DEVICE AND METHOD FOR ESTABLISHING CONNECTION IN LOAD-BALANCING SYSTEM

摘要

An apparatus for establishing a connection in a load-balancing system is provided. The apparatus is coupled between a client device and a real server that provides services to the client device. The apparatus includes: a memory device storing instructions; and a processor configured to execute the instructions stored in the memory device to: receive a synchronous (SYN) packet from the client device, the SYN packet including client connection information; based on the client connection information, compute a serial number; return a first synchronous acknowledgement (SYN+ACK) packet to the client device, the first SYN+ACK packet including connection information of the real server; receive an acknowledgement (ACK) packet from the client; generate a self-defined packet to include the client connection information; and forward the self-defined packet to the real server
