Sensors in the Internet of Things (IoT) generate large amounts of data, which requires high-speed data transmission. In order to achieve the parallel transmissions of the wireless sensor network on the transmission layer, the performance of stream control transmission protocol (SCTP) and transmission control protocol (TCP) in the wireless sensor network under different packet error rates was simulated and compared. A dynamic multipath handover method for SCTP (MS-SCTP) was proposed to improve the transmission performance, which selects the transmission path according to the packet error rate and the retransmission ratio in the sender’s buffer. The TCP and SCTP protocol switching method (TCP-SCTP) was proposed to detect the current network traffic and adjust the MS-SCTP or TCP method. Analysis and simulation results show that MS-SCTP and TCP-SCTP could improve network throughput and reduce packet loss rate. MS-SCTP and TCP-SCTP can be combined with other technologies and channel allocation algorithms to improve network traffic.

Stream Control Transmission Protocol (SCTP) is a new generation of reliable transport layer protocol, unlike TCP, it has new features of multi-homing and multi-streaming, and has good scalability. SCTP is expected to replace TCP as the next generation of universal transport layer protocol. We introduce and analyze the basic structure and features of SCTP, introduce the related research of SCTP, including the implementation method of mobile SCTP and the Concurrent Multipath Transfer mechanism. Finally, compared and analyzed the performance of TCP, SCTP and SCTP-CMT by the ns-2 simulations, results show that in the case of multiple paths are available, the transmission performance of SCTP and SCTP-CMT are both better than TCP.

AbstrakVoIP merupakan aplikasi real time yang kualitasnya sangat tergantung pada delay dan jitter, yang mana hal ini sulit dipenuhi oleh protokol yang bersifat reliable dan memiliki congestion control seperti TCP. Di sisi lain penggunaan UDP yang tidak memiliki congestion control menyebabkan peluang terjadinya congestion pada jaringan sangat besar. Penggunaan SCTP sebagai protokol alternatif juga belum mampu mengakomodasi kekurangan TCP dan UDP. Beberapa hasil penelitian menunjukkan perlu adanya perbaikan ataupun modifikasi pada mekanisme congestion control yang dimiliki oleh SCTP. Penggunaan mekanisme ECN dan AQM pada beberapa penelitian menunjukkan bahwa kedua mekanisme ini dapat menurunkan delay dan jitter. Penelitian ini melakukan pengujian terhadap kualitas VoIP di atas SCTP yang menggunakan ECN dan AVQ pada network simulator NS2. Hasil simulasi menunjukkan bahwa penggunaan mekanisme ECN dan AVQ pada protokol SCTP menghasilkan kualitas VoIP yang lebih baik pada kondisi jaringan yang tidak ideal (high Latency low Bandwidth dan low Latency low Bandwidth dari pada penggunaan protokol SCTP tanpa menggunakan mekanisme ECN dan AVQ. Penelitian ini juga melakukan perbandingan nilai MOS panggilan VoIP SCTP yang menggunakan ECN dan AVQ dengan nilai MOS panggilan VoIP yang menggunakan protokol TCP dan UDP. Hasilnya SCTP dengan ECN dan AVQ mengungguli TCP namun belum dapat mengungguli UDP. Kata kunci— VoIP, SCTP, ECN, AQM,AVQ. AbstractVoIP is the real time applications that are highly dependent on the quality of delay and jitter, which it is difficult to be met by protocol that has reliable data transfer feature and congestion control such as TCP. On the other hand the use of UDP that has no congestion control make chance of causing congestion in the network is very large. The use of SCTP as an alternative protocol was also not able to accommodate the weaknesses of TCP and UDP. Some research shows that repairs or modifications to the SCTP congestion control mechanism is needed.The Use of ECN and AQM in some studies show that these two mechanisms can reduce delay and jitter. This study tested the quality of VoIP over SCTP with ECN and AVQ, in NS2. Simulations carried out by independent replication technique, and the results showed that ECN and AVQ can increase the value of MOS VoIP calls significantly in non ideal network scenarios. This study also did comparison of SCTP MOS that uses ECN and AVQ with MOS values VoIP using TCP and UDP. The result showed that SCTP with ECN and AVQ outperform TCP but can not surpass UDP yet. Keywords— VoIP, SCTP, ECN, AQM,AVQ.

Using the application of bulk data transfer, we investigate the performance of existing TCP-to-SCTP Translation shim scheme under the scenario of shim rules-table is static (i.e., manual). We find that a potential problem named stale shim rules-table value caused by shim rules-table static configuration, which induces TCP-to-SCTP Translation does not startup in time. Based on this, we present a suggestion called Shim Rules-table Dynamic Configuration (SRDC) for TCP-to-SCTP Translation to implement the real-time startup and to improve the throughput of SCTP association by modify original shim rules-table command list, original socket option, original function of connection( ) and sosend( ).

The smart grid delivers electricity from suppliers to consumers and uses bidirectional communication to exchange real-time information between supply system and smart meters at the user end. With a combined communication infrastructure, smart grid manages the operation of all associated components to provide reliable and supportable electricity supply. The Neighborhood Area Network (NAN) of smart grid supports bi-directional data transfer between smart meters (installed at customer premises) and control center of the utility company through an aggregator. This communication suffers low throughput and excessive delays due to the Head of Line (HOL) blocking when the Transmission Control Protocol (TCP) is implemented for reliability. In this paper we propose SCTP-aware Link Layer Retransmission mechanism (SCTP-LLR) which augments the Stream Control Transmission Protocol (SCTP) with Link Layer Retransmissions at the aggregator. SCTP-LLR uses the multi-streaming feature offered by SCTP and implements link layer retransmissions at the aggregator to mitigate the effect of HOL blocking. We carried out simulations using Network Simulator and compared the performance of SCTP-LLR against TCP and SCTP. Our results show that SCTP-LLR outperforms both TCP and SCTP in terms of throughput and packet delays and is a promising protocol to be implemented in smart grid NAN for reliable and efficient communication.

AbstrakStream Control Transmission Protocol (SCTP) merupakan protokol yang mirip dengan Transmission Control Protocol (TCP) dan User Datagram Protocol (UDP). SCTP merupakan protokol yang bersifat reliable dan connectionless. Protokol ini memiliki kemampuan multistreaming dan multihoming dalam melakukan transmisi data. Penelitian ini merupakan pemodelan terhadap SCTP menggunakan simulator OPNET yang dapat menjadi akselerasi bagi peneliti dalam bidang jaringan. SCTP pada simulator dibangun dengan melakukan modiﬁkasi terhadap TCP. Pemodelan dimulai dengan membangun skenario jaringan dan menentukan bandwidth pada jalur yang akan dilewati oleh paket data.Modiﬁkasi ukuran window dalam penelitian ini menggunakan nilai 1 MMS, 2 MMS hingga 10 MMS pada pengendali kemacetan. Tujuannya adalah untuk melihat pengaruh modiﬁkasi ukuran window terhadap nilai packet loss, delay dan throughput. Hasil pengukuran memperlihatkan bahwa nilai throughput tertinggi terdapat pada Skenario Kedua sebagaimana diperlihatkan pada Tabel 6.4 dengan nilai throughput sebesar 433.566,0244 bit/s. Penggunaan ukuran window dalam pengendali kemacetan dimaksudkan untuk menghindari banjir data pada sisi endpoint yang dapat menyebabkan packet loss. Kata kunci—Pengendali kemacetan, throughput, delay, packet loss, ukuran window, multihoming, SCTP Abstract Stream Control Transmission Protocol (SCTP) is a protocol that is similar to the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). SCTP is a protocol that is both reliable and connectionless. This protocol has the ability multistreaming and multihoming in the transmit data.This research is the modeling of the SCTP using OPNET simulator that can be accelerated for researchers in the ﬁeld of networking. SCTP on the simulator was built to perform modiﬁcations to TCP. Modeling starts with building a network scenarios and determine the bandwidth on the path that will be passed by data packets.Modiﬁcation of window size in this research using 1 MMS, 2 MMS up to 10 MMS on congestion control. The aim is to disclose the effect of modiﬁcation of the window size to the value packet loss, delay and throughput. The measurement results show that the throughput rate is highest in the Second Scenario as shown in Table 6.4 with throughput value of 433.566,0244 bits/s. Using window size in congestion control is intended to prevent a ﬂood of data on the endpoint that can lead to packet loss. Keywords—Congestion control, throughput, delay, packet loss, window size, multihoming, SCTP

The work presents a software system for demonstrating the operation of the SCTP transport protocol in comparison with its better-known analogues – TCP and UDP. To reproduce the operation of the chosen protocol, a socket API was created that describes the operation of SCTP, based on RFC 6458. It also describes the transport protocols that are similar to the protocol that was chosen to improve performance, namely TCP and UDP, their strengths and weaknesses, and what has been improved in SCTP. A test software model is described, which is divided into a client part and a server part, which was created to demonstrate the operation of the SCTP transport protocol. The client part consists in sending a message to the server, which will read this message and reset it. The ability to send using the SCTP protocol directly, or UDP encapsulation, thus encapsulating the SCTP packet into a UDP datagram, has been developed. The efficiency and expediency of using the software model are shown and alternative software models designed to implement the SCTP protocol are considered. The means used to implement this decision are justified as well as the platforms and operating systems on which this solution can be reproduced, other than Windows.

This paper studies the basic features and functions of STCP. The traditional TCP protocol and the basic standard SCTP protocols are simulated respectively. We analysis that when the host has multiple network addresses and there are multiple paths between ends, how do the STCP protocol and TCP protocol perform. For practical implementation, using CWND size parameters show performance of multi path transmission in practice, and compare with the ideal case. The results of the simulation and analysis of multi path transmission under the SCTP agreement have practical significance in the future network with multi path transmission.

Nas redes de dados das operadoras de telefonia celular é fundamental que o protocolo utilizado na comunicação entre terminais seja confiável e seguro e que possa prover o máximo de garantias a integridade dos dados. Os protocolos usualmente utilizados na comunidade científica fazem parte da pilha TCP/IP. O protocolo UDP não acrescenta confiabilidade à rede e apenas implementa a multiplexação. Por outro lado, o protocolo TCP tem a vantagem de ser um protocolo confiável possuindo conexões ponto-a-ponto. Na rede de telefonia celular, considera-se nas maioria das vezes o protocolo TCP e deseja-se que as vantagens de UDP existam no TCP. Desta forma, nessa dissertação optou-se pelo estudo dos protocolos SCTP e XTP por possuírem tais características em comum e acrescentar alguns diferenciais. Entre os recursos que mais de destacam no SCTP estão a transmissão de mensagens indivisíveis, múltiplos fluxos de mensagens por conexão, variação da confiabilidade das mensagens, entre outras. Por outro lado o XTP tem como características trabalhar em aplicações de alto desempenho, e por possuir similaridades com o TCP. A proposta deste trabalho de pesquisa é de prover um estudo empírico utilizando-se dos protocolos TCP, SCTP e XTP. O estudo caracteriza-se por considerar os recursos do SCTP e XTP, a fim de demonstrar em uma rede real interna de uma operadora de telefonia móvel o diferencial dos mesmos suportando protocolos de aplicação e simulando diversas condições de rede.

TCP and UDP are the most popular transport protocols used for end-end data transmission. The rapid growth of internet leads to development of many innovative applications in the current environment. Depending on the functionality of these applications, requirements of transport protocols are changing. TCP is known for its problems with Head Of Line blocking (HOL) and SYN attacks which gives reduced performance, and also doesn’t support Multi-Homing. SCTP is another transport layer protocol similar to TCP which provides end-end communication. It has some unique features like support for Multi-homing and multi-streaming. It also protects better from SYN attacks by using four-way hand shake mechanism during association establishment. As an extension to SCTP, CMT-SCTP was proposed to take full advantage of a multi-homed host by doing load sharing over multiple paths. SCTP is believed to be a next generation transport protocol. This thesis gives an overview of the SCTP protocol and its features focusing on analysing and testing of failover mechanisms provided by SCTP in multi-homed host, evaluating the transmission performance of SCTP vs TCP in a real network environment. This report also gives a theoretical analysis on how SCTP can mitigate SYN attacks by using four-way handshake mechanism and the state of art of CMT-SCTP.

With the obvious evolution and acceleration of smart grid, it is crucial for its success to rely on a solid transmission protocol among its peripherals due to its real time streaming. TCP is the well known traditional transport protocol used for a reliable transmission, and is a major player for smart grid. However, it lacks a fault tolerance transmission method that overcomes potential failures which may mitigate smart grid progress and in its turn decrease its reliability. We propose that smart grid operators utilize SCTP as the principle transport protocol for their smart grid communications, by using the two very significant characteristics offered by SCTP multi-homing and multi-streaming respectively. Thus, we argue that they can override two major obstacles caused by TCP Head of Line Blocking (HLB) and the inability of handling automatically two or more paths to a final destination. Although SCTP resembles TCP in many aspects, SCTP can definitely play a dominant role in many current and future applications due to its key features that do not exist in TCP. We have used ns2.34 simulator as the tool whom we relied on to investigate whether or not smart grid may benefit over TCP by the two SCTP features, and have analyzed the output of simulated results by using other analytical tools. As we obtain results, we argue that smart grid operators should rely on SCTP as a feasible transmission protocol instead of TCP.

Networking research and development have historically focused on increasing network throughput and path resource utilization, which particularly helped bulk applications such as file transfer and video streaming. Recent over-provisioning in the core of the Internet has facilitated the use of interactive applications like interactive web browsing, audio/video conferencing, multi- player online gaming and financial trading applications. Although the bulk applications rely on transferring data as fast as the network permits, interactive applications consume rather little bandwidth, depending instead on low latency. Recently, there has been an increasing concern in reducing latency in networking research, as the responsiveness of interactive applications directly influences the quality of experience. To appreciate the significance of latency-sensitive applications for today's Internet, we need to understand their traffic pattern and quantify their prevalence. In this thesis, we quantify the proportion of potentially latency-sensitive traffic and its development over time. Next, we show that the flow start-up mechanism in the Internet is a major source of latency for a growing proportion of traffic, as network links get faster. The loss recovery mechanism in the transport protocol is another major source of latency. To improve the performance of latency-sensitive applications, we propose and evaluate several modifications in TCP. We also investigate the possibility of prioritization at the transport layer to improve the loss recovery. The idea is to trade reliability for timeliness. We particularly examine the applicability of PR-SCTP with a focus on event logging. In our evaluation, the performance of PR-SCTP is largely influenced by small messages. We analyze the inefficiency in detail and propose several solutions. We particularly implement and evaluate one solution that utilizes the Non-Renegable Selective Acknowledgments (NR-SACKs) mechanism, which has been proposed for standardization in the IETF. According to the results, PR-SCTP with NR-SCAKs significantly improves the application performance in terms of low latency as compared to SCTP and TCP.
Interactive applications such as web browsing, audio/video conferencing, multi-player online gaming and financial trading applications do not benefit (much) from more bandwidth. Instead, they depend on low latency. Latency is a key determinant of user experience. An increasing concern for reducing latency is therefore currently being observed among the networking research community and industry. In this thesis, we quantify the proportion of potentially latency-sensitive traffic and its development over time. Next, we show that the flow start-up mechanism in the Internet is a major source of latency for a growing proportion of traffic, as network links get faster.

To provide Internet applications with good performance, the transport protocol TCP is designed to optimize the throughput of data transfers. Today, however, more and more applications rely on low latency rather than throughput. Such applications can be referred to as data-limited and are not appropriately supported by TCP. Another emerging problem is associated with the use of novel networking techniques that provide infrastructure-less networking. To improve connectivity and performance in such environments, multi-path routing is often used. This form of routing can cause packets to be reordered, which in turn hurts TCP performance. To address timeliness issues for data-limited traffic, we propose and experimentally evaluate several transport protocol adaptations. For instance, we adapt the loss recovery mechanisms of both TCP and SCTP to perform faster loss detection for data-limited traffic, while preserving the standard behavior for regular traffic. Evaluations show that the proposed mechanisms are able to reduce loss recovery latency with 30-50%. We also suggest modifications to the TCP state caching mechanisms. The caching mechanisms are used to optimize new TCP connections based on the state of old ones, but do not work properly for data-limited flows. Additionally, we design a SCTP mechanism that reduces overhead by bundling several packets into one packet in a more timely fashion than the bundling normally used in SCTP. To address the problem of packet reordering we perform several experimental evaluations, using TCP and state of the art reordering mitigation techniques. Although the studied mitigation techniques are quite good in helping TCP to sustain its performance during pure packet reordering events, they do not help when other impairments like packet loss are present.

Cette thèse porte sur une solution multipath pour terminaux mobiles multi-interfaces qui permet l'utilisation de chemin de données parallèles pour obtenir un débit plus élevé ainsi qu'une fiabilité de transmission dans des réseaux sans fil hétérogènes. il propose une solution au niveau de la couche de transport appelée forward prediction scheduling (fps). fps attenue le problème de réception de données dans le désordre en estimant au préalable les retards encourus par les données sur chaque chemin candidat, puis en planifiant la transmission d'un paquet de données de telle sorte qu'il soit reçu en ligne avec les paquets provenant d'autres chemins. L'évaluation préliminaire des performances du fps est effectuée a l'aide du modèle sctp-cmt de ns-2. ceci est ensuite suivi par l'implémentation fps dans la version du noyau linux de sctp (lksctp) et par des tests utilisant un appareil mobile avec un ensemble hétérogène d'interfaces réseau filaires et sans fil. les résultats prouvent les améliorations de performances apportées par le fps face a des taux de retard de trajet élevés et a des liaisons sans fil dynamiques. Une extension inter-couches du mécanisme fps est également proposée, qui contribue a des calculs précis du délai de trajet en utilisant les informations de couche 2 dans les liaisons sans fil 802.11.enfin, une solution multiparti codage réseau axée sur la fiabilité est proposée, qui permet a un hôte multi-interface de transmettre des combinaisons de paquets de données en utilisant ses multiples chemins. à l'aide de résultats préliminaires, il est démontre que l'application du codage linéaire avec le mécanisme améliore considérablement la fiabilité
This thesis deals with a multipath solution for multi-interfaced mobile terminals that enables the use of parallel data paths to achieve higher throughput as well as transmission reliability in heterogeneous wireless networks. it proposes a transport-layer multipath solution called forward prediction scheduling (fps). fps alleviates the out-of-order data reception problem by estimating the delays incurred to data on each candidate path beforehand, and then scheduling the transmission of a data packet such that it is received in line with packets from other paths.preliminary performance evaluation of fps is carried out using ns-2's sctp-cmt model. this is then followed by fps implementation in linux kernel version of sctp (lksctp) and tests using a mobile device with heterogeneous set of wired and wireless network interfaces. the results prove the performance improvements brought by fps in face of high path delay ratios and dynamic wireless links.a cross-layer extension of fps mechanism is also proposed which contributes to accurate path delay calculations using layer-2 information in 802.11 wireless links.finally, a reliability-driven network coding multipath solution is proposed which enables a multi-interfaced host to transmit linearly encoded combinations of original data packets using its multiple paths. with the help of preliminary results, it is shown that the application of linear coding with fps mechanism significantly improves data transmission reliability as well as leads to less out-of-order reception problem

This thesis concerns the security of tomorrow’s peer-to-peer real-time communication in heterogeneous networks. Because of the additional delay caused by inband handshake and the poor compatibilities of some transport protocols, it was determined that existing security protocols such as transport layer security (TLS) and datagram transport layer security (DTLS) are not suitable in such a user scenario and a new security protocol should be designed. This new security protocol is called transport encapsulation security payload (TESP). TESP not only has the advantage of low initialization delay, but also fully supports transport protocols including TCP, UDP, stream control transmission protocol (SCTP), and datagram congestion control protocol (DCCP). Also a security analysis of TESP was carried out and no security flaws were found.

På grund av den adderade fördröjning som orsakas av inbandssignalering och dålig kompabilitet hos många transportprotokoll, så kan man fastställa att existerande säkerhetsprotokoll, såsom "(Datagram) Transport Layer Security" (TLS och DTLS), inte är lämpade för denna typ av kommunikation och att ett nytt säkerhetsprotokoll bör tas fram. "Transport Encapsulation Security Payload" (TESP) är ett sådant protokoll. TESP har inte bara fördelar såsom låg uppstartsfördröjning, utan har också stöd för många transportprotokoll, t.ex. "Transport Control Protocol" (TCP), "User Datagram Protocol" (UDP), "Stream Control Transmission Protocol" (SCTP) och "Datagram Congestion Control Protocol" (DCCP). Även en säkerhetsanalys av TESP har gjorts, där inga säkerhetsproblem har kunnat påvisas.

The need for reliable data delivery at the transport layer for video transmission over IEEE 802.15.4 Wireless Sensor Networks (WSNs) has attracted great attention from the research community due to the applicability of multimedia transmission for many applications. The IEEE 802.15.4 standard is designed to transmit data within a network at a low rate and a short distance. However, the characteristics of WSNs such as dense deployment, limited processing ability, memory, and power supply provide unique challenges to transport protocol designers. Additionally, multimedia applications add further challenges such as requiring large bandwidth, large memory, and high data rate. This chapter discusses the challenges and evaluates the feasibility of transmitting data over an IEEE 802.15.4 network for different transport protocols. The analysis result highlights the comparison of standard transport protocols, namely User Datagram Protocol (UDP), Transport Control Protocol (TCP), and Stream Control Transmission Protocol (SCTP). The performance metrics are analyzed in terms of the packet delivery ratio, energy consumption, and end-to-end delay. Based on the study and analysis that has been done, the standard transport protocol can be modified and improved for multimedia data transmission in WSN. As a conclusion, SCTP shows significant improvement up to 18.635% and 40.19% for delivery ratio compared to TCP and UDP, respectively.

São apresentadas as vantagens do uso de um injetor de falhas de comunicação para o teste da implementação de protocolos de rede. SCTP é um protocolo novo, que oferece serviços semelhantes aos do UDP e do TCP e promete garantir confiabilidade às aplicações de rede. Através de experimentos de injeção de falhas sobre o protocolo SCTP mostra-se como é possível avaliar o comportamento do protocolo na presença de falhas controladas. O injetor FIRMAMENT foi escolhido para os experimentos de teste por estar disponível para uso, por possuir um alto poder de expressão de carga de falhas, por operar diretamente na pilha de protocolos do sistema operacional e pela facilidade com que pode ser configurado para operar com diferentes protocolos de rede.
