Optical Networking & Grid Middleware Final Presentation May 25, 2004

Outline Introduction Designed Network Test Network Switching Configuration Grid Computing Conclusion

Why this project?  Project all is about setting up testbeds over which research in various directions can be conducted o Some of the problems to be solved by these researches is shown in the following clip...

The Video: Part I

Project Goals Connect the TSLab/SCINT joint testbed to PDC and the Global Optical Research Network using MENTIS 3000 network elements and Juniper M-series routers. Configure label switching on above network Setup a grid computing testbed and study the AAA of mobile users using grid middleware

Outline Introduction Designed Network Test Network Switching Configuration Grid Computing Conclusion

Designed Network Components Equipment provided: Mentis 3000 NE and Juniper M-Series routers Live Network: SCINT / TSLab / KistaIP Networks to connect: KTHNOC / PDC / Amsterdam IX

Outline Introduction Designed Network Test Network Switching Configuration Grid Computing Conclusion

Lumentis Mentis 3000 NE Optical crossconnect –Single mode –Software controlled Wavelength multiplexing –DWDM Protocol transparent –Transceivers

Juniper M-series routers Router with routing engine Support RSVP/MPLS/GMPLS

Linux MPLS More routers were needed Linux MPLS –Cheap / Uses standard hardware –No support of MPLS by default –Requires patching the kernel source and recompiling the kernel Easier said than done!

Outline Introduction Designed Network Test Network Switching Configuration Grid Computing Conclusion

R1: Ingress router R2,R3,R4: Transit routers R6: Penultimate router R8: Egress router Review of MPLS

Types of LSPs Two types are configured on testbed –Static LSPs –Signaled LSPs (RSVP/CR-LDP) Label removal behavior –Penultimate hop popping –Ultimate hop popping

GMPLS Configuration Steps –LMP configurations LMP TE links LMP Peers – MPLS configurations MPLS Path MPLS LSP

Why not on testbed? GMPLS signaling requires strict paths –Strict path defined by listing all transit routers Mentis 3000 NE does not yet support GMPLS

Outline Introduction Designed Network Test Network Switching Configuration Grid Computing Conclusion

Grid Computing Testbed Fully functional Middleware: The Globus Toolkit (v2.4) Testbed portal: Gridscape Testbed to be extended to PDC

AAA of mobile users with grid middleware Middleware security based on the Grid Security Infrastructure (GSI) –Based on public key cryptography –Proxy certificates (delegation/single sign- on) PKI based has advantages

System Operation common server and user mutually authenticate each other User delegates the common server to contact the firewall control software After mutual authentication, firewall control software opens up a rule for user

Outline Introduction Designed Network Test Network Switching Configuration Grid Computing Conclusion

Conclusion: Achievements Design of network that connects the TSLab/SCINT joint testbed to PDC and the Global Optical Research Network DWDM based test setup with different types of label switching configured Grid computing testbed, web portal Design of a AAA scheme for mobile user authentication

Conclusion: Future Tasks Extend testbed to provide connectivity to Amsterdam OIX MPLS Linux interoperability testing and GMPLS configuration Investigate GSI AAA implementation aspects Joint testbed with Acreo
