Panel I: What is next for Inter Data Center Interconnects (DCIs)?

Tuesday, 08 June 12:15 – 13:45

Moderator: Loukas Paraschis, Infinera, USA

Panel Description:

The networks interconnecting datacenters, commonly referred to as DCI, has grown more than any other transport infrastructure in the last decade, and is projected to grow by several orders of magnitude in the coming years. Consequently, the economics associated with this growth have motivated the development of 1) dedicated DCI networks which account for some of the most spectrally efficient fiber deployments globally, and 2) a new class of purpose-built DCI transport systems. DCIs has also pioneered in optical transport the adoption of software innovations in automation, programmability, management abstraction, and control-plane disaggregation, as well as the introduction of the associated open transport architectures. This panel of industry leaders will discuss the extent to which these innovations have been successful in current and future DCI networks, and debate the important emerging innovations.

Michael Strunz-Kroll, euNetworks, Germany​
​Presentation Title: OpenDCI from the Ground Up: Scaling Disaggregated Bandwidth Infrastructure Solutions in the European Market

Abstract: Staying successful in the highly segmented European market with newcomer DC operators, traditional telco’s, ISP’s, various sized established players and big content providers means innovation needs to happen across many layers. This presentation will share an insight from a network operator perspective into the latest trends around increasing network density and diversity, deployment of the newest fibre type technologies as well as offering disaggregated open optical solutions and delivering process automation.

Michael Strunz-Kroll is Head of Architecture and Engineering at euNetworks, responsible for the strategic technology and platform decisions, its introduction into operations and life-cycle management. He joined euNetworks in 2011. Michael holds an engineering diploma in telecommunications and is working in the alternative network operator industry for now 20 years. He started his career in IBM and worked in scientific networks when working for the computing center of Berlin Free University. He had various senior technical and management roles when working in network operators like interoute, lambdanet and teragate. Michael had leading roles during past M&A activities of euNetworks making sure a fast frictionless integration maintained the lean operations approach of the company. Michael is directly involved in the design of high scalable solutions in the big content and hyperscale segment.
