Results (ARS)
•Without TPS or ARS, the delay of two voice calls from
the NOC were both 1.4 +/- 0.3
seconds at high load, far less than an generally accepted maximum of 500 ms.
•In order to improve utilization of the network, an MPLS
overlay was introduced to allow
traffic travelling to Ship 4 to take different
routes depending on the application type and priority.
•In this case high
priority voice traffic was to travel via Ship 3 while all other traffic will travel over the default route via
Ship 1.
•With the combination of TPS and ARS, the impact on the
delay of voice packets is
significant.
•The high-priority
voice call which is taking the alternate lightly loaded route via Ship 3 has a delay of 0.19 +/- 0.03
seconds while the lower
priority voice call which uses the default route has a delay of 0.43 +/- 0.10 seconds.
