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.

摘要： A network, network devices, and methods are described for marked packet forwarding. A network device includes a network chip having a number of network ports for receiving and transmitting packets. The network chip includes logic to decapsulate a packet received from a tunnel, mark the packet with a handle associated with an originating network device of the packet using information from an encapsulation header, and forward the marked packet to a checking functionality having a destination address different from an original destination address of the packet.

摘要： Network devices, systems, and methods are provided for packet processing. One network device includes a network chip including logic and a number of network ports for the device for receiving and transmitting packets therefrom. The logic is operable to group a number of ports into a membership group based on a criteria, and define a filter index in association with a network packet to indicate the membership group.

摘要： System and methods for metering output packet traffic at network devices. Ingress packet lookups are employed in combination with egress packet meters, which can be arranged in parallel fashion, and used to meter traffic across multiple blades of a switch chassis. Also, egress packet traffic metering is accomplished while matching complex ingress rules without additional egress packet processing. The system has a first node for creating requests that contain a number of filter indicies for specifying packet forwarding criteria. The first node also specifies values for the filter and meter indicies 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, and at least one table for accounting for egress traffic bandwidth.
