Options:

Mark the VoIP service as EF, set the CIR to 1 Mbit/s, and set the PIR to 1 Mbit/s; mark the video service as AF4, set the CIR to 2 Mbit/s, and set the PIR to 2 Mbit/s; mark key data services as AF1, set the CIR to 2 Mbit/s, and the PIR to 5 Mbit/s; mark other services as BE, set the CIR to 0 Mbit/s, and set PIR to 5 Mbit/s.
