Abstract: An upstream bandwidth allocation method, apparatus, and system. The method includes obtaining, by a cable modem termination system (CMTS), a service flow attribute of each online cable modem (CM) of one or more online CMs, where the service flow attribute comprises at least one delay-sensitive service and a delay-insensitive service, allocating, by the CMTS, an upstream bandwidth to each online CM according to a received service request, and obtaining a remaining bandwidth that is a remaining part in a preset total bandwidth other than the upstream bandwidth that is allocated to each online CM according to the service request, allocating, by the CMTS, at least a part of the remaining bandwidth to a CM whose service flow attribute is a delay-sensitive service, and informing, by the CMTS, each online CM of the one or more online CMs of an upstream bandwidth allocation result.

Abstract: Embodiments provide a method and an apparatus for controlling a scheduling packet. The method is applied to an HFC network system. The method includes: determining, by a network device, a transmission bandwidth of a first scheduling packet; determining a target quantity according to a first control threshold when the transmission bandwidth of the first scheduling packet is greater than or equal to the first control threshold, where the target quantity is less than or equal to a quantity of IEs included in the first scheduling packet; and generating a second scheduling packet according to the target quantity, where a quantity of IEs included in the second scheduling packet is less than the target quantity, the second scheduling packet includes an IE used to carry resource allocation information for a second uplink period, and the second uplink period follows the first uplink period.
