Abstract:
1. A time-slotted optical burst switching system comprising: an edge node that generates and transmits to a core node a data burst and a burst control packet; and the core node that assigns an output slot for the data burst based on information in the burst control packet before the data burst is transmitted to the core node from the edge node, wherein the data burst is output from the core node using the output slot, wherein the edge node assigns a first slot for the data burst, subsequently generates and transmits to the core node the burst control packet including information on the first slot before the data burst is generated at the edge node if the data burst has a constant bit rate, and substantially simultaneously generates the data burst and the burst control packet if the data burst has a variable bit rate, and wherein the first slot corresponds to an input slot at the core node and is mapped to the output slot at the core node.
