Problems solved by technology

[0030] The present invention provides a flow state establishment and data transmission method and system in an IPv6 network environment, which is used to solve the problems in the above-mentioned prior art that all data packets belonging to the same flow must carry the same hop-by-hop The effective payload reduction caused by the extension header or routing header and the problem that the flow state cannot be deleted in a timely and effective manner, so as to establish an end-to-end connection that can support QoS, manage and maintain in IPv6

Embodiment Construction

[0064] The core of the present invention is: a source node sends a message requesting to establish / delete a flow transmission path to a destination node, and the intermediate node establishes / deletes a flow state according to the information of the intermediate node after receiving the message; when the destination node receives the message , to establish / delete an end-to-end flow transmission path between the source node and the destination node of the flow.

[0065] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0066] The flow chart of the establishment method of the flow state provided by the present invention is shown in Figure 4, comprising the following steps:

[0067] Step 401: The source node of the stream sends a message for establishing a stream transmission path;

[0068] First, you need to configure the flow transmission path between the source node and the destination ...

Abstract

A method for setting up flow transmission path in IPv6 network environment includes sending message for requesting to set-up / delete flow transmission to destination node by source node, setting up / deleting flow state according to intermediate node information when said message is received by intermediate node, setting up / deleting end to end flow transmission path between flow source node and destination node for setting up end to end connection in IPv6 when said message is received by destination node.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for establishing a stream transmission path in an IPv6 network environment and a data transmission system. Background technique [0002] With the development of Internet technology, driving factors such as the exhaustion of IPv4 address resources and the massive demand for network address resources from mobile and broadband are driving the evolution of the current IPv4 network to the next-generation Internet protocol IPv6 network. Compared with IPv4, the changes of IPv6 are reflected in the following five important aspects: [0003] 1. Extended address [0004] 2. Simplified header format [0005] 3. Enhanced support for extensions and options [0006] 4. Stream label [0007] 5. Identity verification and confidentiality [0008] In addition to solving the address shortage problem of IPv4, these changes of IPv6 also have the following advantages: expanding the a...
