Abstract
A method and apparatus for allocating upstream channel resources in a hybrid fiber coaxial (HFC) network are provided. A cable modem termination system (CMTS) previously provides cable modems (CMs) with a plurality of burst profiles through an extended interval usage code (IUC) of an upstream channel descriptor (UCD) message, and allocates resources to CMs by using an optimized burst profile according to an upstream channel status, thereby increasing transmission efficiency of an upstream channel.
