Abstract: A method for scheduling data bursts from origin to destination nodes of a communication system involves selecting a yet-unscheduled, feasible node pair for scheduling of a burst therebetween; selecting a timeslot from a finite timeslot sequence; scheduling the burst for the selected timeslot; and repeating the preceding steps to exhaustion of unscheduled demand or of feasible node pairs. The feasibility of a node pair is conditioned on the avoidance of collisions with already-scheduled bursts, taking the various origin-to-destination propagation delays into account.

Abstract: In a system and method of optical communication, optical signals are generated in multiple wavelength channels. Each optical signal is passively transported from an origination node of a network to a destination node. The destination node is determined by the signal wavelength. For at least some signals, the passive transport includes transport through a branch point of the network, such that the signal wavelenth determines the output branch through which the signal is routed. In certain embodiments, signals are generated according to a schedule devised to substantially prevent the concurrent arrival, at the same destination node, of signals having the same wavelength but coming from different origination nodes.

Abstract: A method of operating a packet network includes the step of selecting one of a plurality of candidate gateways to connect a multimedia communication session between the packet network and a TDM network. The packet network has a source node of the multimedia communication session, and the TDM network has a destination of the multimedia communication session. The candidate gateways interconnect the packet network and the TDM network. The selecting step includes comparing end-to-end congestions for bearer traffic between the source node and different candidate gateways of the plurality.

Abstract: An apparatus includes a time-domain wavelength-interleaved optical network that connects a plurality of edge nodes. Each of the edge nodes is configured to receive optical communications from others of the edge nodes on an associated wavelength-channel. The number of edge nodes is larger than the number of the wavelength-channels.

Abstract: A VC-merge capable ATM switch allows many routes to be mapped to the same VC label, thereby providing a scalable mapping that can support a large number of edge routers. Such VC merging uses reassembly buffers to insure that cells belonging to different packets intended for the same destination do not interleave with each other. An output-buffered ATM Label Switching Router (ATM LSR) is described that supports VC merging capability while incurring minimal additional buffering overhead compared to non-VC merging approaches.
