Free Space Optical Communication (FSO) is a promising technology to address wired Data Center Network (DCN) challenges like power consumption, low scalability and flexibility, congestion and cabling. Scholars have developed indirect line-of-sight (LoS) FSO schemes by reflecting the FSO beams via switchable mirrors. These schemes have introduced extra overhead delay to establish indirect LoS links, defined herein as the rack-to-rack FSO link setup process. The purpose of this work is to study and model this setup process with the consideration of the DC workloads. We found that the process involves a sequence of i.i.d random variables that contribute differently to its delay. Also, the process shows a statistical characteristic close to M/M/K. However, the number of FSO links, K, is random with time, which necessitates careful modeling. Finally, the PDF of the process total response time is close to the hypoexponential distribution, and it maintains its main characteristics even with different distributions for the service time.

An Efficient Wireless Control Plane for Software Defined Networking in Data Center Networks

Software defined networking (SDN) has re-defined the way data center networks are deployed and functioned. The ability to separate the control plane and data plane have led to the simpler design and easier management. In SDN, the data plane and control plane are separately managed, so building an additional wired network to connect the control plane and the data plane can lead to a high cabling complexity. This paper proposes an end-to-end end wireless control plane architecture for SDN-enabled data center networks. In the proposed architecture, the switches form clusters that are wirelessly connected to the controller via access points (APs) and relay nodes (RNs). The switches use the 2.4/5-GHz band to connect with the APs, whereas the APs and the RNs are connected to the controller using the 60-GHz band. We have presented an analytical model to derive achievable data rates in our wireless control plane. We have also proposed two algorithms that allow an optimal number of a cluster size of the switches to be connected with the Controller via minimum number to APs/RNs such that the control traffic demands of the switches is guaranteed in interference constrained environment. Through extensive simulations, the results of our proposed architecture show that the cabling complexity in the control plane is reduced to zero and additional switches may be easily added in SDN data center. Thus, a pure wireless solution for building a control plane in a data center network is feasible.INDEX TERMS Data center networks, software-defined networks, wireless control plane.
