Flow control method based on single connection and multiple requests

Abstract

The invention provides a flow control method based on single connection and multiple requests, comprising the following steps: S1, a server receives requests initiated by a client, and forwards the requests to a source server; S2, after receiving a response sent back by the source server, the server segments the response into frames and puts the frames in response chain tables of the requests in a to-be-sent data set; S3, the server detects whether the connection with the client is writable, and the method goes to S4 if the connection with the client is writable; S4, the size of the sending window of each request is adjusted according to the size of to-be-sent data in a system buffer area; and S5, data is acquired from the to-be-sent data set and sent to the system buffer area, and the method goes back to S3. According to the flow control method based on single connection and multiple requests of the invention, the TCP mechanism of the system is utilized, the size of the window of each current request is calculated in real time at the server, and the real-time performance of flow control is improved; and there is no need for the client to send a window change notice, and the uplink overhead is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a flow control method based on single connection multiple requests in the mobile Internet. Background technique [0002] Since it takes a certain amount of time to establish a connection between the client and the server and the number of handles that the server allows to be opened at the same time is limited, and in order to speed up the connection and reduce the overhead of the server, more and more connections between the client and the server The communication adopts a communication model that carries multiple requests on a long connection. But when multiple requests are concurrent, there is also a competition problem between each request. [0003] Currently, there are two main protocols based on this communication model: [0004] (1) pipeline agreement [0005] Httppipeline is a technology that implements multiple http requests and writes to the same socket without w...

However, for mobile communication networks, low bandwidth and high latency are the characteristics. The size of this buffer will make flow control unfair, and it is easy to cause large requests to block small requests.
