Re: [RE] [REInterestGroup] Latency critical RE and SRP

Dear Qi Wu,
 
We all appreciate your interest in the RE SG and
hope that your questions will be answered.
 
SRP deals with bandwidth, because latency is impossible
to guarantee if the link bandwidth is exceeded.
 
Once the bandwidth is guaranteed, then "pacing" deals
with guaranteed latency. Some pacing descriptions
are present in the posted working paper.
 
The concept of pacing is _not_ to have the lowest
latency, but to have a _guaranteed_ reasonably low
latency through bridges.
 
The working paper (that also describes SRP) is being
updated to include more pacing details. The update should
be available within the week.
 
I hope that helps answer your question.
 
DVJ

Dear All:

    The key application scenaio in RE working paper is the latency
sensitive interactive audio recording. However, the SRP only deals with
bandwidth reservation. Why SRP focus on bandwidth instead of delay?
Does enough bandwidth result in low delay?
