Techniques that assist in processing of failure detection protocol (FDP) packets. Techniques are provided that assist a CPU of a network device in processing incoming FDP packets. In one embodiment, only a subset of FDP packets received by the network device is forwarded to the CPU for processing, the other FDP packets are dropped and not forwarded to the CPU. In this manner, the amount of processing that a CPU of the network device has to perform for incoming FDP packets is reduced. This enables the network device to support newer FDPs with shorter periodic interval requirements.

Techniques for processing incoming failure detection protocol packets

A system and method for communication over a single communication line. The system includes an interface logic component for sending and receiving information for a processing component. The system further includes a single line interface module for sending and receiving data over a single communication line. The single line interface module uses a preamble for sending and recovering a clock signal for sending and receiving data over the single communication line.

Techniques are provided for assisting in the processing of failure detection protocol (FDP) packets. Techniques are provided that assist a CPU of a network device in processing incoming FDP packets. In one embodiment, only a subset of FDP packets received by the network device is forwarded to the CPU for processing, the other FDP packets are dropped and not forwarded to the CPU. The processing is performed using dual memory structures that enable receipt of FDP packets by the network device to be decoupled from the processing of FDP packets by the CPU of the network device.

Techniques for using dual memory structures for processing failure detection protocol packets

Techniques that assist in processing of failure detection protocol (FDP) packets. Techniques are provided that assist a CPU of a network device in processing incoming FDP packets. In one embodiment, a module is provided in a network device for detecting and flagging the non-receipt of FDP packets by the network device for one or more FDP sessions. In this manner, the task of detecting non-receipt of FDP packets is offloaded from the CPU of the network device. This enables the network device to support newer FDPs with shorter periodic interval requirements.
