  4. The European Space Agency Funded in 1969 15 members states ESTEC ESOC HQ ESRIN The European Space Agency promotes the exploration and development of space activities in Europe The member states can perform more ambitious programmes while combining their know-how and financial resources HiSEEN Presentation

  5. The European Space Agency HUBBLE (1990) Universe exploration SOHO (1995) • Increase the knowledge of the: • solar system and universe • Earth and its environment Sun observation • Develop technologies based in the satellites use MARS ESPRESS (2003) Looking for live signs in Mars • Promote the European industry activities COLUMBUS (2004) Scientific laboratory for the ISS ARTEMIS (2001) New telecommunication technologies GALILEO (2004, 2008) The European satellite navigation system ERS (1991,1995), ENVISAT (2002) Earth Study Which are the ESA activities ?

  14. Online Data Access Objectives • The EO products shall be distributed electronically to the end users located around the world • The EO data (Raw, and level 1 products) shall be primarily distributed in the Payload Data Segment electronically • Phase 1 – 2004 • On-demand products distribution • Electronic data circulation between centres • Phase 2 – 2005 • Interactive online data request and retrieval • Integration of non-ESA missions HiSEEN Presentation

  15. Basic Principles • On-line Archive: Mass Storage Tape Libraries or on disk • User data request via Internet (order or subscription) • Product retrieval via Internet: • High speed Internet backbone (GEANT/NREN) • ISP augmented with load-balancing and re-routing COTS • Product distribution via Satellite • Electronic data distribution between GS Centers using High Speed Intranet VPN (based on GEANT/NREN) • Security • Detect and avoid unauthorized use of EO data • User authentication • Standard COTS encryption (IP VPN) • Accounting of data downloaded • Protection from malicious intrusion • ESA Network Security policy as baseline with Intrusion Detection System 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 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. 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 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 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 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 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 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 HiSEEN Presentation

  39. Discussion and Way forward HiSEEN Presentation
