摘要： A system for forwarding packets. The system has a first node for creating requests that contain a number of filters for specifying packet forwarding criteria. The first node also specifies values for the filters based on a packet to be forwarded. The system also has a second node coupled to the first node and to a number of ports. The second node has at least one table for specifying which of the ports are to receive the packet based on the filter values. The second node determines which of the ports are to receive the packet based on the table information and the filter values.

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： 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： A network, network devices, and methods are described for packet processing. A method includes using logic on a first network device to select a checking functionality based on a number of criteria. The method uses logic on the first network device to select the checking functionality from a list of checking functionalities. The checking functionality is selected for processing packets identified by the first network device. The method also includes using logic on the first network device to configure a tunnel initiation to tunnel packets to a second network device that is associated with the selected checking functionality. The second network device has a destination address different from an original destination address of identified packets.
