“…Figure 1 shows that the Optical-Fog layer [7] uses ONUs in the middleware of the cloud and IoT layer. In a typical PON channel with multiple OLTs, each OLT is connected with multiple ONUs [8]. The Optical-Fog layer is designed by using their residual processing, storage, and interconnection capabilities.…”

This chapter is a study of exploring the role of the optical network in the cloud/ fog computing environment. With the growing network issues, unified and cost-effective computing services and efficient utilization of optical resources are required for building smart applications. Fog computing provides the foundation platform for implementing cyber-physical system (CPS) applications which require ultra-low latency. Also, the digital revolution of fog/cloud computing using optical resources has upgraded the education system by intertwined VR using the fog nodes. Presently, the current technologies face many challenges such as ultra-low delay, optimum bandwidth, and minimum energy consumption to promote virtual reality (VR)-based and electroencephalogram (EEG)-based gaming applications. Ultra-low delay, optimum bandwidth, and minimum energy consumption. Therefore, an Optical-Fog layer is introduced to provide a novel, secure, highly distributed, and ultra-dense fog computing infrastructure. Also, for optimum utilization of optical resources, a novel concept of OpticalFogNode is introduced that provides computation and storage capabilities at the Optical-Fog layer in the software defined networking (SDN)-based optical network. It efficiently facilitates the dynamic deployment of new distributed SDN-based OpticalFogNode which supports low-latency services with minimum energy as well as bandwidth usage. Therefore, an EEG-based VR framework is also introduced that uses the resources of the optical network in the cloud/fog computing environment.

“…The same principle can be used for creating well-protected inter-building PON networks in large office or business centres as local backbone networks with enhanced resilience. Similarly, the application of proposed ring and bus topologies for well-protected small network cloud solutions containing critical databases and servers is possible [46]. Another application of a presented ring or bus topology is a local protected network located inside the larger PON infrastructure.…”

This paper is focused on passive optical networks (PONs), especially on increasing their network resilience. Because the most critical components in PONs are usually the optical line termination unit (OLT) and optical fibres connecting all network nodes, the main motivation presented within this paper is to improve the resistance of PON against critical failures of OLT and optical fibres between them. Both presented solutions are based on using dual OLT units and the application of asymmetric splitters in order to balance the attenuation and optical signal levels throughout the entire network, while the main innovation consists in the application of ring and bus topologies. Both bus and ring topologies can be formed easily using only passive splitters with optimum splitting ratios; therefore, no active components are necessary. The next advantage is the opportunity of placing both OLT units in physically diverse location, thus increasing the overall network resilience. Moreover, the presented idea with a bus topology offers an additional resistance against the failures of optical fibres connecting the splitters as well. Because the application of asymmetric passive splitters in both solutions is necessary in order to optimize the optical signal levels in the entire network, the mathematical models for calculating of their optimum splitting ratios are included. To verify the functionality of both topologies and their protection mechanisms, complex simulations were performed and are presented in this article as well.

“…In [27], the challenges associated with controlling the routing is addressed by facilitating the capabilities of Software Defined Networking (SDN) to control the optical layer [29]. The energy efficiency and cost effectiveness of PON equipment suggest the use of PON-based DCN not only in massive cloud data centers [23], but also in existing PONs at the edge of the network for fog computing as considered in [30]- [32]. Small scale PON-based DCNs can be attached in the access network for extended processing capabilities.…”

In this paper, we utilize Mixed Integer Linear Programming (MILP) models to compare the energy efficiency and performance of a server-centric Passive Optical Networks (PON)-based data centers design with different data centers networking topologies for the use in fog computing. For representative MapReduce workloads, completion time results indicate that the server-centric PON-based design achieves 67% reduction in the energy consumption compared to DCell with equivalent performance.
