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: 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.
