The number of applications running in the cloud has dramatically increased in the past decade as well as the number of users accessing them. Data centres resources, architectures and conditions define the performance of the applications running on them. One of the main measures of the network efficiency is the latency, which can have a huge effect on resources utilisation, power consumption and the overall performance. In this paper, the performance of a fog network is evaluated by measuring the latency while running a facial recognition software. The network consists of two processing cells, a core network and a PON cell. The results show how network latency is affected by running the facial recognition software in the end-to-end network setup introduced in this paper.

“…Over the past few decades, there has been a growing trend towards the development of energy-efficient core and access communication networks 7, . Additionally, there is considerable attention dedicated to devising energy-efficient solutions for data centre designs, as evidenced by the research spanning these areas [39][40][41][42][43][44][45][46][47][48] . The work in this paper aims to reduce the power consumption of the commodity networking hardware used by introducing novel ways of interconnecting and manging servers, accelerators, storage and interfaces in small processing cells (cloudlets).…”

In recent years, traffic in Information and Communication Technologies (ICT) networks has shown growth of 30% to 40% every year, where server to server communication accounts for 70% of the global IP traffic. This could potentially lead to an increase in traffic by factors of 30x and 1000x in 10 years and 20 years respectively. ICT networks are responsible for 2% of the global emissions with carbon footprint comparable to the aviation industry. Data rates have grown rapidly in the past decade from 1Gb/s server to server communications to 100 Gb/s with plans to increase to 400 Gb/s and 800 Gb/s within this decade. This increase has led to the need for more sustainable solutions in Data centres (clouds) and processing at the edge of communication networks (fog). This paper introduces novel cellular optical interconnection networks that enable energy efficient, scalable, resilient and low latency server to server communications. The proposed optical interconnection network linking servers uses new cellular passive optical network (CPON) architectures. The passive optical networking results in 80% power saving in the networking inside clouds and fog compared to state-of-the-art electronic Spine and Leaf server interconnections and also 85% reduction in latency. The reduction in carbon emissions due to the adoption of CPON technology in cloud and fog networks globally can lead to the elimination of the emissions due to homes in a country the size of Greece or Belgium.

The use of Passive Optical Networks (PONs) in modern and future data centers can provide energy efficiency, high capacity, low cost, scalability, and elasticity. This paper introduces a passive optical network design with 2-tier cascaded Arrayed Waveguide Grating Routers (AWGRs) to connect groups of racks (i.e. cells) within a data center. This design employs a Software-Defined Networking (SDN) controller to manage the routing and assignment of the networking resource while introducing multiple paths between any two cells to improve routing, load balancing and resilience. We provide benchmarking results for the power consumption to compare the energy efficiency of this design to state-of-the-art data centers. The results indicate that the cascaded AWGRs architecture can achieve up to 43% saving in the networking power consumption compared to a Fat-Tree data center architecture.
