A network (4) includes optical routers (19), which route information in fibers (10). Each fiber carries a plurality of data channels (16), carrying data in data bursts (28) and a control channel, carrying control information in burst header packets (32). A burst header packet includes routing information for an associated data burst (28) and precedes its associated data burst. Information on the data channels and control channel is organized in synchronized slots. Multiple burst header packets occupy portions of a slot, referred to as micro-slots. When the burst header packets are received, an egress processor (52) schedules the routing of their associated bursts. The egress processor (52) determines a time at which a data burst can be scheduled for passing through an optical matrix (40) to the desired output channel group (the burst can be delayed via fiber delay lines (46) if necessary).
A method of modeling communications traffic at a router in an optical burst switched network, wherein data bursts are received by the router over a first set of plurality of optical transmission lines and are switched to a second set of optical transmission lines, wherein the data bursts are communicated over said first and second sets of optical transmission lines over multiple channels using synchronous fixed length slots, each burst occupying one or more slots in a channel, comprising the steps of:
A router for use in an optical burst switched network, comprising:
