Abstract

The invention discloses a network route convergence processing method. According to the method, a preset non-pruning multicast distribution tree is utilized as a fast channel, when network topology is changed, after adjacent devices of a topological change source detect the topological change, a layered service provider (LSP) message is generated according to topological change type, and the LSP message is sent out through the fast channel, and then convergence processing modules on the adjacent devices continue to carry out route convergence process to the topological change event. After a device on the fast channel receives the LSP message, the message is transmitted, and at the same time, the message is sent to the convergence processing modules for route convergence process. The invention further provides a corresponding network route convergence processing device. By means of the network route convergence processing method and the network route convergence processing device, convergence of a whole network is enabled basically not to be limited by network size and topological change positions, and the convergence performance of the whole network is close to the convergence performance of a single device.

Description

technical field [0001] The present invention relates to a communication network, in particular to a network route convergence processing method and device. Background technique [0002] Shortest Path Bridging (SPB) technology and Transparent Interconnection of lots of Links (TRILL) technology are both technologies for building a large two-layer network in a data center. They are all passed through the intermediate system to the intermediate system (Intermediate System to Intermediate System, ISIS) agreement to achieve. SPB technology and TRILL technology have advantages over traditional Layer 2 technologies. For example, they both support Equal-Cost Multipath (ECMP), have high bandwidth utilization, and are suitable for specific networking in data centers. [0003] For data centers, the convergence time of the entire network is a very important performance indicator. In the existing network routing convergence processing, the information diffusion of network topology chang...
