I am currently involved in a British Standards exercise looking at
Time Critical Communication Architectures (TCCA) in the context of
the OSI reference model. We are currently examining metrics for network 
performance so that users may have some tools to use in the choice of
or configuration of time critical networks.

We find the current means of quantifying performance (ie. octects per
second through layers etc.) to be rather unsuitable for our purposes. I
have seen some discussion on the list about the optimization of ASN.1
encoding and the metrics used for that purpose. My questions are...

 - Have any metrics for the performance of layered protocols been 
   defined in the time domain;   

 - Are any other groups addressing this problem;

We are interested in any input in this area and are particularly 
concerned that we do not replicate any effort already expended in 
this area.

Any assistance/information would be most welcome.

Ivan
