Panel IV: What Is Next for Data Center Interconnects?

Wednesday, 11 March
15:30 - 17:00
Expo Theater I

Moderator: Loukas Paraschis, Senior Director, Infinera, USA

Panel Description:

The networks interconnecting datacenters, often referred to as Data Center Interconnects (DCIs), have grown more than any other transport infrastructure in the last decade, and DCI’s are projected to grow by several orders of magnitude in the coming years.  The economics associated with DCI growth have motivated: 1) dedicated DCIs accounting for some of the most spectrally efficient fiber networks deployed globally, and 2) a new class of purpose-built systems optimized for throughput and power consumption.  The emergence of DCIs has led to extensive 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 will discuss the extent to which these innovations have been adopted in current and future DCI networks.  For example, 400GE coherent WDM pluggables in DCI routers have been advocated, often combined with system and control-plane disaggregation, in open (multi-vendor) network architectures that minimize operational overhead without compromising significantly transport network performance. At the same time, the potential value from optimization and traffic engineering, such as from network analytics, potentially even combined with optical margin “harvesting” or restoration in addition to IP/MPLS protection, has also recently been proposed.   

This panel will introduce the views of several industry leaders in this area and evoke discussion among panelists and the floor.
