Abstract

The invention provides an organization method and device for route filtering rules, which are applied to a router. The method comprises the following steps: reading pre-configured filtering rules stored in a database in sequence; finding nodes, which are matched with the filtering rules of corresponding network segments, on a preset binary tree based on network segments corresponding to the read filtering rules, wherein each node on the binary tree corresponds to one network segment; incrementally adding the read filtering rules to adding nodes. By adopting the technical scheme, the matching efficiency can be increased greatly under the condition that a large number of route filtering rules are configured on the router and the configuration is changed frequently.

Description

Technical field [0001] This application relates to the field of network communication technology, and in particular to an organization method and device for implementing routing filtering rules. Background technique [0002] Route filtering is a function in the network. The router learns and filters the received routing information to better adjust the network topology. [0003] Routing filtering technology generally includes two links, the configuration of routing filtering rules and the application of configured routing filtering rules to filter routing information. In specific implementation, the user presets the matching conditions and matching priority of each matching item, and then, when performing matching, the network segments to be matched are sequentially matched according to the set matching conditions. [0004] During route filtering, when the network segments to be matched are matched sequentially, the matching efficiency is low when the matching conditions change freq...
