Re: [RPRWG] More comments on preemption



Dear Pankaj
 
I aggree with your first remark below, but the second one cannot be serious with respect to voice communications and long data packets.
 
Best regards, Harmen
 
A need for preemption due to jitter/latency fears is unfounded. I don't know
of any application where a few microseconds (even a few tens of
microseconds) will make a huge difference. Should there be networks where
this does become a big issue, routers can always negotiate a smaller MTU.
 
And, at lower rates everything runs at a lower rate (including
high-priority traffic) so there should not be an extra concern for latency.
