Media Bandwidth Management

Advanced Setup

This chapter describes bandwidth management with one level of child class. This chapter applies to the P-660H-D.

16.1 Media Bandwidth Management Overview

Bandwidth management allows you to allocate an interface’s outgoing capacity to specific types of traffic. It can also help you make sure that the Prestige forwards certain types of traffic (especially real-time applications) with minimum delay. With the use of real-time applications such as Voice-over-IP (VoIP) increasing, the requirement for bandwidth allocation is also increasing.

Bandwidth management addresses questions such as:

•Who gets how much access to specific applications?

•What priority level should you give to each type of traffic?

•Which traffic must have guaranteed delivery?

•How much bandwidth should be allotted to guarantee delivery?

Bandwidth management also allows you to configure the allowed output for an interface to match what the network can handle. This helps reduce delays and dropped packets at the next routing device. For example, you can set the WAN interface speed to 1024 kbps (or less) if the ADSL connection has an upstream speed of 1024 kbps.

Refer to Section 16.11 on page 167 to enable and configure bandwidth on the interfaces.

Refer to Section 16.12 on page 168 to configure bandwidth classes.

Refer to Section 16.13 on page 174 to view bandwidth usage information.

You can use the wizard setup screens to configure basic bandwidth management. Refer to Chapter 1 on page 38 for more information.
