24th Conference on Innovation in Clouds, Internet and Networks


The theme of the conference for 2021 is the melding of network and computing services that is clearly demonstrated by the increasing softwarization of the network services in the the core and the access networks, the rise of computing in the network and the growth of cognition in networking for management and control as well as for value added services at the edge and in the data center. Several innovations are impacting the ongoing transformations toward the network of the future and the evolution of cloud services.  More and more the network fabric itself emcompasses functionality usually associated with computing as increased intelligence and cognition are necessary to address emerging requirements of distributed services, automation and network reliability. At the same time, more and more, the cloud is extending to the edge adding a number of heterogeneous networked subsystems to the Internet with a variety of requirements that further highlight the need for novel architectures, e.g., IoT systems, augmented and virtual reality and service delivery platforms. The result is the networking and computing systems becoming one, melding, as a distributed cloud/edge continuum with cognition and intelligence for emerging services. This “Computing and Networking as a Service” is the paradigm that will be central to the deployment of immersive services in many different sectors, such as e-health, self-driving cars, industrial networks, agriculture and cloud robotics.


Le 2 mars de 16h40 à 17h00 : Marion Ficher de RENATER va présenter une étude sur l’évaluation de l’empreinte carbone de la transmission de données sur un réseau


Assessing the carbon footprint of the data transmission on a backbone network 

The goal of this paper is to assess the carbon footprint of data transmission on a network via a simplified Life Cycle Assessment (LCA) methodology. We did direct measures of the electricity consumption and the IP traffic of most of the devices required for the transmission between two sites on the backbone network. Our case study aims to compare two conditions for the data transmission, varying infrastructure density and network activity. The results for the peak day are 1.3 gCO2e/GB for the transmission across France and 0.6 gCO2e/GB for a more local transmission, and respectively 1.9 gCO2e/GB and 1 gCO2e/GB for an off-peak day.


L'objectif de ce document est d'évaluer l'empreinte carbone de la transmission de données sur un réseau par le biais d'une méthodologie simplifiée d'analyse du cycle de vie (ACV). Nous avons mesuré directement la consommation d'électricité et le trafic IP de la plupart des appareils nécessaires à la transmission entre deux sites sur le réseau de base. Notre étude de cas vise à comparer deux conditions de transmission des données, à savoir la densité variable de l'infrastructure et l'activité du réseau. Les résultats pour le jour de pointe sont de 1,3 gCO2e/GB pour la transmission à travers la France et de 0,6 gCO2e/GB pour une transmission plus locale, et respectivement de 1,9 gCO2e/GB et 1 gCO2e/GB pour un jour hors pointe.
