3rd E2E Provisioning Workshop Prague, Czech Republic 29-30 November, 2010 Peter Szegedi, PDO szegedi@terena.org www terena org www.terena.org TERENA TERENA End-to-End (E2E) Provisioning Workshop series 3rd workshop on Applications and Services
Motivations, history 1 t E2E W 1st E2E Workshop in 2008 k h i 2008 1st ”Establishing Lightpaths” 1st ”Establishing Lightpaths” › E-science applications can generate network flows measured in Gb/s, enduring hours, days or even weeks, often between a , g , y , well-defined set of nodes, and with tight constraints on quality of service › The needs of such applications are best met by traffic pp y engineered point-to-point circuits, rather than best effort routed networks like the public Internet. › End-to-end lightpaths (i.e., Gigabit Ethernet circuits or even g p ( , g lambdas) are becoming very important in the service portfolios of NRENs Slide 2
End-to-end networking context NRENs GÉANT NREN NREN Researchers Vendors on networking t ki - Optical networking technologies Researchers - Multi-domain provisioning tools Multi domain provisioning tools on non-networking - Bandwidth on Demand services related topics Slide 3
End-to-end networking context NRENs Local admins GÉANT LAN NREN NREN LAN LAN LAN Researchers Vendors on networking t ki Metro LAN - End user (application) to End user (application) Third-party Researchers - Easy for user to deploy Easy for user to deploy on non-networking - Easy for operator to support related topics - Flexible to existing networks/mechanisms Slide 4
End-to-end networking context NRENs Local admins GÉANT LAN NREN NREN LAN LAN LAN Researchers Vendors on networking t ki Metro LAN - Focusing to the both ends of the connections Third-party Researchers - Challenges on networking level / application level Challenges on networking level / application level on non-networking related topics Slide 5
Outcome of the discussions i t interest areas t 1. Unified/ Standardised network architectures for end-to-end provisioning p g 2. Simplicity of the provisioning processes and software tools › Faster provisioning has still highest priority over dynamic provisioning nowadays › Fast and automated restoration of the broken connections 3. Availability of resources, especially in the last mile End-to-End › Fibre availability, Spectrum efficiency › Access technology (PONs, Ethernet-based platforms), Cost efficiency Provisioning 4. Reliability of point-to-point circuits W orkshop 5. Implication of end-to-end connections on security (firewalling) series aspects, routing integrity and IP addressing issues 6. Operational issues: cooperation between netwrok engineers and application engineers pp g › AuthZ and AuthN, Scheduling, Fairness 7. Business models and cost analyses for end-to-end lightpaths › Commercialization + 1. Facilitating tutorials on the provisioning systems' implementation + 1. Facilitating tutorials on the provisioning systems implementation and usage by the campuses Slide 6

Moving forward… 3 d E2E W 3rd E2E Workshop in 2010 k h i 2010 3rd ”Applications and Services” - There is an issue with the lack of applications requiring e2e connections. - We need to identify the key applications and promote e2e services for end-users. - We should include the application developers/designers. pp p g - We need to deal with real application-to-application services and not just edge-to-edge connection services. - We need to understand the campus policies. - We need attractive business models and we need to understand and explain the cost implications of e2e services for understand and explain the cost implications of e2e services for users.
