What is JANET?

•JANET is a National Research and Education Network (NREN)

•There are many others

•See WWW.TERENA.NL for other European ones and helpful links


NRENs

Technologies

•Backbone – Optical Fibre

•MANS – Fibre, co-ax, Microwave

•Local – Copper, co-ax, wireless, satellite


•Moving images

•Remote teaching and learning (e-University?)

•Endogenous growth

•E-science (The GRID, and other things)

•E-business

Influences on traffic growth


•Growth in self-provided services•Multimedia/Library digitisation•Net competent students•The geography of the learning

experience•Mobile communications

Influences - continued


Influences - continued

•Improved local and regional infrastructure

•Digital television

•Lifelong Learning

•Commercial relationships (ASP services)


•Authentication/Security/Integrity

•Customer Support

•Reliability

•Traffic planning and management

•Pervasive access

Technical Challenges


Bigger Challenges - 1

•Changing Customer Base

•Inclusive systems of governance

•Top Slice vs. charging

•Do we still need a private network?

•The role of the MAN


Bigger Challenges - 2

•Flexibility to enable further educational connections

•The telecommunications market


Conclusion

1. Increasing applications and reducing prices lead to greater network use

2. Societal changes reinforce this tendency

3. “Quantitative change leads to qualitative change”


Conclusion - continued

4. Qualitative change shows up in the growth of the user community

5. It is affecting arrangements for funding, network management and customer support

6. Service quality remains high despite the tumult in the market
