COMMUNICATION MODULE AND APPLICATION PROGRAM PROVIDED WITH SAME
First Claim
1. A communication module installed in a client apparatus on a local network for connecting an application software program installed in said client apparatus to a virtual network via a server on the Internet,wherein the communication module interposes between said application software program and a group of local communication protocol stacks of an operating system installed in said client apparatus;
- retains a virtual network address for said application software program;
performs the tunneling processing on packets from said application software program to the virtual network to thereby pass the processed packets to said server through the local communication protocol stacks; and
wherein the communication module is provided with protocol stacks required for said application software program to communicate via the virtual network, independently of said group of local communication protocol stacks.

Abstract
Bidirectional communication is performed by an application employing particular communication protocols without depending on any specific network environment enabled by an OS and the like. There is provided a communication module installed in a client apparatus for connecting an application software program to a virtual network via a server on the Internet. This module interposes between the application software program in a computer and a group of local communication protocol stacks of an operating system installed in the computer; retains a virtual network address for the application software program; performs the tunneling processing on packets from the application software program to the virtual network to thereby pass the processed packets to the server through the local communication protocol stacks; and is provided with Layer 2, 3 and 4 protocol stacks that are independent of a group of local communication protocol stacks.
