Slide 42 of 47
Notes:
Nb one way response time very important for voice, need to be better than 100 msec or people start stepping into one another’s conversations.
PC Hardware with GPS located at ANS & 23 CSG partner sites
Measure one way loss & response time using clock synchronization, metrics defined by IETF/IPPM
8 sites now operational, monitor 56 paths ((N-1)*N)
Results show can have big asymmetries (asymmetric loading & routing)
Willing to deploy (at their cost) at 5 DOE sites
