End-to-end access capability calculating method of network

Abstract

The invention, which relates to the field of the communication network, discloses an end-to-end access capability calculating method of a network. The method comprises: obtaining service data of a designated access device, a routing edge and a target device; carrying out searching based on the service data of the designated access device, the routing edge and the target device to obtain a routing table from the designated access device to the target device; constructing a topological graph from the access device to the target device based on the routing table; carrying out route traversing from the designated access device to the target device based on the topological graph and carrying out parallel computing on access capabilities of all node devices in the topological graph; and acquiring the access capability from the designated access device to the target device according to the access capabilities, obtained by calculation, of all node devices. Therefore, high storage and computing costs caused by computing of the complex relationship of the access network in the prior art can be reduced and the computing efficiency can be improved.

Description

technical field [0001] The invention relates to the field of communication networks, in particular to a method and device for calculating end-to-end access capabilities of a network. Background technique [0002] With years of network evolution and business development, the communication network has shown that the network resource division has a wide area, complex connections, and multiple types of equipment (for example, in terms of providing access capabilities to users, there are copper cable networks, optical cable networks, etc.) and other industry characteristics. The communication network is topological, and the relationship between various recording resources from the central office to the user end is complex and the data is huge. It is difficult to calculate the network topology end-to-end through a fixed method. For example, figure 1 It is a data model diagram schematically showing communication network resources in the prior art. in, figure 1 describes the ori...

Problems solved by technology

However, due to the complexity of its networking, operators cannot accurately provide orderable product capabilities

At present, operators adopt unconditional installation. If resources are insufficient, the construction period will be too long and user perception will be poor

The traditional calculation method needs to go through the data of the entire network, from the user access node to the central office to perform ergodic calculations on the equipment providing capabilities, which requires a very large amount of calculation, time-consuming, and poor application support.
