Data message processing method and system and access service node

Abstract

The invention relates to a data message processing method and system, and a service access node. The method is implemented on the basis of an identity position separation network. A corresponding relation between a domain name and an AID (Access ID) of an end host is stored in a DNS (Domain Name Server). The method comprises the following steps: A, a source end host transmits a DNS inquiry message which carries a domain name of a destination end host to the DNS, and the DNS returns a DNS response message which comprises an AID of the destination end host to the source end host; B, an access service node (ASN) intercepts a DNS response message to acquire the AID of the destination end host in the response message; C, an ASN (Access Service End) inquires a route ID (RID) of the destination end host from a mapping server according to the AID of the destination end host; and D, the ASN receives a data message sent by the source end host to the destination end host and forwards the data message according to the RID of the destination end host. According to the method, the service access node and the system, the data message forwarding efficiency can be increased.

Description

technical field [0001] The invention relates to the field of communication, in particular to a processing method, system and access service node for data messages in an identity-location separation network. Background technique [0002] 3G and 4G are the core of next-generation network research in the field of wireless communication, aiming to improve the quality of wireless mobile communication based on the all-IP packet core network; NGN and NGI are the research on the integration of next-generation In the construction of the IPv6-based next-generation Internet; although there are great differences among various studies, the generally accepted view of various studies is that the future network is a unified bearer network based on packets. Therefore, the study of next-generation network architecture will take the Internet as the main reference object. The Internet has maintained rapid development since its birth, and has become the most successful and vital communication n...

In this way, the two attributes of the IP address conflict, which eventually leads to the scalability problem of the Internet routing system.

[0022] In this case, ASNs receives the data message sent by the terminal to the peer, initiates a query of the mapping information of the peer, and waits for the mapping server to return the mapping information of the peer. ASNs must cache the received data message, consuming a lot of resources , the longer the waiting time, the larger the amount of cached data, which will inevitably affect the normal forwarding performance; at the same time, there are hidden dangers in security, and it is easy to form an attack on the mapping server
