Paper Abstract

Link management protocol (LMP) is proposed in generalized MPLS in order to manage the links between adjacent nodes. IETF specifies four basic functions in relevant drafts: control channel management, physical connectivity verification of the data links, link property correlation, downstream alarms and link failure localization. In this paper we discuss LMP and bring forward two new functions: link protection and restoration, and service-relational links. The extension makes the optical network more reliable and more flexible to different kinds of services.
