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 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： A network, network devices, and methods are described for packet processing indication. A method includes tunneling a packet from a first network device to a second network device associated with a first checking functionality. The second network device has an address different than an original destination address of the packet. The method also includes return-tunneling the packet from the second network device to the first network device with an indication of whether the packet was processed by the first checking functionality. The method includes tunneling the packet from the first network device to a third network device associated with a second checking functionality in response to the indication being that the packet was not processed by the first checking functionality. The third network device has an address different from the original destination address of the packet.

摘要： Methods of balancing network packet traffic among multiple checking functionalities (CFs) are described. A network has at least one client operatively connected to at least one source switch and multiple available CFs operatively connected to at least one destination switch. Each available CF has predetermined, but possibly different inspection capabilities. A source switch receiving packets from a client inspects each packet and can optionally choose an available CF having at least the minimum necessary inspection capabilities to inspect the particular packet, and tunnel the packet to the chosen CF.
