ABSTRACT:
Scheduling virtual upstream channels within one physical upstream channel is disclosed. The MAP messages of the virtual upstream channels that share the same physical upstream channel are synchronized together such that any one transmission opportunity for a given virtual upstream channel does not overlap with transmission opportunities of any other virtual channel. This includes converting all requests for tranmission opprotunities into a common unit and then scheduling these requests as appropriate.
