Re: [RAM] The mapping problem: rendezvous points?

[Spencer Dawkins <[e-mail]>]

I may be misunderstanding Lars, but I understood his point to be that, 
unless the host is opening two connections back-to-back, there is no ARP 
cache miss/queuing going on, and you don't normally lose the first packet of 
a TCP connection ("3 second timeout"), unless you're really seeing 
congestion (which is where you'd need to wait for a chile, anyway).

I understood his concern to be making sure we don't move from a network 
where we see 20-200 ms ARP cache timeout/queuing to a network where we see a 
3-second timeout at the beginning of every TCP connection. These would not 
be packet drops that have gone unseen for decades.

Thanks,

Spencer
