Chapter 3. Deploying IPv6 in Cable Networks
In this chapter we discuss IPv6 deployment in cable networks, providing an overview of key network elements, different deployment models, and challenges in deploying IPv6 over a cable network.
Most equipment used in cable networks today conforms to the data over cable service interface specifications (DOCSIS) standard. DOCSIS defines the communications and operations support interface requirements for data over cable systems. The specification permits high-speed data transmission over an existing cable TV (CATV) network. It is employed by many multiple system operators (MSOs) to provide Internet access over their existing hybrid fiber coaxial (HFC) infrastructure. The first DOCSIS specification, version 1.0, which was published in March 1997, provided best effort (BE) data services to end users. DOCSIS 1.1, which was released in April 1999, allowed MSOs to deploy real-time services, such as IP telephony, by adding quality of service (QoS) capabilities to the upstream. In December 2001 the specification was again revised and released as DOCSIS 2.0, providing enhanced upstream transmission speeds. This catered for increased demand for symmetric services by business customers and a rise in peer-to-peer applications. DOCSIS 3.0, published in August 2006, specified increased transmissions speeds, this time for both upstream and downstream. This version also introduced support for several new features, including IPv6.
