3/17/03 Status Proposal for graduate student support submitted to EPSCoR Proposal for MEMS switch and EDFA submitted to PTAP Surplus optical test equipment acquired from Telcordia Graduate student (Saritha Acher) beginning to work with equipment Exploring additional NSF program opportunities for optical technology applications

3/17/03 Optical networks for demanding applications – beyond Internet2 Several applications at MSU that demand hiigh bandwidth connectivity, low latency, remote computation, realtime visualization: –CCB: Neuroscience application requiring distributed processing, remote real-time visualization and real- time access to multiple, distributed data sets –Solar Physics: Satellite operations, Virtual Solar Observatory –Ag Science: Multi-state program involving remote sensing data, visualization –Maybe others?

3/17/03 The opportunity: respond to NSF Experimental Infrastructure Network (EIN) Program EIN goals: Explore next generation networks to meet e-science application needs not met by today’s networks NSF looking for application-driven innovation in networks and software Encouraging multi-campus, regional collaborations; Use of pre-market emerging technologies; industry participation

3/17/03 EIN Proposal CS, ECE lead the effort, develop common software and network infrastructure to support multiple applications Partnerships: –Remote sites with application-specific data, computational capabilities, models –Become client of advanced grid computing: OptiPuter project (UCSD) –Join National Light Rail: high speed fiber backbone –Industrial partners: Calient Systems: MEMS-based optical switch Telcordia Technologies: transparent optical network management software

3/17/03 Educational initiatives ECE focus on telecommunications – some curriculum adjustments Gilhousen Telecommunications Colloquium series Gilhousen undergraduate student scholarships Graduate student recruitment

3/17/03 ECE focus on telecommunications – some curriculum adjustments Continue ECE 400 level telecom courses annually (EE 445, EE 446, EE 447) with some adjustments to EE 447 Offer EE 543 (telecom switching and transmission) each fall Add a graduate level course, “advanced topics in telecom systems”, offer annually and allow repeated enrollment Encourage EE/telecom majors to take CS 440,”computer networks” Add a CS or EE course in advanced network architectures and protocols

3/17/03 Gilhousen Telecommunications Colloquium series Broad range of topics, loosely related to telecommunications issues Bring in external speakers, supplement with talks by faculty and grad students Mondays, 2:10 PM 101 Roberts Hall Computer Scientists are WELCOME!!
