Abstract

The present invention discloses a connection establishing method and apparatus applied to server load balancing. The method comprises the steps of a load balancing server receives a synchronization message sent by a client, calculating a sequence value according to the client connection information in a synchronization message, replying a synchronization confirmation message write-in real server connection information to the client, and taking the sequence value as the serial number in the synchronization confirmation message, receiving the confirmation message replied by the client, calculating the client connection information according to a confirmation number in the confirmation message, constructing a customized message write-in the client connection information, sending the customized message to a real server so that the real server can resolve the client connection information from the customized message, and establishing connection with client transmission control protocol (TCP) according to the client connection information. Resource consumption in a connection establishment process is reduced and attacking from an attacker can be effectively prevented.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular, relates to a connection establishment method and device applied in server load balancing. Background technique [0002] Server load balancing refers to the technology that the load balancing server balances the client's access traffic to multiple back-end real servers to achieve the load balancing effect on the real servers. [0003] When performing load balancing, due to the addition of a load balancing server, the request message sent by the client needs to be forwarded to the real server through the load balancing server. Therefore, the process of message processing has also changed. In an existing server load balancing mode, the packet processing process is that the client sends the request packet to the load balancing server, and then the load balancing server forwards the client request packet to the called real server, and then the real server Reply the ...
