Embodiment Construction

[0055] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0056] The SR management node mentioned in the present invention is an SR node elected in the network with a convergence management function, and the SR node is other SR nodes in the network except the SR management node. Wherein, how to select belongs to the well-known technology of those skilled in the art, and its specific implementation is not used to limit the protection scope of the present invention, so it will not be repeated here.

Abstract

The invention discloses an SID allocation method and an SR node. The SID allocation method comprises the steps that: an SR management node obtains address information of the SR node in a network and allocates SID information to the SR node; the SR management node transmits the allocated SID information to each SR node in the network through an IGP message multicasting manner or configuration management message extension. By adopting the SID allocation method, IP configuration, SID configuration and the like do not need to be conducted on nodes or ports on the network, and the automatic allocation and learning of the SID information of the SR nodes without serial number interfaces is achieved. In addition, business channels are established between the SR management node and the SR nodes in the network, thus the automatic establishment of the business channels between an SR control node and the SR nodes is achieved, and the complexity of business channel establishment and configuration is greatly simplified.

Description

technical field [0001] The present invention relates to IP-based transport network (IPRAN) technology, especially a method for allocating SID and SR node. Background technique [0002] At present, on the IP-based transmission network (IPRAN), also known as the unnumbered interface network, there is an automatic establishment and configuration method of the data communication network (DCN, Data Communication Network) management channel, mainly through the automatic setting of the DCN port on each node, the default Generate routing ID (RouterID), through the expansion of Open Shortest Path First (OSPF, OpenShortestPathFirst) protocol, Address Resolution Protocol (ARP, AddressResolutionProtocol), Link Layer Discovery Protocol (LLDP) and other protocols to realize the management IP between nodes Address, DCN port, and MAC address learning, so as to realize the automatic establishment and configuration of DCN channels. [0003] However, for the establishment of service channels ...
