[c-nsp] re: 2600 load balancing

[Vandy Hamidi]

Josh,
Just thought I'd add some slightly tangential info.

If you have limited bandwidth, check out header compression as well as
PPP Packet Compression.  It increases the latency, BUT if you have a
powerful enough router OR a little latency isn't a huge deal, it could
increase your B/W quite a bit.

By the way, header compression helps most will small packets (e.g.
voice).  Packet compression won't help much if you are using compressed
voice already.

Interesting.  I knew MLPPP avoided the out of order packet problem by 
putting packets back in order at the end of the bundle, but I wasn't 
aware of the interleaving feature.  

Definately need to setup Cisco MLPPP in the lab.

Thanks,

Josh
