SEMPER: A Stateless Traffic Engineering Solution for WAN based on MP-TCP

11 May

In-house Presentation

Enterprise Networking has a strong set of requirements in terms of resiliency, reliability and resources usage. With current approaches being based on monolithic and expensive infrastructures using dedicated overlay links, providers are moving to more economical hybrid solutions that encompass private dedicated links with public/regular Internet connections. However, these usually rely on complex, hardware-dependent and/or proprietary Traffic Engineering (TE) solutions, which are computationally costly, in particular for the forwarding nodes. In this paper, we propose SEMPER: a lightweight TE solution based on MP-TCP that, in contrast to other TE solutions, moves the complexity to the endpoints of the connection, and relieves the forwarding elements from complex operations or even maintaining state. As our evaluation shows, SEMPER efficiently makes use of all available paths between the endpoints while maintaining fairness, and properly adapts to variations on the available capacity.

About Ginés García Avilés

Ginés García Avilés is a PhD student at IMDEA Networks Institute. He obtained his B.Sc. in Computer Science specializing in Software Engineering from the University of Murcia, Spain, in 2016. Then, He obtained the M.Sc. in Telematics Engineering at the University Carlos III of Madrid, Spain, in 2017. His final project of the M.Sc. dealt with the definition and implementation of a Stateless Traffic Engineering solution for WAN based on Multipath-TCP. His research topics are SDN, NFV, SDR and mobile networks. Ginés García is now focusing on the definition and implementation of RAN and CORE Network components, using SDN and NFV paradigms as the enablers of new functionalities.
