  • Patent number: 6804255
    Abstract: A system and method for implementing channel scheduling algorithms in an optical router wherein a scheduler operates pursuant to an algorithm and is capable of determining the availability of outbound data channels capable of carrying a data packet of duration B. The scheduler is further capable of selecting one channel from available data channels and assigning the data packet to the selected channel. The scheduler then updates state information of the selected data channel, but if no data channel is available to carry the data packet the data packet is dropped.

  • Patent number: 6721315
    Abstract: A control architecture for an optical burst-switched network includes an electronic ingress edge router, a switch control unit at each hop, and an electronic egress edge router. The electronic ingress edge router assembles multiple data packets into a burst. The switch control units at each hop configure the optical switching matrix to switch the burst through the optical burst-switched network. Finally, the electronic egress edge router receives the burst from the optical burst-switched network and disassembles the burst into multiple data packets.

  • Patent number: 6671256
    Abstract: The present invention provides a system and method for reserving data channels in an optical burst-switched network. A data channel (or a multiple of data channels) along an optical path in an optical burst-switched network is reserved by first transmitting a data channel reservation request from an electronic ingress edge router to a reservation termination node. Next, the data channel reservation request is processed at all nodes along the optical path, including the reservation termination node. A data channel reservation acknowledgement is then transmitted from the reservation termination node to the electronic ingress edge router. Finally, the data channel path is reserved once an initial burst(s) which contains a reserve data channel bit reaches the reservation termination node.

  • Patent number: 6661789
    Abstract: A system and method for assembling multiple multicast data packets into a multicast burst according to multiple multicast burstification classes and switching the multicast burst through an optical burst switched network. To switch multicast data packets through an optical burst switched network according to the present invention, multicast data packets are first assembled into a multicast burst at an electronic ingress edge router according to a plurality of multicast burstification classes. The multicast burst is then switched through the optical burst-switched network to the destined electronic egress edge routers, disassembled back into multicast data packets and transmitted to multiple destinations.
