Focal Areas for winter 2009 Joint Techs

Campus Challenge
End to End Campus Cooperation
The Impending Crisis in Routing and Networking
Convergence Technologies

 Campus Challenge

The campus networking environment faces numerous challenges – it needs to support an increasing number
of advanced services, support the demand for more bandwidth, keep up with the increasingly sophisticated
cyber security challenges, and make infrastructure investments to support future technologies. All this while
operating with (hopefully) flat budgets!

Suggested topics include (but are not limited to):

·        Advanced services to address

-         End-end performance challenges

-         QoS for voice, video, and dynamic circuit services

·        Demand for more bandwidth on the campus

-         Increasing deployment of 10 GigE throughout the campus

-         Evaluation of 40 Gig and 100 Gig aggregation links

·        Security infrastructure build out & management

-         Integrating solutions to provide defense in depth

-         Managing the diverse threat vectors (e-mail, web, identity theft, etc)

·        Building out the infrastructure

-         Wiring closet upgrades to support VoIP

-         In-building cellular coverage

-         Wireless infrastructure (more coverage, newer technology)

End-to-End Campus Cooperation

The "End-to-End Campus Cooperation" focus area at Joint Techs will bring together leaders from the campus,
gigapop, and national backbone communities to discuss different aspects of end-to-end networking challenges.
Some of the topics included in this focal area are:

·        Circuit Services

-         Static Circuits

-         Dynamic Circuits

-         Routing Implications of Circuits

·        Issues with using multiple backbone providers

-         Traffic engineering across multiple domains

·        Performance Measurement

-         Monitoring

-         Debugging multi-domain services

  The Impending Crisis in Routing and Networking

The "Impending Crises in the Internet" focus area is a response to growing concerns that the Internet community 
is facing the greatest technical challenges in its history.

 The shortage of IPv4 address space is the main cause of this concern. The Internet community must respond 
to a situation where the number of devices using the Internet continues to grow at an accelerating pace, yet 
the fundamental resource of the Internet – number space – is obviously finite.

 At the same time, multiple connectivity for end sites and the issuance of smaller blocks of address space strain
 the ability of core routers to compute and store routing and forwarding tables. There are many concerns
 that this engenders:

·        How is address exhaustion affecting the usability of the Internet and restricting its growth? Will it lead to
 markets in number resources? How will it affect the growth of the routing table? What would be the 
impact of a substantially larger routing table?

·        What is the impact to the Internet of increased usage of NAT and other stop-gap tools to extend 
the life of IPv4? Can applications cope with the resulting breakage of the end-to-end model? 
Are there new routing technologies on the horizon that might address some of the potential problems?

·        How might IPv6 fit into this problem? Is it a solution, a new problem, or a solution looking for a problem? 
Can we create a usable dual stack environment in the Internet? If IPv6 is part of the solution, how can 
we ensure that IPv4 and IPv6 networks can communicate?

 These are very real problems that the US Research and Education community must address if it is to 
continue to play a leadership role in the Internet community.

Convergence Technologies

After many years of hype over the coming of convergence technologies, the real merging of traditional
voice, data, and video teleconferencing technologies has arrived. Within just a few years of its introduction,
hand-held multipurpose devices such as the Blackberry have become ubiquitous, Voice over IP telephony
is becoming increasingly prevalent, and video teleconferencing technologies have migrated from stand alone
facilities to the desktop. Traditional “IM” technologies have also evolved to provide ad-hoc audio and video
conferencing capabilities at no cost, with the use of applications such as Skype becoming increasingly prevalent.
