TCP service device and method

Abstract

The invention relates to the technical field of TCP service, and discloses a TCP service device and a method. The device comprises a receiving unit, a manage progress unit and at least one work progress unit, wherein, the receiving unit is used for receiving a connection request initiated by a client, and putting the connection request into a kernel queue; the manage progress unit is used for checking the kernel queue, and distributing and processing the task of the connection request for the work progress unit after an unprocessed connection request is checked to be contained in the kernel queue, and updating the connection number of the work progress unit when receiving the notification sent after the work progress unit finishes the task; and the work progress unit is used for processing the task distributed by the manage progress unit and sending notification to the manage progress unit after finishing the task. By the invention, the processing efficiency of the TCP service can be improved, and the effective management of the TCP service can be realized.

Description

technical field [0001] The present invention relates to a TCP (Transmission Control Protocol, transmission control protocol) service technology, in particular to a TCP service device and method. Background technique [0002] TCP is a connection-oriented, reliable, and byte-stream-based transport layer communication protocol. In the simplified computer network OSI (Open System Interconnect, Open System Interconnect) model, it completes the fourth layer, which is the specified transport layer. function, UDP (User Datagram Protocol, User Datagram Protocol) is another important transport protocol in the same layer. [0003] In the Internet protocol suite, the TCP layer is an intermediate layer located above the IP layer and below the application layer. Reliable, pipe-like connections are often required between application layers of different hosts, but the IP layer does not provide such a flow mechanism, but provides unreliable packet switching. After the TCP connection is est...

AI Technical Summary

Problems solved by technology

[0007] 1. The parent process generates a socket after receiving the connection request, and transfers the socket through sendmsg / recvmsg, and the processing efficiency is low;

[0008] 2. When the sub-processes have been assigned tasks and all of them are in the "busy" state, new tasks cannot be assigned. In a situation similar to a web server, when there is a connection but no interaction on the connection (that is, the connection is idle), The program cannot handle
