[Klug-general] Wan optimisation

[James Blake]

Are the leased lines standard BT MegaStreams (do they have copper X21  
connectors into the wall sockets)?

If you do compression at lower layer you'll see benefit (although  
marginal) even if the data is compressed at the higher levels because  
of the duplication in the protocol overhead.  If you're not  
compressing, you see a massive benefit from compressing at a lower  
layer.  As well as Riverbed as mention before, boxes like Peribit,  
Packeteer, Expand and Exinda all do this kind of thing.

James
