DOE NGI Application Information

The following chart gives some characteristics of the XPorts projects requirements on the network end.  It particurlarly focuses on the needs from ESNet, the Energy Sciences Network.
 
 

Project Name	Grid-based X-Ray Crystalography Collaboratory
Application Description	instrument data stream analysis, remote storage, and feedback control
PI's	Randall Bramley (bramley@cs.indiana.edu)  Donald F. (Rick) McMullen (mcmullen@indiana.edu)
Sites Involved	site ISP/Network application/system component IU Abilene processing and storage (HPSS) LBNL ESNet data source (ALS) ANL ESNet data source (APS), processing and storage
Networks Used	ESnet, Abilene
Bandwidth Requirements	bulk transfer of individual CCD frames (9-32MB) from LBNL to IU in <2sec:  ~128Mbps sustained for ~12 h. per experiment 2 or more channels of streaming video: 384Kbps ea. visualization and IPC requirements for distributed reduction and analysis programs being evaluated
Latency Requirements	Max allowable latency will vary from 0.1 seconds for interactive collaboration and initial structure determination, to several seconds for later stages of a given x-ray session.
QOS Requirments (bandwidth, jitter, etc.)	128Mbit/sec bandwidth reservation
Other (multicast? multiple streams? etc)	parallel data transfer streams using pftp to HPSS, PtP and multicast video teleconferencing
Systems used  and their locations (e.g.: HPSS, T3E, PC cluster, Cave, etc.)	site systems used IU SP, HPSS, SGI O2K, CAVE, IDesk LBNL ALS (instrument) ANL SP, APS (instrument)
