   Plenary

   Just a few years ago, free-space optical communication (FSOC) systems were considered by many to be too complex or expensive to offer any practical benefits. Today, there are thousands of FSOC terminals operating in space, enabling revolutionary space and terrestrial communications systems. We will review the history of FSOC development, discuss its present applications, and consider areas where future development will enable new communications capabilities near Earth, and beyond.Authors: Bryan S.

   Scaling Data Centers Is in Conflict With Increasing Interface Speeds

   Presenter: Pradeep Sindhu, Microsoft, United States

    Presentation Details

   Plenary

   This talk argues that the historical trend towards ever faster network port speeds in Ethernet networks is increasingly in conflict with building efficient, massive scale data centers. To support these data centers, the industry needs to fix port speed at a technology “sweet spot” of around 200Gbps and instead scale networks by increasing the number of ports (the radix) on NICs and switches.Authors: Pradeep Sindhu, Microsoft
