Abstract:
1. A network device, comprising: a cell processing unit configured to receive incoming data cells from a network for a plurality of communication channels; a timer configured to provide a timer value to said cell processing unit; and a memory coupled to said cell processing unit and configured to store one or more policing parameters and rollover data for each of the communication channels, wherein the rollover data comprises an indication of a rollover relationship between the timer value and one of the policing parameters for each of the communication channels; wherein for each received incoming data cell, said cell processing unit is configured to assign an arrival time from the timer value and compare the received incoming data cell's arrival time to the one or more policing parameters for the received incoming data cell's communication channel to determine if the received incoming data cell is conforming or non-conforming to a rate for the communication channel, wherein said cell processing unit is configured to access the rollover data for the received incoming data cell's communication channel to account for the rollover relationship when comparing the arrival time to the one or more policing parameters; and wherein said memory is further configured to store operations and maintenance data indicating connection availability information for each communication channel.
