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.
