Data shipment in the Ground Segment


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


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

Centres

• Frascati (IT): ERS, Envisat• Kiruna Salmijarvi (SE): ERS, Envisat, Cryosat• Kiruna ESRANGE (SE): Landsat MMS, ALOS• Farnborough (UK): ERS, Envisat• Oberpfaffenhofen DLR (DE): ERS, Envisat, MODIS, DLR

missions• Matera (IT): ERS, Envisat, Landsat TM/ETM• Maspalomas (ES): Envisat, ERS, SeaWiFs, NOAA• CNES, Toulouse (FR): Envisat, CNES missions, Cryosat• Svalbard (NO): Envisat, ADM• Tromsoe (NO): ERS-2 ATSR, TPM• Neustrelitz (DE): TPM, ALOS

• Gatineau (Canada) ERS-2, ADM• Prince Albert (Canada) ERS-2, ADM• (Finland) Envisat


Initial requirements

• Electronic data shipment between Centers– 34 Mbps incoming or outgoing nominally 60% occupied– ~200 GByte per day– MTTR maximum 1 day

• Internet Data distribution to users– > 34 Mbps outgoing per Centre– High availability and guaranteed QoS for NRT users

• Bandwidth requirements evolution (next 10 years)– X10 for EO constellations for Global Environmental

Monitoring (GMES) – X50 for high resolution satellites

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


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 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 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


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


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


Connectivity Requirements

•Connectivity with commercial providers for Data Access

•Connectivity with US, Canada and Japan and southern hemisphere for Data exchange amongst Centers


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
