Hi all, this is my first question to the ccielab mailing list......
I am looking for detailed information regarding load-balancing using Bandwidth-On-Demand.
I have learned (the hard way!) that there is a difference between ppp multilink and BOD.
Compare the following two BRI configurations (basic DDR config assumed):
int bri0
dialer load-threshold 10
and
int bri0
ppp multilink
ppp multilink load-threshold 10
Both will add a second channel when the load reaches 10/255, however in the first case you don't
really have a ppp multlink, only two seperate channels. I know that when you use ppp multilink
packets are actually split, broken apart, and a piece is put on every link in the multilink. So load-
balancing comes naturally.
But what if you use BOD ? if have tested the first config in my lab, and the load doesn't get
distributed fairly on both channels. How can i force the load to be equally balanced in this case ???
Or what load-distribution algoritme is used with BOD ??
