Port Range Triggering

3425-00669 Rev E

101

Port Range Triggering

The Port Range Triggering screen allows the Gateway to watch outgoing data for

specific port numbers. The IP address of the computer that sends the matching data

is remembered by the residential gateway, so that when the requested data returns

through the residential gateway, the data is pulled back to the proper computer by

way of IP address and port mapping rules.

Path:

Applications & Gaming > Port Range Triggering

To trigger a port range, enter the information on each line for the criteria required.

Application Name

—

Enter the unique application name of the trigger.

Triggered Range

—

For each application, enter the starting and ending port numbers

of the triggering port number range. These are the ports used by initiating traffic.

Check with the Internet application documentation for the port number(s) needed.

Protocol

—

For each application, select the appropriate protocol, TCP(6) or UDP(17).

Forwarded Range

—

For each application, enter the starting and ending port

numbers of the forwarded port number range. These are the ports used by incoming

traffic. Check with the Internet application documentation for the port number(s)

needed.

Allow Multiple Hosts

—

Select this option to allow multiple hosts in returned traffic.

QoS (Quality of Service)

103

QoS (Quality of Service)

Quality of Service (QoS) ensures better service to high-priority types of network

traffic, which may involve demanding, real-time applications, such as

videoconferencing.

Note:

The residential

gateway’s QoS is for upstream traffic regulation only.

Downstream QoS is usually enforced by the service provider’s headend equipment.

Path:

Applications & Gaming > QoS

Application-based QoS manages information as it is transmitted and received.

QoS

—

To use QoS, select Enabled. Otherwise, keep the default, Disabled.

Default Queue Index

—

Select the default queue (and priority) for applications not

specified below: 1-8. (A lower value has higher priority.)

Queue Management

—

A new window appears. Continue with the next section for

details.

Queue Management

Path:

Applications & Gaming > QoS > Queue Management button

The Queue table specifies the number and types of queues, queue parameters,

shaping behavior, and scheduling algorithm to use.

Each queue can be

configured to be a “Strict Priority”, “WRR (Weighted Round

Robin)”, or “WFQ (Weighted Fair Queuing)” queue.

One of the queues is

configured to be the default queue, which matches all traffic that cannot be classified

by the existing classification rules. The default settings are as follows:



Queue 1, 2, and 3 are Strict Priority queues (queue 1 has the highest priority)



Queue 4, 5, and 6 are WFQ queues and share the same priority (lower than 1, 2,

and 3)



Queue 7 and 8 are also WFQ queues but with the lowest priority



Queue 8 is set to be the default queue

Note

: We recommend that you use the default settings or those set by your service

provider.

Queue Index

—

There are eight queues for each interface. You can configure the

parameters but cannot add or delete queues. Higher index queues generally

represent higher-priority queues. Queues 1-3 are Strict Priority (WP) queues, and

Queues 4-8 are priority-based Weighted Fair Queues (WFQ).

Precedence

—

Enter the Precedence value of this queue relative to the others. A lower

value indicates higher precedence.

Scheduler

—

Select the scheduling algorithm:

SP

,

WFQ

, or

WRR

(Weighted Round

Robin). The default is

SP

.

Dropper

—

Select the dropping algorithm used if there is congestion:

RED

(Random

Early Detection),

DT

(Drop Tail), or

WRED

(Weighted RED). The default is

WRED

.

Weight

—

When WFQ or WRR is used, this option is available and used only for

queues of equal precedence. Queues 4-6 have equal precedence, and Queues 7-8

have equal precedence. Queues 1-3 have higher precedence than Queues 4-6, while

Queues 4-6 have higher precedence than Queues 7-8.

Shaping

—

If the Shaping rate is greater than or equal to 100, then it is the percentage

of physical bandwidth. If the Shaping rate is less than 100, then it is the rate in bits

per second. A value of -1 indicates no shaping. The default is

-1

.

Burst Size

—

Enter the Burst Size in bytes (1 to 10485760). For both leaky bucket

(constant rate shaping) and token bucket (variable rate shaping) algorithms, the

Burst Size value is the bucket size and the maximum burst size. If you set this value

to zero, then the Gateway will use the system default Burst Size, which is the current

Shaping rate divided by eight. The default is

0

.
