Abstract: This paper introduced the disadvantages of uni-layer.After explaining the characters a nd principles of MPLS which support MPLS traffic engineering, the paper discussed the multi-layer MPLS traffic engineering and gave out examples to illustrate. Then explained the differentias between uni-layer MPLS traffic engineering and m ulti-layer MPLS traffic engineering. Finally, we proposed the domain that we can continue study to end the article.

Traffic Engineering without Congestion Hot Spots in MPLS
A.Padmapriya,,L. Rajeswari
International Journal on Computer Science and Engineering , 2010,
Abstract: Traffic Engineering [1] broadly relates to optimization of the performance of the operational IP network. In networking, network congestion occurs when a link or node is carrying so much data that its quality of service deteriorates. Typical effects include queueing delay, packet loss or the blocking of new connections. A consequence of these latter two is that incremental increases in offered load lead either only to small increases in network throughput, or to an actual reduction in network throughput. This paper discusses methods like PNP approach [2] and HITS method for improving QoS [3], which are used for traffic engineering in MPLS. This paper will examine the two approaches; discuss solutions in both PNP approach and HITS method for improving QoS and point to topics for research and advanced development.

Abstract: MultiProtocol Label Switch (MPLS) has become key IP technology. The challenges of MPLS traffic engineering technology were analyzed. The progress of the research about MPLS traffic engineering was summarized, and classified into four kinds of methods. A functional model of MPLS traffic engineering was proposed. Finally, some personal perspectives and suggestions were proposed.

International Journal of Distributed and Parallel Systems , 2012,
Abstract: Over the last years, we have witnessed a rapid deployment of real-time applications on the Internet as well as many research works about Quality of Service (QoS), in particular IPv4 (Internet Protocol version 4). The inevitable exhaustion of the remaining IPv4 address pool has become progressively evident. As the evolution of Internet Protocol (IP) continues, the deployment of IPv6 QoS is underway.Today, there is limited experience in the deployment of QoS for IPv6 traffic in MPLS backbone networksin conjunction with DiffServ (Differentiated Services) support. DiffServ itself does not have the ability to control the traffic which has been taken for end-to-end path while a number of links of the path are congested. In contrast, MPLS Traffic Engineering (TE) is accomplished to control the traffic and can set up end-to-end routing path before data has been forwarded. From the evolution of IPv4 QoS solutions, we know that the integration of DiffServ and MPLS TE satisfies the guaranteed QoS requirement for realtime applications. This paper presents a QoS performance study of real-time applications such as voiceand video conferencing in terms of Packet Delay Variation (PDV) over DiffServ with or without MPLS TE in IPv4/IPv6 networks using Optimized Network Engineering Tool (OPNET). We also study the interaction of Expedited Forwarding (EF), Assured Forwarding (AF) traffic aggregation, link congestion, as well as the effect of performance metric such as PDV. The effectiveness of DiffServ and MPLS TE integration in IPv4/IPv6 network is illustrated and analyzed. This paper shows that IPv6 experiences more PDV than their IPv4 counterparts.
Analysis of the Similarities and Differences between MPLS Label Distribution Protocols RSVP and CR-LDP
Muhammad Asif,Zahid Farid,Muhammad Lal,Junaid Qayyum
International Journal of Computer Science Issues , 2012,
Abstract: MPLS is a new technology that offers to open up the Internet by providing many additional services to applications using IP. MPLS forwards data using labels that are attached to each data packet. These labels must be distributed between the nodes that comprise the network. Many of the new services that ISPs want to offer rely on Traffic Engineering functions. There are currently two label distribution protocols that provide support for Traffic Engineering: Resource ReSerVation Protocol (RSVP) and Constraint-based Routed Label Distribution Protocol (CR-LDP). Although the two protocols provide a similar level of service, the way they operate is different, and the detailed function they offer is also not consistent. Hardware vendors and network providers need clear information to help them decide which protocol to implement in a Traffic Engineered MPLS network. Each protocol has its champions and detractors, and the specifications are still under development. Recognizing that the choice of label distribution protocol is crucial for the success of device manufacturers and network providers; this White Paper explains the similarities and important differences between the two protocols, to help identify which protocol is the right one to use in a particular environment. Data Connection€ s DC-MPLS family of portable MPLS products offers solutions for both the RSVP and CR-LDP label distribution protocols.
PM2PLS-An Integration of Proxy Mobile IPv6 and MPLS  [PDF]
Carlos A Astudillo,Oscar J Calderon,Jesus H Ortiz
International Journal of Computer Science Issues , 2011,
Abstract: This paper proposes a handover scheme supporting Multi-Protocol Label Switching (MPLS) in a Proxy Mobile IPv6 (PMIPv6) domain that improves the mobility and gives Quality of Service (QoS) and Traffic Engineering (TE) capabilities in wireless access networks. The proposed scheme takes advantages of both PMIPv6 and MPLS. PMIPv6 was designed to provide NETwork-based Localized Mobility Management (NETLMM) support to a Mobile Node (MN); therefore, the MN does not perform any mobility related signaling, while MPLS is used as an alternative tunneling technology between the Mobile Access Gateway (MAG) and the Local Mobility Anchor (LMA) replacing the IP-in-IP tunnels with Label Switched Path (LSP) tunnels. It can also be integrated with other QoS architectures such as Differentiated Services (DiffServ) and/or Integrated Services (IntServ). In this study, we used MATLAB to perform an analysis to evaluate the impact of introducing MPLS technology in PMIPv6 domain based on handover latency, operational overhead and packet loss during the handover. This was compared with PMIPv6, and a PMIPv6/MPLS integration. We proved that the proposed scheme can give better performance than other schemes.
