How effective is 'sorting by datagram size' as a means of preferring
interactive traffic over say, ftp? I can imagine this gets keystrokes
through fast, but the responses which are typically larger would'nt get
preferred treatment.

Given that most host implementations  dont fill in the TOS field in 
a usable manner, what's the most simple and effective approach? Looking at
the port numbers at the gateway and queuing telnet and rlogin segments before
batch style traffic? 

Should one  use a single queue, and sort in segments according to a strategy,
or use several queues with different priorities?
