[altq 694] Re: How to configure altq as a RED router

Thank you very much for your advise, Kenjiro san!

I would like to ask one more question.

If I simply think that ALTQ works for only 'packet dropping'
used some probability (such as RED), is the below network topology
more suitable for the purpose?

 +-----------------+           +---------+
 +Server           +-----------+Client   + 
 +(installed ALTQ) + 1000Base  +         +
 +--------+--------+           +---------+
          |      (ti0)
          +------------------(some interface, 1000Base or 100Base)

I understood that ALTQ works at the outgoing device (ti0),
so I think the server also works as a RED router with proper configuration,
and I don't need to gateway overhead with 2 NICs.
Is it right??

I'll try to this.
Please advise the above question.

Thank you very much.
