Network Scalability vs. Evolving Communication Patterns (Invited Talk)
Mike Wittie (University of California, Santa Barbara, USA)
[Slides]

Enabled by capable mobile devices, new web services, and expanding wireless coverage, personal digital communications are undergoing a revolution. Mobile devices that combine multi-mega-pixel cameras with high definition displays and take advantage of wide-spread network connectivity allow users not only to consume, but also to create vast amounts of content. Online social networks, and many applications that include a social network component, allow users to broadcast new content far beyond their social circle. Finally, the popularity of different real-time communication applications, such as video chat and multiplayer games, increases as they enter the mobile arena. These changes result in more inter-user traffic, as opposed to traditional client/sever downloads, and traffic that is increasingly dependent on low delay, rather than just high throughput.

I will discuss the evolution of user communication patterns and explain why existing strategies for scaling of network and hosted application resources are ill suited to support the growing demand and changing communication patterns. I will also present work that addresses these scalability challenges in cellular networks and online social networks. The overall goal of this talk is to show that "throwing capacity at the problem" leaves unsolved many problems of growing demand and that we need to work towards alternative scaling strategies.

7:30 PM: Informal Dinner

We will organize an informal dinner. You are cordially invited to join us. The dinner place is Lombardi's, which is part of the Bayside area. It is in walking distance from the conference/workshop venue and takes approximately 15 minutes. We will meet at the lobby of the conference hotel around 7:00 pm, or join us directly at Lombardi's around 7:30 pm. Directions from the venue.
