“Internet Who?”

Elevator Explanation

• _{Internet2's mission is to develop and deploy advanced network}

applications and technologies, accelerating the creation of tomorrow’s Internet

Who we really are

• Membership organization of 200+ US research universities • _{Parent 501.3c (UCAID) has board of university presidents} • Project supported by numerous partnerships (government,

industry, international)

Goals

• _{Enable new generation of applications}

• Re-create leading edge R&E network capability • Transfer capability to global production internet

Internet2 Focus Areas

Advanced Network Infrastructure

• 10 GB Abilene backbone • Advanced regional networks • 100

MB to the desktop • National fiber-optic facility

Middleware

• Directories • Authentication • Authorization • Call routing

Engineering

• _{Multicast • IPv6 • Measurement • New Arch}

Advanced Applications

• Gigabit+ file transfer • Tele-immersion • Remote instrumentation

• Distributed computation • Virtual laboratories • Distance learning • Digital video • VoIP • Integrated Communications

The University Enterprise

Universities are strange beasts

• Part carrier / part enterprise

Convergence is finally happening

• Network convergence

• Organizational convergence

Replace or displace?

• Economics are driving POTS-replacement

• Younger users, however, are defecting from POTS

(cellular, AIM-YIM-...)

• Hence, a serious look at developing and deploying

P2P and the Enterprise

P2P file-sharing explosion

• Internet2's network connectivity +

Napster's middleware = P2P FS Explosion

Similar potential for real-time apps

• This time get ahead of the curve and provide the

enabling middleware ourselves

"Paths in the snow"

• Don't predict how users will want to communicate • Users are highly-motivated to communicate

• Connect them and watch what happens

Network Connectivity (high-performance, end-to-end IP transit)

Network connectivity:

Can connections be established between communicating IP addresses with high-performance and high-availability?

Application Connectivity (SIP/SIMPLE call and presence routing)

Application connectivity:

Are there protocols and call routing infrastructure to establish connections between communicating applications?

Connective Middleware

Demographics

 ~3.8 million students (tech-savvy, talk a lot, adapt easily)  And, by the way, they graduate (tech-transfer à la email)

Institutional Commitments

 Internet2 members have committed to advance IP

communications and promote collaborative apps

 Many are looking for ways to reverse eroding voice revenues

Connectivity

 Great networking connectivity

 High-bandwidth, low-loss, low-jitter

 End-to-end transparency (few NATs)

 IPv6 and multicast too!

 Emerging middleware infrastructure for AuthN/Z

 Need to build on this to connect users with each other!

SIP.edu Charter

Goals

• Grow number of SIP connectivity and use

• Increase value proposition for end-user SIP adoption • Promote converged electronic identity

• Low entry-cost means for campuses to...

–Provide a useful initial service

–Start getting their feet wet with SIP

Means

• SIP.edu Cookbook (http://mit.edu/sip/sip.edu/) • Partnering with vendors (Cisco)

Addressing

 Users should not be burdened with device

addresses, when it’s people they really care about

 Addresses should be mnemonic and empower

enterprises to manage the identities of their users

 sip:[email protected]

 It’s time to put E.164 phone

numbers behind us!

 A.G. Bell did not say...

“+1-617-637-8562, come here. I need you!”

Voice DR Charter

PSTN and Internet each have strengths

and weaknesses

Combine VoIP and PSTN for better voice

survivability than either architecture alone

Partner with carriers and vendors to provide

a disaster recovery service to Internet2

members

Different Networks, Different

Strengths / Vulnerabilities

•Open to internal attack

•Mileage may vary (no QoS) •CO is single point of failure

•Local loop single point of failure •Call-blocking during heavy volume

St

•Network routes around failure •Packet-level call multiplexing •Adaptive, loss tolerant codecs

•Gradual degradation, not blocking •Reliable QoS (once connected)
