SYSTEM

AND

METHOD

FOR

LOCATING,

IDENTIFYING

AND

PROVISIONING

NEWLY

DEPLOYED

NETWORK

DEVICES

FIELD

OF

THE

INVENTION

This

invention

relates

to

communications

systems,

and

more

particularly,

this

invention

relates

to locating,

identify

ing

and

provisioning

newly

deployed

network

devices.

BACKGROUND

OF

THE

INVENTION

Service

providers

such

as

telecommunications

companies

will

deploy

new

network

equipment

as

network

devices.

The

service

providers

generally

will

manually

provision

several

items

such

as

an

IP

address,

default

gateway,

management

VLAN,

device

name,

and

device

location

before

the

new

network

equipment can

be

seen

or

managed

by

a

remote

network

manager,

for

example,

a

Network

Management

Sys

tem

(N

MS),

also

referred

to

often

as

a

Network

Management

Administrator

(NMA)

by

some

skilled

in

the

art.

An

example

of

a

NMS

is

a

management

system

as

manufactured

and

supplied

by

ADTRAN,

INC.

of

Huntsville,

Ala.

This

process

is

time

consuming

and

error

prone

and

requires

operators

to

spend

large

amounts

of time

at

remote

sites.

Also,

if

any

information

used

for

provisioning

is

not

set

correctly,

it

may

require

additional

trips

such

as

“truck

rolls”

to

remote

sites

to

correct

it.

A

newly

deployed

network

device,

also

referred

to

as

a

network

element,

can

announce

itself

to

the

network

manager

using

a

different

number

of

techniques

once

it

is

connected

into

the

communications

network.

If

no

information

or

data

has

been

provisioned

into

the

newly

deployed

network

device,

however,

the

network

manager

acting

as

a

network

administrator

has

no

way

to

know

the location

of

the

newly

deployed

device,

and

thus,

the

network

manager

does

not

know

the

identity

of

the

newly

deployed

device

using

existing

mechanisms.

SUMMARY

OF

THE

INVENTION

A

plurality

of

network

switches

as

network

elements

are

interconnected

together

and con?gured

to

form

a

communi

cations

network.

At

least

one

existing

neighboring

network

device

is

connected

to

a

newly

deployed

network

device

on

the

communications

network.

A

network

manager

is

con

nected

remotely

in

the

network

from

the

newly

deployed

network

device

and

an

existing

neighboring

network

device.

The

newly

deployed

network

device

is

con?gured

to

deter

mine

its

physical

network

connectivity

within

the

communi

cations

network

by

propagating

a

discovery

protocol

frame

to

the

at

least

one

existing

neighboring

network

device.

This

discovery

protocol

frame

in

one

example

is

a

?eld

having

a

query

that

solicits

from

the

existing

neighboring

network

device

the

physical

network

connectivity

data

of

the

newly

deployed

device.

This device

is

also

con?gured

to

receive

in

response

to

the

query,

its

physical

network

connectivity

data

and

network

data

address

of

the

network

manager

in

a

response,

transmit

its

physical

network

connectivity

data

to

the

remote

network

manager,

which

in

turn

is

con?gured

to

transmit

provisioning

data

to

the

newly

deployed

network

device

based

on

the

received

physical

network

connectivity

data.

In

one

example,

the

physical

network

connectivity data

comprises

at

least

one

network

data

address

for

the

network

manager.

The

newly

deployed

network

device

is

con?gured

to

receive

a

plurality

of

potential

network

data

addresses

for

20

the

network

manager

and

attempt

connection

to

the

network

manager

using

at

least

one

of

the

plurality

of

potential

net

work

data

addresses.

In the

event

the

newly

deployed

network

device

does

not

receive

a

network

data

address

for

the net

work

manager,

the

newly

deployed

device

is

con?gured

to

announce

itself

by

transmitting

layer

2

broadcast

messages

throughout

the

communications

network.

In

another

example,

the

discovery

protocol

frame

com

prises

a

Link

Layer

Discovery

Protocol

(LLDP)

frame

and

in

yet

another

example,

it

comprises

a

link

layer

Ethernet

OAM

message.

The

physical

network

connectivity

data

in

another

example

comprises

at

least

one

of

the

physical

and

logical

location

connection

data

for

the

newly

deployed

network

device

and

data

uniquely

identifying

the

existing

connected

device.

At

least

one

of

the

physical

and

logical

location

con

nection

data

comprises

data

regarding

the

physical

slot

and

port

of

the

existing

neighboring

device.

In

another

example,

the

at

least

one

of

the

physical

and

logical

location

connection

data

comprises

data

regarding

the

ID

of

a

logical

Ethernet

in

the

First

Mile

(EFM)

bonding

group.

In

another

example,

the

physical

network

connectivity

data

comprises

device

data

that

identi?es

the

existing

network

device.

This device

data

could

be

at

least

one

of an

IP

address

and

node

number

of

the

existing

neighboring

network

device

to

the

newly

deployed

network

device.

A

Management

Infor

mation

Base

(MIB)

is

con?gured

to

be

accessed

via

the

Simple

Network

Management

Protocol

(SNMP)

to

determine

the

physical

network

connectivity

data.

It

is

also

possible

that

the

at

least

one

existing

neighboring

network

device

is

con?gured

to

determine

the

physical

net

work

connectivity

of

the

newly

deployed

network

device

and

propagate

a

discovery

protocol

frame

that

comprises

a

?eld

having

a

query

that

solicits

the

physical

network

connectivity

of

the

newly

deployed

network

device

within

the

communi

cations

network.

The

network

connectivity

data

is

transmitted

to

the

network

manager,

which

then

transmits

provisioning

data

to

the

newly

deployed

network

device

based

on

the

received

physical

network

connectivity

data.

Thus,

while

the

newly

deployed

device

could

send

a

query

over

LLDP

as

previously

described,

this

embodiment

may

have

the

existing

device

sending

the

required

location

and

addressing

informa

tion

within

LLDP

TLV’s

all

the

time

without

requiring

the

new

device

to

send

the

query.

A

method

aspect

is

also

set

forth.
