급속히 증가하는 데이터 트래픽을 지원할 수 있도록 네트웍을 관리해야 할 뿐만 아니라 안정적인 인프라를 유지하기 위해 트래픽 엔지니어링을 지원할 수 있는 MPLS가 필요하게 되었다. 트래픽 엔지니어링은 대규모 사용자가 트래픽을 네트웍 상의 특정 노드를 지나는 사전 지정된 경로로 이동시키는 방법으로 트래픽 플로우를 물리적인 네트웍 토폴로지에 매핑시키는 작업이라고 할 수 있다. 본 논문에서는 기존 RSVP의 트래픽 엔지니어링의 단점을 보완하고 보다 안정된 인프라를 구축하기 위해 RSVP 확장 시그널링 프로토콜에 대한 진화방향을 제시하고져 한다.

Network is expected to be developed into optical Internet network collected IP layer and optical layer, but GMPLS is risen at the transitional evolution stage because of the present technology level. GMPLS that MPLS is extended and generalized is able to support not only the packet switching device but also the devices which perform switching in time, wavelength, and space domain. To implement the common control plane to these various switching types, GMPLS extends the existing MPLS signaling and routing protocol. In this paper, we describe the overview of GMPLS technology, and then we will refer to the OSPF(Open Shortest Path First), which was used to exchange the status information of link, as the plan of routing extension to exchange the information of various link type, bandwidth, link protection type etc. And also, we describe the definition of new protocol, so called, LMP that is a signaling protocol for solving complex problem which manages hundreds and thousands of links between two nodes. And we will examine and analyze the plan of signaling protocol extension to apply signaling protocol RSVP-TE(Resource Reservation Protocol) for traffic engineering in MPLS to network, and the message objects and formats associated with modified RSVP.

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.
