We proposed a novel 2x2 all optical packet switching router architecture supporting asynchronous variable-length packet. In order to deal with the contention problem we adopt for wavelength conversion strategy. A proof of concept through Optiwave simulation is validated. We have showing that the contending packet is detected and forwarded according FIFO (First In First Out) strategy at a different wavelength. Error-free functionality is achieved for high bit rates (up to 100 Gbps).
In this paper two all optical packet forwarding architectures based on non linear effect in semiconductor optical amplifier in Mach-Zehnder configuration SOA-MZI are studied. The first architecture consist in combing flip flop functionality with the AND logic functionality in the same unit. Error free operation at 40 Gbps for two cascaded nodes is achieved. In the second architecture two separated units namely the flip flop and the AND logic gate are used. 100 Gbps bit rate is reached. At 40 Gbps error free operation is achieved for three cascaded nodes.
We proposed a novel 2×2 all optical packet switching router architecture supporting asynchronous, labelled and variablelength packet. A proof of concept through Matlab Simulink simulation is validated. Then we discussed the three possible scenarios to demonstrate the contention resolution technique based on deflection routing. We have showing that the contending packet is detected and forwarded according FIFO (First In First Out) strategy to another output.
