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

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
10th June 2004

14
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 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
10th June 2004
HiSEEN Presentation
31
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.
10th June 2004
HiSEEN Presentation
32
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
10th June 2004
HiSEEN Presentation
33
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
10th June 2004
HiSEEN Presentation
34
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
10th June 2004
HiSEEN Presentation
35
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
10th June 2004
HiSEEN Presentation
36
Connectivity Requirements
•Connectivity with commercial
providers for Data Access
•Connectivity with US, Canada and
Japan and southern hemisphere for
Data exchange amongst Centers
10th June 2004
HiSEEN Presentation
37
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
