MPLS-TP 망을 위한 중앙 집중형 망 구성 프로토콜 설계 및 구현

In this paper, we propose a centralized topology discovery protocol for MPLS-TP networks. LLDP (IEEE 802.1ab) protocol is used to exchange L2 neighbor information in MPLS-TP network. The centralized server collects the L2 neighbor information for all nodes through the proposed G-TOP protocol. The G-TOP protocol is an extension of GMPLS PCEP protocol (RFC 5440) for topology discovery by using the out-of-band communication channel. Based on the L2 neighbor information, the centralized server can construct network topology for the MPLS-TP network.
