BCM50a Integrated Router Configuration — Basics
Chapter 15
Bandwidth management
This chapter describes the functions and configuration of bandwidth management.
Bandwidth management overview
With bandwidth management, you can allocate the outgoing capacity of an
interface to specific types of traffic. It can also help you make sure that the
BCM50a Integrated Router 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?
• Which traffic must have guaranteed delivery?
• How much bandwidth is allotted to guarantee delivery?
With bandwidth management, you can 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 1 024 kb/s (or less) if the broadband device connected to the
WAN port has an upstream speed of 1 024 kb/s.
