Method for reducing data, apparatus and computer program product for making the same

摘要

The invented method, apparatus and computer program product include establishing a first virtual socket in the first computer (5) in response to each connection request by the first application for receiving request data originated by the first application. A first real socket in the first computer (5) and a second real socket in the second computer (6) are established to connect the first computer (5) to the second computer (6) over the external communication link (35) and are maintained until the request data has been provided to the second application. In the second computer (6) a second virtual socket is established for each connection request by the first application wherein the second virtual socket corresponds to a first virtual socket established in the first computer (5) in response to a connection request by the first application. Request data associated with a first virtual socket is multiplexed onto the first real socket and transmitted over the external communication link (35) utilizing the Transfer Control Protocol. The multiplexed request data is received from the external communication link (35) by the second real socket. Further the multiplexed request data received from the external communication link (35) by the second real socket are demultiplexed. The demultiplexed request data is provided to the corresponding second virtual socket, which provides the request data to the second application. The first and the second real sockets are maintained until the request data corresponding to a request from the first application which established the first virtual socket has been provided to the second application.
