Method and device for establishing high-performance network long connection

Abstract

The invention provides a method and device for establishing high-performance network long connection, relates to the fields of communication and finance, and the method comprises the following steps: establishing a long connection with a client according to a long connection establishment request of the client; selecting a corresponding tracker from pre-created trackers according to the type of the client, and monitoring the state of the long connection by using the selected tracker; wherein the states comprise creation, disconnection and operation; and sending a message corresponding to the state to the client by using a pre-constructed splitter. According to the invention, an open universal high-performance network long connection engine can be provided, so that high-availability long connection service can be quickly constructed.

Description

technical field [0001] This application relates to the communication field, can be used in the financial field, and is specifically a method and device for establishing a high-performance network long connection. Background technique [0002] In instant messaging, data monitoring and other fields where clients need to share server data in real time, timed polling and long connection are two commonly used technical solutions. Due to timed polling, there are disadvantages such as high data sharing delay and high client resource consumption. , the technical solution of long connection is more favored by developers. The existing long connection technology based on Java language is realized by Websocket protocol, which provides a basic long connection service endpoint life cycle management API. The creation, use and destruction of persistent connection service endpoints, together with the encapsulation of the client, can support the conventional data sharing requirements between ...

AI Technical Summary

Problems solved by technology

[0003] 1) Unable to uniformly manage service endpoints

[0004] Existing technologies only provide the ability to create, use, and recycle a single connection, and cannot directly realize unified viewing and scheduling of all online connections

[0005] 2) Message delay and loss problems are obvious in high concurrency scenarios

[0006] Existing technologies are implemented based on a synchronization mechanism. There is no message buffering mechanism. In high-concurrency scenarios, messages may be delayed, blocked, or even lost.

[0007] 3) A single application cannot support multiple scenarios

[0008] Existing technologies can only implement a set of logic for important nodes such as connection creation and message processing, and cannot support the coexistence of multiple long-term connection services

[0009] 4) Incompatible with multiple abnormal situations

Once the above situation occurs, the memory of the server may be idle, causing the system to crash
