A global positioning system (GPS) is used to detect locations (dynamic locations) associated with meeting participants and the proximity between participants is used to create one or more location clusters. Next, the availability of suitable meeting locations (static locations) are identified and an optimum meeting location, given the participant clusters and their proximity to the available meeting locations, is determined. Additionally, the center of mass associated with each of the clusters is also used to determine optimal meeting locations. Lastly, participants are notified regarding the optimized location for the meeting.

An architecture and related systems for improving the performance of non-blocking data switching systems. In one embodiment, a switching system includes an optical switching core coupled to a plurality of edge units, each of which has a set of ingress ports and a set of egress ports. The switching system also contains a scheduler that maintains two non-blocking data transfer schedules, only one of which is active at a time. Data is transferred through the switching system according to the active schedule. The scheduler monitors the sufficiency of data transferred according to the active schedule and, if the currently active schedule is insufficient, the scheduler recomputes the alternate schedule based on demand data received from the edges / ports and activates the alternate schedule. A timing mechanism is employed to ensure that the changeover to the alternate schedule is essentially simultaneous among the components of the system.
