Analysis of Assembling Algorithm in Optical Burst Switching Networks under Multiple Objective Restrictions

The restriction of the network performance such as the processing delay of control plane, the utilization probability and the burst collision probability on the assembling algorithm is analyzed and studied. The results verify that the data plane is more sensitive than the control plane with the assembling algorithm of edge nodes. The network with core nodes without wavelength converter has no valid assembling threshold under the multiple objective restrictions. When implemented with a general optical exchange connector and under the desired burst collision ratio 10-4, the core node needs at least thirty wavelength converters per output fiber link to satisfy the performance requirement.
