Use of Network Infrastructure in Earth Observation
GSCB Workshop #2, ESRIN 18-19 June 2009 G. Buscemi (ESA)
Use of the Network infrastructure for the Earth Observation Community
Electronic circulation of data and auxiliary data
Transfer of planning and M&C data
User access to the EO products catalogues for consulting and ordering
Data dissemination and distribution to EO users (Internet based applications and Satellite dissemination)
Remote access to EO PDGS systems for operation and maintenance
Virtual organization
Data Relay

EO Networks Drivers (1)• Highly Available and robust system (e.g. Availability
of Sentinels GS around 99.5%)
• High level of quality and stability
• Increase of Data Volume– Large distributed archives exploding volume of data
– Increased performance
• Increase of Computation Density– Application growth & diversity
– Blade server technology
• Request of Agility– Organizational responsiveness
– Infrastructure extensibility
EO Networks Drivers (2)
• Heterogeneous environment (User Service, Data Quality, etc)
• Interoperability with National and International partners that challenges the Security
• Stringent timeliness requirements (Near real-time and Emergency Services for crises management)
• Evaluation and Integration of new technology responding to emerging requirements
• More stringent Security Requirements
EO Networks Drivers (3)
In Other words:
More Data
Larger Community (Scientist, GMES, Operational, Industrial and Internal)
Short Delivery Time
Introduction of emerging technology
More efficient and Cost effective
More Secure and Controlled Transactions
An essential commodity service for EO users interactions

Networks for EO (3)
• Artemis ensures almost 30 % contact time per orbit • Very large data volumes are down-linked through Artemis,
corresponding to ~ 50% of all LBR data and ~ 75% of all HBR data (both recorded and real-time)

The use of Satellite DDS for ENVISAT• Satellite dissemination extremely effective for delivery of same
set of data to wide (more than 10) users at the same time.• Eumetsat adopted the same concept to disseminate their data.• Fast deployment of new stations.• Extremely flexible in terms of capacity expansion.• Highly secure (encrypted transmission) and independent from
ground infrastructure.• Possibility to implement a full two-way link.
• Current DDS ensures dissemination in Europe, Africa and America of a prescribed set of products (selected MERIS, AATSR, SCHIAMAKY, MIPAS, GOMOS and ASAR data).

– Study-activity addressing the repatriation of Antarctica data from thenew TrollSat station under different architecture scenario.
– Infrastructure sharing convenience for Capacity below/up-to 20 Mbps.
– One-off cost saving for station upgrade in the Infrastructure sharing model.
– Similar costs between one European Teleport and two Teleports.
– Additional saving may be achieved by having a Teleport in ESRIN
– The introduction of O’Higgins may reduce the overall costs.
The future EO Network (1)• HiSEEN Next Generation
– Possible Optical Network, Dynamic lightpaths, strong Supporting infrastructure
– 10 Gb is available & affordable for today's datacenter
– Asymmetric and flexible model to cover different needs
– Adaptable topology, specially for relevant projects
• Collaboration & Sharing of resources– Exchange/sharing of resources (e.g Capacity) and
Operational processes (e.g. NOC)
• Virtualization (Virtual Archive, Virtual routers, eNOC, etc.)
– Architectural approach for the provision of virtual networks on a shared infrastructure
– Utilization of CDN and Cloud Computing
The future EO Network (2)• Increase of interoperability in multi-domain
environment
• Security– Alignment of the EO PDGS with the new ESA Security
Directives
– Improvement of Confidentiality & Integrity of information
– Introduction of Single-Sign-On infrastructure
– Improve of Operational efficiency (new Esacert)
– Federation (Trusted third party based on ID federation)
• DDS-2G (Second Generation)– Use of newer satellite technologies (e.g. DVB-S2 ACM)
– Exploitation of 2-way system for disadvantaged areas
Conclusions• Network is a critical element of EO infrastructure:
– Unique vehicle to support community specific distributed infrastructure
– Integration of different Earth Science data sources
– Implements the majority of security mechanisms
• The Network provides a common support interface for European and global organizations (essential for EO Global connectivity)
• A combination of Ground and Satellite Networks can support the upcoming EO Missions
• Network move towards a service oriented model (e.g. GN3)
