Abstract

A method is disclosed for enabling an application communicating using a first communication protocol to communicate with a physical network interface communicating using a second communication protocol wherein a driver is installed for providing a virtual first communication protocol interface card.

Claims

1. A method for enabling an application that uses a first communication protocol to communicate with a physical network interface that uses a second communication protocol, said method comprising:

providing a driver for simulating another network interface communicating with said first communication protocol;

receiving a data packet from one of said application and said physical network interface;

if said data packet is received from said application, using the driver to encapsulate said data packet according to said second communication protocol and providing said encapsulated data packet to said physical network interface; and

if said data packet is received from said network interface, decapsulating said data packet to provide a data packet suitable with said first communication protocol and providing said decapsulated data packet to said application using said driver.

2. The method as claimed in claim 1, wherein said first communication protocol comprises X.25.

3. The method as claimed in claim 2, wherein said second communication protocol comprises TCP/IP.

4. The method as claimed in claim 3, further comprising providing said encapsulated packet via said physical network interface to at least one of a Wide Area Network (WAN), a Metropolitan Area Network (MAN) and a Local Area Network (LAN).

5. The method as claimed in claim 4, wherein said Wide Area Network comprises the Internet.

6. The method as claimed in claim 1, wherein said driver is provided from at least one of a remote location and a local location.

7. A driver for enabling an application that uses a first communication protocol to communicate with a physical network interface that uses a second communication protocol, said method comprising:

a software implemented network interface card simulating a network interface card for said application operating according to said first communication protocol; and

an encapsulating/decapsulating unit encapsulating a first given received packet from said software implemented network interface card according to said second communication protocol and providing said encapsulated packet to said physical network interface;

said encapsulating/decapsulating unit further decapsulating a second given received packet from said physical network interface according to said first communication protocol to provide a decapsulated packet and further providing said decapsulated packet to said application.

8. The driver as claimed in claim 7, wherein said first communication protocol comprises X.25.

9. The driver as claimed in claim 8, wherein said second communication protocol comprises TCP/IP.
