Embodiment Construction

[0039] Such as image 3 As shown, the data transmission system in the embodiment of the present invention includes: an evolved network sending device 10 and an evolved network receiving device 20 .

[0040] The evolved network sending device 10 is connected to the evolved network receiving device 20, and is used to establish a flow control transmission protocol coupling with the evolved network receiving device 20 through its own port, and send the upper layer information together with the data to the evolved network during data transmission. Network receiving device 20 .

[0041] The evolved network receiving device 20 is connected to the evolved network sending device 10, and is used to establish a flow control transmission protocol coupling with the evolved network sending device 10 through its own port, and after receiving the upper layer information and data from the evolved network sending device 10, Determine the upper layer protocol stack according to the upper layer ...

Abstract

The invention discloses a method for data transmission, comprising the steps that: A. a progressed network sending device and a progressed network receiving device create flow control transmission protocol couplings by their own ports; B. the progressed network sending device sends the top layer information together with data to the progressed network receiving device; C. after receiving the top layer information and data, the progressed network receiving device decides the top layer protocol stack according to the top layer information. The invention solves the problem that flow control transmission protocol coupling occupies large resource in current technology. The invention also discloses a system and a device for data transmission.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a data transmission method, system and equipment. Background technique [0002] In the next-generation system architecture evolution / long-term evolution (System Architecture Evolution: SAE / Long Term Evolution: LTE) network, in order to better complete the routing addressing function and reduce message delay, the network layer in the traditional telecom network is removed , place the application layer directly on the transport layer Stream Control Transmission Protocol (SCTP), and use the Internet Protocol (IP) layer to complete the routing search in the Transmission Control Protocol / Internet Protocol (TCP / IP) network address function. [0003] There are SCTP endpoints at the SCTP layer, which are logical senders and receivers of SCTP data packets, and each SCTP endpoint is uniquely identified by a port number and a set of IP addresses. Currently, the IP network adopts...
