Embodiment Construction

[0028] The dual-homing telecommunications integrated access bearer network can effectively deal with the impact of a single node failure on the entire network. However, the circuit flow of the dual-homing telecommunication network is relatively complicated, and more port resources of the equipment are occupied. Therefore, for different services, selective dual-homing should be based on factors such as importance, traffic, and optical cable routing conditions. The implementation method is as follows:

[0029] (1) In the optical cable structure, the optical cables at each level are connected to the upper-level node in a dual-homing manner.

[0030] (2) On the device network, above the aggregation layer (including the aggregation layer) adopts dual-homing mode to access the upper-level network, and only important customers, 3G base stations, and large-capacity access points at the access layer adopt dual-homing mode connected to the aggregation layer node.

[0031] (3) The opti...

Abstract

The invention belongs to the telecommunication access network field, which particularly relates to a double-returning-type telecommunication synthesis access load-bearing network structure, the invention is characterized in that the invention is divided into a core layer, a backbone layer, a convergent layer and an accessing layer, a lower layer is connected with an upper layer in dual homing form, the backbone layer network doubly returned with the corn layer network, the convergent layer network is doubly returned with the backbone layer network, the access network is doubly returned with the convergent layer network, and a business layer network is doubly returned with the access layer, each two layer surfaces are connected through a double node to resistant network paralysis which is caused by single-node failure.

Description

technical field [0001] The invention belongs to the field of telecommunication access networks, in particular to a dual-homing telecommunication integrated access bearing network structure. Background technique [0002] The existing telecommunications access network is divided into the aggregation layer and the access layer. Most of the services are converged by the equipment of the aggregation layer nodes and then uploaded to the backbone layer. Therefore, the security of the aggregation layer nodes is very important. However, most of the aggregation node computer rooms in the existing telecommunication network are rented private houses, especially the internal and external environment of the computer room is not ideal, there are many hidden dangers such as small power supply capacity, small space in the computer room, and the same routing of optical cables in and out of the aggregation computer room. Cause the sink node to fail. Once the aggregation node fails, it will ca...
