DETAILED

SPECIFICATION

OF

THE

PREFERRED

EMBODIMENTS

In

the

following

detailed

description

of

the

preferred

embodiments,

reference

is

made

to

the

accompanying

draw

ings

which

form

a

part

hereof,

and

in

which

is

shown

by

way

of

illustration

speci?c

embodiments

in

which

the

invention

may

be

practiced.

It

is

to

be understood

that

other

embodi

ments

may

be

utiliZed

and

structural

changes

may

be

made

without

departing

from

the

scope

of

the

present

invention.

For

the

purposes

of

this

speci?cation,

any

device

or

system

associated

with

the

network

is

a

“resource”

of

the

network.

Physical

layers

or

platforms,

such

as

ethernet,

include

the

physical

portion

of

the

network.

Network

pro

tocols

include,

but

are

not

limited

to:

Transmission

Control

Protocol/Internet

(TCP/IP),

Hyptertext

Transfer

Protocol

(HTTP),

File

Transfer

Protocol

(FTP),

proprietary

resource

management

protocols,

Telnet,

and

Simple

Network

Man

agement

Protocol

(SNMP).

Network

languages

include,

but

are

not

limited

to:

Hypertext

Markup

Language

(HTML),

Java,

and

Virtual

Reality

Modeling

Language

(VRML).

Network

Resource

Management

System

FIG.

1

shows

a

block

diagram

of

a

prior

art

system

using

the

Simpli?ed

Network

Management

Protocol

(SNMP)

sys

tem

to

control

a

network

resource.

In

this

system,

the

client

must

provide

SNMP

instructions

for

controlling

the

network

resource.

The

client

is

required

to

run

a

special

program

for

SNMP

network

resource

management.

The

client

also

needs

to

learn

the

SNMP

protocol

to

perform

network

resource

management.

FIG.

2

shows

a

block

diagram

of

one

embodiment

of

the

present

network

resource

management

system,

whereby

a

number

of

existing

protocols

and

languages

are

available

for

the

system

to

manage

the

network

resource.

FIG.

2

shows

that

the

network

module

supports

several

existing

languages

which

are

compatible

with

the

Hypertext

Transfer

Protocol

(HTTP).

For example,

languages

which

may

be

used

include,

but

are

not

limited

to,

HTML,

Java,

and

VRML.

These

languages

may

be

used

independently

or

in

combi

nation

with

each

other

for

controlling

the

network

resource,

however,

other

protocols

and

languages

may

be

used

with

out

departing

from

the

scope

and

spirit

of

the

present

invention.

For

internet

network

resource

management,

any

TCP/IP

compatible

protocol

and

language

is

acceptable

for

network

resource

management.

The more

popular

the

protocol,

the

more

likely

users

will

have

a

compatible

browser

for

selecting

management

options

and

monitoring

resource

fault/status

conditions.

FIG.

shows

a

block

diagram

of

a

network

module,

as

generally

shown

in

FIG.

2.

The

network

module

400

con

tains

a

native

resource

instruction

library

410

which

is

a

compilation

of

the

native

resource

instructions

used

by

a

particular

network

resource.

Instruction

module

420

trans

lates

messages from

the

client,

received

over

the

network,

10

25

into

native

resource

instructions.

The

instruction

module

420

also

updates

an

options

database

430

after

a

message

has

been

translated.

The

options

database

430

is

a

menu

of

operations

which

the

client

may

select

from

to

manage

the

network

resource.

In

one

embodiment,

the

options

database

430

is

downloaded

to

the

client

upon

accessing

the

network

resource.

The

options

database

430

is

updated

as

operations

are

selected

by

the

client,

or

to

re?ect

status

of

the

network

resource.

The

updated

options

and/or

status

are

transmitted

to

the

client

by

the

network

module

400.

FIG.

5

shows

a

?owchart

of

a

network

resource

manage

ment

session.

The

client

accesses

the

particular

network

resource.

The

resource

responds

by

downloading

one

or

more

options

to

the

client

from

the

options

database

430

in

the

network

module

400.

The

options

are

preprogrammed

for

that

particular

network

resource,

and

each

option

is

associated

with an

operation

to

perform

at

the

network

resource.

The

options

may

identify

a

particular

operation

or

function

to

be

performed

for

managing

and/or

controlling

the

network

resource.

The

client

selects

an

option

and

the

client’s

browser

(or

web

page)

automatically

transmits

a

message

based

on

the

option

selected.

The

message

is

interpreted

by

the

instruction

module 420

by

comparing

the

message

with

the

native

resource

instruction

library

410

which

is

a

compilation

of

the

functions

and

operations

associated

with

the

network

resource.

In

one

embodiment

the

instruction

module

420

contains

logic

to

process

the

message

and

determine

whether

the

requested

function

or

operation

is

to

be

performed

by

the

network

resource.

The

network

resource

is

instructed

to

perform

authoriZed

opera

tions

or

functions.

The

options

database

430

is

updated

and

in

one

embodiment,

the

updated

options

are

transmitted

back

to

the

client

to

update

the

view

provided

the

client.

This

procedure

is

repeated

until

the

session

is

completed.

The

present

detailed

description

provides

several

examples

of

user

interfaces

which

may

be

implemented

using

a

number

of

different

programming

protocols

and

languages.

The

examples

are

intended

to

demonstrate

vari

ous

embodiments

of

the

present

invention

and

are

not

intended

in

a

limiting

or

exclusive

sense.

Other

protocols

and

languages

may

be

substituted

without

departing

from

the

scope

and

spirit

of

the

present

invention.

The

present

network

resource

management

system

is

available

for

incorporation

in

several

applications.

One

example

is

in

the

management

of

a

rack

of

modems,

as

described

in

the

following

sections.
