University of British ColumbiaElectrical and Computer Engineering
The Goal: The Pacific Institute for Network
Integrity and Performance Studies: will add wireless infrastructure to BCIT’s
Internet Engineering Lab will provide research and development
facilities for use by both academia and industry
will be a unique Canadian facility for developing and evaluating innovative methods that ensure and enhance the performance of both wired and wireless networks
Research Themes Network Integrity – identify and correct
protocol vulnerabilities and other security issues
Link Characterization – develop models that enhance the accuracy of network analysis and simulation
Network Performance – assess and improve the performance of wireless networks in the presence of severe traffic and channel impairments
Outline Where are we coming from? How does wireless fit in? What are the research themes?
1. Where are we coming from? BCIT’s Internet Engineering Lab is an advanced research facility for applied
R&D in networking technologies. Concentrates on Internet protocol problems and projects, focusing on the
following areas: Quality of Service Network Performance Evaluation Internet-Enabled Process Control Networks Network Security
IEL Floor Plan
Equipment Room 14 full-height open equipment racks for common equipment. 10 full-height closed equipment racks for
corporate members. All connections run
through a central cross-connect panel.
IEL Control Room All equipment controlled through KVM switches to 6 consoles in operations
room: Windows/Linux hardware configuration tools. Telnet connections via in-band Ethernet. Telnet connections via out-of-band Ethernet & serial.
UTP and Fibre ports for workstations.
Voice and video multi-media services.
Logical Structure of the IEL
Remote Operations Researchers can operate lab equipment
remotely via VPN connection. Physical adds/moves performed by lab
staff.
History of IEL 1998 – Concept developed by Michael
Hrybyk. 1999 – Received $900,000 0f CFI and BCKDF
funding to create lab infrastructure. 2000 – Founding members form advisory
panel. – Construction of lab begins. – Spirent Communications becomes primary lab sponsor.
2001 – Lab construction complete (May) – Lab officially opened June 11th
Some Current Activities Founding member of the ATEAM (Advanced
Test Engineering and Measurement), including: Spirent Communications (sponsor) Centaur Lab (North Carolina State
University) Ohio Internet2 Technology Evaluation Center CalNGI Network Performance Reference Lab
(San Diego Supercomputer Center) Universidad Nacional Autonoma de Mexico
Conducting numerous network performance studies for various high profile industrial clients
Some Current Activities - 2 Conducting numerous network performance studies
for various high profile industrial clients International partnerships and collaborations:
Performance of Industrial Ethernet Networks U.S. National Institute for Standards and Technology and General Motors ISA – Instrumentation, Systems and Automation Society
Identification of Protocol Vulnerabilities National Infrastructure Security Coordination Centre
(UK) Cisco Systems – Critical Infrastructure Assurance Group
2. How Does Wireless Fit In? The growth and penetration of wireless
networks into the Canadian economy and society in recent years has been impressive
IDC Canada projects double-digit growth in the Canadian wireless sector: $7.1 billion in 2003; $10.3 billion by 2006
The potential of wireless networks for yielding economic, social, and even environmental benefits are considerable
Trends in Wireless Voice -> dispatch -> email -> network access -
> m2m Growing integration of wired and wireless
networks into homes, offices, industrial plants, critical national infrastructures
Continuing need to boost coverage, throughput, capacity, and reliability
New physical layer technologies: UWB, MIMO, other advanced modulation schemes
Wireless access vs. wireless networks: Routing, QoS, throughput, etc.
Growing role of IETF and IEEE 802 in setting wireless standards

PINIPS = BCIT IEL++BCIT’s Internet Engineering Lab:
focuses on integrity and performance of wired networks
The Pacific Institute for Network Integrity and Performance Studies: will extend focus to include wireless
networks and wired networks with wireless networks
will emphasize a multidisciplinary and multi-institutional approach to research
Unique aspects of PINIPSEmphasis on network integrity and
performance rather than new modulation and coding schemes or new content
Emphasis on proof-of-performance rather than proof-of-concept
A common framework for dealing with wired and wireless networks
PINIPS Research Disciplines Industrial applications of data networks Protocol vulnerability analysis Traffic modelling Networking and security protocols Propagation and channel modelling Antenna array communications systems Multi-user detection Software development for mobile and personal
communications Emergency and disaster communications
