Abstract: There is provided a system and method for prioritizing session initiation protocol (“SIP”) messages. More specifically, in one embodiment, there is provided a method of prioritizing SIP messages in a network, the method comprising receiving SIP messages in a first order from one or more other servers of the network, wherein each of the received SIP messages comprises one or more priority indicators, scheduling the received SIP messages into a second order based on one or more of the priority indicators, and processing the scheduled SIP messages in the second order.

Abstract: A system and method for reducing switching overhead in a communication network and a web-based server incorporating the system or the method. In one embodiment, the system includes: (1) an optimization engine configured to receive input data describing trunks, switches and traffic demands in at least a portion of the communication network and arrange connections between the trunks and switches such that the traffic demands are satisfied and such that a switch load or cost is reduced and (2) a report generator associated with the optimization engine and configured to produce a report containing a modified configuration having the reduced switch load or cost.

Abstract: Techniques and systems for design of optical switch arrays so as to minimize power requirements are described. A design system includes a computer system hosting a design program. The design program receives parameters for the switch array, including a number N of outputs required, and either a maximum number L of stages allowed or maximum and average power requirements allowed. If power requirements are used as parameters, the design program uses N and the power requirements to compute the value of L. The design program then constructs a minimum power sequence of L switches or N switches, whichever is less. If N is less than L+1, N outputs are present and the array is complete. If N is greater than L+1, the design program then adds switches one at a time to the minimum power switch path of the array, until the array provides N outputs.
