satelline channel acceleration

[jouk]

Hello,

I use cisco routers (2800 and 3600 series) at satellite link and I have a problems with slow download speed when getting files by FTP and WEB surfing. Can you give an advice what to do to solve this issue ?

Hello Jouk,

the TCP extended window can be negotiated by endpoints to improve performance on a high delay link

http://www.ietf.org/rfc/rfc1323.txt

see also

http://www.psc.edu/networking/projects/tcptune/

this second link provides procedures on how to enable TCP extended window on several operating systems

the constraint is that both sides have to negotiate this capability at TCP session setup.

Hope to help
