Problems solved by technology

[0010] 1. When there are multiple links between two devices (such as figure 1 In the connection between RT2 and RT4), the above-mentioned existing technology still performs repeated LSA announcements on multiple links, resulting in redundant LSA update messages
[0011] 2. In the ring network of multiple devices (such as figure 1 ), when there are many LSA updates, LSA storms will still be generated
Although this technology can avoid repeated LSA advertisements on multiple links, however, in a ring network of multiple devices (such as figure 1 ), when there are many LSA updates, LSA storms will still be generated

Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0036] In order to reduce the number of LSA flooding in large-scale networking, this application proposes a technical solution for reducing the number of LSA flooding. The relationship between each directly connected neighbor of the device on the area shortest path tree of the device and the device, to determine whether to send the LSA update generated by the device to a specific neighbor on a specific link, that is: to determine the LSA update generated by the device Flooding range, thereby reducing the redundant update of LSA.

[0037] On the basis of the above technical solution, in order to further reduce the redundant update of LSA, this application further proposes: when receiving an LSA update not generated by the device from a neighbor, acco...

Abstract

The invention discloses a method for reducing a link state advertisement (LSA) flooding frequency. The method includes determining an updated LSA flooding range generated by equipment according to the stability of a network topology of a region with the equipment and a relation between the equipment and various straight-through neighbors on the shortest path tree of the region with the equipment. The various straight-through neighbors are arranged on three layers of interfaces. The invention further discloses the equipment for reducing the LSA flooding frequency. According to the technical scheme, the method and the equipment have the advantage that the LSA flooding frequency can be reduced.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a method and device for reducing the number of link state notification flooding. Background technique [0002] The application of network technology in daily work is increasing, which brings great convenience to people's work and life. Major companies are constantly expanding their networks, making the scale of the network constantly expanding. At the same time, in order to increase the stability of the network, redundant backup links and nodes are provided in the network, which leads to further expansion of the network scale. In large-scale networks, static routing and RIP protocols cannot be used due to their own defects, while link-state-based dynamic routing protocols (such as OSPF, ISIS) can well support large-scale network environments, And it can provide fast convergence speed, and is more and more widely used. But in a large-scale network environ...
