Abstract
We are developing an optical layer2 switch network that uses both wavelengthdivision multiplexing and timedivision multiplexing technologies for efficient traffic aggregation in metro networks.For efficient traffic aggregation,path bandwidth control is key because it strongly affects bandwidth efficiency.For this paper,we propose a dynamic timeslot allocation method that uses periodic information of difference values of traffic variation.This method can derive nearoptimal allocation with lower computational cost,which enlarges the maximum available network size compared with conventional timeslot allocation methods.Numerical results show that the proposed method enables dynamic path control in 1Knodescale optical layer2 switch network,which leads to costeffective metro networks.
