HENP SIG Austin, TX September 27th, 2004 Shawn McKee UltraLight Topics Introduction: What is the UltraLight Program? History Program Goals and Details Current Status and Summary

HENP SIG Austin, TX September 27th, 2004 Shawn 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 What is UltraLight? ― UC Riverside ― BNL ― FNAL ― SLAC ― UCAID/Internet2

HENP SIG Austin, TX September 27th, 2004 Shawn McKee 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 25 th, We were selected for funding and official started on September 15, 2004!

HENP SIG Austin, TX September 27th, 2004 Shawn McKee HENP Network Roadmap LHC Physics will require large bandwidth capability over a globally distributed network. The HENP Bandwidth Roadmap is shown in the table below:

HENP SIG Austin, TX September 27th, 2004 Shawn McKee 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

HENP SIG Austin, TX September 27th, 2004 Shawn McKee Workplan and Phased Deployment UltraLightUltraLight 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 UltraLightPhase 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

HENP SIG Austin, TX September 27th, 2004 Shawn McKee UltraLight Network: PHASE I Implementation via “sharing” with HOPI/NLR MIT not yet “optically” coupled

HENP SIG Austin, TX September 27th, 2004 Shawn McKee UltraLight Network: PHASE II Move toward multiple “lambdas” Bring in BNL and MIT

HENP SIG Austin, TX September 27th, 2004 Shawn McKee UltraLight Network: PHASE III Move into production Optical switching fully enabled amongst primary sites Integrated international infrastructure

HENP SIG Austin, TX September 27th, 2004 Shawn McKee 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

HENP SIG Austin, TX September 27th, 2004 Shawn McKee UltraLight Optical Exchange Point L1, L2 and L3 services Interfaces —1GE and 10GE —10GE WAN-PHY (SONET friendly) Hybrid packet- and circuit-switched PoP —Interface between packet- and circuit-switched networks Control plane is L3 Locations: Los-Angeles, Geneva, Chicago (in the future)

HENP SIG Austin, TX September 27th, 2004 Shawn McKee 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.

HENP SIG Austin, TX September 27th, 2004 Shawn McKee MPLS deployment Compute path from one given node to another such that the path does not violate any constraints (bandwidth/administrative requirements) Ability to set the path the traffic will take through the network (with simple configuration, management, and provisioning mechanisms) —Take advantage of the multiplicity of waves/L2 channels across the US (NLR, HOPI, Ultranet and Abilene/ESnet MPLS services) VPLS: Single broadcast domain for users who want to deploy their own L2 private network EoMPLS will be used to build layer2 paths ?? natural step toward the deployment of GMPLS ??

HENP SIG Austin, TX September 27th, 2004 Shawn McKee SC2004Targets: è 100 Gbps of aggregated throughput to Caltech & SLAC/FNAL booths è 1-2 GByte/s of disk to disk transfers.

HENP SIG Austin, TX September 27th, 2004 Shawn McKee 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 ramping up to “turn on” UltraLight The SC2004 demo will help jumpstart UltraLight and provide a glimpse of what we hope to enable We plan to augment the proposal thru additional grants to enable us to reach our goal of having UltraLight be a pervasive and effective infrastructure for LHC physics
