HENP Lambda Grids:
Fibers for Physics
 Problem: Extract “Small” Data Subsets of 1 to 100 Terabytes
from 1 to 1000 Petabyte Data Stores
 Survivability of the HENP Global Grid System, with
hundreds of such transactions per day (circa 2007)
requires that each transaction be completed in a
relatively short time.
 Example: Take 800 secs to complete the transaction. Then
Transaction Size (TB)
Net Throughput (Gbps)

 Summary: Providing Switching of 10 Gbps wavelengths
within ~2-4 years; and Terabit Switching within 5-8 years
would enable “Petascale Grids with Terabyte transactions”,
to fully realize the discovery potential of major HENP programs,
as well as other data-intensive research.

 Main Report: “Networking for HENP” [H. Newman et al.]
 Includes Brief Updates on Monitoring, the Digital Divide
and Advanced Technologies [*]
 A World Network Overview (with 27 Appendices):
Status and Plans for the Next Few Years of National &
Regional Networks, and Optical Network Initiatives
 Monitoring Working Group Report

August 2004 Update Reports at the SCIC Web Site:
See http://icfa-scic.web.cern.ch/ICFA-SCIC/documents.htm
 Asia Pacific, Latin America, GLORIAD (US-Ru-Ko-China);
Brazil, Korea, etc.
SCIC Main Conclusion for 2003
Setting the Tone for 2004
 The disparity among regions in HENP could increase
even more sharply, as we learn to use advanced networks
effectively, and we develop dynamic Grid systems in the
most favored” regions
 We must take action, and work to Close the Digital Divide
 To make Physicists from All World Regions Full
Partners in Their Experiments; and in the Process
of Discovery
 This is essential for the health of our global
experimental collaborations, our plans for future
projects, and our field.
ICFA Report: Networks for HENP
General Conclusions (2)
 Reliable high End-to-end Performance of networked applications such as
large file transfers and Data Grids is required. Achieving this requires:
 End-to-end monitoring extending to all regions serving our community.
A coherent approach to monitoring that allows physicists throughout
our community to extract clear information is required.
 Upgrading campus infrastructures.
These are still not designed to support Gbps data transfers in most HEP
centers. One reason for under-utilization of national and Int’l backbones,
is the lack of bandwidth to end-user groups in the campus.
 Removing local, last mile, and nat’l and int’l bottlenecks
end-to-end, whether technical or political in origin.
While National and International backbones have reached 2.5 to 10 Gbps
speeds in many countries, the bandwidths across borders, the
countryside or the city may be much less.
This problem is very widespread in our community, with
examples stretching from the Asia Pacific to Latin America
to the Northeastern U.S. Root causes for this vary, from lack
of local infrastructure to unfavorable pricing policies.

 Capability: 4 to Hundreds of Times; Much Faster than Moore’s Law
Proliferation of 10G links across the Atlantic Now; Will Begin use of
Multiple 10G Links (e.g. US-CERN) Along Major Paths by Fall 2005
 Direct result of Falling Network Prices: $ 0.5 – 1M Per Year for 10G
Ability to fully use long 10G paths with TCP continues to advance:
7.5 Gbps X 16kkm (August 2004)
Technological progress driving equipment costs in end-systems lower
 “Commoditization” of Gbit Ethernet (GbE) ~complete: ($20-50 per port)
10 GbE commoditization (e.g. < $ 2K per NIC with TOE) underway
Some regions (US, Europe) moving to owned or leased dark fiber
Emergence of the “Hybrid” Network Model: GNEW2004; UltraLight, GLIF
Grid-based Analysis demands end-to-end high performance & management
The rapid rate of progress is confined mostly to the US, Europe, Japan and
Korea, as well as the major Transatlantic routes; this threatens to cause
the Digital Divide to become a Chasm
Work on the Digital Divide:
Several Perspectives
 Work on Policies and/or Pricing: pk, in, br, cn, SE Europe, …

APAN Recommendations
(at July 2004 Meeting in CAIRNS, Au)
Central Issues for APAN this decade
 Stronger linkages between applications and infrastructure neither can exist independently
 Stronger application and infrastructure linkages among APAN
members.
 Continuing focus on APAN as an organization that represents
infrastructure interests in Asia
 Closer connection between APAN the infrastructure &
applications organization and regional political organizations
(e.g. APEC, ASEAN)
New issues demand attention
 Application measurement, particularly end-to-end network
performance measurement is increasingly critical (deterministic
networking)
 Security must now be a consideration for every application and
every network.

AFRICA: Key Trends
M. Jensen and P. Hamilton Infrastructure Report, March 2004
 Growth in traffic and lack of infrastructure Predominance of Satellite;
But these satellites are heavily subscribed
 Int’l Links: Only ~1% of traffic on links is for Internet connections;
Most Internet traffic (for ~80% of countries) via satellite
 Flourishing Grey market for Internet & VOIP traffic using VSAT dishes
 Many Regional fiber projects in “planning phase” (some languished in
the past); Only links from South Africa to Nimibia, Botswana done so far
 Int’l fiber Project: SAT-3/WASC/SAFE Cable from South Africa to Portugal
Along West Coast of Africa
 Supplied by Alcatel to Worldwide Consortium of 35 Carriers
 40 Gbps by Mid-2003; Heavily Subscribed. Ultimate Capacity 120 Gbps
 Extension to Interior Mostly by Satellite: < 1 Mbps to ~100 Mbps typical
Note: World Conference on Physics and Sustainable Development,
10/31 – 11/2/05 in Durban South Africa; Part of World Year of Physics 2005.
Sponsors: UNESCO, ICTP, IUPAP, APS, SAIP
AFRICA: Nectar Net Initiative
Growing Need to connect academic researchers, medical
researchers & practitioners to many sites in Africa
Examples:
 CDC & NIH: Global AIDS Project, Dept. of Parasitic Diseases,




Nat’l Library of Medicine (Ghana, Nigeria)
Gates $ 50M HIV/AIDS Center in Botswana; Project Coord at Harvard
Africa Monsoon AMMA Project, Dakar Site [cf. East US Hurricanes]
US Geological Survey: Global Spatial Data Infrastructure
Distance Learning: Emory-Ibadan (Nigeria); Research
Channel Content
But Africa is Hard: 11M Sq. Miles, 600 M People, 54 Countries
 Little Telecommunications Infrastructure
Approach: Use SAT-3/WASC Cable (to Portugal), GEANT
Across Europe, Amsterdam-NY Link Across the Atlantic,
then Peer with R&E Networks such as Abilene in NYC
 Cable Landings in 8 West African Countries and South Africa

 Pragmatic approach to reach end points:
VSAT satellite, ADSL, microwave, etc.

HENP Data Grids, and Now
Services-Oriented Grids
 The original Computational and Data Grid concepts are
largely stateless, open systems
 Analogous to the Web
 The classical Grid architecture had a number of implicit
assumptions
 The ability to locate and schedule suitable resources,
within a tolerably short time (i.e. resource richness)
 Short transactions with relatively simple failure modes
 HENP Grids are Data Intensive & Resource-Constrained
 Resource usage governed by local and global policies
 Long transactions; some long queues
 Analysis: 1000s of users competing for resources
at dozens of sites: complex scheduling; management
 HENP Stateful, End-to-end Monitored and Tracked Paradigm
 Adopted in OGSA [Now WS Resource Framework]

ICFA, understanding the vital role of these issues
for our field’s future, commissioned the Standing
Committee on Inter-regional Connectivity (SCIC) in
1998, to survey and monitor the state of the
networks used by our field, and identify problems.
For the past three years the SCIC has focused on
understanding and seeking the means of reducing
or eliminating the Digital Divide, and proposed to
ICFA that these issues, as they affect our field of
High Energy Physics, be brought to our community
for discussion. This led to ICFA’s approval, in July
2003, of the Digital Divide and HEP Grid Workshop.

 “IHEP is working with the Computer Network Information Center
(CNIC) and other universities and institutes to build Grid
applications for the experiments. The computing resources and
storage management systems are being built or upgraded in the
Institute. IHEP has a 100 Mbps link to CNIC, so it is quite easy to
connect to GLORIAD and the link could be upgraded as needed.”
