Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a data transmission method and system to solve the problem that the messages sent by the terminal are out of sequence due to different message forwarding paths before and after the ASN saves the mapping information of the terminal’s identity and location. , so that the destination terminal can obtain the messages arranged according to the sending order of the source terminal

Embodiment Construction

[0029] figure 1 Shown is a network architecture that realizes the separation of identity identifiers and location identifiers. This architecture divides the network into an access network and a backbone network. The access network is located at the edge of the backbone network and is responsible for the access of all terminals. The backbone network is responsible for the routing and forwarding of data packets between terminals accessed through the access network. There is no overlap between the access network and the backbone network in topology.

[0030] There are two types of identifiers in the network of this architecture: Access Identifier (AID: Access Identifier) ​​and Routing Identifier (RID: Routing Identifier). Among them, AID is the user identity identification of the terminal, which is used to identify the identity of the terminal user (also referred to as the user for short). The network uniquely assigns an AID to each terminal user. Change; RID is a location ide...

Abstract

The invention discloses a data transmission method, which is applied in network with separated identity identification and positioning identification. The data transmission method comprises the following steps: a source access support node (ASN) receives a source data packet sent by a source terminal, then adds an extension header for the source data packet so as to package the source data packet into an extension data packet; a field is set in the extension data packet to record the sequence number of the source data packet; and the source ASN sends the extension data packet to a destination ASN by a backbone network. In the invention, the source ASN packages sequence number information in a generic routing encapsulation (GRE) header so as to show a time sequence of the data packet received by the destination ASN; and the destination ASN can judge whether a disordered sequence occurs on a transmission path according to the sequence number, if so, the destination ASN can perfrom sequencing processing according to the increasing characteristic of the sequence number, eliminate the disordered sequence occurring on the transmission path and guarantee that the sequence of messages sent to a destination terminal is consistent to that of messages of the source terminal, therefore, the transmission quality is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data transmission method and system. Background technique [0002] At present, the IP address in the TCP / IP (Transmission Control Protocol / Internet Internet Protocol) protocol widely used on the Internet has dual functions. The identity of the interface. At the beginning of the TCP / IP protocol design, the movement of the host was not considered. However, when the host mobile becomes more and more common, the semantic overload defect of this IP address becomes more and more obvious. When the IP address of the host changes, not only the route will change, but also the identity of the communication terminal host will change, which will lead to an increasingly heavy routing load, and the change of the host identity will lead to interruption of applications and connections. [0003] The purpose of proposing the separation of identity identification and location identificatio...
