thread the crap out of whatever it is your transactioning across the link
to make up for TCP's jackknifes...
What is a TCP jackknife?

It is also called a sawtooth or similar terms. Just google tcp
sawtooth and you will see many references, and images that depict the
traffic pattern.

Thanks Fred. Sawtooth is more familiar.
How much of that do you actually see in practice?
Cheers,
Jakob.

Sorry; yes Sawtooth is the more accurate term. I see this on a daily
occurance with large data-set transfers; generally if the data-set is large
multiples of the initial window. I've never tested medium latency(
100ms) with small enough payloads where it may pay-off threading out many
thousands of

Thanks for your comments, whilst I know you can optimize servers for TCP
windowing I was more talking about network backhaul where you don't have
control over the server sending the traffic.
If you don't have control over the server,

I may be needing 10 gig from the West Coast to the East Coast some time in
the next year. I've got my ideas on what that would cost, but I don't have
anything that big.
This could be a leased line, part of a cloud with Verizon, NTT, Sprint, or
whoever as the provider, etc. I'm just

Might want to be more specific. Catalina Island, CA to Buxton, NC
(home of Cape Hatteras High School) will probably be way different
than downtown LA to downtown Boston.
Fair enough
Seattle to Boston is the general route, real close.

10 gigs of bare naked fiber is one thing, but if you need extra paths
redundancy, figure that out now and specify.
Is this latency, bandwidth, both? Mission critical, business critical,

I'm looking for options.
With dark fiber, obviously, I have the ultimate in options.
However, its the ultimate in cost as you say.
The requirement we have is 10gig of actual throughput. Precisely what mechanism
is used to transport it isn't all that important, though I'm certain that there
I've had pretty good luck with CenturyLinks 10G wave offerings:
