Research & Education
Universities strive for qualitative and quantitative
improvements:
• In support of research
• In support of teaching and learning
how to accelerate the change in technologies and
applications on the internet to support new demands
for the research and education community?
how can new technologies be incorporated into the
existing Internet? (think back in when the Internet
started…)

Abilene: Partnership approach
The Abilene Network is a UCAID project done in
partnership with
• Cisco Systems (routers, switches, and access)
• Juniper Networks (routers)
• Nortel Networks (SONET kit)
• Qwest Communications (SONET & DWDM circuits,
co-location)
• Indiana University (network operations center)
• Internet2 Test & Evaluation Centers (ITECs)
– North Carolina and Ohio
16
Abilene – October, 2002
IP-over-DWDM (OC-192c) and IP-over-SONET
backbone (OC-48c)
50 direct connections (OC-3c  10-Gbps)
• 4 (soon 6) OC-48c & 1 Gig Eth connections
• 2 10-Gbps (10 Gig Eth) connections pending
– OC-192 SONET also supported
• 23 connections at OC-12c or higher
• Number of ATM connections soon down to 7
219 participants – research univs. & labs
• All 50 states, District of Columbia, & Puerto Rico
Expanded access
• 54 sponsored participants and 25 state education networks
17
Next Generation Abilene
•Partnership with Qwest extended thru 2006
•Juniper T640 routers selected for backbone
• 10/11 next generation router nodes in place; 12th location pending
– 2 racks in each location (Juniper T640 router & 4 measurement servers)
– OC-48c SONET interconnects to Cisco 12008 routers
– Very pleased to date with new router performance and interoperability
with 1st generation backbone
•10-Gbps backbone  deployment has started this Fall
• Transcontinental 10-Gbps ’s:
6 ’s connected to network
– DC-NYC-Chicago-Indy-KC-Sunnyvale CA-Los Angeles
– First  outage (3.5 hours): fiber cut in NYC
– ITEC network performance validation test: 8 Gbps of 2-way traffic (v4
and v6 mix) transmitted without loss or reordering – Sunnyvale to San
Diego
19
Next Generation Abilene – more
•Incremental, non-disruptive transition
Upgrade Schedule Overview
• Aug/Sep – New backbone routers installed
• Sep/Oct – ‘First wave’ turn-up
• Fall 2002 – Connector & peer circuits migrated to new
routers
• 2003 – Remaining 10-Gbps ’s commissioned
•Advanced service foci
– Native, high-performance IPv6
– Enhanced, differentiated measurement
– Rapid restoration for resiliency
20
Native IPv6 deployment
•Abilene is now running native IPv6 over the entire Cisco
12008 and Juniper T640 backbone
• Dual stack mode
• IS-ISv6 used for internal routing
•Significant number of peers and connectors already have
converted
•Tunnel support consolidated
• IU-NOC provides support for existing tunnels; Not accepting any new
tunnels
•Abilene provided addressing
• 2001:468::/35 from ARIN for participants – 63% allocated
• 3ffe:3700::/24 from 6bone for SEGP / sponsored users
•Native IPv6 (UCSD iGrid demo: 400 Mbps v6 SD-AMS)
•Kudos to Abilene NOC, IPv6 WG, Cisco, and Juniper

More key aspects of next
generation Abilene backbone - I
Resiliency
• Moving from SONET rings to unprotected ’s is significant
• Collaboration apps demand convergence times of ~100 ms
• Faster converging IP-based IGP as ultimate solution
– v4 unicast IGP switch from OSPF to IS-IS
Differentiated measurement capabilities
• Starting w/four dedicated servers at each node
– Local data collection to capture data at times of network instability
• Enhance active probing
– Now: latency & jitter, loss, reachability (Surveyor)
– Regular TCP/UDP throughput tests – ~1 Gbps
• Separate server for E2E performance beacon
• Enhance passive measurement
– Now: SNMP (NOC) & traffic matrix/type (Netflow)
– Routing (BGP & IGP)
– Optical splitter taps on backbone links at select location(s)

Optical networking technology
drivers
Computational science: emerging interdiscipline
• Now: Bandwidth + distributed data sensing and storage
• Increasingly distributed data collection and storage
• NSF Distributed Terascale Facility: TeraGrid Project
At end of aggressive period of fiber construction on the
national & metro scales in U.S.
• Now rapid industry contraction, capital crisises, bankruptcies
• Glut of conduit and fiber, but not of bandwidth
Many university campuses and regional GigaPoPs already
use dark fiber
• Much metro DWDM/GigE and some regional (state based)
DWDM
Optical transport is the focus with switching on horizon
30
U.S. R&E optical networking
scaling factors
11 Next Generation Abilene routers
~50 Abilene connectors
~220 Abilene participants
• Research universities & labs
But…
30-60 DWDM access nodes in leading
viable carriers’ U.S. networks
31
Regional optical fanout
In the next generation architecture, regional &
state based optical networking projects are
critical
Three-level hierarchy remains vital
• National backbone, GigaPoPs (ARNs), Campuses
Close collaboration with the GigaPoPs
• Regional Optical Networking project
U.S. carrier DWDM access is now not nearly
as widespread as with SONET circa 1998
• 30-60 cities for DWDM
• ~120 cities for SONET
32
UCAID objectives for national
fiber optical networking facility
1.
With partners, help build and operate a world-class,
national-scale optical networking facility
•
•
•
2.
Serve all of higher education
•
3.
p2p ’s
IP/optical experimentation & protocol development
Operational requirements (over time)
Coordinate closely with regional optical networking
initiatives (Quilt RONCO project)
Focus on optical transport initially
Continue to examine prospects for a national fiber optical
networking facility with key partners

VLBI - Very Long Baseline
Interferometry
Astronomers collect data about a star
from many different earth based
antennae and send the data to a
specialized computer for analysis
on a 24x7 basis.
VLBI is not as concerned with data
loss as they are with long term
stability.
The end goal is to send data at
1Gb/s from over 20 antennae that
are located around the globe.
Interesting:
Successfully ran 788 Mbps

sites in U.S. Working on

their ability to run data to
