Abstract:

The rapid development of network raise the role of WAN. As a large-scale backbone network, the failure of network components can lead to huge loss of data and revenue. How to improve the data switching speed and Quality of Service of network data is more and more important problem which Internet Server Provides cared. Multi-Protocol Lable Switching (MPLS) is a new WAN technology which is currently being standardized by IETF. This paper analysise the architecture of MPLS and describe the mechanism of label switching protocol. In addition, this study analyses the encapsulation of data packet at the Label Switching Routers which is on the boundary of MPLS network. A Label Switching Path (LSP) is built by Label Distribute Protocol in core network. A conclution of “one time routed, more times switching” routed was reached.

Abstract:

Multi-protocol label switching (MPLS) is a promising solution to implement high-speed internet protocol (IP) networks by reducing the layer number. To meet the increasing demand for data traffic, optical packet switching (OPS) is integrated under IP to provide high bandwidth to end users. Generalized MPLS (GMPLS) is perfectly compatible with the routing algorithm in IP/MPLS as it supports packet-switching functions. In this paper, we investigate the label stacking scenarios in GMPLS networks. In GMPLS, label stacking is done to reduce the node complexity by appending multiple labels to a single packet. Wavelength-division multiplexing (WDM) and optical code-division multiplexing (OCDM) signals have been widely used as identifying labels. As the labels can be permutated among the wavelengths or code dimensions, the structure of a label stack can be varied. However, studies on the relationship between label stacking scenarios and network performance are limited. To investigate this issue, we propose three label stacking models: sequential code distribution; sequential wavelength distribution, and random label distribution. The simulation results show that the sequential wavelength assignment, wherein the labels are uniformly distributed among the wavelengths, exhibits the best system performance in terms of the label-error rate (LER).

Abstract:

Multiprotocol Label Switching (MPLS) is a switching technology. MPLS-TP is a progressive version of MPLS in the field of packet switched data network. MPLS-TP is a high-end technology which implements network methodologies in a transport layer. For managing virtual private network(VPN) services, MPLS is of developing enthusiasm to the service providers (SPs) and furthermore to VPN customers. MPLS-enabled routers allot a few labels to the packets, and in view of these allocated labels it produces sending decisions. The prime expectation after the MPLS technology is to eliminate the need of OSI model data link layered (layer-2) technology i.e. frame relay, Ethernet, asynchronous transfer mode (ATM). This paper gives data about the components of Multi-Protocol Label Switching (MPLS), correlation of MPLS with traditional Routing and Packet Switching, MPLS label format and MPLS operation.

Abstract:

We present packet switching applications based on extended spectral-amplitude-coding (SAC) labels in generalized multi-protocol label switching (GMPLS) networks. The proposed approach combines the advantages of wavelength-division multiplexing (WDM) and optical code-division multiple access (OCDMA). The extended SAC labels preserve the orthogonal property to avoid the effect of multiple access interference (MAI) shown at the decoder. We investigate the node architecture of label generation/recognition based on arrayed waveguide grating (AWG). Combining cyclic-shifted maximal length sequence (MLS) codes with the wavelength routed property of AWG simplifies the node structure. The simulation results show that the proposed labels achieve good performances against receiver noise due to the low average cross-correlation values. Under a given bit-error-rate (BER), the switching efficiency of the extended SAC labels outperforms the previous OCDMA schemes, as the network nodes are capable of processing a large number of labels simultaneously.

Abstract:

An essential solution is available in Multi-protocol label switching (MPLS), which solve the problems faced by present-day networks: speed, scalability, quality-of-service (QoS) management, and traffic engineering. This paper is an extension of work on Fuzzy based Packet Scheduling Algorithm (FPSA) combined with Packets Processing Algorithm (PPA) in an Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) networks. This will make provision for an intelligent service to the Label Switched Path (LSP) in MPLS networks. Several research work have been proposed on the MPLS Traffic Engineering. However, it is still imperative to further research on the effect of bandwidth increment on the core network using different mechanisms such as the analytical model of MPLS, expert-based packet scheduling algorithm for MPLS QoS support. Since MPLS is not able to provide intelligent routing, it is necessary to propose an intelligent expert system of FPSA combined with PPA. And analytical model of packet forwarding in the MPLS network would be given to provide suitable solution to traffic congestion and reliable services. Furthermore, the network model created using Network Simulator (NS 2), which carries non-real time application such as File Transfer Protocol (FTP) with bandwidth variations. The results obtained from trace files are interpreted by AWK script and used for the further analysis.

Abstract:

Using dominating set can aggregate the complex physical network topologies into simple virtual topologies and reduce the cost of the networks. In the Multi-Protocol Label Switching (MPLS) network, the dominating set constructed based on label router can effectively aggregate MPLS network topology and reduce the amount of Label Switching Path (LSP), so as to save the expenses of network maintain information. However, simply considering the size of dominating set can't guarantee the best performance of the networks after aggregating. Therefore, an improved algorithm based on breadth-first search spanning tree is proposed, considering the size of the dominating set, bandwidth performance of the nodes and path length between nodes, which can effectively extend the MPLS network, with excellent bandwidth performance and reduce the data transmission delay.

Abstract:

Generalized multi-protocol label-switching (GMPLS) provides packet-switching with multiple speeds and quality-of-services (QoSs). Packet buffering in GMPLS reduces packet loss by resolving the conflicts between packets requesting for a common channel. Presently, due to the diversity of multimedia applications, enabling multiple services in networks has become necessary. In this paper, a family of codes known as composite maximal-length sequence (CMLS) codes is introduced into an optical buffering scheme based on code-switching. A given number of available CMLS codes is divided into several code subsets. The buffer selects an unused CMLS code from a code subset and assigns it to the incoming packet. When all codes in a specific subset have been distributed to the queued packets, a free CMLS code in another subset is chosen for the new arrival. To achieve multi-level buffering services, the partition scenario with a lower subset number but with a higher number of codes in an individual subset is used as a code-assigning method for buffering high-QoS users. A two-level buffering system is demonstrated by examining the QoS of each class in terms of packet-dropping probability (PDP). The results show that different levels of PDPs can be effectively supported by a common buffer architecture.

Abstract:

The paper describes the traffic flow problems in telecommunication networks based on the Internet protocol. The main aim of telecommunication network operator today is to offer an SLA (Service Level Agreement) contract to end users, with provided QoS (Quality of Service) for different classes of services. In order to achieve this, it is necessary to establish the routes between marginal network nodes meeting the network traffic requirements and optimizing the network performances free of simultaneous flows conflicts. In DiffServ/MPLS (Multi-Protocol Label Switching) networks traffic flows traverse the network simultaneously and there may come to collision of concurrent flows. They are distributed among LSPs (Labeled Switching Paths) related to service classes. In LSP creation the IGP (Interior Gateway Protocol) uses simple on-line routing algorithms based on the shortest path methodology. In highly loaded networks this becomes an insufficient technique. In this suggested approach LSP need not necessarily be the shortest path solution. It can be pre-computed much earlier, possibly during the SLA negotiation process. In that sense an effective algorithm for collision control is developed. It may find a longer but lightly loaded path, taking care of the collision possibility. It could be a very good solution for collision avoidance and for better load-balancing purpose where links are running close to capacity. The algorithm can be significantly improved through heuristic approach. Heuristic options are compared in test-examples and their application for collision control is explained.

Abstract:

Proses pertukaran informasi dan komunikasi data antar pengguna internet yang dilakukan di lokasi berbeda dan dalam waktu yang bersamaan dapat mengakibatkan semakin tinggi lalu lintas pertukaran informasi dalam suatu jaringan internet. Oleh karena itu, diperlukan adanya suatu mekanisme untuk menentukan dan pemilihan jalur lalu lintas data terbaik untuk dilalui paket data ketika proses pertukaran informasi dan komunikasi data berlangsung. Salah satu mekanisme untuk menentukan dan pemilihan jalur lalu lintas data tersebut adalah dengan menerapkan aturan pada perangkat router. OSPF (Open Shortest Path First) merupakan salah satu routing protocol yang memiliki lisensi kode terbuka (open source), OSPF menggunakan mekanisme routing link-state, kinerja OSPF ditentukan pada kebutuhan dan konsumsi bandwidth. Model optimasi yang dilakukan pada penelitian ini akan memberikan gambaran awal bagaimana suatu routing protocol OSPF bekerja dengan menerapkan teknologi traffic engineering pada wireless mesh network (WMN) menggunakan model multi protokol label switching (MPLS). Kemudian dilakukan analisis dan penilaian terhadap faktor-faktor terkait optimasi routing protocol OSPF dengan membuat rancangan topologi routing protokol OSPF pada jaringan wireless mesh dengan model jaringan MPLS menggunakan tools simulator jaringan.

Abstract:

The paper must have abstract. The rapid growth of networks base on IP, and the current challenge posed by the technological deployment of IPv6 and annexed applications, challenges that must confront the Internet Service Provider and have stimulated the development for rigorous researches on the topic. The Internet Service Providers ISP offer infrastructure for implementation of virtual private network VPN, where is fundamental the definition of routing schemas between the border route of client CE and the provider PE. In this sense, have been proposed different schemas where the new protocols as Open Short Path First version 3 OSPFv3 have a key role. In the context of VPN, the routing protocol BGP is used to distribute the clientâs path, the multi-protocol label switching MPLS is used to send the information packages through the network core in tunnel mode. Originally, only IPv4 was supported and expanded after support OSPFv2 and VPN IPv6. Based on the new specifications in order to support OSPFv3 as a routing protocol PE-CE and the current technological infrastructures begin the process of IPv6 deployment, these elements driving this research which evaluate the performance of routing protocol OSPFv3 on border scenarios MPLS/VPN/IPv6.

Abstract:

enterprise networks. This research focuses on combining advantages from Frame Relay, MPLS and OSPF into a modeled multi-site network. The combination is compared to th original OSPF network and analyzed for its throughput, packet loss, and delay. To meet the demand for efficient and resilient network, and to emphasize the advantages of MPLS-OSP as well as to avoid traffic shifting, specific network topology models are applied: full mesh with virtual circuit in core network connected to OSPF nodes for the rest. From analysis and comparison of network quality values obtained at, this combination attests to be reliable and robust network architecture without trading off its efficiency. The average throughput value of the combination networks was 18.47 bps, which is better compared to the OSPF. The average delay and packet loss from combination network also show better results, which are 59.90ms and 2.01% respectively. The results shows that the combination of Frame Relay, OSPF andMPLS generates better performance as well as significant improvement in networksecurity.

Abstract:

The stability and convergence time become an essential factor in network availability performance. Multiprotocol Label Switching (MPLS) is one of the Virtual Private Network (VPN) technologies that can support the quality of communication media on the high-speed backbone network. Therefore, it is necessary to determine the proper protocol routing in espousing VPN technology based on MPLS supported by direct-link backup to improve network availability in the Data Center. The purpose of this study is comparing the convergence time and Quality of Service (QoS) among the three IGP protocols routing, namely Routing Information Protocol version 2 (RIP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP) based on two autonomous system number using Ring topology design between Data Center and DRC. Network scenario is created using the Graphic Network Simulator (GNS3) application to measure convergence time and QoS parameters of the three protocols routing and the use of MPLS-TE and RR in enhancing MPLS backbone performance. The results revealed that QoS in the three protocols routing has a good quality level according to TIPHON’s standard with the number of indexes up to 3.25 (Good). On the other hand, the fastest convergence time when interruption on the main link (VPN) is EIGRP with convergence time for about 15 seconds.

Abstract:

The growth in the use of multimedia in the educational sector is accelerating rapidly. Multimedia contents are very sensitive in terms of link capacity and other parameters affecting its quality. Due to the lack of existing of a network dedicated for testing and evaluating the e-learning network, there is a need to propose and build a testing environment. In this paper, we present a practical implementation of a testing environment that provide multimedia transmission to aid e-learning over a virtualized Multi-Protocol Label Switching (MPLS) network. The designed network combines hardware and software resources where the source is a real-time video streaming using a professional video camera connected to a virtual network of routers to deliver the multimedia content wirelessly to the intended classroom. The network is successfully implemented and evaluated with acceptable quality according to cisco reference for Quality of Service (QoS) Network Design Guide.

Abstract:

QoS is not a consideration at the beginning of the development of IP networks. However, as its growth and support more services including critical and real-time services, QoS support is indispensable. Multimedia applications require different QoS requirements from simple network applications. Multimedia services need more bandwidth, lossless delivery, and strict delay. IP networks treat all traffic, in the same way, this will be a problem for real-time traffic likes multimedia applications. This project uses Multi-Protocol Label Switching (MPLS) and DiffServ QoS management schemes to meet the quality of service requirement in multimedia networks. The aim of this study shows that two methods can improve network performance for multimedia type applications. An analysis to compare the quality of service guarantees provided by these models using a simulation approach. Based on simulation results and analysis shows that two methods improved network performance for multimedia type applications in massive traffic environments.

Abstract:

Aggregates of real-time traffic may experience changes in their statistical characteristics often manifesting non stationary behavior. In multi protocol label switching (MPLS) networks this type of the traffic is assigned constant amount of resources. This may result in ineffective usage of resources when the load is below than expected or inappropriate performance when the load is higher. In this paper we propose new algorithm for dynamic resource adaptation to temporarily changing traffic conditions. Assuming that network nodes may reallocate resources on-demand using automatic bandwidth adjustment capability of MPLS framework, the proposed algorithm, implemented at ingress MPLS nodes, dynamically decides which amount of resources is currently sufficient to handle arriving traffic with given performance metrics. This decision is then communicated to interior MPLS nodes along the label switched path. As a basic tool of the algorithm we use change-point statistical test that signals time instants at which statistical characteristics of traffic aggregates change. The major advantage of the proposed approach is that it is fully autonomous, that is, network nodes do not need any support from hosts in terms of resource reservation requests. The proposed algorithm is well suited for traffic patterns experiencing high variability, especially, for non stationary type of the traffic.
