Abstract: One embodiment of the present invention provides a switch. The switch includes a tunnel management module, a packet processor, and a forwarding module. The tunnel management module operates the switch as a tunnel gateway capable of terminating an overlay tunnel. During operation, the packet processor, which is coupled to the tunnel management module, identifies in a data packet a virtual Internet Protocol (IP) address associated with a virtual tunnel gateway. This virtual tunnel gateway is associated with the switch and the data packet is associated with the overlay tunnel. The forwarding module determines an output port for an inner packet in the data packet based on a destination address of the inner packet.

Abstract: One embodiment of the present invention provides a switch. The switch includes a gateway subgroup module, a tunnel management module, and a packet processor. The gateway subgroup module operates the switch in conjunction with a remote switch to form a gateway subgroup. The switch and the remote switch actively operate as tunnel gateways. The tunnel management module maintains a data structure indicating whether a tunnel source subnet is associated with the gateway subgroup. The packet processor decapsulates a tunnel-encapsulated packet in response to a tunnel source subnet of the tunnel-encapsulated packet being associated with the gateway subgroup.

Abstract: Apparatuses, methods, and computer program products for communication are provided. In an aspect, an apparatus for communication may include a processing system configured to receive a frame configured to assign at least member information or position information for one or more identifiers, and receive a data packet associated with a particular identifier and indicating a number of space-time streams for one or more position information. In another aspect, an apparatus for communication may include a processing system configured to transmit a frame configured to assign at least member information or position information for one or more identifiers, and transmit a data packet associated with a particular identifier and indicating a number of space-time streams for one or more position information.

Abstract: A data-synchronization computer program allows many personal portable workstations to wirelessly communicate with a server and to provide updates to an applications database. Each personal portable workstation maintains its own copy of the database with opportunistic updates that occur as the network amongst them allows. Data synchronization object data structures are generated as new data is entered at each personal portable workstation, and these are placed in synch queues for transmission when possible. Each personal portable workstation can continue to operate with its own instance of the applications database and does not depend on instant or continuous network access.

Abstract: Methods, systems, and computer-readable media for searching and concomitantly interfacing with multiple information providers, relevant individuals and communities, and information provided over a network are provided. A single interface including windows is provided. User interactions with the windows of the single interface are monitored, and information from one or more network resources is provided to the single interface based at least in part on the monitored user interactions with the windows.

Abstract: A system is described for processing messages and calls comprising: a plurality of filtering modules to apply a corresponding plurality of rule sets in succession to filter incoming and/or outgoing electronic messages and to apply the highest priority rule from among a plurality of rule sets to calls; and a pre-inbox for temporarily storing the calls and/or electronic messages as each of the plurality of rule sets are applied, the calls and/or electronic messages being removed from the pre-inbox and disposed of only after each of the plurality of rule sets have been applied to the calls and/or electronic messages.

Abstract: An analog lightwave communication system comprises at least two optical transmitters for providing optical information signals at different optical wavelengths. A dense wavelength division multiplexer includes at least two inputs for receiving the optical information signals from the optical transmitters and multiplexes the optical information signals to a composite optical signal at an output. Each input of the dense wavelength division multiplexer comprises at least one optical resonant cavity comprising first and second reflecting materials spaced to permit resonance at a selected wavelength. A fiber optic transmission system coupled to the output of the dense wavelength division multiplexer receives the composite optical signal.

Abstract: A high fidelity, multi-output optical transmission system is configured utilizing a high power continuous wave YAG laser, multiport splitters, and linearized external modulation. An electro-optical modulator design in combination with a c.w. laser, power splits and couplers attains a multi-octave bandwidth transmitter possessing second and third order distortion characteristics of -60 db and a dynamic range >-140 db/Hz. The system includes multiple individually modulated transmitter outputs which effectively provides bandwidth multiplication with full redundancy for increased transmission reliability.
