Triple-Play Service Deployment

Chapter 10: Service Assurance for Triple-Play Services
Active service emulation
Active service emulation offers the service provider the capability
to reproduce customer or network problems. The technician can
emulate the customer scenario by mimicking traffic priority
settings, codec selection, etc., in order to quickly validate the
degradation. Hardware probes and software agents can be
deployed at key points in the network such as content injection
points and key handoff points and at the customer premises. This
makes it possible to quickly sectionalize the network by running
service emulation tests between the various identified end points
along the service delivery path.
