  7. ASF CNES/ESA NOAA JAXA Asia Region GA Europe and Africa Region North and South America Region Australia and Oceania Region Antarctica : JAXA in association with National Institute of Polar Research Data exchange scheme for each Mission- Future Mission (1/2) - ALOS Data Node framework to enhance to use the data more efficiently. • 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 • JAXA will receive global ALOS (to be launch in 2005) data via Data Relay satellite. • JAXA to send 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 • 20Mbps/Node.

  8. Data exchange scheme for each Mission- Future Mission (2/2) - High Latitude data receiving station and network transfer to Japan. ALOS (backup usage) GOSAT (nominal usage) SSC @ Sweden, Kiruna Or KSAT @ Norway, Toromso/Svalvard • High Latitude receiving station capture the GOSAT (and ALOS) data each 100min interval. • Data Volume is 44GB/day for GOSAT and same level or more for ALOS. • Receiving the data in 100min/orbit -> necessary STABLE/RELIABLE bandwidth over 20Mbps.

  9. 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 is planning to transit from leased line to APANorSInet. • In terms of future mission (ALOS, GOSAT,...), data volume is huge and we need STABLE, RELIABLE and REASONABLE network. • This Japanese Fiscal Year, JAXA is planning to evaluate the network performance, transfer protocol and security by using APAN before future mission become operational.

  11. Experiment detailSys. Configuration (2/3) Protocol Layer Configuration Northern Europe JAXA/JAPAN APAN + Abilene + GEANT AP AP FTP FTP TCP XTP TCP IPv4 (IPv6 into the future) • XTP (Xpress Transfer Protocol) : • Eliminates the impact of high latency due to distance delay, and accelerates all TCP based applications (especially large flow, e.g. large file transfer via intercontinental links). • Eliminates high packet loss and unnecessary retransmissions. • Establish communication pass immediately. (XTP:1 packet, TCP:3packets) • Supports multicast.

  13. Experiment detailTest Overview • Before we begin: • Verify by ping command that a healthy network exists end-to-end. • The Test: • Transport mission data files (MAX size:1GB) via several FTP/TCP and FTP/XTP links. • Monitor the throughput of FTP/TCP and FTP/XTP traffic. • Verify that APAN network and XTP supplies efficient mission data transmission.
