Method and system for cross-protocol time synchronization

A method for communication, the method comprising:

• in a premises-based network:
• receiving a signal that conforms to a data over cable service interface specification (DOCSIS) communications protocol;
• extracting a global time of day (GTOD) clock from said received signal;
• and
• synchronizing communication on the premises-based network in accordance with a multimedia over cable alliance (MoCA) communications protocol, based at least in part on said extracted GTOD clock.

A system for communication, the system comprising:

• one or more circuits for use in a premises-based network, said one or more circuits being operable to:
• receive a signal that conforms to a data over cable service interface specification (DOCSIS) communications protocol;
• extract a global time of day (GTOD) clock from said received signal;
• and
• synchronize communication on the premises-based network in accordance with a multimedia over cable alliance (MoCA) communications protocol, based at least in part on the extracted GTOD clock.

A system for communication, the system comprising:

• a multimedia over cable alliance (MoCA) network controller in a premises-based network, said MoCA network controller being operable to:
• receive a DOCSIS signal;
• extract a global time of day (GTOD) clock from said received DOCSIS signal;
• and
• synchronize transmission of signals on a MoCA network based, at least in part, on said extracted GTOD clock.
