Abstract :
The DOCSIS standard has provided a basis for the cablemodem market to take off around interoperable, multi-vendor products. The evolution of this standard to include enhanced quality of service (QoS) and enhanced physical layers affords opportunities to deploy QoS intensive applications such as voice over IP, T1 circuit replacement, interactive gaming, multimedia enhanced services and video conferencing as well as address European deployment requirements. This paper addresses the DOCSIS 1.0, 1.1 and the new 1.2 standard and its evolving features, how it compares to the DVB-RC European proposal, and what QoS services and performance levels can be obtained. Detailed analysis of mixed QoS scenarios including multi-tiered committed information rate IP service and voice over IP are presented.
