[ns] enabling ECN in ns2

[Keerthi M]

Hi,

I was trying to enable ecn capability in ns2 by setting agent/tcp ecn_ 1.
But in the trace file(wired network) only the first of the seven flag
fields show C. I guess its just ecn echo.

Could someone please help me with this.

Regards,

[ns] How to change default values in ns-default.tcl

[Keerthi M]

Hi,

I want to change some of the default values of RED protocol in NS. I tried
setting new values in ns-default.tcl and re-compiled, but when I run the
simulation NS uses the old default values instead of new ones. Can anyone
please tell me how to change the default values in ns?

Thank you,
Keerthi
