10 years ago<br />Three major issues:<br />Very hierarchical IP networks<br />Limited ability to innovate or support high end users<br />Supporting high science users on campus<br />Firewalls, misconfigs, limited bandwidth <br />Heterogeneous independent customer owned fiber networks<br />But how do you build end to end solutions from independent federated networks?<br />
Regional<br />Today’s (2001) hierarchical IP network<br />Other national networks<br />National or Pan-Nationl IP Network<br />NREN A<br />NREN C<br />NREN B<br />NREN D<br />University<br />
Thanks to GLIF and LHCONE<br />Our vision for optical lightpath exchanges (GOLEs) is now becoming a reality<br />LHCONE will drive this new network reality<br />Hierarchical IP R&E networks will not disappear – but will be complemented by direct optical connections through GLIF and GOLEs especially for eScience<br />

Share infrastructure & maximize lower cost power by “following wind & sun” networks.

What are the major future challenges and opportunities?<br />Universities are under increasing financial pressure <br />Need to reduce costs across the board including fees to eScience infrastructure<br />IT energy consumption 20-40%<br />Increasing demand for more eScience research and applications<br />Increasing demand for nation wide mobile seamless services especially for personal health applications <br />Very little disaster planning, especially from climate change<br />
My predictions -1<br />R&E networks will need to partner with industry and campus IT to develop solutions for eScience and general IP to reduce staff workload and energy costs<br />Campus IT don’t have technical resources or budget to deal with DNSESC, IPv6, eScience<br />Ottawa University recently contract with Bell Canada for management of their 3500 Hotspots<br />Federated optical network linking GOLEs will be dominant network architecture (perhaps based on OpenFLOW<br />
My predictions -2<br />Climate change is a real and present threat<br />We are on the cusp of major climatic disruption<br />ICT has become the heavy industry of the information age<br />CO2 emissions from ICT exceed smelters, steel mills and cement plants<br />Continuing dramatic growth rate<br />Energy efficiency is not enough<br />We don’t have enough time to reduce emissions through energy efficiency<br />We have seen from Dallas Thorton’s presentation we can achieve 75% reduction in energy costs and 100% reduction in CO2 emissions by relocating data centers to colder climates<br />This represents tens if not hundreds of millions of dollars in annual savings<br />Energy efficiency will never achieve this<br />ICT represents 20-40% of electrical energy consumption at a university<br />We need to find solutions so that money spent on energy consumption can be redirected to support research and education<br />
