MPLS(Multi protocol Label Switching) is standard skill for added to speed and control the Network Traffic. MPLS concerned the routing protocol to relative Pack line, Each Pack composed label and node, saved the time to seek the address of node. MPLS worked IP, ATM and Network protocol of flame rely. MPLS is Network OSI suport model, 2Layer send to most of Packinsted of 3Layer Switching. MPLS is added speed Traffic of QoS and effective controled the Network.

In the NGN, QoS must be offered. We try to apply QoS technology and MPLS which makes them possible to support rapidly increasing traffic and franc engineering to maintain steady infra to the environment of MPLS traffic engineering. In this paper, we supplement the defect of the traditional MPLS traffic engineering and apply the technology of QoS. To construct far more steady infra, we suggest the way of its development and advanced protocol(ERSVP) compared to traditional protocol.

To support abruptly increasing data traffic in these days. network management is needed. And also to maintain the steady infra, there is MPLS need which can support traffic engineering. It's necessary that MPLS doesn't only manage network to support recently booming data traffic, but has capacity to support traffic engineering to keep static infrastructure. Traffic engineering, method that a large-scale user shifts traffic to the beforehand designated routes that pass through specific nodes on network, is operation that is mapping traffic flow to the physical network topology. In this paper, we supplement the defect of the traditional RSVP traffic engineering and to construct far more steady infra, we suggest the way of its development of ERSVP signaling protocol.

본 논문에서는 먼저 Forwarding 방식의 라우팅 프로토콜인 MPLS(Multi-Protocol Label Switching)와 네트웍에서의 Traffic Engineering(TE)에 대한 개괄적인 설명과 함께, MPLS 네트웍 내에서의 트래픽 엔지니어링에 대해 기술한다. 그리고 MPLS 도메인 양 끝단에서 단일 경로의 패킷에 대한 MPLS 헤더의 레이블 번호를 이용한 동일한 패킷인지에 대한 확인 방안과 MPLS 도메인 내에서 Loss Detection 메커니즘을 이용한 효율적인 트래픽 엔지니어링방안을 제안한다. 향후 본 연구 방안을 적용하게 되면, 차등 서비스(Differentiated Services, Diffserv)를 제공하는 네트웍 환경의 핵심 망과 Mobile IP 기반의 무선 네트웍 환경에서 유선 네트웍의 Quality of Service(QoS)를 향상시킬 수 있을 것이다.

Recnetly, the demands of QoS(Quality of Service) and the traffic in network is increased. So, H-MPLS(Hierarchical MPLS) network research what guarantees the scalability is in progress. But, the H-MPLS has a problem of increasing of groups and the links of these group's nodes. It happens a problem that is increasing of H-MPLS setup cost. In this paper, We setup the H-MPLS groups. We use NS simulator in order to analyze the performance and traffic transfer times of each H-MPLS groups. In conclusion, we can find out the elevation of the traffic performance, by increasing a amount of links.

In this paper, we design and implement a MPLS based IP-VPN service module as an application for ACE2000 MPLS system. ACE2000 MPLS VPN service module has been developed using the BGP4 extension protocol. The IP-VPN service module supports differentiated QoS using the MPLS traffic engineering. In addition, it offers a path protection mechanism and the restart mechanism of MPLS system and forwarding engine for supporting a highly reliable service.

Today's Internet is providing a single service which is so-called "best-effort service". Now, multimedia and real-time applications are not only demanding large bandwidth but also requiring high QoS. For this, MPLS and DiffServ technology can be adopted to support more scalability and QoS for data traffic engineering. The DISN(Defense Information Systems Network) supports CBR service for voice traffic and VBR service for data traffic which is best-effort service. We propose how to adopt MPLS and DiffServ technology to support traffic engineering and guarantee QoS in the DISN. A traffic analysis according to prioritized traffic classes is done using OPNET simulation tool for assuring QoS. The result shows that low priority packets are delayed a little bit, but high priority packets are transferred more efficiently than without traffic engineering.gineering.

Today's Internet does not have efficient traffic engineering mechanism to support QoS for the explosive increasing internet traffic such as various multimedia traffic. This functional shortage degrades prominently the quality of service, and makes it difficult to provide multi-media service and real-time service. Various technologies are under developed to solve these problems. IETF (Internet Engineering Task Force) developed the MPLS (Multi-Protocol Label Switching) technology that provides a good capabilities of traffic engineering and is independent layer 2 protocol, so MPLS is expected to be used in the Internet backbone network$\^$[1][2]/. The faults occurring in high-speed network such as MPLS, may cause massive data loss and degrade quality of service. So fast network restoration function is essential requirement. Because MPLS is independent to layer 2 protocol, the fault detection and reporting mechanism for restoration should also be independent to layer 2 protocol. In this paper, we present the experimental results of the MPLS OAM function for the performance monitoring and fault detection 'll'&'ll' notification, localization in MPLS network, based on the OPNET network simulator

MPLS is a integrated technology by using routing function and label swapping in the network layer. Based on the previous forwarding equivalence classes, it adds the fixed length label in ingress of the MPLS domain. For the routing, without the packet header information, it uses label for the forwarding decisions. In this paper, traffic engineering requirements in the MPLS internet will be setup. The traffic engineering function have to be performed previously with the network topology. In addition to, we presents the IP network topology and main function with MPLS signaling protocol.
