Session handling system and session handling method for long connection

Abstract

The invention provides a session handling system and session handling method for long connection. The session handling system comprises client sides, gateway servers and management servers. The long connection is built by the client sides and the gateway servers, and initial session information is generated. The session information received from the client sides is stored in the gateway servers, and messages from the client sides and the session information are forwarded to the management servers together. The management servers forward the messages from the client sides to service servers, and commands used for setting the session information are sent to the gateway servers when it is determined that the content of the session information needs to be executed. The gateway servers set the session information according to the received commands and store the set session information, and the stored set session information and the messages from the client sides are sent to the management servers together every time the messages from the client sides are forwarded.

Description

technical field [0001] The present invention relates to the technical field of the Internet, and more specifically, relates to a session processing method and a session processing system for persistent connections. Background technique [0002] In the field of Internet technology, a long connection usually means that multiple data packets can be sent continuously on one connection. During the connection maintenance period, if no data packets are sent, both parties need to send link detection packets. [0003] Session (session) is a persistent network protocol that creates an association between the user (or user agent) side and the server side, thereby exchanging data packets. Session is very important in network protocols (such as telnet or FTP). important part. In transport protocols that do not include a session layer (such as UDP) or cannot persist for a long time (such as HTTP), session maintenance relies on high-level procedures in the transmitted data. For example, ...

AI Technical Summary

Problems solved by technology

The disadvantages of this session mechanism may lie in:

[0006] 1. The security is low, and it is easy to be read and modified; 2. Since the session is placed on the connection, the session will be destroyed when the connection is disconnected; if the session is separated from the connection, the connection will be normal but the session will be lost unexpectedly Situations, such as a single point of compromise due to session store server downtime

If you want to design a session storage service, you need to consider scalability and many other factors, which greatly increases the complexity of the system; 3. If you use separate session storage, when the management server obtains the session, additional communication is required. In this way, in high concurrency In some cases, service performance will be affected, resulting in a decline in service robustness, for example, temporary data loss caused by session server downtime
