    摘要: A multivariant, common basis classification method and apparatus for classifying protocol data units in a network switching device is disclosed. The method of classifying a protocol data unit (PDU) in the preferred embodiment includes the steps of generating a first string and a second string with which to characterize a PDU; mapping first and second strings into a first index and second index, respectively, where the first and second indices are selected from a plurality of indices; and selecting an instruction to apply to the PDU by matching the first and second indices. The plurality of strings are commonly generated from the source and destination address in the packet as well as other indicia with which to identify a traffic flow. The instructions specify how to classify, route, switch, or otherwise process the PDU.

    摘要: A method of dynamically enabling MPLS stations and ports using an ARP database is disclosed. The method of dynamically enabling MPLS stations and ports using an ARP database includes augmenting an ARP database with labels distributed via Label Distribution Protocol. The augmented ARP database includes for each ARP entry a list of labels that were advertised to an immediate neighbour. Subsequent use of the ARP database allows for automatic enabling/disabling of MPLS stations and allows labels to be used only on the appropriate ports as advertised to immediate neighbours. The method of dynamically enabling MPLS stations and ports using an ARP database is particularly useful for restricting ports and labels for security purposes, and to automatically provide configuration updates in a timely manner.

    摘要: A takeoff assist device for an air vehicle, such as an unmanned air vehicle is provided. The device features an electric motor and is much less complex and lighter than takeoff assist devices heretofore known. A body member is shaped to fit to a portion of the air vehicle. The body member defines a housing in which the majority of the components are housed, including the electric motor, a motor controller, an electrical power source and a main controller. A propeller is attached to a shaft of the electric motor outside of the housing and rotates with a shaft of the electric motor. In addition, there is a latch mechanism that removeably attaches the body member to the host air vehicle for takeoff, and then is controlled to release from the air vehicle after it is airborne at a desired airspeed and altitude. The electric motor-driven takeoff assist device can launch an air vehicle with minimal auxiliary equipment and can be remotely controlled to launch from a site at which a takeoff ready vehicle can be left for extended periods of time.

    摘要: A method of linking inner and outer MPLS labels to provide enhanced security is disclosed. The method of linking inner and outer MPLS labels to provide enhanced security includes provisioning both an outer label database with reference keys. The outer label database entry provides a key that must be used in conjunction with the inner label database lookup to realize appropriate actions. As the provided key is not publically accessible an additional increment of security is provided. The method of linking inner and outer MPLS labels to provide enhance security is particularly useful blocking malicious packets from being sent into a remote VLAN or VFI.
