Fw: [Csci551-talk] Question on Load Sensitive Routing Example

[Coolrocks]

Oops, the first message turned out to be unexpectedly messy, let me try
again:)

I have the same doubt as Min: Shouldn't router 5 be considered as an
originator, not a forwarder? Otherwise printing out
"data-packets-originated" in stage 6 will be meaningless, i.e. there will be
no "data packets originated" but only ones that are forwarded. Unless
"forwarded data packets" in stage 6 has a different "definition" in stage
7??

Please clarify!
Thanks
