Feedback

Initial Learning -- Penn State

– Initial rollout spring ’04 to residence hall students; rolls to 80K students in Fall ’04

– Tremendous demand: 10,000 students joined in 6 weeks!

– Persistent, heavy usage indicates a change in behavior away from p2p

– Frequency of RIAA compliance letters has dropped dramatically

– 90% of all downloads delivered within the network – tremendous bandwidth savings


Usage and Performance

Sustained, heavy usage80-100K downloads/streams per day

Cache hit rate > 90%


Lessons Learned

positive student response validates service model

– in discussion with over 100 schools

– enhancements and local content under discussion

caching is even more critical then we thought

– every school has expressed interest

– we are working with IBM to scale the program

collaboration with University on all aspects of rollout is critical to success

– from student government to the IT departments
