摘要： A network device is provided which can include logic associated with the operations of a data communications protocol stack. The logic can operate to receive a packet to the network device and apply a first error checking technique, having a first modification complexity, to a header of the packet. The logic can apply a second error checking technique, having a second modification complexity that is greater than the first modification complexity, to a body of the packet. A first verification key can be provided to a first header associated with the packet and a second verification key, having a different modification complexity from the first verification key, can be provided for a second header associated with the packet.

摘要： Network devices and methods are provided involving a support chip in association with network chips. One embodiment includes a network device having a processor, a high speed interconnect, and a number of network chips coupled to one another through the high speed interconnect. The number of network chips include a conduit port which can be selectively chosen to exchange packets, received to the number of network chips, with the processor. The support chip is coupled to the number of network chips in association with selecting a conduit port on one of the number of network chips to exchange packets with the processor.

摘要： Systems, methods, and devices are provided for moving packets on a network device. One method includes receiving packets to a number of network chips, the number of network chips having a conduit port which can be selectively chosen to exchange packets with a processor responsible for processing packets. The method includes adding data for additional functionality to certain packets. Adding data includes encapsulating the certain packets to maintain an appearance of a certain packet format.

摘要： A method for testing a network device having modules for receiving and sending data packets in a network includes generating in the network device at least one internal data structure associated with a data packet received by the network device from the network. A predefined action on the network device is then preformed responsive to the internal data structure indicating that the data packet satisfies a predefined condition.

摘要： Buffer management in a network device. A new data packet is received at a packet buffer queue of the network switch, wherein the new data packet is a portion of a burst block. If the packet buffer queue is full, a data packet from within the packet buffer queue that is not a last sequential data packet of a burst block is dropped.

摘要： A method for allocating a resource among a plurality of consumers of the resource is described herein. For each consumer of the plurality of consumers, a configurable weight associated with the consumer is determined. For each consumer of the plurality of consumers, credits assigned to the consumer at a first interval of a plurality of variable intervals are determined. The credits may be assigned in proportion to the configurable weight associated with the consumer. A consumer is selected for servicing based on the credits of the consumer. The selected consumer is serviced.
