Media Bandwidth Management

This chapter contains information about configuring media bandwidth management, editing
rules and viewing the Prestige's media bandwidth management logs.

20.1 Media Bandwidth Management Overview

ZyXEL's Media Bandwidth Management allows you to specify bandwidth management rules
based on an application and/or subnet. You can allocate specific amounts of bandwidth
capacity (bandwidth budgets) to different bandwidth rules.
The Prestige applies bandwidth management to traffic that it forwards out through an
interface. The Prestige does not control the bandwidth of traffic that comes into an interface.
Bandwidth management applies to all traffic flowing out of the router, regardless of the
traffic's source.
Traffic redirect or IP alias may cause LAN-to-LAN traffic to pass through the Prestige and be
managed by bandwidth management.
• The sum of the bandwidth allotments that apply to the WAN interface (WAN to LAN,
LAN to WAN, WAN to WAN / Prestige) must be less than or equal to the WAN BW
Budget that you configure in the Media Bandwidth Management Configuration
screen.
• The sum of the bandwidth allotments that apply to the LAN port (LAN to WAN, WAN to
LAN, LAN to LAN / Prestige) must be less than or equal to 100,000 kbps (you cannot
configure the bandwidth budget for the LAN port).
• The sum of the bandwidth allotments that apply to the WLAN port (WLAN to WAN,
WAN to WLAN, WLAN to WLAN / Prestige) must be less than or equal to 54,000 kbps
(you cannot configure the bandwidth budget for the WLAN port).

20.1.1 Application-based Bandwidth Management Example

The bandwidth rules in the following example are based solely on application. Each
bandwidth rule (VoIP, Web, FTP, E-mail and Video) is allotted 128 Kbps.
