With the increase in big data applications, it has become the need of the hour to handle data efficiently to handle the growing traffic in the data centers. The popular mechanism is parallel processing using commodity hardware hence it is becoming an interesting research topic to explore new architectures which have high performance, but with an increase in data sizes the architecture has to expand which increases the cabling complexity. Hence the study of Free Space Optical (FSO) communication for the data centers is gaining more importance now than ever. We proposed square OWCELL topology which is a new free space optical (FSO) architecture and was accepted in IEEE-ICC . With a view of competing with existing Fat-tree architecture, we are also exploring the usage of hybrid switching over the OCS switching. We also modify a flow level simulator which helps reduce the complexity of simulation by considering the study of flows instead of packets. In this tool, we calculate the parameters of flows accepted, flows rejected, flows for which path cannot be found, total flows and their percentages. The Hybrid performs at par or better most of the times as compared to OCS switching by about 3-8% on the variation of buffer sizes, the number of servers in the network and the congestion.
