PacketCable Multimedia Overview
PacketCable Multimedia (PCMM) is a CableLabs specified framework which defines an architecture for deployment of QoS-
enabled, general multimedia services. This framework leverages DOCSIS QoS functionality and is founded on much of the
functionality that was defined in PacketCable Voice-only architectures. The architecture of PacketCable 1.x was customized
for delivering residential telephony, but PCMM is designed for the delivery of a variety of multimedia services (i.e., Video
Phone, IP Video, and SIP Voice) requiring QoS treatment. PCMM specifically addresses the issues of policy authorization,
QoS signaling, resource accounting, and security.
The primary benefit of PCMM is that it gives control of special services to the cable operator. Among the advantages of
PCMM are the following:
Good, Better, Best service delivery options to the subscriber
Efficient use of bandwidth and QoS services on an as needed basis
New revenue sources from these additional services
Higher subscriber satisfaction because subscribers are paying for the services they want.
The ARRIS implementation of PCMM is based on the C4/c CMTS's carrier class redundancy, high-speed architecture, and
DOCSIS QoS capabilities, which are described elsewhere in this document.
PacketCable Multimedia supports IPv6 addresses for Classifiers and Subscriber IDs. IDs. A single PCMM gate for an
upstream or downstream flow can simultaneously use both an IPv4 and IPv6 classifier and exist within one dynamic flow.
For greater detail see Sections 6.13, 6.1.5, 6.4.2.3, and 6.4.2.6 of the Packet Cable Multimedia Specification, (PKT-SP-MM-
I06-110629). Note that Engineering Change Notice (ECN) MM-N-07.0430-3 has been incorporated into the PCMM
specification. This ECN defines the IPv6 extensions for PCMM.
