Protocol.

A

proprietary

terminal

control

protocol

owned

and

defined

by

Cisco
as
a

messaging

set

between

a

skinny

client

and

the

Cisco

CallManager

(CCM ).

Examples

of

skinny
clients
include

the

Cisco

7900

series

of

IP

phone

such

as

the

Cisco

SLB
Server
Load

Balancer.

A

device

that

makes

load

balancing

decisions

based

on
application

availability,
server
capacity,

and

load

distribution

algorithms,

such

as

round

robin

or

least

connections.

Using

load
balancing
and

server/application

feedback,

an

SLB

device

determines

a

real

server

for

the

packet

flow
and
sends

this

information

to

the

requesting

forwarding

agent.

After

the

optimal

destination

is

decided
on,
all

other

packets

in

the

packet

flow

are

directed

to

a

real

server

by

the

forwarding

agent,

SMTP
Simple

Transfer

Protocol.

Internet

protocol

that

sticky
A
feature

that

ensures

that

the

same
client
gets

the
same
server

for

multiple
connections.
It

is

used

when
applications
require

a

consistent

and

constant

connection

to

the

same

server.

If

you

are

connecting

to
a
system

that

keeps

state

tables

about

your

connection,

sticky

allows

you

to

get

back

to

the

same

real
server
again

and

retain

the

statefulness

of

the

system.

Removes
an

entity

from

for

requests

Suspending
a

device

does

not


affect

flows,

from
