UltraLight Topics

• Introduction: What is the UltraLight Program?

• History

• Program Goals and Details

• Current Status and Summary

Page 3: The UltraLight Program

GNEW 2004 • CERN, Geneva, Switzerland • March 16th, 2004Shawn McKee

• 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 eVLBI-Astronomy

• The Collaboration includes:— Caltech— Florida Int. Univ.— MIT — Univ. of Florida— Univ. of Michigan

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 was February 25th, 2004. We are awaiting word of our proposal status…

LHC Physics will require large bandwidth capability over a globally distributed network. The HENP Bandwidth Roadmap is shown in the table below:

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. Higher sensitivity2. Faster turnaround3. Lower costs4. Quick diagnostics and tests5. 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-to-end” monitoring and planning

Workplan and Phased Deployment

• UltraLight 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 UltraLightUltraLight 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 intermediate option

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.

Logical Diagram of UltraLight Grid Enabled Analysis

• An “UltraLight” user’s perspective of the system:

Important to note that the system helps interpret and optimize itself while “summarizing” the details for ease of use

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 awaiting the results of the ITR process• 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
