2007/1/23 APAN JAXA/EORC/Fuda 4 Data exchange scheme for each Mission - Daichi (ALOS) - Each Node is associated with a geographical zone which defines the extent of its area of activity (supporting the physical residents therein as potential ALOS users) as an ADN partner. - ESA: Europe and Africa - NOAA/ASF: North and South America - GA: Oceania - JAXA: Asia - GISTDA: Asian Sub-Node ESA NOAA ASF JAXA GA Asia Region Europe and Africa Region Australia and Oceania Region North and South America Region Antarctica : JAXA in association with National Institute of Polar Research ALOS Data Node framework to enhance to use the data more efficiently. JAXA is now receiving global Daichi (ALOS) data via Data Relay satellite (Kodama). JAXA is sending the ALOS Level 0 data to each Node (Currently media (SONY/DTF-2) shipment.) JAXA and Nodes are discussing to move the High Speed network transfer. Data Volume totally 600GB/day (ESA: 146GB/day, ASF: 180GB/day, GA: 58GB/day, GISTDA: 61GB/day, other: 91GB/day). Each Node to receive the data in 24hours -> necessary STABLE/RELIABLE bandwidth 25Mbps/Node. GISTDA

2007/1/23 APAN JAXA/EORC/Fuda 6 Data exchange scheme for each Mission - GOSAT (near future) - High Latitude data receiving station and network transfer to Japan. GOSAT Tromso/Svalbard High Latitude receiving station capture the GOSAT data each 100min interval. Data Volume is up to 60GB/day for GOSAT. Receiving the data in 100min/orbit -> necessary STABLE/RELIABLE bandwidth over 20Mbps.

2007/1/23 APAN JAXA/EORC/Fuda 7 Purpose of the experiment Based on the JAXA EO satellite plan, data exchange volume will increase. Data exchange and distribution are also encouraged as near real time base. In terms of current mission (TRMM, AMSR-E), JAXA utilizes APAN. In terms of Daichi (ALOS) and future mission (GOSAT,...), data volume is huge and we need STABLE, RELIABLE and REASONABLE network. Next month, JAXA is planning to evaluate the network performance, stability, transfer protocol and security by using APAN.

2007/1/23 APAN JAXA/EORC/Fuda 8 Experiment detail Test Overview Before we begin:  Verify by ping command that a healthy network exists end-to- end.  Confirm the network route by traceroute. The Test:  Transport real Daichi (ALOS) mission data files (MAX size: 1GB) via several FTP/TCP and SCP/UDP links.  Monitor the throughput both of FTP/TCP and SCP/UDP traffic.  Check the stability both of FTP and SCP during 24H.  Verify that APAN network and UDP supplies efficient mission data transmission.
