Abstract

In many areas, Internet connectivity is primarily via low-end mobile devices capable of only 2G or 3G connections to cellular networks. But many application developers live and work with much faster computing platforms and networking environments. Does the infrastructure need to change to accommodate the continuing use of these devices? Is this a transient condition of uneven development, or do we need to re-architect and re-design systems to better cope with connectivity diversity?

Key transports had assumptions built on wireline networks. The next billion users won't be on wireline networks, and even current users with access to both wireless and wireline networks use wireless networks more often. What does designing for the networks they *will* be on look like - whether at the transport layer or in the application, or at the interface between the two?

In this session during IETF 93, panelists will try to better understand the diversity of Internet connectivity and terminals, and discuss the challenges and responses to these modes of Internet connectivity including:

How application developers are dealing with terminal and connectivity diversity
Considerations for protocol developers
How restricted connectivity impacts user behavior
Design principles that could be extrapolated from the data and the technical responses to date
How power management and connectivity management interact

Ted Hardie, independent

Ted Hardie currently works for Google, putting networks, protocols, and people together.

Ted first worked in the Internet field in 1988 when he joined the operations staff of the SRI NIC. He later became the technical lead for the NASA NIC, part of the NASA Science Internet project. After leaving NASA, he joined Equinix as its initial Director of Engineering before taking on the role of Director of Research and Development. He was an early-stage executive at Nominum before joining Qualcomm R & D. While he was Qualcomm’s Director of Internet and Wireless, he served the Internet community as a member of the Internet Architecture Board and as an Applications Area Director for the IETF. He served as Trustee of the Internet Society from 2007 to 2010, and as its Treasurer in 2008 to 2010, while Managing Director of Panasonic’s Silicon Valley Wireless Research Lab.Dr. Hardie received his bachelor’s degree from Yale and his doctorate from Stanford. He has been a Fulbright Fellow and a Yale-China Fellow, both in Hong Kong.

Ted is currently a member of the IAB, lead for its program on privacy and security, and its Executive Director.

Blake Matheny, Facebook

Blake Matheny is an Engineering Director at Facebook where he is responsible for systems including the Linux Kernel as well as the Load Balancing infrastructure serving over a billion users and many millions of requests per second. Blake has been working on large scale distributed systems for more than ten years, and is currently enamored with C++11, approaches to asynchronous computation, and scheduling algorithms. Although formerly from NYC, Blake currently lives in California with a cat that hates him, his wife, and their collection of books. You can follow Blake at http://fb.me/blake.r.matheny or @bmatheny.

Henning Wiemann, Ericsson

Henning Wiemann joined the Wireless Access Networks branch of Ericsson Research in 2000 after receiving his diploma degree in electrical engineering from the University of Technology in Aachen, Germany. At Ericsson Henning has had a leading role in LTE link layer protocol design with a strong expertise in scheduling and quality of service. Since 2009 Henning is participating in the 3GPP RAN2 working group which is responsible for the radio interface architecture and protocols. In 2010 he led Ericsson’s RAN2 standardization team as technical coordinator and since 2011 he is the elected chairman of 3GPP RAN2. As principal researcher he nowadays also works on concepts for 5G.
