End to end Performance
View whole path as systemGive end users (and their system/network admins) tools to discover, diagnose, fix (or learn who to contact to fix) problems
Network measurement and monitoring framework (piPEs)
• Use data from regularly-scheduled tests; archived data from others’ tests
• Provides capability to support HOPI efforts

Middleware
Middleware is the stuff that makes “transparent use” happen, providing persistency, consistency, security, privacy, and capability
http://middleware.internet2.edu

Federated Authentication
Scalable, decentralized infrastructureCritical to a broad range of initiativesBeing adopted and implemented
• Industry• International
Middleware is an increasingly enabling element
Shibboleth
![Page 20: CANS2004 Conference 30 November 2004 Douglas Van Houweling, President & CEO Internet2](https://reader036.vdocuments.net/reader036/viewer/2022062809/568159f9550346895dc744e0/html5/thumbnails/20.jpg)

Security
Require network security approaches that:• Minimally compromise network performance and allow
applications requiring advanced network services to function• Sustain, in so far as possible, the end-to-end nature of the
Internet architecture
Network security, host software, and middleware become inter-dependent
Security at Line Speed• NSF-funded workshop• SALSA steering group
Outcome – An authenticated Internet based on trust communities?

Imperatives for the Advanced Networking Community
Real progress in Internet technology and use is in doubt
• Not just connectivity, but performance, security, and reliability• New applications require capabilities unlikely to be available
through evolutionary change
The higher education and research community must provide leadership
• Industry efforts focused on profit, maintaining the status quo• Our organizations continue to treat the Internet as a Commons
No organization, national or regional can succeed in isolation – we must engage these problems collaboratively on a global scale

Agenda for US - China Cooperation
Collaborate on the development and deployment of new network architectures
• Within China: access to multiple wavelengths• Experimentation with new equipment/technologies• Exploring new service architectures and business models
Connectivity between our countries• Work on new architectures important• Even before multiple wavelengths are available

Middleware/Security/Performance• Multiple dimensions and intersections between these areas
• US can benefit from China expertise and urgent demand for IPv6
–End-to-end principle and NAT-less networks–Performance implications–Security implications
• Instrument our respective networks and interconnections–Performance-based measurements: partial-path analysis to
diagnose problems (see tonight’s performance demo)–Data for network researchers (Abilene Observatory model)

Agenda for US – China cooperation
Working together to support international science projects

topology/infrastructure, enhance performance • Several VLBI sites in China• Work together to support via our respective networks (and
with trans-Pacific link managers)High-energy and nuclear Physics
• Several panelists later in the week• Many sites, scientists• Massive bandwidth needs

Conclusions
US and China have well-developed domestic advanced networking initiatives and infrastructures
We have much to learn from each otherWe have much to gain from working together to support broader collaboration between our communities
