Identifier addressing method of hierarchical structure

Abstract

The invention discloses an identifier addressing method of a hierarchical structure. The method comprises the following steps: step 1) receiving a request message carrying an identifier of a request network entity; 2) performing identification analysis on an edge router of the control domain to obtain an address, and if the address obtained by analysis is a final destination address, ending the process; otherwise, the address obtained through analysis is the boundary router address of the management domain where the network entity is located, and the step 3) is executed; 3) matching the identifier of the entity in the management domain with the controller storing the related mapping relation of the identifier on a boundary router of the management domain, if the matched controller is found, performing identifier analysis and addressing in the matched controller, and turning to the step 2); otherwise, executing the step 4); step 4) on the administrative domain boundary router, determining an intermediary boundary router corresponding to the identifier; and on the intermediary boundary router, obtaining the management domain boundary router associated with the identifier through the index, and executing the step 3).

Description

Technical field [0001] The present invention relates to the field of network technology and communication technology, in particular to a hierarchical identification addressing method. Background [0002] With the development of new technologies and applications such as the Internet of Things, mobile access, distributed information processing, and massive streaming media, the current computer network performance based on TCP / IP architecture has gradually become the limit, and the contradiction between the massive demand for information content services and the network bandwidth bottleneck is increasingly intensifying. The problem of thin waist of the network due to the IP network structure has become an important factor hindering the development of the current network application layer. Existing Internet TCP / IP architectures have many problems in terms of scalability, mobility, multihoming, and traffic engineering. The IP addresses used by the Internet now have the dual meaning of...

Problems solved by technology

[0005] The first method does not need to rely on parsing services and network addresses, and routes and forwards completely based on identification; but it cannot be better compatible with existing network equipment and network architecture, and there is a large number of identification routing tables, which brings scalability and routing Convergence efficiency problem

The second method can be better compatible with existing network equipment and network architecture, and the underlying mechanism is still based on address routing; but it needs to rely on an external parsing and mapping system, and the security and efficiency of the system will affect the routing process
