1. A Universal-Transfer-Mode network (UTM network), comprising a plurality of Universal-Transfer-Mode modules (UTM modules) interconnected by a passive core, said passive core consisting of a plurality of optical cross connectors through which routes are established among said UTM modules, wherein each of said UTM modules includes a plurality of ports that accept data in Universal-Transfer-Mode format (UTM ports) and optionally includes other ports selected from a group comprising:

  • (a) STM ports;

    (b) ATM ports;

    (c) Frame relay ports; and

    (d) IP ports; and

    wherein each of said UTM ports is operable to process UTM packets according to a Universal-Transfer-Mode protocol (UTM protocol), and each of said UTM ports includes (a) a hysteresis control circuit operable to determine data transfer allocations; and

    (b) a scheduler of data packets of variable sizes said scheduler operable to control the rate of data transfer at the egress of each UTM port.
