Bandwidth management
This chapter describes the functions and configuration of bandwidth management.

Bandwidth management overview

With bandwidth management, you can allocate an interface's outgoing capacity to
specific types of traffic. It can also help you make sure that the Business Secure
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:
•
•
•
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.
