This table compares typical throughputs of sample service classes. Each advertised subscriber service should have a
corresponding SCN. These SCNs are called on by the configuration files used to register CMs and by the C4/c CMTS to build
SFs for subscribers.
Additional Service Flows
Additional service flows could be added using the following service class examples:
VoIPup:
Scheduling Type = 5 (UGS with activity detection schedule type).
A strict priority flow configured for G.711 voice.
VoIPdown:
Scheduling Type = 0.
Traffic Priority = 7 (a strict priority flow).
MPEGup:
Scheduling Type = 4 (real time polling service schedule type).
A strict priority flow. Each tiered service could have flow parameters adjusted to provide greater throughput for
higher tiers.
MPEGdown:
Scheduling Type = 0.
Traffic Priority = 6 (a strict priority flow).
FTPup:
Scheduling Type = 3 (Non real time polling service schedule type).
A weighted round robin flow. This could have a Traffic Priority of 2.
FTPdown:
Scheduling Type = 0.
