I will spend some minutes talking about the roll out of ESnet4. We have a reasonably firm schedule now, and this will give a clear picture of the circuits and bandwidths for USLHCNet to US T1 centers, and T1 to T2s and/or T2 peering points.
At the last OPN meeting in Cambridge, we decided that we wold foster the use of perfsonar for OPN monitoring and operations. There was some discussions about how it was a modular framework, and how it would be useful to make sure that all component networks needed to get some traction in deploying common or similar features so that the whole OPN could be monitored.
From DANTE we will present the status of our discussions with C-S for the implementation of the E2ECU and how it afftects LHC. We shall also show how ENOC and E2ECU will interact with one another at runtime. However for the interim phase, I think it is really down to Mathieu to say concretely how intercation with ENOC will work in practice.
I will present shortly what we have drafted to support the OPN in the interim phase. Apart from the issues I already stressed, we have some of the functionalities in place on our side, e.g. the detection of TT that might signal a problem on the OPN and the broadcast of the info to the T1s. I would like to test this before the meeting to give a preview to people.
