Chapter 18
Media Bandwidth Management
This chapter contains information about configuring media bandwidth management, editing rules
and viewing the Prestige’s media bandwidth management logs.
18.1 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).
18.1.1 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.
