Design of buffer structure at core nodes in optical burst switching

Reasonable and effective buffer structures are proposed in core routers/nodes of optical burst switching. Based on the model of burst traffics and their contentions,the basic qualifications for the design of buffer structures are concluded. With these qualifications, buffer and switch integrated structures are proposed; and by conclusion and expansion,the classification rules of buffer structures are also proposed from different angles. The schemes to integrate structures are analyzed and simulated.
