Performance Analysis of Hybrid Electro-Optic Architecture for Next Generation Network

Abstract

In this paper our objective is to develop a hybrid electro-optic network model that can provide a significant impact for the next generation networks. Optical network provides very high bandwidth and minimum loss. But the optical switch suffers high latency (10 ms) at the time of switch reconfiguration and hence not suitable to handle bursty traffic efficiently. In our proposed model the traffics are classified into two categories: mouse traffic and elephant traffic. As per the traffic category the network path is selected. For mouse traffic electrical domain is used and for elephant traffic optical path is used. The detailed network architecture and its functions are elaborately described in this paper. The performance of the network is analyzed in NS2 environment and is focused on physical layer parameters in terms of cumulative network delay, consumed bandwidth and packet loss. A comparative analysis is done for the existing network model and our proposed model. Simulation results indicate that our proposed model has a considerable impact for future realistic network.
