BFD/OAM BASED SYSTEM FOR AND BFD/OAM BASED METHOD OF MONITORING FAILURES AND MEASURING PERFORMANCE IN DIFFSERV-OVER-MPLS

摘要

A system for sensing failure as measuring performance based on BFD(Bidirectional Forwarding Detecton)/OAM(Operation, Administration and Maintenance) in a Diffserv-over-MPLS(Multi Protocol Label Switching) network and a method thereof are provided to effectively sense failure as measuring performance in a DIffserv-over-MPLS transmission network, and to use a network processor as adopting independent BFD/OAM at the first and second layers, thereby quickly conducting packet processing and failure sensing functions. A BFD/OAM configuration utility(110) sets BFD/OAM according to setup of a control element, and provides a GUI(Graphic User Interface) with the control element. A BFD/OAM configuration driver(120) takes charge of a handler for notifying of failure. A BFD/OAM core component(130) manages a session of the BFD/OAM, and conducts failure sensing and performance measuring functions by processing received BFD/OAM packets or by generating the BFD/OAM packets. An MPLS core component(140) sets interactive LSPs(Label Switching Paths) for the BFD/OAM, sends the generated BFD/OAM packets to the LSPs, and filters BFD/OAM packets received from the LSPs to deliver the filtered packets to the core component(130), then manages each LSP.
