Embodiment Construction

[0041] In the embodiment of the present invention, after the establishment of the FA-LSP is completed, the nodes in the second network generate the link attribute information of the FA-LSP according to the network topology information of the second network and the FA-LSP information, and actively use the FA-LSP - the link attribute information of the LSP is sent to the first node or the second node in the first network. Make the first node and the second node in the first network adjacency through the FA-LSP.

[0042]Wherein, the first node is also called the first node, and the second node is also called the last node. The first network and the second network are two different networks in the multi-layer or multi-domain network. When two nodes in the first network are directly connected without a direct link, they are connected through the connection provided by the second network. The second network can provide connections for any two nodes in the first network, and the two...

Abstract

The embodiment of the present invention discloses a link attribute information configuration method, a communication device, and a communication system, wherein the configuration method includes: the node in the second network forwards the adjacent label switching path according to the network topology information of the second network, Generate the link attribute information of the forwarding adjacent label switched path; the node in the second network sends the link attribute information to the first node and / or the second node in the first network, so that the first node in the first network and The second node makes the adjacency by forwarding the adjacency label switched path. The embodiment of the present invention can realize the automatic configuration of link attribute information, without manually querying the link attribute information from the second network and configuring it on the nodes in the first network, thereby improving the configuration speed and efficiency of link attribute information , and avoid errors caused by artificially configuring the link attribute information of the FA-LSP.

Description

technical field [0001] The invention relates to communication technology, in particular to a configuration method of link attribute information, a communication device and a communication system. Background technique [0002] In a Multi-Protocol Label Switching Traffic Engineering (MPLS-TE for short) network with traffic engineering, a signaling protocol such as the Resource Reservation Protocol with Traffic Engineering (Resource Reservation Protocol with TE , hereinafter referred to as: RSVP-TE), to automatically establish a Label Switch Path (Label Switch Path, hereinafter referred to as: LSP), and transmit user service data from one node to another node. Different user service data have different requirements on LSP parameters. For example, for real-time business data such as voice calls (Voice over Internet Protocol, hereinafter referred to as: VoIP), video, etc., the delay of the LSP is required not to be too long; for important business data, it is necessary to ensure...
