Bandwidth on Demand

The Bandwidth on Demand (BOD) feature allows you to bundle both B
channels in one connection. The second channel is added and
subtracted dynamically according to traffic demand. The Prestige uses
the Bandwidth Allocation Control Protocol (BACP) and the Multilink
Protocol (MP) to implement bandwidth on demand.

The configuration of bandwidth on demand focuses on the Base
Transmission Rate (BTR) and the Maximum Transmission Rate (MTR).
The relationship between BTR and MTR are shown below:

BTR & MTR Setting
