GATEWAY BROADCOM LAN DRIVER



The HW accelerators are dedicated hardware processing components designed to increase the packet processor 's performance by speeding up time consuming tasks.

These dedicated processing components include at least one of a lookup table, a scheduler, a register file, a direct memory access DMAGateway Broadcom LAN classifier, a board bus interface, an IP checksum calculator, an external memory lookup engine, Semaphores for synchronization between the two packet processorsand general purpose timers for different time counting tasks, such as rate limiting. The CRC accelerator operates off line on data stored in data memory The scheduler receives requests from the different request generators and determines the next thread number when a context switch is triggered.

The next thread is selected according to a predefined priority policy. The DMA accelerator is responsible for data transfer from and to the data memory and an external memory. Configuration registers can be read and written by the microprocessor of FIG. The classifier accelerator parses a packet's header and generates a data structure that includes useful information in the packet's header.

The data structure is in a format that allows a core processor a fast access to a packet's fields required for the processing. The classifier also determines based on a packet's header which Gateway Broadcom LAN gateway processing tasks are required. The packet is processed by one of the core processors A or B according to the classification.

The security engine provides a mechanism for IP security IPsec processing by implementing HW accelerators for decrypting, encrypting and authentication of packets. Gateway Broadcom LAN S, incoming data fragments are assembled in the external memory Data fragments are sent to the external memory through the DMA engine While assembling the data fragments, validity checks are performed on the assembled packet.

These checks include at least CRC and length checks. At S, it is determined if the assembled packet is valid, and if so execution continues with S, otherwise, at S, the packet is removed from the board bus adapter and execution ends. At S, the Gateway Broadcom LAN packet now Gateway Broadcom LAN in the external memory is processed by one of the packet processors A or B. This step includes assigning a packet description DS to the packet, classifying the packets according to their header, and a performing a residential gateway processing task according to the classification's results.

The residential processing task may include, for example, switching a packet, decrypting a packet, mapping a packet to another address, queuing a packet, and so on.

It is appreciated Gateway Broadcom LAN these tasks are traditionally performed by a residential gateway. Once the packet processing is completed, at S the packet descriptor is linked with an output queue associated with Gateway Broadcom LAN destination Ethernet MAC adapter Once the packet processor writes the packet descriptor to the output queue, a new incoming packet can be handled by the processor At S the destination Ethernet MAC adapter retrieves data chunks from the external memory using the packet description.

The access to the external memory is through a respective broad bus handler and the DMA engine At S upon reception of the entire packet, at the Ethernet MAC adapter the packet is being transmitted to the subscriber device connected to the adapter It should be noted that each packet Gateway Broadcom LAN supports a pipeline architecture, thus at any specific time more than one packet is being processes. In addition, a packet processor does not require completing the processing of a packet before starting to process the next packet. At S, the data packet is saved in the external memory During the transfer of the data packet to the external memoryvalidity checks are performed on the assembled packet. At S, it is determined if the incoming packet is valid, and if so execution continues with S, otherwise, at S, the data packet is deleted from the external memory At S, the data packet now stored in the external memory is processed by one of the packet processors This step includes assigning a packet description DS to the packet, classifying the packet according to its header, determining which residential gateway processing task is required, and performing the processing task according to the classification's results.

A residential gateway processing task may be, for example, routing a packet, switching a packet, encrypting a packet, mapping a packet, or queuing a packet. Once the packet processing is completed, at S Gateway Broadcom LAN packet descriptor is linked with an output queue which belongs to a specific T-CONT.
