What is UltraLight?
• UltraLight is a program to explore the integration of
cutting-edge network technology with the grid computing
and data infrastructure of HEP/Astronomy
• The program intends to explore network configurations
from common shared infrastructure (current IP networks)
thru dedicated optical paths point-to-point.
• A critical aspect of UltraLight is its integration with two
driving application domains in support of their national and
international eScience collaborations: LHC-HEP and eVLBIAstronomy
• The Collaboration includes:

Some History…
• The UltraLight Collaboration was originally formed in
Spring 2003 in response to an NSF Experimental
Infrastructure in Networking (EIN) RFP in ANIR
• After not being selected, the program was refocused on
LHC/HEP and eVLBI/Astronomy and submitted to “Physics
at the Information Frontier” (PIF) in MPS at NSF
• Collaboration was notified at the end of 2003 that the PIF
program was being postponed 1 year. Suggested that
proposals be redirected to the NSF ITR program.
• ITR Deadline is February 25th, 2004.

eVLBI and UltraLight
• e-VLBI is a major thrust of UltraLight and can directly
complement LHC-HEPs mode of using the network,
allowing us to explore new strategies for network
conditioning and bandwidth management.
• The e-VLBI work under this proposal will be multi-pronged
in an effort to leverage the many new capabilities provided
by UltraLight network and to provide the national and
international VLBI community with advanced tools and
services that are tailored to the e-VLBI application.
• e-VLBI stands to benefit from an UltraLight infrastructure
in numerous ways:
1.
2.
3.
4.
5.
Higher sensitivity
Faster turnaround
Lower costs
Quick diagnostics and tests
New correlation methods
— e-VLBI will provide a different eScience perspective and
validate the operation and efficiency of network
bandwidth sharing between disparate scientific groups

UltraLight Architecture
UltraLight envisions extending and
augmenting the existing grid computing
infrastructure (currently focused on
CPU/storage) to include the network as an
integral component.
A second aspect is
strengthening and
extending “end-toend” monitoring and
planning

Workplan and Phased Deployment
• UltraLight envisions a 4 year program to deliver a new,
high-performance, network-integrated infrastructure:
• Phase I will last 12 months and focus on deploying the
initial network infrastructure and bringing up first services
• Phase II will last 18 months and concentrate on
implementing all the needed services and extending the
infrastructure to additional sites
• Phase III will complete UltraLight and last 18 months.
The focus will be on a transition to production in support of
LHC Physics and eVLBI Astronomy

UltraLight Network
• UltraLight is a hybrid packet- and circuit-switched network
infrastructure employing ultrascale protocols and dynamic
building of optical paths to provide efficient fair-sharing on long
range networks up to the 10 Gbps range, while protecting the
performance of real-time streams and enabling them to coexist
with massive data transfers.
• Circuit switched: “Intelligent photonics” (using wavelengths
dynamically to construct and tear down wavelength paths rapidly
and on demand through cost-effective wavelength routing) are a
natural match to the peer-to-peer interactions required to meet
the needs of leading-edge, data-intensive science.
• Packet switched: Many applications can effectively utilize the
existing, cost effective networks provided by shared packet
switched infrastructure. A subset of applications require more
stringent guarantees than a best-effort network can provide, and
so we are planning to utilize MPLS as an itermediate option
Shawn McKee
HENP SIG • Honolulu, HI • January 25th, 2004
MPLS Topology
• Current network engineering
knowledge is insufficient to
predict what combination of
“best-effort” packet switching,
QoS-enabled packet switching,
MPLS and dedicated circuits will
be most effective in supporting
these applications.
• We will use MPLS and other
modes of bandwidth
management, along with
dynamic adjustments of optical
paths and their provisioning, in
order to develop the means to
optimize end-to-end
performance among a set of
virtualized disk servers, a
variety of real-time processes,
and other traffic flows.

that the system

and optimize
itself while

the details for

Summary and Status
• UltraLight promises to deliver the critical missing
component for future eScience: the integrated,
managed network
• We have a strong team in place, as well as a detailed
plan, to provide the needed infrastructure and
services for production use by LHC turn-on at the
end of 2007
• Currently we are preparing the proposal for ITR
submission by February 25, 2004
• We will need to augment the proposal with additional
grants to enable us to reach our goal of having
UltraLight be a pervasive and effective
infrastructure for LHC physics and eVLBI
Astronomy
