31. 10 th June 2004 HiSEEN Presentation 31 HiSEEN Implementation Challenges Several and different contracts and prizing policy to manage Different approaches in procurement phase –Direct via NRENs –Indirect via 3rd Party (SSC, KSAT) Complex interface with national TELCO –changes from country to country –difficult in some locations Different technology for Access Routers to be procured and configured –ATM, F/G-Ethernet, E3/G.703

32. 10 th June 2004 HiSEEN Presentation 32 Implementation Challenges In few words: –A new NREN is another small new project with consequent cost –fortunately the implementation challenges are “one off” –unfortunately some of the issues remain over time during the operational phase.

33. 10 th June 2004 HiSEEN Presentation 33 HiSEEN Operational Challenges Operations are carried by the ESANOC as for the ESACOM –ESANOC Team located in Italy interface with: NRENS, customer, implement changes, manage the network and related IT Infrastructure perform the administrative day to day tasks “One to many” interface with NRENs is complex Interfacing with different NREN implies: –Learning different operational procedures for handling: trouble ticket / troubleshooting maintenance changes management –often using different languages

34. 10 th June 2004 HiSEEN Presentation 34 HiSEEN Operational Challenges Not all NRENs provide the same services Different access to important information likes: Network Maps Tools for bandwidth utilization Tools for link health status Access to router configurations

35. 10 th June 2004 HiSEEN Presentation 35 Services that not all NRENs provide Tools for: –access link bandwidth utilization –link health –logical and geographical network maps and information related to utilization and available bandwidth. Notification services to the customer: –planned outages, –detected faults –foreseen time to recover Burst rate options rather than pure committed fixed rate

36. 10 th June 2004 HiSEEN Presentation 36 Issues for discussion A “more standard” interface for the customer rather then different interfaces End-to-end QoS –Today maybe possible only by direct agreement between 2 NRENs. Service Level Agreement (SLA) for: –performance –availability –time to repair – etc… Quick time for bandwidth adaptation –E.g. time commitment for increase of capacity

37. 10 th June 2004 HiSEEN Presentation 37 Connectivity Requirements Connectivity with commercial providers for Data Access Connectivity with US, Canada and Japan and southern hemisphere for Data exchange amongst Centers

38. 10 th June 2004 HiSEEN Presentation 38 Policy and Limitations to use the NREN/GEANT network? Earth Observation scenarios –Data: ESA or other space agencies missions Dual use missions Value-adding data for service provision EO Commercial missions (I.e.: SPOT, Ikonos –Data source: ESA centres hosted at ESA or other establishments Research institutes Public organisations Commercial centres –Destination / users Scientific users Experimental value-adding Public value-adding service providers Commercial value-adding service providers Defense
