TCP message load balancing method and device

The invention discloses a TCP message load balancing method and device. The method comprises the steps: determining an application type corresponding to a TCP message from a terminal; determining a first exit corresponding to the TCP message according to a first corresponding relationship between the application type and the hash factor and the determined application type; determining whether TCPflow information to which the TCP message belongs exists in a TCP flow information table or not; if the TCP message does not exist, establishing TCP flow information, storing the TCP message, and performing TCP proxy forwarding on the TCP message through a first outlet; if so, determining whether the first outlet is the same as a second outlet included in the TCP flow information: if so, performing TCP proxy forwarding on the TCP message through the first outlet, and storing the TCP message when determining that the application type is a default type; if not, updating the second outlet to thefirst outlet, storing the
