SpeakerAmin M. VahdatScience Applications International Corporation Chair Professor Department of Computer Science and Engineering University of California San Diego TitleScale and Programmability in Google's Software Defined Data Center WAN |
|
AbstractWe present the design, implementation, and evaluation of B4, a private WAN connecting Google's data centers across the planet. B4 has a number of unique characteristics:i) massive bandwidth requirements deployed to a modest number of sites, ii) elastic traffic demand that seeks to maximize average bandwidth, and iii) full control over the edge servers and network, which enables rate limiting and demand measurement at the edge. These characteristics led to a Sofware De ned Networking architecture using OpenFlow to control relatively simple switches built from merchant silicon. B4's centralized traffic engineering service drives links to near 100% utilization, while splitting application flows among multiple paths to balance capacity against application priority/demands. We describe experience with three years of B4 production deployment as well as implications of both SDN and WAN deployments on merchant switch silicon. BioAmin Vahdat is a Distinguished Engineer at Google where he is the Technical Lead for networking and working on projects in Software Defined Networking and network virtualization. Vahdat's work focuses broadly on computer systems, including distributed systems, networks, and operating systems. He has worked on a range of projects including energy efficiency in data centers, high performance system virtualization, data consistency models for wide-area replication, and data center network architecture. He received a PhD in Computer Science from UC Berkeley and has served on the faculty at Duke University and UC San Diego. Vahdat is an ACM Fellow and a past recipient of the NSF CAREER award and the Alfred P. Sloan Fellowship. |

Keynote 2
SpeakerTom AndersonRobert E. Dinning Professor Department of Computer Science and Engineering University of Washington TitleNetworking as a Service |
|
AbstractQuality of service, resilience against denial of service attacks, route control, very high end-to-end reliability: these are just a few of a long list of features that customers want from the Internet, but can't have, except at enormous expense. We argue that recent advances in high performance network hardware will soon enable a new model where these services will become standard. With a small amount of processing at the ISP edge, ISPs will be able to offer advanced services to both local and remote customers, much as data center cycles and storage are sold to remote users today. The benefit will be to unlock the knot limiting the availability of advanced end-to-end network services. Each ISP will only need to promise what it can reliably provide over its own network resources; end-to-end properties will be achieved by the end customer by stitching together services from a sequence of networks along the path.BioThomas Anderson is the Robert E. Dinning Professor of Computer Science and Engineering at the University of Washington. His research interests span all aspects of building practical, robust, and efficient computer systems, including distributed systems, operating systems, computer networks, multiprocessors, and security. He is the winner of the IEEE Koji Kobayashi Computer and Communications Award, the ACM SIGOPS Mark Weiser Award, and the IEEE Communications Society William R. Bennett Prize. He is an ACM Fellow, past program chair of SIGCOMM and SOSP, and he has co-authored eighteen award papers. |

Keynote 3
SpeakerDavid YenSVP/GM Data Center Group Cisco TitleThe Network is the Cloud |
|
AbstractThe network in the data center has been evolving rapidly in the last few years and will continue to evolve, transforming from being simply passive interconnects to being strategic control panel for the cloud computing data center. The speaker will review different phases of such evolution and the rational for evolving. He will also talk about Cisco's recent leadership switching product introductions, including its fabric automation and hybrid cloud technologies.BioDavid Yen is Senior Vice President and General Manager of the Data Center Technology Group at Cisco. The group covers data center switching, servers, and storage. He is responsible for the Cisco Unified Computing System and the Cisco Nexus switching portfolio, and for advancing Cisco's leadership in the data center to the next level. Yen has nearly 30 years of experience in the technology industry. Before joining Cisco, he was the Executive Vice President and General Manager of the Fabric and Switching Business Group at Juniper Networks, where he led the QFabric multiyear initiative in data center network research and development. Previously, he spent over 20 years at Sun Microsystems. In the 1990s, he led the development of first- and second-generation multi-CPU SMP servers, which transformed Sun from a workstation company to a leading enterprise server company. Later, as head of Sun's Microelectronics Group, he revived the declining SPARC product line, introducing the industry's first 8-core, 32-thread general-purpose processor and making it into a multibillion dollar business. He also managed Sun's storage business for a year. Before joining Sun, he co-founded Cydrome, a mini-supercomputer startup, and worked at IBM Research in manufacturing automation and at TRW in processor development.Yen holds a BSEE from the National Taiwan University and a master's degree and doctorate in electrical and computer engineering from the University of Illinois at Urbana-Champaign. He holds three U.S. patents. |

Keynote 4
SpeakerGeorge PapenDepartment of Electrical and Computer Engineering University of California, San Diego TitleHybrid Datacenter Networks |
|
AbstractHybrid datacenter networks can selectively route packets over either an electrical packet-switched network or an optical circuit-switched network. This kind of network is attractive for scale-out datacenters because of its energy and scaling properties. However, the control plane for this network must precisely synchronize the two underlying networks. We discuss the development of a complete hybrid network with a prototype control plane that provides the necessary synchronization.BioGeorge Papen joins the UCSD faculty in September 2002 from a full professorship at the University of Illinois at Urbana-Champaign. He arrived at UIUC in 1989 after earning his Ph.D. in Electrical and Computer Engineering from the University of Wisconsin. He has been actively involved in professional associations, and chaired recent conferences including the OSA Optical Remote Sensing Conference and High Speed Interconnects within Digital Systems conference, both in 2001. He is a co-holder of three patents. |

Keynote 5
SpeakerTom EdsallCTO Insieme Networks TitleChanging Data Center |
|
AbstractTom Edsall will discuss some of the current trends in the data center from changing topologies to performance to automation to application focus. He will then discuss the requirements for a balanced, pragmatic approach to scale.BioTom is the Chief Technology Officer and a co-founder of Insieme Networks, a subsidiary of Cisco Systems, where he is responsible for system architecture and product evangelism.Before Insieme Networks, Tom has held various roles including Cisco Fellow in the SAVBU group, Senior Vice President and CTO of the Datacenter, Switching and Services Group at Cisco, General manager of the Cisco Data Center Business unit responsible for the MDS and Nexus 7000 product lines, and CTO and co-founder of Andiamo Systems. Prior to Andiamo, he was Vice President of Engineering at Cisco and one of the system architects responsible for the Cisco Catalyst 5000 and 6000 product lines. Two of Tom's products, the Catalyst 6000 and Nexus 7000, have been the recipients of the prestigious Cisco Pioneer Award. Prior to Cisco, he was a co-founder and a member of the senior engineering management team at Crescendo Communications, Cisco's first acquisition. Edsall holds a bachelor's and master's degrees in electrical engineering from Stanford University where he now lectures occasionally. |
