Séminaire R3S présenté par Francesco Bronzino le 14 mai 2018 à 11h30 en G09, à Télécom SudParis (Evry)

Titre: Towards a Service Oriented Internet Experience: New Approaches to Service Enhancement

Résumé:
This talk introduces the audience to different approaches aimed at supporting current and future advanced network services, enabling higher degrees of performance and easiness of deployment. In the first part of the talk, I will present a new approach to networking, centering around the architectural concept of Named-Object based networking and the abstraction power that lies behind it. As an example of its potential, an analysis of how distributed cloud services can be supported in the proposed architecture is given. Exploiting a novel framework that provides a clean and simple way to define and deploy a Virtual Network at Layer 3, the Named-Object based architecture can enable finer control to service traffic management by allowing network routing decisions to be made with awareness of application parameters such as cloud server workload.
The second part of the talk then focuses on the development of techniques aimed at dissecting and optimizing current network services exploiting fined grained information extracted from network traffic. This concept is exemplified by a new lightweight system that running at the home network gateway analyzes traffic generated by DASH on-demand and live video streams. By detecting key video QoS metrics and pinpointing where potential root causes hampering the streaming process might be located, the system can provide a key overview on how to address streams instability in order to improve the final quality of the visualized video.

Biographie:
Francesco Bronzino is a Post-Doctoral research fellow in the MiMove group at Inria, Paris, where he is currently working on developing network systems aimed at supporting and enhancing network services from home and access networks. Before joining Inria, he received his Ph.D. in Electrical and Computer Engineering from WINLAB (Wireless Information Network Lab) at Rutgers University, working on designing and developing name based services for future Internet and mobile network architectures. His research interests broadly focus on the Internet infrastructure and the services that populate it, with particular interest in understanding systems, protocols and new technologies that can enhance service development and final performance.
