2. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Outline The question: iGrid showed impressive science that used a custom built network. What happened behind the scenes to make it happen? With some background information: What is iGrid and how it has evolved. What is this optical networking about. The answer: Where, who and how the iGrid 2005 infrastructure took shape.

3. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure What is iGrid? The official web sites www.igrid2005.org contains the mission statement: the 4th community-driven biennial International Grid event, is a coordinated effort to accelerate the use of multi-10Gb international and national networks, to advance scientific research, and to educate decision makers, academicians and industry researchers on the benefits of these hybrid networks. Three key points: - community driven - multi-10Gb networks - hybrid networks

4. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure History of previous iGrids The themes were already there from the beginning… iGrid1998: Empowering Global Research Community Networking Applications and technologies depend on end-to-end delivery of multi-tens-of- megabits bandwidth with quality of service control, and need the capabilities of emerging Internet protocols for resource control and reservation. iGrid2000 : An International Grid Application Research Demonstration at INET2000 Demonstrate how the power of todays’ research networks enables access to remote computing resources, distribution of digital media, and collaboration with distant collegues. iGrid2002: The International Virtual Laboratory Demonstrate application demand for increased bandwidth.

5. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Lambda networking The iGrid2005 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 iGrid setup: -broad international connectivity -large available bandwidth -(user driven) light path provisioning -reconfigurable and flexible setup

6. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Where and when? The event took place: in the CalIT2 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.

7. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure What and who? There were two main activities: demonstrations and symposium sessions. Over 300 participants …plus the committee members. Demonstrations A global effort: - 49 demonstrations; - 12 countries as main demo contacts; - 20 participating countries; - 4 continents. Symposium In the auditorium: - 6 keynote speakers; - 12 panels sessions; - 3 master classes.

10. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure 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

11. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Demo stations The demos were distributed across 4 spaces: TeraScale Room Cave Room Multipurpose Room Auditorium 3 demo stations: Rice: 2-Panel display Goodhue: 2-Panel Display Quin: 4-Panel display 3 demo stations: Couts: C-Wall Spreckels: 100 Mpixel Bushyhead: 3D Auto-stereo 2 demo stations: Sessions: Stereo Projection Bandini: Side-by-side Proj...plus Research Channel 2 demo stations: Swing: Sony 4K Projections Harrison: Side-by-side Projection

12. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Onsite resources Two of the jewels: Tiled Display: 11x5 tiled display of NEC 20” 1600x1200 LCD panels Sony 4k Projection

13. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Onsite resources (II) Another way to look at it: 24 10GE ports: -5 interfaces for common infrastructure equipment: 3 x10GE nodes, 2 x 10GE ports for HP switch used for the Tiled Display in Spreckels -19 interfaces for demonstrator equipment, network switches and nodes 11 1GE fiber ports: - 11to demonstrator equipment, network switches and nodes 53 1GE copper ports: -19 for common infrastructure equipment -34 for demonstrators equipment

14. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure SunLight To satisfy the needs of the demos: SunLight, the optical exchange built for iGrid at CalIT2. Ingredients: -Lots (lots!) of planning. -Committees members met several times before the workshop time -Network equipment donated by vendors: -Cisco, Force10, Nortel primarily -Setup in the weeks preceding the workshop -Circuits delivery and installation

16. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure External connectivity From SunLight: 10 x 10gbps = 100gbps available to the demonstrators. (Side note: during iGrid2002 it was 1 x 10GE) Some paths to be mentioned: CaveWave link to Chicago, used for many of the visualization demos. Layer1 circuits - few. Layer2 circuits - the majority. Layer3 circuits - for the routed connectivity.

17. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Layer1/2 int’l connectivity

The GLIF meeting followed iGrid

19. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Layer3 infrastructure

20. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure 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 Layer3 paths via NRENs; Routing in SunLight to direct multiple demos to shared resources, for example to Tiled Display.

21. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure 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.

22. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure Light paths What is in a name? For every demonstrator light paths meant something else: -optical path without L2 or L3 services; -L2 path over completely dedicated circuits, with possible need for scheduling; -L2 path over shared link (coexisting demos); -Mix of L3 and L2 features. For each demo the NOC needed to do the “translation” among the various meaning.

23. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure “Dutch” lightpaths An easy way to see this: 4 demos with a Dutch label NL101,NL102, NL103, NL104… NL101/2 VM Turntable, Token-based network element access control and path selection NL103 IPv4 Link-local addressing for optical networks NL104 Dead cat demo Effort?… Medium. VLAN configuration Difficult when L2 is multi- domain Effort?… Low. Routing does It all but performance Needs to be tuned. Effort?… High.

25. Feb. 27 2006 - ON*VECTOR Photonics Workshop iGrid 2005 Cyber-Infrastructure 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.
