Data exchange scheme for each Mission- Future Mission (1/2) -

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

ALOS Data Node framework to enhance to use the data more efficiently.

•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.

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, KirunaOrKSAT @ 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.

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.

Experiment detailSys. Configuration (2/3)

Protocol Layer Configuration

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.

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.
