Example Embodiment

[0049] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0050] figure 1 It is a functional block diagram of a method for automatically negotiating MPLS network connectivity detection time provided by an embodiment of the present invention, such as figure 1 As shown, the steps include:

[0051] Step 101: In a multi-protocol label forwarding MPLS network, the first node sends a negotiation request message including its sending period and receiving period to the second node, requesting the second node to negotiate a detection time for MPLS network connectivity detection.

[0052] Step 102: After receiving the negotiation request message, the second node sends a negotiation response message including its sending period and rece...

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,...
