Embodiment Construction

[0052] The core idea of ​​the present invention is: by decoupling the user identity information of the IP address and the user address information, and decomposing the role of the IP address for both intra-domain location identification and inter-domain location identification, the inter-domain location is introduced. Identifier (Realm routing Identifier, RID), intra-domain location identifier (routing Identifier, rID) and terminal identifier (Host Identifier, HID), each autonomous domain has a globally unique RID, each host has a globally unique HID, rID only has a local meaning. By introducing the inter-domain location identifier RID, the intra-domain location identifier rID and the terminal identity identifier HID, the communication between two node devices in one autonomous domain and between two node devices belonging to different autonomous domains respectively adopts Different addressing modes are used, so that inter-domain routing completely shields the details of intra...

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...
