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.

Abstract

The invention discloses a method and a device for calculating the end-to-end access capability of a network, and relates to the field of communication networks. The method includes: obtaining service data of a specified access device, routing edge and target device; searching and obtaining a routing table from the specified access device to the target device according to the service data of the specified access device, routing edge and target device; Table constructs a topology graph from the specified access device to the target device; performs route traversal from the specified access device to the target device according to the topology graph, and performs parallel calculations on the access capabilities of each node device in the topology graph; and calculates The obtained access capability of each node device obtains the access capability of the specified access device to the target device. The invention reduces the storage and calculation overhead caused by the calculation of the complex relationship of the access network in the prior art, and improves the calculation rate.

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...
