Keynote 1: Eliminating Network Delay and Packet Loss Without a Clean Slate
Wednesday, February 22nd, 11:00-11:30am
Larry Roberts
CEO
Roberts Consulting
Recognized as one of the four founders of the Internet, Larry Roberts received the National Academy of Engineering Draper Award and the Principe de Asturias Award "for the development of the Internet" along with Leonard Kleinrock, Robert Kahn, and Vinton Cerf. Currently an independent consultant, he has founded 4 companies; NetExpress, ATM Systems, Caspian Networks, and Anagran, continuing his goal of improving network technology.
Larry Roberts was the Chief Scientist of the Advanced Research Projects Agency (ARPA) where he designed and built ARPANET, the first packet network and the predecessor of the Internet. While at ARPA, he wrote the first email program and invented the access technique now used for WiFi and wireless. He later founded and ran the first commercial packet network, Telenet (now Sprint), and invented the X.25 protocol which dominated world networking from 1975 to 1990. His other awards include the L.M. Ericsson prize for research in data communications, the ACM SIGCOMM award, the IEEE Internet award, and the NEC Computer and Communication Award. A member of the National Academy of Engineering, he holds BS, MS, and PhD degrees from MIT.
Abstract: Eliminating Network Delay and Packet Loss Without a Clean Slate
Designers and operators often believe that eliminating delay and packet loss in networks would require a complete rebuild or “clean slate”. Since this is virtually impossible to do, the International Telecommunications Union (ITU) has taken a new approach. ITU has recently approved the Q.3313 protocol, which optimizes response time and throughput and eliminates lost packets. Usually, when TCP, UDP, and IPSec traffic traverses Ethernet networks, switches and routers introduce delay and packet loss even under modest loads. TCP, in particular, operates with slow start, causing major delays for interactive traffic while the flows try to increase their speed. The new ITU protocol provides optimal performance for TCP, eliminating slow start and allowing each flow to jump to the maximum rate feasible, considering other traffic, after one round trip. For web access, this would provide sub second page times, a 10:1 improvement. The protocol also eliminates network delay and delay jitter, leaving only speed of light delays. This means the round trip time would be improved typically 3:1. Peak TCP data transfer rates are currently limited by retransmission buffer size to under 100 Mbps, but Q.3313 would immediately permit transfer rates up to 1 Gbps or more, depending on the minimum trunk speed. If deployed in an office complex, Q.3313 could greatly reduce file transfer times and provide fractional second interactive access, thus greatly increasing productivity. In an ISP point of presence, it would improve customer satisfaction dramatically. The presentation will explain the reasons for current network congestion problems and how the new protocol fixes them.

Keynote 4: Ethernet-Based Data Centers in the Cloud Computing Era
Wednesday, February 22nd, 2:30-3:00pm
Greg Sherer
Vice-President - Server and Storage Strategy
Broadcom Corporation
His previous positions include being CTO for Emulex and Neterion. He is a technology industry veteran with almost thirty years of experience in engineering and business development. His diverse career includes contributions as both a technical team member and a proven leader in bringing emerging products and technologies to market. Greg holds several patents and remains active in new product development.
Abstract: Ethernet-Based Data Centers in the Cloud Computing Era
For years, the corporate data center has been growing and evolving by increasing the scale and speed of three separate entities to keep up with IT demand, namely:
- Server farms
- Storage networks
- Data networks
Much like the process by which diamonds are created, data centers are being reshaped dramatically through current economics and the need for business agility. This session will explore the following pressures on data center networks:
- The new edge - server and I/O virtualization
- One wire - network and storage convergence
- Fast, flat, and fat fabrics - network virtualization
These architectural advances, which have been heavily influenced by the advent of cloud computing, will forever change the shape of the data center. The common thread that unites and provisions the new data center is Ethernet. We will discuss how faster speeds and flatter and converged networks that are virtualized at every level (server, I/O, and network) form the foundation of the new data center fabric.

Ken has 3 simultaneous engineering degrees from MIT and holds a Ph.D. in Computer Science from Stanford.
Abstract: Rethinking the Data Center
Network virtualization is a key development in Ethernet network architecture. By decoupling logical topology (as seen by the application or virtual machine) from physical topology (the physical connections between servers and switches), it has a profound impact on network design and usage. Administrators can use it to allow for multipathing, move virtual machines across subnets, stretch virtual LANs between data centers, or provide thousands of secure subnetworks, allwithout proprietary fabrics or forklift upgrades. This presentation will cover how network virtualization works, what problems it solves, and how equipment vendors and standards bodies are approaching it.
