Abstract:
1. A method for managing a data transmission in a network, the network having a client, a load balancing node and a server cluster, the method comprising the steps of: monitoring a port on the load balancing node, the port using a security protocol; receiving a client connection, the connection being based on the security protocol, and having TCP/IP information of the client; establishing handshake between the client and the load balancing node based on the security protocol, the handshake resulting in session information and working keys; selecting a real server from the server cluster by the load balancing node based on a load balancing policy; exporting a context to the real server, the context comprising the TCP/IP information of the client, the session information, and the working keys; extending a logical end point of the client connection from the load balancing node to the real server to form a real server connection; splicing the client connection and the real server connection to relay a traffic, the traffic being encrypted using the security protocol, between the client and the real server; and establishing a direct communication between the client end the real server for subsequent connections having the context.
