Abstract: Ensuring the high availability of a Passive Optical Network (PON). A broadband network architecture comprises (a) at least a portion of optical fiber in a communication path to individual subscriber premises, (b) one or more software-implemented Optical Line Terminal (OLT) Controllers, (c) one or more software-implemented Service Provisioning Applications (SPAs), and (d) one or more software-implemented Broadband Network Gateways (BNGs). Each of the one or more OLT Controllers, one or more SPAs, and one or more BNGs execute on Commercial Off-the-Shelf (COTS) computer systems and entirely upon a plurality of protection groups. Each of the plurality of protection groups consists of a plurality of pods. The pods in a particular protection group which are active are dynamically adjusted to ensure the high availability of the broadband network architecture.

Abstract: A method for providing video to a customer premises equipment, the method includes: receiving, by a radio frequency interface of a cable modem, radio frequency signals; receiving by a data tuner out of multiple tuners of the cable modem, radio frequency signals that convey data; detecting, by a monitor of the cable modem, a request to receive a certain video channel that is being broadcasted; wherein the request is sent to the cable modem from a customer premises equipment; tuning a certain tuner out of multiple tuners of the cable modem, in response to a mapping between radio frequencies and video channels, to receive the certain video channel; filtering out data layer encapsulation information that encapsulates certain video channel information; and transmitting certain video channel information to the customer premises equipment.

Abstract: A method for testing a device of a cable modem system includes specifying a MAC address for the device under test, specifying one or more test messages for the devices under test, specifying a mode of failure for the messages, sending the messages to the device under test according to the failure mode and determining whether the device under test and other devices of the system respond correctly.
