Using distributed databases at Caltech, CERN, possibly UCSD and other HEP institutes, we will show
The client hardware on the show floor will consist of a head node for display purposes (running the ROOT and MonaLisa applications), twelve latest generation dual processor servers each equipped with a SysKonnect SK9843 Gbit fibre interface. These servers will run the Linux OS with TCP mods. Remotely, at Starlight, Caltech, CERN, Florida and probably at least one other HEP institute, we will make use of Linux and Windows-based servers that host Oracle, SQLServer and probably PostgreSQL database, and which run the Caltech "Clarens" server software that communicates with the ROOT client. Networking will be using various routes. An overview is shown in the Starlight network diagram below.
Work on preparing this demonstration is within the context of our recently submitted proposal to NSF to develop TCP/AQM, which was accompanied by letters of support from Internet2, several other research organisations and vendors. We expect this project to consequently have considerable visibility in the networking community (as well as in HEP).
Here is a diagram of the Clarens architecture used on the servers:
