Abstract: A system, method and computer program product for communicating with a private network are described. An application of a client is monitored for communications intended for a node coupled to a private network. A communication from the monitored application of the client that is intended for the node may then be intercepted before the communication can be received by the transport layer of the client, the intercepted communication may then be sent with a connection identifier to an interface unit coupled to the private network via an established network connection over a public network. The connection identifier also associated with a communication link that is established over the private network between the interface unit and the node. The interface unit uses the connection identifier that is received with the communication to identify the associated communication link over the private network.

Abstract: A method for maximizing server throughput while avoiding overload of a server is presented. The method involves intercepting, via an interface unit, a client request for information from the server. Next, the interface unit determines the current server performance, where the server performance is based on the number of connections opened to the server, the response time of the server and the rate at which the response time is changing. Finally, the interface unit forwards the client request to the server if the current server performance is close to an optimal performance, whereby avoiding overload of the server.
