Abstract
A system and method are disclosed for redirecting a connection from a first server having a first server IP address. Incoming SYN packets sent from a client are intercepted. The SYN packets have a destination IP address corresponding to the connection and the SYN packets are sent from the client for the purpose of establishing the connection, which is supported by the first server. The number of incoming SYN packets sent from the client to the first server is monitored and it is determined whether the number of unanswered SYN packets sent by the client to the first server exceeds a ditched connection threshold number of unanswered SYN packets. The destination IP address of intercepted incoming SYN packets is changed for the connection received after determining that the number of unanswered SYN requests sent by the client to the first server exceeds a ditched connection threshold number of unanswered SYN requests to the destination IP address of a second server. In this manner, the SYN packets sent from the client for the purpose of establishing the connection are sent to the second server so that the connection is established with the second server.
