US Patent 11005618 Adaptive high efficiency, low latency DOCSIS PGS scheduler

Determining when to provide a Proactive Grant Service (PGS) scheduling grant. A plurality of PGS grants are issued to a cable modem (CM). The PGS grants that were utilized by the CM are monitored as well as those PGS grants that were not utilized by the CM. A compromise PGS grants pattern for that CM is generated based on the observations of which PGS grants the CM utilized and which PGS grants the CM did not utilize. The compromise PGS grants pattern for that CM optimizes a projected experienced latency and jitter for particular data flows of the CM verses a projected wasted upstream capacity.
