How No Collisions Makes Better Physics: All you ever wanted to know about achieving your Wide-Area-Networking Goals. Internet connectivity is critical infrastructure for modern HEP experiments, computing goals can only be achieved with reliable, fast connections between geographically separate regions. In this talk we will discuss past and future performance, how the requirements of HEP can be met and how we will know. We will examine several networks and review several monitoring projects. We aim to detect the recipe for success.Les also put together a rough outline:
Active End-to-end Internet Performance Measurements in HEP & Elsewhere:
when no collisions makes better physics
Why we care
Distance independent collaborations
Methodology, deployment
Validation
thruput, http
Comparison with other Active IEPM projects
Results
Long term thruput trends
Comparisons between networks
Importance of routing
Monitoring of major HEP collaborations
We agreed to think about this in more detail and return to it at the next meeting (see below).
Bill made the following suggestions:
HEPNRC have the SAS database on a Unix platform, and have a devlopment license for NT. the development license includes support for Java. However, the development package has to run on the same platform as the database. Porting the data from Unix to NT is a big effort according to Shiqui. Warren needs to be able to access the SAS data base at HEPNRC froma remote client at say SLAC. Warren & his student Yvonne are working on a Java interface (using JDBC) to Oracle and a public domain SQL database. It would be good if one could plug SAS into this. To do this requires a SAS driver. SAS does have support for ODBC. Warren and Shiqui will follow up with SAS.
