Title: Optical Technologies for Hyper-Scale Cloud Datacenters
Hyper-scale cloud datacenters, where most of the Internet services such as e-commerce, video streaming and social networking are running, have become the fundamental infrastructure for cloud computing and big data services. The fast-growing demand for computing and storage power, which is provided by massive numbers of powerful servers connected together in data centers, requires scalable and efficient datacenter networks. Most of the interconnects in today’s hyper-scale datacenter networks, including both short-reach and long-reach interconnects, use optical technologies. The demand for large volume, fast traffic growth and short technology life cycle optical interconnect technologies present a big challenge for optical communication industry. In this talk, we will present requirements and challenges of optical technologies for hyper-scale datacenters, including both short-reach optical interconnects and long-reach optical transport technologies. Potential solutions to solve these challenges are discussed.

He has also led groups working on photonic integration in III-V and silicon materials. Prior to joining Bell Labs, was a Visiting Scientist at NEC Research, Princeton NJ, researching optical interconnects for high performance computing systems. He has authored over 200 publications and patents on both devices and systems in the field of optical interconnects and switching. He has chaired and been on several IEEE-LEOS, OSA, and SPIE conference programs committees, in the field of optical interconnects and switching. He is a Fellow of IEEE.
Title: Future switching requirements for long haul and metro networks
Optical networks serve as the cornerstone of our connected society, enabling the information superhighway that delivers the Internet all across the globe. As the number of users and data services increase, the network technology and architecture must adapt for it to continue to efficiently and economically support the larger traffic loads. Optical communication systems, have demonstrated equivalent per fiber capacity scaling over the last decades to match traffic load and today’s commercial long-haul systems can carry 50Tb/s on a single fiber. However, we have now reached the limit of the capacity on a single fiber and it is anticipated that to continue to achieve the anticipated 40% pa growth rate in capacity it will require the use of many more parallel fibers. Driven by this change in fiber infrastructure and the larger transported capacity, the network switching elements and their functionality must also evolve.

Title: Network Hardware and Software Co-Design for Data Centers
Cloud computing, which is very successful both technically and commercially, has been evolving from enterprise data centers to warehouse-scale data centers. Distributed computing applications are the major driver of the cloud evolution. Distributed systems have existed in a loosely-coupled, CPU-centric style for several decades, but their performance improvements are now declining, due to the slowing of Moore’s law, explosive data growth, and unprecedented computational demands. Increasingly, near-storage compute and in-network compute are becoming the way forward, leveraging specialized network hardware and software to provide reliable, predictable, efficient and high-performance infrastructure. The talk will cover recent Xilinx research and development on data center hardware and software co-design from a networking perspective. And it will also discuss further directions that should be investigated next.
