Problems solved by technology

When communicating, the communication peer selects the preferred address declared by the multi-home host as the communication address. When the address is unreachable or the multi-home host declares another preferred address, the communication peer updates the currently used address of the multi-home host to another One, that realizes connection-oriented mobility management, but the current HIP protocol cannot realize data flow-oriented mobility management

Embodiment 1

[0042] figure 2 A flowchart of the data stream transmission method provided in Embodiment 1 of the present invention, including:

[0043] In step S201, the multiple home hosts determine the data stream requested to be redirected, that is, after the redirected data stream is redirected, the multiple home hosts will be used compared to the original addresses of the multiple home hosts used to transmit the data stream. The update address transmits the data stream; in this step, the update addresses of the multiple home hosts that transmit the data stream requested to be redirected are also determined correspondingly.

[0044] Specifically, the data stream for which redirection is requested can be determined by considering changes in the available addresses of multiple home hosts, the transmission characteristics of the addresses when transmitting data streams, and the load balancing among the data transmission volumes of multiple addresses. Correspondingly used update addresses...

Embodiment 2

[0071] Based on the same inventive concept, according to the data stream transmission method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 2 of the present invention also provides a multi-homed host, the schematic diagram of which is as follows: Figure 4 shown, including:

[0072] Determining unit 401, configured to determine the data stream for which redirection is requested, and the update address of the local host used for transmitting the data stream;

[0073] The transmission unit 402 is used to send an address update message to the communication peer corresponding to the data stream, and the address update message carries the corresponding relationship between the stream identifier of the data stream and the update address; and after receiving the address returned by the communication peer After the update is successfully responded, the data stream is transmitted with the communication peer through the update address. ...

Embodiment 3

[0081] Based on the same inventive concept, according to the data stream transmission method provided by the foregoing embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides a multi-homed host, the schematic diagram of which is as follows: Figure 5 shown, including:

[0082] The transmission unit 501 is used to receive the address update message sent by the communication peer, the address update message carries the flow identifier of the data stream and the corresponding relationship of the update address of the communication peer used for transmitting the data stream; and returns the address to the communication peer After the update is successfully responded, transmit the data stream with the communication peer through the update address;

[0083] The updating unit 502 is configured to use the updating address to update the original address of the communication peer used for transmitting the data stream based on the corres...

Abstract

The invention discloses a data stream transmission method, a data stream transmission device and a data stream transmission system. The data stream transmission method includes the steps: firstly, identifying a multi-homing host in a network, determining data stream requesting redirection and transmitting a updated address of the multi-homing host used by the data stream; secondly, sending updated address information to a correspondent node corresponding to the data stream, wherein the updated address information carries a corresponding relation of a stream identifier of the data stream to the updated address; and thirdly, transmitting the data stream by the aid of the updated address and the correspondent node after successful response returned by the correspondent node to address updating is received. By the aid of the method, mobile management facing the data stream in the identification network can be realized.

Description

technical field [0001] The present invention relates to the technical field of data stream transmission in the communication field, and in particular, to a data stream transmission method, device and system. Background technique [0002] In the Transmission Control Protocol / Internet Protocol (TCP / IP) system of the traditional Internet, the IP address not only represents the location identifier of the node, but also represents the host identifier of the node. The network layer uses the IP address as the node in the network. The location identifier is used for routing, and the transport layer uses the IP address as the host identifier of the node to establish the connection of the transport layer. When a node changes its IP address due to movement, the transport layer connection is interrupted and the connection needs to be re-established. Therefore, the TCP / IP protocol system of the traditional Internet is not conducive to supporting the session continuity of the mobile node...
