The document discusses the evolution and capabilities of DOCSIS (Data Over Cable Service Interface Specification) technology. It notes that DOCSIS 1.0 enabled high-speed internet access over cable networks. DOCSIS 1.1 added quality of service and security features. DOCSIS 2.0 provides increased upstream bandwidth capacity to support symmetric services like voice and peer-to-peer applications. The roadmap outlines continued improvements like DOCSIS in set-top boxes and higher bandwidth to support new services.
