Internet2 Origins and Mission
• Started in 1996 by initially 34 US universities
– 100 universities by January 1997
– Internet2 incorporated as nonprofit organization Sept 1997
• Mission
– Develop and deploy advanced network applications and
technologies, accelerating the creation of tomorrow’s
Internet.
• Goals
– Provide a national, advanced network environment in
support of members’ research, teaching, learning and clinical
missions
– Upon which a next generation of leading-edge network
applications and technologies can be developed
– Transfer experiences and technologies to the broader
educational community and public in general
Internet2 - today
• US-based membership organization
– 207 US University members
– 66 Corporate members
– 47 Affiliate members
• Including several US government research labs
– 2 Association members
– 46 International partnerships
Internet2 Network
Infrastructure Overview
• Campus
• Regional Aggregation
– Example: by US state, metropolitan
region, multi-state region
• National
– Backbone network infrastructure
Abilene Backbone Network
Connecting to Abilene
History of IPv6 in Internet2
• Tunnel network deployed 2001
– First IPv6 tutorial at Lincoln joint-techs meeting
– Over ten more since then
– Now focus more on server and applications support
• Migration to native, dual stack implementation at end of 2001
– Before upgrade began
– Using 2.5 gigabit routers interfaces
– Began migration of connectors
• Native dual stack was default for the upgrade to 10 gigabit
router connections
• Early testing
– 8 gig tests from Sunnyvale to Washington DC
– IPv4, IPv6, and mixed IPv4/IPv6
– No distinguishable difference in performance
Still Working Well
• Our dual-stack IPv6 network continues
to perform well
• Active testing shows no difference
between IPv4 and IPv6 performance
– Routinely perform 1 gig performance tests
• Changes: improving connectivity to
others

Deployment Issues
• While Abilene and Gigapops are IPv6enabled, a “last mile” problem persists
as it relates to IPv6. Theories:
– Some legacy network hardware does not
support IPv6
– Difficulty convincing administrators of value
– Ensuring security isn’t being compromised
• Tools and experience lacking
– Many applications don’t support IPv6
Source: Joe Breen, University of Utah
Deployment Issues
• Many monitoring tools are missing,
impacting security
– Schools are reluctant to deploy fully
because of potential for attacks
• For example, difficulty in supporting access
lists that monitor address/port number –
extended header implementation problem
Support for IPv6 Deployment on
Campus, in access networks
• Tutorials
– Two day workshops, hands-on experience
– Descriptions and planning guides
• http://ipv6.internet2.edu/workshops/index.shtml
• http://ipv6.internet2.edu/workshops/setup/
– Alternate discussion/lecture with hands-on lab
exercises
– Slides are available
• http://ipv6.internet2.edu/presentations/
Internet2 IPv6 Goals
•
•
Support and encourage development of advanced applications using
IPv6
Create a national infrastructure to support IPv6 for the Research and
Education Community
– Implement IPv6 on Abilene Backbone
– Encourage deployment of IPv6 throughout the Internet2 infrastructure
– Support end-2-end transparency for IPv6 advanced applications
• Important issue for high performance applications
• High performance applications often have trouble with NATs
• Provide a more robust infrastructure to provide security
•
•
Educating the Internet2 IPv6 user base
Support interconnectivity and transit during the initial stages of IPv6
deployment
– Actively looking for peers – commodity and research and education peers
Internet2 Commitment
• Internet2 is committed to deploying an IPv6
native dual stack network for the research
community.
• Internet2 is committed to encouraging
connectors, peers, and members to fully
deploy IPv6 on their networks.
• Internet2 will monitor IPv6 penetration in the
future to provide guidance to the community.
– Network penetration.
– Availability of software and tools
– Security Issues
Abilene changes relevant to
international peers
• IPv6 and multicast transit traffic
– Background: Abilene peers with commercial IPv6 and
multicast networks
• This is an exception to our policy not to peer with commercial
networks
• As a way to encourage commercial deployment of IPv6 and
multicast
– Change: no longer routinely announcing non-customer
routes to commercial IPv6 and multicast peers – on request
– Rationale: some commercial peers complaining because it is
not standard commercial practice to announce noncustomers
– Impact: some international peers may have lost previously
seen routes to commercial v6 and multicast networks via
Abilene
NewNet
• A hybrid network providing IP and point-to-point
services that can be rapidly provisioned and supports
both production and experimental capabilities
• Uses innovative optical technology
– Simple and convenient add/drop technology
– Simple and convenient wave setup
– Demonstrated high reliability in initial period of operation on
the carrier’s system
– Low cost provides attractive fee structure
• Architecture has maximum flexibility. Every RON can
access every wave on the system if needed
• System includes grooming capabilities - lightpaths
can be built over Ethernet or SONET
NewNet Plans & Goals
• Dedicated, innovative optical system deployed nationally –
13,000 miles in extent
• Every RON connects to a hybrid network providing IP and
dynamic point-to-point services
• Every RON connects to a ring in a metro location not requiring
extensive backhaul
• Internet2 retains complete control of the layer 1 optical system
including provisioning and switching of wavelengths
• Internet2 focus on networking
– Carrier is responsible for SLA, sparing and reliability
• The system is capable of supporting a variety of network
research projects
• Minimal Conditions of Use
Lightpath Capabilities
NewNet Properties
• Expect 20 - 24 connectors
– Simple and consistent connection scheme
– Promotes aggregation
• IP network built on top of optical system
– High reliability - architecture provides a variety of protection
options
– Commodity service offering - standard connection will include
commodity services
– Will likely use fewer routers, emphasizing point-to-point
capabilities and hybrid networking
– Potential near term option of 40 Gbps
NewNet Properties, continued
• Initially provisioned with ten 10-Gbps wavelengths
(100 Gbps)
• Capacity: up to 80 wavelengths (0.8 Tbps)
• Scalability: Potential for 40 & 100 Gbps wavelength
support
• Reliability: Carrier provides standard service
assurances for these wavelengths
– Provide a variety of different types of reliability
• Flexibility: Support for dynamic provisioning and
wavelength switching
• Term: 7 years
Example Circuit Services
• Short Term Dynamically Configured Deterministic
Circuits using serveral waves on the full footprint, with
framing either SONET or GFP mapped Ethernet.
There is no additional cost to use these capabilities.
They are included in the base connectivity Costs.
There may be call blocking in the use of these
capabilities.
• Long Term Circuits configured as above. There is an
extra cost for these circuits, proportional to bandwidth,
and charged on a day-by-day basis. The shortest
term is one day, and there is no call blocking for these
capabilities.
• Long Term static waves configured and provisioned
for a minimum of a year.
GEANT2 – Internet2 Service Trial
• GEANT2 services include switched, point-topoint GigE-based services
– Bundled as part of core subscription for NRENs
• Internet2 to offer similar services
– Currently via HOPI testbed
– Rollout on NewNet as deployed
• Desire to trial technical and organization
model for making these services available
across both GEANT2 and Internet2
communities
The Details
• July – December 2006: service “trial”
period
– Invite connectors/users in both
communities to request service to
connector/user in the other community
• GEANT2 users: those with access to
GE or wavelength services
• Internet2 community: initial testing on
HOPI; availability on Newnet as rolled
out
Longer-term
• Financial model: costs for service lie
where they fall
– E.g. GEANT2 users follow their cost model
for GEANT2-carried portion; same for
Internet2 service users
– Trans-atlantic costs considered sunk for
now; will examine as understand demand
• Will equip at least two of the 10Gbps
links in place or planned between
Internet2 and GEANT2 to support
