Method and system for a low-power client in a wide area network
First Claim
1. A method comprising:
- in a network device;
connecting and registering with a cable modem termination system (CMTS);
sending a sleep request to said CMTS;
receiving a first message from said CMTS that indicates that a media access control (MAC) management message will be transmitted by said CMTS after a predetermined time interval;
subsequent to receiving said first message, powering down one or more components of said network device and setting a sleep timer to a value equal to the duration of said predetermined time interval minus a transition period; and
powering up said one or more components of said network device upon expiration of said sleep timer.

Abstract
A network device may be operable to receive an indication from a cable modem termination system (CMTS) that media access control (MAC) management messages will be transmitted by the CMTS at fixed intervals. Subsequent to receiving the indication, the network device may be operable to power down one or more components of the network device and set a sleep timer to a value equal to an integer multiple of the fixed interval minus a transition period. The network device may power up the one or more components of the network device upon expiration of the sleep timer. The network device may power up the one or more components of the network device upon an amount of traffic in a buffer of the network device reaching a threshold.

9. A system comprising:
-
circuitry for use in a network device, said circuitry being operable to; connect and register with a cable modem termination system (CMTS); send a sleep request to said CMTS; receiving a first message from said CMTS that indicates that a media access control (MAC) management message will be transmitted by said CMTS after a predetermined time interval; subsequent to reception of said first message, power down one or more components of said network device and setting a sleep timer to a value equal to the duration of said predetermined time interval minus a transition period; and power up said one or more components of said network device upon expiration of said sleep timer. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
