized hardware for that purpose. Thesoftware was also traditionally proprietary and thereby costly, but as the open source communityhas grown there have been development of open source solutions that can perform the task ofacting as a router. However as there are so many solutions out there, it can be hard for the potentialusers to choose which particular solution to use, without having to put in too much work intogetting a fully functional router solution. This study achieved this purpose by benchmarking themost popular open source software routers, in terms of performance and scalability as well asproviding a brief analysis of their basic security features. The routers that were studied wasClearOS, Untangle NG Firewall and IPFire, and after the study was complete IPFire was consideredthe superior with ClearOS as the second and Untangle as third and last.

Abstract:
The rapid growth in population and related demand for travel during the past few decades has had a catalytic effect on traffic congestion, air quality, and safety in many urban areas. Transportation managers and planners have planned for new facilities to cater to the needs of users of alternative modes of transportation (e.g., public transportation, walking, and bicycling) over the next decade. However, there are no widely accepted methods, nor there is enough evidence to justify whether such plans are instrumental in improving mobility of the transportation system. Therefore, this project researches the operational performance of urban roads with heterogeneous traffic conditions to improve the mobility and reliability of people and goods. A 4-mile stretch of the Blue Line light rail transit (LRT) extension, which connects Old Concord Rd and the University of North Carolina at Charlotte’s main campus on N Tryon St in Charlotte, North Carolina, was considered for travel time reliability analysis. The influence of crosswalks, sidewalks, trails, greenways, on-street bicycle lanes, bus/LRT routes and stops/stations, and street network characteristics on travel time reliability were comprehensively considered from a multimodal perspective. Likewise, a 2.5-mile-long section of the Blue Line LRT extension, which connects University City Blvd and Mallard Creek Church Rd on N Tryon St in Charlotte, North Carolina, was considered for simulation-based operational analysis. Vissim traffic simulation software was used to compute and compare delay, queue length, and maximum queue length at nine intersections to evaluate the influence of vehicles, LRT, pedestrians, and bicyclists, individually and/or combined. The statistical significance of variations in travel time reliability were particularly less in the case of links on N Tryon St with the Blue Line LRT extension. However, a decrease in travel time reliability on some links was observed on the parallel route (I-85) and cross-streets. While a decrease in vehicle delay on northbound and southbound approaches of N Tryon St was observed in most cases after the LRT is in operation, the cross-streets of N Tryon St incurred a relatively higher increase in delay after the LRT is in operation. The current pedestrian and bicycling activity levels seemed insignificant to have an influence on vehicle delay at intersections. The methodological approaches from this research can be used to assess the performance of a transportation facility and identify remedial solutions from a multimodal perspective.

Patel, Yusef. File to Factory: A case study of automated prefabrication house-building methods for small-to-medium enterprises. Unitec ePress, December 2017. http://dx.doi.org/10.34074/ocds.0823.

Full text
Abstract:
The Eco-Digital Fabrication (EDFAB) research project aimed to investigate how automated prefabrication technologies and off-the-shelf construction products can be employed to disrupt building industry norms. The aim of this research – conducted at the University of Auckland and Unitec Institute of Technology from 2014 onward – was to provide small-to-medium enterprises in the construction industry with a pathway to upskill and increase construction productivity through the use of these processes. The availability of automated machines and easy-to-use fabrication software is increasing dramatically and this can be paired with readily available construction products to produce novel mass-customised housing solutions. The application of basic automated technologies – such as CNC (Computer Numerical Control) routers – allowed researchers to create ‘recipes’ that can be adopted and adapted relatively easily. By no means did the research favour digital manufacture or assembly processes over traditional analogue construction techniques – the goal was to provide logical, productive and accessible blended solutions for greater affordability and flexibility in design. For example, the designed experiments were required to be built from readily available products, and used simple readymade screw fixings rather than digitally produced custom fixings or joining mechanisms. The research project aimed to generate discussion and provide recommendations on how the construction industry might support the adoption of automated prefabrication technology in small-to-medium enterprise (SME).

Full text
Abstract:
Over the years, public transit agencies have been trying to improve their operations by continuously evaluating best practices to better serve patrons. Washington Metropolitan Area Transit Authority (WMATA) oversees the transit bus operations in the Washington Metropolitan Area (District of Columbia, some parts of Maryland and Virginia). One practice attempted by WMATA to improve bus travel time and transit reliability has been the implementation of designated bus lanes (DBLs). The District Department of Transportation (DDOT) implemented a bus priority program on selected corridors in the District of Columbia leading to the installation of red-painted DBLs on corridors of H Street, NW, and I Street, NW. This study evaluates the impacts on the performance of transit buses along with the general traffic performance at intersections on corridors with DBLs installed in Washington, DC by using a “before” and “after” approach. The team utilized non-intrusive video data to perform vehicular turning movement counts to assess the traffic flow and delays (measures of effectiveness) with a traffic simulation software. Furthermore, the team analyzed the Automatic Vehicle Locator (AVL) data provided by WMATA for buses operating on the study segments to evaluate bus travel time. The statistical analysis showed that the vehicles traveling on H Street and I Street (NW) experienced significantly lower delays during both AM (7:00–9:30 AM) and PM (4:00–6:30 PM) peak hours after the installation of bus lanes. The approximation error metrics (normalized squared errors) for the testing dataset was 0.97, indicating that the model was predicting bus travel times based on unknown data with great accuracy. WMATA can apply this research to other segments with busy bus schedules and multiple routes to evaluate the need for DBLs. Neural network models can also be used to approximate bus travel times on segments by simulating scenarios with DBLs to obtain accurate bus travel times. Such implementation could not only improve WMATA’s bus service and reliability but also alleviate general traffic delays.

Enhanced molecular-based (MLST/whole genome) surveillance and source attribution of Campylobacter infections in the UK. Food Standards Agency, July 2021. http://dx.doi.org/10.46756/sci.fsa.ksj135.

Abstract:
This human campylobacteriosis sentinel surveillance project was based at two sites in Oxfordshire and North East England chosen (i) to be representative of the English population on the Office for National Statistics urban-rural classification and (ii) to provide continuity with genetic surveillance started in Oxfordshire in October 2003. Between October 2015 and September 2018 epidemiological questionnaires and genome sequencing of isolates from human cases was accompanied by sampling and genome sequencing of isolates from possible food animal sources. The principal aim was to estimate the contributions of the main sources of human infection and to identify any changes over time. An extension to the project focussed on antimicrobial resistance in study isolates and older archived isolates. These older isolates were from earlier years at the Oxfordshire site and the earliest available coherent set of isolates from the national archive at Public Health England (1997/8). The aim of this additional work was to analyse the emergence of the antimicrobial resistance that is now present among human isolates and to describe and compare antimicrobial resistance in recent food animal isolates. Having identified the presence of bias in population genetic attribution, and that this was not addressed in the published literature, this study developed an approach to adjust for bias in population genetic attribution, and an alternative approach to attribution using sentinel types. Using these approaches the study estimated that approximately 70% of Campylobacter jejuni and just under 50% of C. coli infection in our sample was linked to the chicken source and that this was relatively stable over time. Ruminants were identified as the second most common source for C. jejuni and the most common for C. coli where there was also some evidence for pig as a source although less common than ruminant or chicken. These genomic attributions of themselves make no inference on routes of transmission. However, those infected with isolates genetically typical of chicken origin were substantially more likely to have eaten chicken than those infected with ruminant types. Consumption of lamb’s liver was very strongly associated with infection by a strain genetically typical of a ruminant source. These findings support consumption of these foods as being important in the transmission of these infections and highlight a potentially important role for lamb’s liver consumption as a source of Campylobacter infection. Antimicrobial resistance was predicted from genomic data using a pipeline validated by Public Health England and using BIGSdb software. In C. jejuni this showed a nine-fold increase in resistance to fluoroquinolones from 1997 to 2018. Tetracycline resistance was also common, with higher initial resistance (1997) and less substantial change over time. Resistance to aminoglycosides or macrolides remained low in human cases across all time periods. Among C. jejuni food animal isolates, fluoroquinolone resistance was common among isolates from chicken and substantially less common among ruminants, ducks or pigs. Tetracycline resistance was common across chicken, duck and pig but lower among ruminant origin isolates. In C. coli resistance to all four antimicrobial classes rose from low levels in 1997. The fluoroquinolone rise appears to have levelled off earlier and among animals, levels are high in duck as well as chicken isolates, although based on small sample sizes, macrolide and aminoglycoside resistance, was substantially higher than for C. jejuni among humans and highest among pig origin isolates. Tetracycline resistance is high in isolates from pigs and the very small sample from ducks. Antibiotic use following diagnosis was relatively high (43.4%) among respondents in the human surveillance study. Moreover, it varied substantially across sites and was highest among non-elderly adults compared to older adults or children suggesting opportunities for improved antimicrobial stewardship. The study also found evidence for stable lineages over time across human and source animal species as well as some tighter genomic clusters that may represent outbreaks. The genomic dataset will allow extensive further work beyond the specific goals of the study. This has been made accessible on the web, with access supported by data visualisation tools.
