Abstract:
A method for monitoring current buffer contents, comprising:receiving received data units corresponding to a plurality of streams, wherein each stream of the plurality of streams is identified by a stream identifier; for each received data unit as the received data unit is received: determining a stream identifier for the received data unit; utilizing the stream identifier for the received data unit to retrieve a plurality of independent group identifiers to which the received data unit corresponds; and incrementing count values corresponding to at least a portion of the plurality of independent group identifiers to which the received data unit corresponds; storing the received data units in a buffer to produce stored data units; fetching the stored data units from the buffer to produce fetched data units; transmitting the fetched data units as transmitted data units; and for each transmitted data unit as the transmitted data unit is transmitted: determining a stream identifier for the transmitted data unit; utilizing the stream identifier for the transmitted data unit to retrieve a plurality of independent group identifiers to which the transmitted data unit corresponds; and decrementing count values corresponding to at least a portion of the plurality of independent group identifiers to which the transmitted data unit corresponds.
