The CMTS has evolved over time, becoming a CCAP supporting both highspeed data and video services. As bandwidth capacity needs grow rapidly, there is increasing pressure on the infrastructure, and new Distributed CCAP Architectures are emerging to address the need for smaller scope, more flexible options.
Distributed CCAP implementations can bring significant benefits in certain HFC network deployments. It will enable higher PHY layer performance for DOCSIS 3.1, and reduce space and power needs at the headend. The paper describes various CCAP architectures and how they handle data and video.
