Cost analysis of optical networks with dynamic setup and release of λ-channels
نویسندگان
چکیده
We consider a threshold type control mechanism for dynamic setup/release of λ-channels in optical networks. There are two types of costs for the control mechanism: the setup/release cost and the operation cost. For such a control mechanism, there is a corresponding Markov model with high complexity. By state aggregation, we are able to identify a semi-Markov process that is simpler to analyze. Based on the semi-Markov process, we derive the average cost formula for the threshold type control mechanism and carry out several numerical examples to find the optimal thresholds that minimize the average cost. Keywords—lightpath, Semi-Markov process.

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...
