---+ gLite File Transfer Service FTS knowledge base

---++ CSCS specific information

The current FTS model foresees dedicated channels for T1->T2 channels, and so called STAR->T2 channels which take the rest of the transfers. It makes sense that a Tier-2 can exercise control over its own inbound channels.

Our primary channels are hosted by our Tier-1 at FZK:
   * FZK-CSCS
   * STAR-CSCS

The FZK FTS endpoint is =https://fts2-fzk.gridka.de:8443/glite-data-transfer-fts/services/${servicename}=. 

Endpoints for all centers can be found through the BDII. E.g. you can use the following command for finding all endpoints for CMS:
<pre>
lcg-infosites --vo cms fts
</pre>

Using this information one can run queries like this:
<pre>
FTSEP=glite-transfer-channel-list -s https://fts2-fzk.gridka.de:8443/glite-data-transfer-fts/services
$> glite-transfer-channel-list -s $FTSEP/ChannelManagement FZK-CSCS
Channel: FZK-CSCS
Between: FZK-LCG2 and CSCS-LCG2
State: Inactive
Contact: (null)
Bandwidth: 0
Nominal throughput: 0
Number of files: 10, streams: 1
Number of VO shares: 4
VO 'cms' share is: 40
VO 'ops' share is: 10
VO 'dteam' share is: 10
VO 'atlas' share is: 40


$> glite-transfer-channel-set -s $FTSEP/ChannelManagement -S Inactive STAR-CSCS

---++ Things to know

The documentation is quite unorganized as of May29 2006. It is important to note
that all of the (good) documentation is in the man pages of the =glite-transfer-= executables.
So the best way of getting to know how to use the FTS is to list all glite-transfer commands
and reading through their man pages.

A very important tool to know is called =glite-transfer-discovery= which will look in the
information system trying to find the FTS endpoint that needs to be contacted to run the
given transfer.
