Problems solved by technology

[0007] Therefore, in a harsh network environment, MPTCP only uses the network quality characterization parameters of the TCP layer (such as: RTT, packet loss rate, delivery rate, etc.), and cannot quickly adapt to changes in the network environment, resulting in the inability to quickly establish subflows. Complete the handshake and always transmit data on the poor quality substream
Due to the inability to capture the changes in sub-flow network quality in time, the packet disorder caused by the network differences of each sub-flow will be more serious. MPTCP's existing path manager and packet scheduler cannot solve these problems well.

Embodiment Construction

[0070] Specifically, the present invention provides a cross-layer path management and data packet scheduling cross-layer optimization method for MPTCP of a multi-cellular wireless access gateway. In one embodiment of the present invention, the cross-layer optimization system includes the following steps :

[0071] Step 1: Obtain the physical layer characterization parameters through the multi-thread pipeline, process the physical layer characterization parameters, and transmit the processed parameters to the MPTCP path manager and the packet scheduler respectively; technical effect: each thread obtains each time The operation time until the physical layer characterization parameters is less than 0.1ms, and the newly acquired parameters will directly cover the historical physical parameters.

[0072] Step 2: Use the processed physical layer characterization parameters, combined with the transport layer characterization parameters, to guide the MPTCP path manager to establish su...

Abstract

The present invention relates to an MPTCP cross-layer optimization method based on a multi-cellular wireless access gateway, which is characterized in that it includes: a data processing step, obtaining a first parameter group of the cellular wireless network, and processing the first parameter group to obtain A second parameter group, and transmit the second parameter group to the MPTCP path manager and the data packet scheduler respectively; the sub-flow creation step, the path manager measures and calculates one of the cellular wireless networks according to the second parameter group A third parameter, and using the third parameter in combination with the second parameter group to establish a sub-flow; a data allocation step, according to the second parameter group and the third parameter, the data packet scheduler allocates data to the sub-flow .

Description

technical field [0001] The present invention relates to the field of computer network transmission control, in particular, the present invention relates to a multipath transmission control protocol (Multipath Transmission Control Protocol: MPTCP) cross-layer optimization method and system for multi-cellular wireless access. Background technique [0002] At present, many communication devices have multiple network homed interfaces (Multi-homed) for users to transmit data. These network interfaces can access and use access networks implemented at different physical layers (for example: wired, WiFi, cellular radio base stations). Wherein, the cellular wireless base station includes various cellular wireless (cellular) access networks provided by different service providers (for example: China Mobile, China Unicom, China Telecom). Usually, the data delivered to different network interfaces does not overlap on the routing path. The traditional Transmission Control Protocol (TCP...
