Information for the Special Issue
Special Issue Call for Papers:
Today we experience the ubiquitous usage of cloud services provided by worldwide geographically spread data centers. However, due to the long distances between the users and the data storage/computing infrastructure, high latency is experienced by transported traffic, so the QoE is relevantly impacted for some applications. This has lead, two decades ago, to the installation of computation and storage resources closer to the user. More recently, driven by advances in the IoT technologies, distributing data storage/processing by deploying computing and storage resources in proximity of the end users has become a major requirement for latency-sensitive services, leading to a new computation paradigm know as fog computing.
This usage scenario originated the widely referred three-tier architecture of fog computing, which basically unveils the communication interfaces among cloud nodes (data centers), fog nodes (local servers and network devices) and end nodes (networked objects and end-user devices). Looking at this architecture from the transport network perspective, one can observe several communication paradigms, i.e., fog to fog (F2F), fog to cloud (F2C) and cloud to cloud (C2C) communication channels, which require a proper transport infrastructure in order to deliver the required service to the end devices.
The flexibility provided by the elastic optical networks (EON) allows the allocation of the optical network resources tailored to dynamic transmission requests. Furthermore, considering the coherent transmission technology and the sliceable transmission and switching components, EON can provide an efficient usage of spectrum and energy for the data transport, thus being an enabler for the IoT traffic transport, by providing an efficient data transport infrastructure to F2C and C2C computing systems. Moreover, Fiber-Wireless (FiWi) broadband access networks is the key technology that will enable F2F computing systems.
In order to fulfil this task new research has to be conducted focused on the F2F-F2C-C2C communication scenarios, proposing efficient data transport solutions that are aware of the fog computing systems. Moreover, it is also necessary to explore the design of optical nodes and control strategies in a WAN + MAN multi-domain network scenario.
