Embodiment Construction

[0024] Relevant technical content and detailed description of the present invention, now cooperate accompanying drawing to explain as follows:

[0025] like figure 1 As shown, the present invention divides the integrated network into several management domains, referred to as domains for short, according to the management scope of the mapping server. Each domain is provided with a mapping server, which is responsible for storing and managing the terminal mapping relationship information in the domain. Domain deployment should be completed by the network management department, which can be based on factors such as region and network scale. When each access switching router enters the integrated network, the administrator is required to configure the address of the mapping server in the domain, that is, the switching routing ID of the mapping server. In addition, it needs to be allocated a switching routing ID pool to complete the mapping. Switching Routing Identifier Assignmen...

Abstract

The invention provides a unified network home information diffusing method by using a border gateway protocol (BGP). The invention is characterized in that an access identifier of a terminal comprises a field which is the same as the autonomous number of the home autonomous system for identifying the home domain; the routing upgrading of the border gateway protocol comprises switching routing identifiers of an identifier mapping server of the initial autonomous system; an access switching router reads and maintains the switching routing identifiers capable of arriving at the identifier mapping server of the autonomous system from the border gateway information. The invention can simplify the diffusion of mapping information, show the consistency relationship of routing and mapping in the communication, and the process is easy to manage.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and relates to a method for realizing information diffusion of an integrated network attribution domain. Background technique [0002] The existing Internet is composed of several autonomous domains (AS-Autonomous System), and each autonomous domain has its own AS Number. The inter-domain routing protocol is mainly Board Gateway Protocol (BGP), which is responsible for routing information of each domain spread across domains. BGP is a path vector (Path-Vector) protocol, because the routing information of BGP contains the path attribute called AS_path, which records the AS that this path passes through. In order to spread the inter-domain routing information in the domain and learn rich routing attributes, the routers in the domain generally also need to run the BGP protocol. [0003] Farinacci et al. of the current Cisco company proposed the LISP protocol, which is also a protocol for...
