Abstract: A method for classifying the Quality of Service of the incoming data traffic before the traffic is placed into the priority queues of the Active Queue Management Block of the device is disclosed. By employing a range of mapping schemes during the classification stage of the ingress traffic processing, the invention permits the traffic from a number of users to be coalesced into the appropriate Quality of Service level in the device.

Abstract: A device and a method for aggregating and managing large quantities of data are disclosed. The received data are prioritized into high and low priority queues. The device receive memory is partitioned into blocks which are further divided into free list and allocation list. The low priority queues occupy between 1 and 48 blocks and the high priority queues occupy between 1 and 32 blocks. The incoming data are further subjected to Weighted Random Early Detection (WRED) process that controls congestion before it occurs by dropping some of the queues. The stored data are read using Modified Deficit Round Robin (MDRR) approach. The invention further employees several different filtering approaches for prioritizing data.

Abstract: A device and a method for aggregating and managing large quantities of data are disclosed. The received data are prioritized into high and low priority queues. The device receive memory is partitioned into 1 Kilo byte (1 KB) blocks which are further divided into free list and allocation list. The low priority queues occupy between 1 and 48 blocks and the high priority queues occupy between 1 and 32 blocks. The incoming data are further subjected to Weighted Random Early Detection (WRED) process that controls congestion before it occurs by dropping some of the queues. The stored data are read using Modified Deficit Round Robin (MDRR) approach The transmit memory operates with 240 1 KB blocks and the data is transmitted out via an SPI 4.2 or similar device.

Abstract: Methods and systems for deploying higher-bandwidth networks using lower-bandwidth capable network processing devices. This provides for Parallel Network processing units (PNPU) to work together to process higher bandwidths in networking systems. The methods involve the utilization of several low speed busses to achieve a higher throughput; a CRC generation technique; and improving the performance of such busses using synchronization techniques.
