[Iccrg] RE: how fast do modern high-speed TCPs go?

[Murari Sridharan]

Very few E2E 10G WAN paths although thats changing, the core mostly is already 10G. I'd say most of the high speed versions can easily fill multi-gpbs on WAN. Anything past 10G i have only played with on LAN using Infiniband NICs. 

The latest comprehensive fairness report came out of NIST a couple of years back.

Subject: [Iccrg] how fast do modern high-speed TCPs go?

Hi,

pretty basic question: how fast do modern high-speed TCPs go over WAN paths?

More specifically, can they fill a multi-Gbps or even tens-of-Gbps paths? Under what path conditions (reserved capacity?), using what hardware? Can they still be called fair to regular TCP in case the path has cross or other traffic?

Does anyone have a quick pointer to some recent papers?

Thanks,
Lars
