  • Flexible multicasting in high-capacity switches
    Patent number: 7911980
    Abstract: In a communication system using multicasting, multicast packets are forwarded through a switch by destination ports after these ports receive the packets. A source node sends the multicast packet to a subset of nodes within the multicast group, which in turn, forward the multicast packet to other subsets of packets within the multicast group that have yet to receive the information. This is continued until all ports within the multicast group have received the information.

  • System for managing telecommunications
    Patent number: 6181703
    Abstract: The invention includes a system for processing telecommunications signaling. Signaling for a call is received into a signaling processor. The signaling processor processes the call and generates new signaling incorporating the processing. The new signaling is transferred to network elements as appropriate. The signaling processor is not coupled to a switch matrix and only communicates with the network elements over signaling links.
