It

Will

be

appreciated

that

the

embodiment

dis

closed

in

FIG.

5

is

of

great

advantage

as

it

enables

the

application

to

access

the

Internet

Without

requiring

a

physi

cal

X25

network

interface.

Furthermore,

it

Will

be

appre

ciated

that

the

X25

virtual

netWork

interface

card

112

and

the

encapsulating/decapsulating

unit

114

may

be

installed

at

once

or

When

desired.

[0063]

While

illustrated

in

the

block

diagrams

as

groups

of

discrete

components

communicating

With

each

other

via

distinct

data

signal

connections,

it

Will

be

understood

by

those

skilled

in

the

art

that

the

preferred

embodiments

are

provided

by

a

combination of

hardWare

and

softWare

com

ponents,

With

some

components

being

implemented

by

a

given

function

or

operation

of

a

hardWare

or

softWare

system,

and

many

of

the

data

paths

illustrated

being

imple

mented by

data

communication

Within

a

computer

applica

tion

or

operating

system.

The

structure

illustrated

is

thus

provided

for

ef?ciency

of

teaching

the

present

preferred

embodiment.

[0064]

It

should

be

noted

that

the

present

invention

can

be

carried

out

as

a

method, can

be

embodied

in

a

system,

a

computer

readable

medium

or

an

electrical

or

electro-mag

netic

signal.

[0065]

The

embodiments

of

the

invention

described

above

are

intended

to

be

exemplary

only.

The

scope

of

the

inven

tion

is

therefore

intended

to

be

limited

solely

by

the

scope

of

the

appended

claims.

We

claim:

1.

A

method

for

enabling

an

application

that

uses

a

?rst

communication

protocol

to

communicate

With

a

physical

netWork

interface

that

uses

a

second

communication

proto

col,

said

method

comprising:

providing

a

driver

for

simulating

another

netWork

inter

face

communicating

With

said

?rst

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

Jun.

8,

2006

if

said

data

packet

is

received

from

said

netWork

interface,

decapsulating

said

data

packet

to

provide

a

data

packet

suitable

With

said

?rst

communication

protocol

and

providing

said

decapsulated

data

packet

to

said

appli

cation

using

said

driver.

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

lntemet.

6.

from

at

least

one

of

a

remote

location

and

a

local

location.

7.

A

driver

for

enabling

an

application

that

uses

a

?rst

communication

protocol
