ABOUT DOCSIS

DOCSIS (Data Over Cable Service Interface Specification) is an international standard developed by CableLabs. It defines the communications and operation support interface requirements for sending data over the cable system. It permits the addition of high-speed data transfer to an existing cable TV (CATV) system.

HISTORY of DOCSIS

The first DOCSIS specification was version 1.0, issued in March 1997, with revision 1.1 (adding quality of service (QoS) capabilities) following in April 1999. Because of increased demand for symmetric services such as IP telephony, DOCSIS was revised again to enhance upstream transmission speeds. DOCSIS 2.0 was released in December 2001. Most recently, the specifications were revised to significantly increase transmissions speeds (this time both upstream and downstream) and introduce support for Internet Protocol version 6 (IPv6). 

Current version, DOCSIS 3.0, was released in August 2006. DOCSIS 3.0 features management over IPv6 and channel bonding, which enables multiple downstream and upstream channels to be used simultaneously by a single subscriber.
