DOCSIS®: The Past and The Future
The four successive versions of the DOCSIS® cable modem: DOCSIS® 1.0, DOCSIS® 1.1, DOCSIS® 2.0, and DOCSIS® 3.0, provide increasing levels of capabilities and functionality, while maintaining multi-vendor interoperability and full backward and forward compatibility of DOCSIS®.
Features
DOCSIS® 1.0 provides basic broadband Internet connectivity for one or more devices in the home. Among other things, it includes the ability to rate-limit (cap) a particular customer's data rate to a cable operator selected value.
DOCSIS® 1.1 provides improved operational flexibility, security, and quality-of-service (QoS) features.
DOCSIS® 2.0 includes increased upstream reliability and throughput for symmetric services.
DOCSIS® 3.0 provides a number of enhancements, most notably, channel bonding, support for IPv6,and support for IPTV. Channel bonding provides cable operators with a flexible way to significantly increase speeds to customers, with compliant devices supporting up to at least 160 Mbps in the downstream and 120 Mbps in the upstream.
Benefits
DOCSIS® 1.0 cable modems made the interoperability of cable technology a reality for cable operators and cable subscribers.
DOCSIS® 1.0 made the standardization of cable modems possible. As a result, placed downward pressure on cable modem prices causing them to drop from $500 to $50.
DOCSIS® 1.1 enables the cable operator to configure guarantees on the data rates and/or the latency of the service.
DOCSIS® 2.0 increases upstream throughput to 27 Mbps of capability.
DOCSIS® 3.0 will allows cable operators to provide data rates in the hundreds of megabits.
Services Enabled
DOCSIS® 1.0 provides the cable industry-platform the delivery of high-speed data on cable modems.
DOCSIS® 1.1 paves the way for high-quality digital voice, interactive gaming, and commercial service level agreements (SLAs).
DOCSIS® 2.0 increases upstream throughput resulting in an increase in the capacity to deliver high-speed data.
DOCSIS® 3.0 enables direct competition with VDSL and FTTX service offerings from the telcos, and provides a platform for the evolution of the cable video business into IPTV.
