A buffering architecture based-on traffic load selection scheduling for optical packet switching networks
Huanlin Liu, Junyu Pang · 2009
An optical buffering architecture based-on traffic load selection was put forward for optical packet switching networks in the paper. For improving the limited fiber delay lines utilization, the segment shared buffering mechanism be used to configure the output fiber delay lines and the output/feedback shared buffer module configuration using degenerate model. When the traffic load is larger than threshold value, the output/feedback buffer module is worked on the feedback buffer mode. Otherwise, the output/feedback module is worked on the output buffer mode. So, the buffer mode can be selected flexible according to the traffic load. The analysis and simulation results show that this buffer architecture can decrease packet loss probability effectively and achieve reasonable average packet delay.
