Problems solved by technology

[0005] However, the routing tables in the current HSAPN are all implemented by static manual configuration, which will consume a lot of manpower, and the manual routing table configuration is complicated and error-prone; in addition, the prior art does not propose how to implement public telecom packet data Management Control of Dynamic Routing in Network
[0006] On the other hand, with the development of packet networks, various ideas of separation of control and forwarding and centralized routing control have emerged, but no specific method for establishing routing after separation of control and forwarding has been proposed.

Embodiment 1

[0031] The embodiment of the present invention provides a method for establishing a dynamic route. On the Hierarchical Sequential Address Packet Network (HSAPN), before the entire network starts to operate, a CMD (Control Management Device, control management device) and the CMD are first established. The control and management channel between the HSAPN routers in the jurisdiction area; after that, the control management device collects all the link state notification messages in the jurisdiction area, calculates the routing topology map of the jurisdiction area, and calculates the routing table according to the directed graph . Among them, the control and management equipment is centralized control, and a hierarchical structure can also be adopted. see figure 2 , including the following steps:

[0032] Step 101: Establish a control management channel between the CMD and each HSAPN router in the area under the jurisdiction of the CMD.

[0033] The embodiment of the present...

Embodiment 2

[0055] see Figure 5 , this embodiment provides a system for establishing routing, the system includes:

[0056] The router is used to establish a control and management channel between the router and the control and management device that governs the router; send link state notification information to the control and management device through the established control and management channel;

[0057] The control and management device is used to establish the control and management channel between the device and the routers in the area under its jurisdiction; collect the link state notification information sent by the router through the established control and management channel; calculate the jurisdiction according to the received link state notification information The routing topology map of the area;

[0058] The routing calculation device is used to calculate the routing table of each router according to the routing topology graph calculated by the control and management d...

Abstract

The invention discloses a method and system for establishing routing and a control and management device, and belongs to the technical field of packet networks. The method for dynamically establishing routing comprises: establishing a control and management channel between the control and management device and routers in a responsible area of the control and management device; collecting link state notification information sent by the routers through the control and management; calculating a routing topological diagram of the responsible region according to the link state notification information; and calculating routing tables of the routers according to the routing topological diagram. The system for dynamically establishing routing comprises the routers, the control and management device and a routing calculation device. The control and management device comprises a channel establishing module, an information receiving module and a topological diagram calculation module. The method, the system and the control and management device can realize dynamic routing calculation, control and management.

Description

technical field [0001] The present invention relates to the field of packet network technology, in particular to providing a method, system and control management equipment for establishing routing. Background technique [0002] With the development of technology, the telecommunication network has successfully completed the transition from analog technology to digital technology, and is undergoing the transition from TDM (Time-Division Multiplexing) technology to packet switching technology, ATM (Asynchronous Transfer Mode , Asynchronous Transfer Mode) packet technology is a representative of this transition, but due to technical difficulties and unsuccessful commercial operations, the second transition of the telecom network has not been realized. In the early 1990s, the Internet based on IP (IP Protocol) packet technology achieved great success due to the application of Web technology. extend. Therefore, the telecommunication network has introduced IP packet technology a...
