Outline The question: i. Grid showed impressive science that used a custom built network. What happened behind the scenes to make it happen? With some background information: What is i. Grid and how it has evolved. What is this optical networking about. The answer: Where, who and how the i. Grid 2005 infrastructure took shape. i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
What is i. Grid? The official web sites www. igrid 2005. org contains the mission statement: the 4 th community-driven biennial International Grid event, is a coordinated effort to accelerate the use of multi-10 Gb international and national networks, to advance scientific research, and to educate decision makers, academicians and industry researchers on the benefits of these hybrid networks. i. Grid 2005 Cyber-Infrastructure Three key points: - community driven - multi-10 Gb networks - hybrid networks Feb. 27 2006 ON*VECTOR Photonics Workshop
History of previous i. Grids The themes were already there from the beginning… i. Grid 1998: Empowering Global Research Community Networking Applications and technologies depend on end-to-end delivery of multi-tens-ofmegabits bandwidth with quality of service control, and need the capabilities of emerging Internet protocols for resource control and reservation. i. Grid 2000: An International Grid Application Research Demonstration at INET 2000 Demonstrate how the power of todays’ research networks enables access to remote computing resources, distribution of digital media, and collaboration with distant collegues. i. Grid 2002: The International Virtual Laboratory Demonstrate application demand for increased bandwidth. i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Lambda networking The i. Grid 2005 cyber-infrastructure provided a lambda networking facility to demonstrators. In the scientific arena, lambda networking indicates: - use of different light wavelengths (i. e. light paths) to provide independent services over the same strand of optical fiber - creation of dedicated and application-specific paths Main lambda networking characteristics of the i. Grid setup: - broad international connectivity large available bandwidth (user driven) light path provisioning reconfigurable and flexible setup i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Where and when? The event took place: in the Cal. IT 2 building in the UCSD campus in San Diego; between Sep. 26 -29 September 2005. Challenge: the building inauguration had not yet taken place: the network was built while the building was being finished up. i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
What and who? There were two main activities: demonstrations and symposium sessions.

Demos requirements The guiding principle: ask what they want, and sometimes tell them what they need. A - questionnaire that tried to understand the demos’ needs for: On-site computers, data storage and visualization displays Remote computers and storage Software Special-purpose equipment Audio Networking topology i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Demo stations The demos were distributed across 4 spaces: Tera. Scale Room Cave Room Multipurpose Room Auditorium 3 demo stations: 2 demo stations: Rice: 2 -Panel display Couts: C-Wall Sessions: Stereo Projection Goodhue: 2 -Panel Display Spreckels: 100 Mpixel Bandini: Side-by-side Proj.

Grid 2005 Cyber-Infrastructure Harrison: Side-by-side Projection Feb. 27 2006 ON*VECTOR Photonics Workshop
Onsite resources Two of the jewels: Tiled Display: 11 x 5 tiled display of NEC 20” 1600 x 1200 LCD panels i. Grid 2005 Cyber-Infrastructure Sony 4 k Projection Feb. 27 2006 ON*VECTOR Photonics Workshop
Onsite resources (II) Another way to look at it: 24 10 GE ports: - 5 interfaces for common infrastructure equipment: 3 x 10 GE nodes, 2 x 10 GE ports for HP switch used for the Tiled Display in Spreckels - 19 interfaces for demonstrator equipment, network switches and nodes 11 1 GE fiber ports: - 11 to demonstrator equipment, network switches and nodes 53 1 GE copper ports: - 19 for common infrastructure equipment 34 for demonstrators equipment i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Sun. Light To satisfy the needs of the demos: Sun. Light, the optical exchange built for i. Grid at Cal. IT 2. Ingredients: - Lots (lots!) of planning. - Committees members met several times before the workshop time - Network equipment donated by vendors: - Cisco, Force 10, Nortel primarily - Setup in the weeks preceding the workshop - Circuits delivery and installation i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop

External connectivity From Sun. Light: 10 x 10 gbps = 100 gbps available to the demonstrators. (Side note: during i. Grid 2002 it was 1 x 10 GE) Some paths to be mentioned: Cave. Wave link to Chicago, used for many of the visualization demos. Layer 1 circuits - few. Layer 2 circuits - the majority. Layer 3 circuits - for the routed connectivity. i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Layer 1/2 int’l connectivity i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Layer 1/2 int’l connectivity (II) An international effort to reach the demonstrators’ countries: Asia - China, Korea, Japan, Taiwan North America - Canada, Mexico, US Europe - Czech Republic, Netherlands, Poland, Spain, UK A central role played by the various optical exchanges: Pacific. Wave in Seattle KRLight in Seoul T-LEX in Tokyo Star. Light/Trans. Light in Chicago MANLAN in New York Nether. Light in Amsterdam UKLight in London CZLight in Prague Northern. Light in Stockholm i. Grid 2005 Cyber-Infrastructure … all part of the GLIF. The GLIF meeting followed i. Grid Feb. 27 2006 ON*VECTOR Photonics Workshop
Layer 3 infrastructure i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Routing Did I hear well? … Not surprising: routing is a component in hybrid networks. Routing needed: Internet connectivity to demonstrators, via commodity peering from UCSD and connection to major NRENs; Demos using Layer 3 paths via NRENs; Routing in Sun. Light to direct multiple demos to shared resources , for example to Tiled Display. i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
The NOC Committee members and vendor engineers provided the NOC support during the workshop. The NOC: - setup the infrastructure: racking, pulling fibers configure the equipment provide continuing support to the demonstrators The biggest challenge: - automatic versus manual configuration. scheduling of common links Missing: the user/application _really_ configuring the light paths. Not all demos were “NOC-independent” after the kick-off. i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Light paths What is in a name? For every demonstrator light paths meant something else: - optical path without L 2 or L 3 services; - L 2 path over completely dedicated circuits, with possible need for scheduling; - L 2 path over shared link (coexisting demos); - Mix of L 3 and L 2 features. For each demo the NOC needed to do the “translation” among the various meaning. i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
“Dutch” lightpaths An easy way to see this: 4 demos with a Dutch label NL 101, NL 102, NL 103, NL 104… NL 101/2 VM Turntable, Token-based network element access control and path selection AMS NY NL 103 IPv 4 Link-local addressing for optical networks IRNC link CHI SEA Effort? … High. SAN i. Grid 2005 Cyber-Infrastructure AMS VLAN NL 103 CHI Cave. Wave link NL 104 Dead cat demo VLAN NL 103 SAN Effort? … Medium. VLAN configuration Difficult when L 2 is multidomain Routed Internet SAN Effort? … Low. Routing does It all but performance Needs to be tuned. Feb. 27 2006 ON*VECTOR Photonics Workshop
Just after i. Grid: SC 05 Using the experience gained in September, many tried again. i. Grid 2005 Cyber-Infrastructure Feb. 27 2006 ON*VECTOR Photonics Workshop
Lessons learned 1. It was a lot of work, but the achievements were rewarding. 2. Global lambdas are a reality and a need. 3. The community is focusing on the tools for automatic engineering and setup needed on hybrid networks. Submitted an article on the topic: The network infrastructure at i.
