Intra-domain and inter-domain network interconnecting method and system thereof

Abstract

The invention discloses a method for interconnecting networks in domains and between domains, which comprises the steps: distributing a RID to each autonomous domain, distributing a rID and an HID to each node device in each domain, storing the mapping relation between the HID and the RID, and between the HID and the rID of each node device, obtaining a communication end RID according to the HID on the communicating end and the stored mapping relation between the HID and the RID when a communication source end is communicated with the communication end, obtaining the rID of the communication end in the autonomous domain according to the mapping relation between the HID and the rID of the communication end, and building communication with the communication end by the communication source end according to the rID of the communication end in the domain and the RID of the communication end the domain. The invention also discloses a system for interconnecting networks in domains and between domains. The routing between the domains is independent from an addressed mode in the domain and details of a routing protocol through the method and the system, and integral interconnection of a heterogeneous network is implemented.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to an intra-domain and inter-domain network interconnection method and system thereof. Background technique [0002] In recent years, the Internet has developed rapidly. The emergence of IPv6 network, ATM network, Ad-hoc network and sensor network makes the traditional Internet show new characteristics and brings many new problems. Among them, how to realize the seamless coverage of various networks on the network layer and establish a routing protocol mechanism with high reliability, high stability and good scalability is an important issue that cannot be avoided in the development of the Internet. [0003] To realize the interconnection and intercommunication of various networks at the network layer, the main problem faced is: how to solve the interconnection and intercommunication between networks with different network address spaces. The current network addre...

Problems solved by technology

[0009] For the three technologies of dual-stack technology, tunnel technology, and network address translation technology, if there is no reasonable plan for the network address allocation of each node in an AS, and the deployment of multi-homing and traffic engineering is unreasonable Such situations will hinder the aggregation of network addresses (that is, network address induction) in the autonomous domain, so that more specific routing information will be exposed in the global routing table, which will lead to problems such as route jitter, slow convergence, and routing table routing in inter-domain routing. A series of stability and scalability issues such as expansion
