Problems solved by technology

[0017] First of all, when the identification value is 010, the hop-by-hop extension header in the IPv6 extension header has the function of indicating the meaning of QoS, where the last 17 bits in the flow label do not represent any meaning, resulting in a large waste of storage bits
[0018] Secondly, when the identification value is 101, among the QoS parameter types set in the last 17 bits of the flow label, the flow label only identifies the QoS requirements of the service flow, and does not play the role of identifying the flow, so that terminals and network elements cannot tags for flow identification and fast forwarding

Embodiment Construction

[0073] In order to improve the utilization rate of the flow label and realize effective data flow identification, in the embodiment of the present invention, a new technical definition and specification are made for the usage and semantics of the 20-bit flow label field in the next generation internet protocol header.

[0074] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0075] refer to image 3 As shown, in the embodiment of the present invention, the specific manner of transmitting the IPv6 data flow is as follows:

[0076] Step 300: Obtain a data stream to be sent.

[0077] Step 310: Carry out message encapsulation for the data stream to be sent, wherein, when encapsulating the message header, encapsulate the two bits of the flow label field in the message header as identification bits, and encapsulate the specified bits in the remaining bits of the flow label field Encapsulated as a stre...

Abstract

The invention relates to a wireless communication system, in particular to an IPv6 data stream transmission method and device. The method and device are used for improving the utilization rate of flow labels and achieving effective data stream identification. The method includes the steps that in the process that message packaging is carried out on a data stream, 20 bites in a flow label domain are divided in a new method, namely, two bites in the flow label domain are taken as identification bits, flow identification is carried out through specified bites in other bites in the flow label domain, the utilization rate of the bites in the flow label domain is improved, resource waste is avoided, the data stream can be effectively identified no matter which identification bit is used, other terminals and network elements receiving the data stream can accurately identify and quickly forward the data stream, and message processing efficiency of the system is improved.

Description

technical field [0001] The invention relates to a wireless communication system, in particular to a method and device for transmitting IPv6 data flow. Background technique [0002] It is an inevitable trend that the Long Term Evolution (LTE) system realizes the support of the next generation Internet Protocol (Internet Protocol Version 6, IPv6) at the IP layer. In order to support Quality of Service (QoS), IPv6 reserves a 20-bit flow label (Flow Label) field in the data header, and a flow label is combined with a source address to uniquely determine a data flow. Although flow labels are specially set by IPv6 to support quality of service, the usage and semantics of flow label QoS are not clearly defined in the IPv6 specification. How to use flow labels to better support quality of service in an LTE IPv6 network environment It is currently in the experimental stage. [0003] Currently, the representative scheme for using stream tags is Banerjee's draft. The Banerjee draft ...
