16Backbone developments
- New router node (11) in Washington DC
- Northern California router node is moving from
Sacramento to Sunnvyale - Houston-Atlanta link upgraded to OC-48c
- Only one link (Seattle-Sacramento) remains at
OC-12c - Increasingly distributed international peering
- Peering with CUDI in Los Angeles (CENIC) and soon
in El Paso (UTEP) - Abilene International Transit Network (ITN) in
production - Collaboration with STARTAP and CANET3
- Backbone and connections were unaffected by
Qwests acquisition of USWEST this summer

18Abilene International Transit Network
- ITN concept developed as some international NRNs
moved their U.S. circuit terminations closer to
the landing points - By default, Abilene international peers are ITN
participants - Non-participating international peers must
indicate this intent to UCAID - Abilene ITN service commenced October 23, 2000
- ITN service currently does not extend to U.S.
federal research and education networks - ESnet, NISN, NREN, DREN, DARPA Supernet
- As an Internet2 backbone, vBNS has become an ITN
participant
19Current Abilene ITN participants (15)
- CANet3
- CERNET
- CUDI
- DFN (via DANTE)
- IUCC
- JANET
- NORDUnet
- RENATER
- REUNA2
- SINET
- SingAREN
- SURFnet
- TANET2
- TransPAC
- vBNS
20Abilene ITN implementation
- BGP communities for international peers
- 115372501 ITN participants
- 115372500 non-ITN participants
- Abilene ITN participants are tagged with ITN
community on ingress (route map TRANSIT-in) - Abilene ITN participants receive all routes with
115372501 community (route map TRANSIT-out)
21BGP considerations for ITN participants
22ITN collaboration
- Abilene, CANet3, and STARTAP are actively
collaborating on international peering and
transit issues in North America - In particular, Abilene and CANet3 have agreed to
provide transit among their respective ITN
participants - Abilene requires a Memorandum of Agreement and an
Interconnection Agreement with the foreign NRN
directly connected to CANet3
23Abilene program changes
- General end of new OC-3c Abilene backbone
connections - Existing and pending OC-3c connections will be
unaffected - Revised fee structure for OC-12c and OC-48c
connections - Objective is to incent bandwidth upgrades for
existing connectors - Overall price reduction is 15
- Encourage Packet-over-SONET (POS) connections
- Expansion to serve the broader educational
community
24Revised Abilene annual connection fees

25Sponsored Education Group Participation
- Effective January 15, 2001, a networked
aggregate of educational institutions may gain
access to Abilene as a Sponsored Education Group
Participant. - designed primarily to accommodate existing and
emerging state-based education networks - reflects modified Abilene CoU
- This new class of Abilene participation
supplements the existing classes of Member
Participant, Collaboration Site, and Sponsored
Participant - Applications will be accepted commencing
1/12/2000
26Advanced service deployment
- Multicast
- fully native deployment using current
inter-domain protocols - PIM-Sparse, MBGP, MSDP
- support for source specific multicast (SSM) in
place - IPv6
- overlay testbed in production
- Quality of Service (QoS)
- QBONE via IETF Differentiated Services protocols
- Abilene premium service testing starting
- Measurement and Network Management
- active probes (Surveyor) deployed in all nodes
- open network management stance
27Building the Network of the Future I
- Upgrade Abilene to a leading-edge optical
transport capability - Transition to OC-192c (10 Gbps) over DWDM
backbone - Explore optical interconnection options with
international networks (e.g., CANet4) leading
GigaPoPs - Establish a rapidly configurable, breakable
Internet2 national testbed for the computer
science research and the advanced network
engineering communities - Interconnection and limited peering with the
DARPA Supernet - Overlay networks (server-based)
- Option of limited-term dedicated capacity via
MPLS tunnels or DWDM ?s
28Network of the Future II
- Continue the vital role of Abilene as a reliable
platform for the development of innovative
applications and the deployment of advanced
services - IP remains the common bearer service
- Position Abilene as a critical component of the
Internet2 End-to-End (e2e) Initiative in
particular, its vital role within the U.S.
research infrastructure - Emphasis on pro-active measurement and open
network management - Increasing dependence on Abilene for next
generation science
29Project NEPTUNE
30Network of the Future - III
- Collaborate with the GigaPoPs on higher
bandwidth attachments and the facilitation of
international peering - Creative, localized solutions often required
above OC-3c - Increasingly distributed set of international
landing points and termination options
31GigaPoPs
- Gigabit-per-second Point of Presence
- OC-12 connectivity or greater (GbEth)
- Regional aggregation point
- high performance (HPNSPs)
- commodity (NSPs)
- Economies of scale
- Member sites
- Value added services shared by members
- Not limited to research universities
- (High-speed) local traffic stays local
32Leading Regional Gigapops

34Importance of carrier hotels
- Facilities where multiple telecommunications
carriers have presences - Orginally exchanged just voice traffic
- Often attract other related businesses ISPs,
Web hosting - Westin Bldg (Seattle), One Wilshire (LA), 60
Hudson (NYC) - Very active area of capital investment in the
U.S. - Leading GigaPoPs establishing presences
- Essential distinguishing factors
- Riser capacity
- Fiber interconnection room (meet-me room)
- Power production and backup
- Ease and speed of construction for tenant
buildout - Local exchange point for peering among ISP
tenants - Dark fiber from the local campuses is very
enabling
