Evite

Today’s networks, both wired and wireless, are evolving at an unprecedented pace. This has opened up a number of opportunities for providing innovative services and content. At the same time, due to the complexity of these networks, a number of challenges including management, security and scalability need to be addressed.


This workshop is dedicated towards novel solutions addressing these challenges. Join us on October 25 and hear from top networking thought leaders and senior research scientists, and get a rare glimpse of the leading edge of this exciting technology landscape.


Preparing for the future of networking now will put you, as networking professionals, in a better position in the years ahead. It is open to practitioners as well as researchers in the field of wireless communications and networking.

9:40 AMWireless into the Future Avoiding Multipath to Revive Inbuilding WiFi Localization
Kyu-Han Kim, Senior researcher and mobility research manager at HP Labs


Despite of several years of innovative research, indoor localization is still not mainstream. Existing techniques either employ cumbersome fingerprinting, or rely upon the deployment of additional infrastructure. Towards a solution that is easier to adopt, we propose CUPID, which is free from these restrictions, yet is comparable in accuracy. While existing WiFi based solutions are highly susceptible to indoor multipath, CUPID utilizes physical layer (PHY) information to extract the signal strength and the angle of only the direct path, successfully avoiding the effect of multipath reflections. Our main observation is that natural human mobility, when combined with PHY layer information, can help in accurately estimating the angle and distance of a mobile device from an wireless access point (AP). Real-world indoor experiments using off-the-shelf wireless chipsets confirm the feasibility of CUPID. In addition, while previous approaches rely on multiple APs, CUPID is able to localize a device when only a single AP is present. When a few more APs are available, CUPID can improve the median localization error to 2.7m, which is comparable to schemes that rely on expensive fingerprinting or additional infrastructure.

10:45 AMNew Paradigms for Multimedia and Security in Wireless Networks New Paradigms for Multimedia and Security of Wireless Networks
Ashish Khisti - Assistant Professor and Canada Research Chair (Tier II), University of Toronto


Multimedia traffic in wireless networks has increased by several orders of magnitude in the last few years, and will continue to do so in the future. To tackle this explosive demand we argue that fundamental changes need to be made in all layers of the protocol stack. This talk will present our recent work on two areas: (1) Error Correction for Low‐Latency Streaming Applications, (2) Efficient Caching mechanisms for Adaptive Streaming. We will demonstrate that through suitable optimizations, significant gains can be achieved over traditional approaches in these systems.

In the second part of the talk, we will present our vision for engineering a secure wireless network based upon principles of physical layer security. In such a system, distributed wireless access points will be designed to cooperatively transmit information signals to the legitimate users in a way that adversarial nodes cannot decode information by eavesdropping. We will highlight several advantages over traditional cryptographic techniques in wireless networks.

11:30 AMEnabling Wireless Apps in the Age of 802.11ac and Cloud Mobility in Networking, glimpses of the near future
Stéphane Laroche, Distinguished Technologist, Hewlett-Packard


We will review the current mobility landscape in networking and the impact of recent trends on the architecture of the network. We will briefly look at advances in wireless technologies such as 802.11ac and how the rise in wireless usage, driven by both an increase in the number of mobile devices and in bandwidth hungry applications like video, will change networking in the future. Finally, we will discuss how developing application frameworks such as SDN will improve network performance and overall experience for network users and administrators alike.

1:15 PMNew Directions in Networking Research On the SAVI Testbed for Software-Defined Infrastructure
Alberto Leon-Garcia, Distinguished Professor, University of Toronto


First we present a very brief overview of networking research at the University of Toronto. Next we introduce the NSERC Strategic Network for Smart Applications on Virtual Infrastructure, which is a national research network based at U of T. We discuss SAVI’s investigation on the role of virtualization and software-¬‐defined infrastructure in future application platforms. A multi-¬‐tier computing cloud is presented in which resources in the “Smart Edge” of the network play a crucial role in the delivery of low-¬‐latency and data-¬‐intensive applications. Resources in the Smart Edge are virtualized and managed using cloud computing principles, but these resources are more diverse than in conventional data centers, including programmable hardware, GPUs, and even wireless access networks. We present SAVI’s research program, and we describe the design of the SAVI Testbed and its deployment in a Canadian national testbed. The design features a novel Software-¬‐Defined Infrastructure manager that operates on top of OpenStack and OpenFlow.

Alberto Leon-Garcia
Professor, Canada Research Chair, Autonomic Service Architecture
University of Toronto


Dr. Alberto Leon-Garcia is Professor in Electrical and Computer Engineering at the University of Toronto. He is a Fellow of the Institute of Electronics an Electrical Engineering "For contributions to multiplexing and switching of integrated services traffic". He is also a Fellow of the Engineering Institute of Canada. He has received the 2006 Thomas Eadie Medal from the Royal Society of Canada and the 2010 IEEE Canada A. G. L. McNaughton Gold Medal for his contributions to the area of communications. He holds a Canada Research Chair in Autonomic Service Architecture.


From 1999 to 2002, Prof. Leon-Garcia was founder and CTO of AcceLight Networks in Ottawa which developed an all-optical fabric multi-terabit, multiservice core switch. He holds several patents and has published research extensively in the areas of switch architecture and traffic management. His current research interests are focused on application-oriented networking and autonomic resources management with a focus on enabling pervasive smart infrastructure. His research team is currently developing a network and applications test bed that will enable at-scale experimentation in new network protocols and distributed applications.


Professor Leon-Garcia is recognized as an innovator in networking education. In 1986, he led the development of the University of Toronto - Northern Telecom Network Engineering Program. He has also led in 1997 the development of the Master of Engineering in Telecommunications program, and the communications and networking options in the undergraduate computer engineering program. He is author of the leading textbook Probability and Random Processes for Electrical Engineering, and co-author of the textbook Communication Networks: Fundamental Concepts and Key Architecture.
