Problems solved by technology

The HSAPN network adopts a hierarchical and orderly coding method and hierarchical routing, so a certain path can be determined according to the address. However, there is no perfect routing table establishment method and corresponding routing method in the current HSAPN network. The current routing table needs to provide the entire The routing information of the router nodes in the network has a large number of routing table entries, and all of them are implemented by static manual configuration, which is complex and error-prone

Embodiment Construction

[0018] Embodiments of the present invention provide a method for establishing a routing table in an HSAPN network, a routing method, and a router. Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the HSAPN network includes at least one HSAPN network, a plurality of IP networks, ATM networks or FR (Frame Relay, Frame Relay) networks, and a plurality of ED (Edge Device, border entity) devices, wherein each HSAPN network also includes Include at least one ADT (Address Translation Entity). The service network of the HSAPN network can be an IP network, an ATM network, or a FR network. Since the IP network is currently the most widely used network, the following mainly uses the IP network as an example to describe. in such as figure 1 In the HSAPN network shown, the IP network is connected to the HSAPN network through ED equipment, all equipment in the HSAPN network a...

Abstract

A routing method and router in Hierarchical and Sequential Address Packet Network (HSAPN) is disclosed. In the method, the current router node receives the message to be forwarded and obtains the HSAPN address of the destination router node from the message; the current router node judges whether the HSAPN address of the destination router node and its own HSAPN address are the same; if yes, it ends the routing of the message; if no, it determines, according to routing rules and a routing table, a next-hop directly-connected neighbor router node and routes the message to the next-hop directly-connected neighbor router node.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for establishing a routing table in a Hierarchical and Sequential Address Packet Network (HSAPN, Hierarchical and Sequential Address Packet Network) network, a routing method and a router. Background technique [0002] With the development of technology, the telecommunication network has successfully completed the first transition from analog technology to digital technology, and is undergoing the second transition from TDM (Time-Division Multiplexing) technology to packet switching technology , ATM (Asynchronous Transfer Mode, Asynchronous Transfer Mode) packet technology is the representative of this transition stage, but due to the difficulty of ATM packet technology and the unsuccessful commercial operation, the second step of the transition from TDM technology to packet switching technology in the telecommunications network has not been realized . [0003] In the ...
