Method and system for automatically negotiating connectivity detection time of MPLS network

Abstract

The invention discloses a method and a system for automatically negotiating connectivity detection time of an MPLS network. The method comprises the steps that a first node in the MPLS network sends a negotiation request message including a sending period and a receiving period to a second node; the second node sends a negotiation response message including the sending period and the receiving period to the first node after receiving the negotiation request message; the second node determines a new sending period and a new detection period for connectivity detection of the MPLS network according to the sending period and the receiving period of the second node and the sending period and the receiving period of the first node in the negotiation request message; the first node determines a new sending period and a new detection period for connectivity detection of the MPLS network according to the sending period and the receiving period of the first node and the sending period and the receiving period of the second node in the negotiation response message. The method and the system achieve the purposes of automatic detection time negotiation and bidirectional detection.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for automatically negotiating MPLS network connectivity detection time. Background technique [0002] With the development of communication technology, packet transport network PTN and Internet protocol IP / multi-protocol label forwarding MPLS services are constantly merging and developing. MPLS TP OAM is used more and more in the MPLS TP networking environment. Because MPLS TP OAM can achieve 50ms carrier-grade OAM and protection mechanism, it has the advantages of natural "adaptation" to packets and connection-oriented multi-service support. Now it has become the mainstream technology choice of operators. [0003] At present, when MPLS TP OAM is deployed in an MPLS TP network to detect network connectivity, it is necessary to manually configure the network nodes to ensure the sending and receiving time of the connectivity detection message CCM sent by both parties,...

Problems solved by technology

[0003] At present, when MPLS TP OAM is deployed in an MPLS TP network to detect network connectivity, it is necessary to manually configure the network nodes to ensure the sending and receiving time of the connectivity detection message CCM sent by both parties, which increases the difficulty of deployment and misoperation sex

[0004] At the same time, the existing technology can only detect according to the configured detection time, and the nodes at both ends can only be detected in one detection cycle, which cannot realize separate detection
