Transmission control protocol (TCP) long-connection access control method and device

Abstract

The invention discloses a transmission control protocol (TCP) long-connection access control method comprising the following steps: receiving synchronous notification messages comprising TCP long-connection access or disconnection information sent by a long-connection front-end processor via a central control node; calculating the number of the current TCP long connections; receiving a TCP long-connection application request message sent by the long-connection front-end processor; judging whether the number of the current TCP long connections is less than a preset value; if yes, returning an application response message permitted to access to the long-connection front-end processor; and otherwise, returning an application response message which is not permitted to access to the long-connection front-end processor. The invention also provides the corresponding central control node, the long-connection front-end processor and telecommunication equipment. In the technical scheme, the central control node judges whether the number of the current TCP long connections is less than a preset value so as to decide whether a TCP long connection is permitted to access; the number of the accessed TCP long connections can be accurately calculated and controlled; and thus, the telecommunication equipment can reliably operate.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a transmission control protocol TCP persistent connection access control method and device. Background technique [0002] The Transmission Control Protocol (TCP) persistent connection is a connection mode in which a communication connection is established first, and the connection is not disconnected after the connection is established, and then the message can be sent and received repeatedly. It is often used in point-to-point communication. [0003] With the rapid increase of telecommunication data traffic, telecommunication devices carrying data services, such as gateway devices, usually access a large number of long TCP connections established by external customers. On the one hand, telecommunications equipment needs to ensure the establishment of TCP long-term connections of external network elements as much as possible to meet the development of data services;...

AI Technical Summary

Problems solved by technology

As a cluster system including multiple long-connection front-ends, this kind of telecommunication equipment improves the ability to access TCP long-term connections; however, since each long-connection front-end is independent of each other, it cannot coordinately control the incoming TCP long-connections
