Hi Jens,
Where did the network description go? We used to have one.
The idea is that certain protocols can be used only locally, or on certain networks.
For example, a single StorageElement can have a range of GridFTP data movers on the WAN, a LAN protocol internally, and an OPN link which accepts UDP-based high speed data transfer like the astronomers use.
If you are a local job you can ask it "do you support gridftp" and it would say yes, but you cannot necessarily access the GridFTP data movers from the worker nodes - and it would be less efficient than the LAN protocol.
I think we need to put it back, and StorageAccessProtocol seems to me the more obvious location.
We discussed it a few meetings ago and felt that it overly complicated the schema for the amount of gain in the short/medium term. For example, insecure RFIO and DCAP are published without restrictions, and in practice this is not a real problem today. Since we want to converge on 2.0 ASAP, we felt such enhancements were better considered for 2.1. Would that be OK for you? Thanks, Maarten
