-andreas [who has to explain this about once a week to customers who think that they bought a GigE connection but then can't "ftp" a file from coast to coast at 1Gbps throughput. Use multiple TCP streams!]
Yeah, try explaining to a VSAT customer why they don't get 10Mb/s on their 10Mb/s VSAT connection with a 600ms RTT!
The response is.. "I don't care, I want my 10Mb/s!"...
In the 3G world, i have had good results overcoming longish RTT by using the Hybla TCP algorithm http://hybla.deis.unibo.it/ I am hoping it gets more default traction, especially in wireless where the radio link is a pretty big latency source Cameron
