摘要： Techniques are described for detecting corruption of buffer pointers passed between a local processor and a remote processor on a network device. For example, the first processor, which may be a memory controller, receives and stores packets within memory. A second processor, such as a host processor for the network device, is coupled to the first processor by a bus. The first processor communicates a memory pointer associated with an a given packet to the second processor for processing of the packet, and maintains a backup copy of the memory pointer. Upon receiving the memory pointer back from the second processor, the first processor compares at least a portion of the memory pointer received from the second processor with an equivalent portion of the copy of the memory pointer to determine whether the received memory pointer has been corrupted.

摘要： A network device includes a receiver component that generates flow control information. The network device also includes a transmitter component that receives a packet for forwarding to the receiver component, receives flow control data for the packet from the receiver component, and provides the packet and the flow control data for the packet to a fabric component. The fabric component performs a congestion management operation for the packet, and forwards the packet to the receiver component based on the flow control data and results of the congestion management operation.

摘要： A system and method for intrusion detection and prevention processing are described. Spin state information associated with a signature may be prefetched by a network device having one or more buffers. The spin state information may be stored by the buffer. Context data may be searched using the spin state information stored by the buffer.

摘要： A network device receives traffic associated with a network of intermediate network devices and user devices, classifies the received traffic, and allocates the classified traffic to traffic queues. The network device also schedules particular queued traffic, provided in the traffic queues and bound for particular intermediate network devices, using a hybrid weighted round robin (WRR) scheduler where the hybrid WRR scheduler schedules the particular queued traffic according to one of a 1-level WRR schedule, a 1.5 level WRR schedule, or a 2-level WRR schedule. The network device further provides the particular queued traffic to the particular intermediate network devices based on the scheduling of the hybrid WRR scheduler.
