Designing green network architectures using the ten commandments for a mature ecosystem

Abstract

The Climate Group notes that energy consumption by ICT activities represented 2 % of global human activity in 2009 [1]. ICT is therefore a sector contributing both to natural resource depletion and to greenhouse gas emission. Moreover, ICT generates considerable quantities of electronic waste, it emits radio waves (including GSM and WiFi) that can adversely affect human and animal health, and it can have an impact on the natural beauty of the landscape (e.g. antennas). A new challenge for ICT engineers is therefore to be able to design ICT more efficiently by considering environmental constraints. In the ecology domain, J. M. Benyus' book "Biomimicry" [2] proposed ten commandments for mature ecosystems. The objective of this paper is to apply these commandments to ICT, by focusing on green network architecture design. The main developments in this research are the proposed relationships between the ten commandments and the networking domain and metrics for assessing both the project-system and the system-of-interest when designing green network architectures.

Using ICT Energy Consumption for Monitoring ICT Usage in an Enterprise

“…The study by Drouant et al [8] proposes models that gives a global overview of the impact that the network and the ICT equipment is having on the environment, developing the following equation:…”

Measurements and Sustainability

“…From the previous analysis, the objective is now to define three main metrics, named Measures of Performances (MoP) in the context of system engineering, enabling to consider in the development of Green ICT application the recyclability, the energy consumption and carbon emission Obviously, these MoP are first proposals (Drouant N. et al, 2014) and should be refined and completed by other ones in order to take into account all kinds of pollutions and resource scarcity issues. The table 1 provides all the notations used in the different equations.…”

An Informational Model as a Guideline to Design Sustainable Green SLA (GSLA)

“…The health effects of radio waves were also studied and most of these studies found that the EMF (electromagnetic field) effects on the human body are not only depends on their field level but on their frequency ranges and energy [8,11]. All studies claim that the unique non controversial effect of non ionizing EMF is thermal [11].…”

“…The health effects of radio waves were also studied and most of these studies found that the EMF (electromagnetic field) effects on the human body are not only depends on their field level but on their frequency ranges and energy [8,11]. All studies claim that the unique non controversial effect of non ionizing EMF is thermal [11]. To avoid this electromagnetic effect, the government of each country defines maximum level of EMF generated by wireless antenna and their maximum Specific Absorption Rate (SAR) value [8].…”

“…This is a very complex indicator and need to be sub divide as reuse, refurbish, sub-cycling and up cycling. According to [8,11], the Recyclability Rate of an equipment ranges from 0 to 1. Again, at each stage of recycling, it needs to be considers the CUE, GEC, Energy Cost (Table I) Toxic Material Information-Electric and Electronic products contain several toxic materials such as Beryllium, Cadmium, Lead, and Mercury etc.…”
