Multimedia over Coax Alliance
The Multimedia over Coax Alliance (MoCA) is an international standards consortium that publishes specifications for networking over coaxial cable. The technology was originally developed to distribute IP television in homes using existing cabling, but is now used as a general-purpose Ethernet link where it is inconvenient or undesirable to replace existing coaxial cable with optical fiber or twisted pair cabling.
MoCA 1.0 was approved in 2006, MoCA 1.1 in April 2010, MoCA 2.0 in June 2010, and MoCA 2.5 in April 2016. The most recently released version of the standard, MoCA 3.0, supports speeds of up to 10 Gbit/s. This technology is not yet available in customer premises equipment.
The Alliance currently has 45 members including pay TV operators, OEMs, CE manufacturers, and IC vendors.
MoCA's board of directors consists of Arris, Comcast, Cox Communications, DirecTV, Echostar, Intel, InCoax, MaxLinear and Verizon.
Within the scope of the Internet protocol suite, MoCA is a protocol that provides the link layer. In the seven-layer OSI model, it provides definitions within the data link layer (layer 2) and the physical layer (layer 1). DLNA approved of MoCA as a layer 2 protocol. A MoCA network can contain up to 16 nodes for MoCA 1.1 and higher, with a maximum of 8 for MoCA 1.0. The network provides a shared-medium, half-duplex link between all nodes using time-division multiplexing; within each timeslot, any pair of nodes communicates directly with each other using the highest mutually-supported version of the standard.
