Re: [ns] DS RED parameters

[Onno Kievit <okievit@lucent.com>]

Read the manual Nortel networks has provided along with the DS module. It
says:

$dsredq configQ (physical queue) (virtual queue) Min_th Max_th Max_p

So your 0.02 is the RED Max_p parameter.

If you want to know how RED works and how you must configure RED, read this
paper:

D. Clark and W. Fang, "Explicit Allocation of Best Effort Packet Delivery
Service," CAN Transactions on Networking, 1998.


Kind regards,
