Chapter 4 Wizard Setup for Media Bandwidth Management

72

The web configurator’s Media Bandwidth Magnt. screens under Wizard Setup allows you 
to specify bandwidth classes based on an application (or service). You can  allocate specific 
amounts of bandwidth capacity (bandwidth budgets) to different bandwidth classes. 

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 Prestige through the interface, 
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.

and advanced configuration. 

The following is a description of the services that you can select and to which you can apply 
media bandwidth management using the Wizard Setup screens.

VoIP (SIP)

Sending voice signals over the Internet is called Voice over IP or VoIP. Session 
Initiated Protocol  (SIP) is an internationally recognized standard for implementing 
VoIP. SIP is an application-layer control (signaling) protocol that handles the 
setting up, altering and tearing down of voice and multimedia sessions over the 
Internet.

SIP is transported primarily over UDP but can also be transported over TCP, using 
the default port number 5060.
