Method for establishing vector connection on vector data communication net

Abstract

The method comprises: according to the connection information initially preset, the calling side takes the name address of called side as the called address to send a call to network; according to the tree-like organizational structure, said network determines the calling path to the called side; through the calling path, said calling side and called side mutually exchange and renew the connection information; according to the renewed connection information, both calling and called sides determine multi communication paths by which the connection information lastly renewed by both calling and called sides composes a vector connection.

Description

technical field [0001] The invention relates to the field of data communication networks, in particular to a method for establishing vector connections on a vector data communication network. Background technique [0002] Telecommunication network and computer network are two main communication networks widely used at present. According to the layering method of ISO, computer network has seven layers. Here, the computer network in the third layer sense is called data communication network. The data communication network composed of deployed electronic equipment and communication lines connected between electronic equipment as required is a network with a certain physical topology. The electronic equipment and communication lines of the data communication network are all related to the physical topology. The information is referred to as "physical topology information of the network". [0003] A modern communication network is functionally divided into a transmission plane a...

Problems solved by technology

However, the early telecommunication network did not distinguish between the transmission plane and the control plane, and the two functions were integrated together, which had serious shortcomings such as complex network equipment, difficult upgrades, and difficult maintenance.

[0005] Drawing on the successful experience of separating the transmission plane and the control plane of the telecommunication network, the data communication network also separates the data transmission and call control functions, and invented the ATM network. As a data communication network, it can build a global network just like the IP network. And it can be extended to user terminals. However, because the ATM network is too complicated, it has not been widely promoted until now, and it is only used in the backbone network of some areas.

The main problem of the ATM network is that the cost of maintaining communication connections in the communication network is too high
