Solutions for upstream channel bonding

摘要

A cable modem that supports stateless requesting and/or limited contention-based requesting is provided herein. In an example, a physical layer (PHY) configured to communicate over a plurality of upstream channels is provided. A bandwidth requestor is provided to request bandwidth using contention-based requesting over a first subset of the upstream channels for contention-based flows and request bandwidth using stateless requesting over a second subset of the upstream channels for stateless flows.
