Urgent
Pointer

Policy
Action
that

the

ACE

takes

to

handle

urgent

data

as

identified

by

the

Urgent

data

control

bit.

Urgent
data,
as

indicated

by

a

control

bit

in

the

TCP

header,

indicates

that

urgent

data

is

to

be

processed

as
soon
as

possible,

even

before

nor

mal

data.
The
choices

are

as

follows:

•
Allow—The
ACE

is

to

permit

the

status

of
the
Urgent
control

bit.

•
Clear—The
ACE

is

to

set

the

Urgent

control

bit

to
0
(zero)
and
thereby
invalidate

the

Urgent
Pointer
which

provides

information.
TCP

Factor
TCP
window

scale

factor.

The

TCP

window

scaling

extension

expands

the

definition

of

t

he

TCP
window
to

32

bits

and

uses

a

scale

factor

to

carry

the

32-bit

value

in

the

16-bit

window

of

the

TCP
header.
Increasing

t

he

window

si

ze

improves

TCP

performance

i

n

network

paths

with

large
bandwidth,
long-delay

characteristics.
Valid
entries

are

from

0

to

14

(the

maximum

scale

factor).
For
more

on

TCP

window

scaling,

refer

to
