Problems solved by technology

[0005] When the MN communicates across the MA from the source network to the adjacent network, in order to maintain the continuity of communication with the CN, the oMA in the source network is required to process and route the communication data, thus increasing the oMA in the source network The burden of data processing increases the delay of data transmission and reduces the efficiency of data transmission

Abstract

The invention discloses a data transmission method. The method comprises the following steps: receiving a data packet from a mobile node, and acquiring the source IP address information and the destination IP address information of the data packet; according to the source IP address information and the destination IP address information, establishing a first SHIM6 associated tunnel used for transmitting the data packet with mobile agent equipment within an opposite terminal node home network; and carrying out data transmission between the mobile node and an opposite terminal node through the first SHIM6 associated tunnel. The embodiment of the invention also discloses network equipment and a data transmission system to optimize communication routing, shorten transmission delay, save network resources and reduce data forwarding and processing burden of mobile agent equipment of a source network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, system and network equipment. Background technique [0002] DMMS (Decentralized Mobility Management Service, decentralized mobility management service architecture) deploys mobility management equipment MA (Mobility Agent, mobile agent) at the edge of the network to provide mobility services for mobile nodes; MN (Mobile Node, mobile node) Location information is managed by D-DNS (Domain Name Server, Domain Name Server; Dynamic-DNS (Dynamic Domain Name Server)); CN (Corresponding Node, peer node) is the peer node that communicates with MN; oMA (old MA) It is a decentralized mobility management device used at the edge of the oAN (old AN access network) network; nMA is a decentralized mobility management device used at the edge of the nAN network. [0003] like figure 1 As shown, in order to ensure the continuity of communication with the CN when the M...
