Some server-client tests done: UDP tests

Conclusions after TIM at Houston:

1. Save outstandings presentations from the colleagues. Professor Ting's presentation about the AMS02 research project. Download video of the ISS integration showed by Trend Martin and posted on the NASA web page. Half presentation missed about the safety issue. Alexei, Mike and Xei presentation about the GSE (few mentions to the Computing System).
2. Remember the connection link will have an average of 2 Mbps. But the connection will be able to receive peaks up to 50 Mbps, so be prepared to receive correctly up to 50 but be aware of the storage system will be limited to 2 Mbps it means around 21.6 GB per day.
3. Still missing diferences between flight operation, STA state, testing state-> nomenclature.

Steps to follow:

1. Send email to Marco Incagli from the Perugian University requesting for AMS data. They are working in the ECAL project so the have been already testing it and obtaining raw data of the cosmic rays. He commented the existance of around 1 GB of raw data already packed in the format designed for the AMS blocks.
2. Still not pretty sure of the UDP blocks configuration, I assumed firstly would be CCSDS. But the guys work on AMS02blocks directly and it seems that CCSDS can be any data from any ISS payloads. And it will be given only the correct data to us, so it should be given AMS02blocks. IT WILL NEED SOME MODIFICATION OF THE RECEIVING SCRIPT.
3. Not yet confirmed about NASA firewalls, now design the system, and speak with Alexei how to do. Can be done as one of the latest thing of the project. Contatct for it Tim Urban, Engineer of NASA.
4. It is clear that is need only for one machine, which works as a receiving and server for downloading the data.
5. System of download will be basic and simple. Running commands as sftp or scp, Alexei is not interested in graphic interfaces or complex systems as Tsunami.

Status

1. ECAL data received 16/01/2007
