2. CA*net 4 Update • CA*net 3 terminates July 31, 2002 • CA*net 4 RFI issued August 2001 • CA*net 4 funding announced Dec 2001 - $110m • One time grant for 5 years • Selection of carrier(s) to be announced shortly • Initial OC192 network on all path with plans to upgrade over the next couple of years • Selection of equipment supplier(s) to be announced shortly • But dramatic reduction in number and size of routers • CA*net 4 scheduled to be turned up July 1st, 2002

4. The CA*net 4 Objective-1 Canada’s National Innovation Infrastructure • Primary mission of CA*net 4 will be to support basic research and education amongst higher ed institutions, research centers,schools, etc • CA*net will be foundation of “innovation infrastructure” by interconnecting regional networks, universities, schools, to promote an “innovation culture” through advanced applications such as tele-learning, eScience, grids, etc • Examples: • National Bio-informatics grid linking bio-informatics research institutes across the country • Cosmic Ray eScience grid interconnecting UoAlberta and schools across the country

5. The CA*net 4 Objective –2 • There is a growing trend for many schools, universities and businesses to control and manage their own dark fiber • Can we extend this concept so that they can also own and manage their own wavelengths? • Customer empowered optical networks are built on the paradigm that customer owns and controls the wavelengths (Virtual Dark Fiber) • Customer controls the setup, tear down and routing of the wavelength between itself and other customers • Wavelength resource management is done on on peer to peer basis rather than by central administrative organization • Network is now an asset, rather than a service • Will “empowering” customers to control and manage their own networks result in new applications and services similar to how the PC empowered users to develop new computing applications?

6. The CA*net 4 Objective-3 Customer Empowered Networking • To partner with industry in development of new protocols and technologies required so that customers at the edge of the network own and control their own wavelengths • Extension of the classic end-2-end Internet principle which has been shown to significantly enhance innovation • CANARIE optical cross connect switches are like mini IXs • CANARIE will physically maintain optical cross connect switches but customer who owns wavelength controls the associated cross connect remotely • Customer can re-route or re-terminate wavelength any time they so chose • Object Oriented Networking – OON • Light paths and cross connects are an “object” with attributes and method including inheritance, polymorphism, classes, etc

9. Mini-IXs are the core of CA*net 4 • Ideal for large data flows used in Grid applications • Networks of mini-IXs can be linked together for specific application communities and allow direct peering between institutions and researchers • E.g. High energy physics network of mini-IXs • Regional networks and universities can connect to mini-IXs to off load P2P traffic • Or network of mini-IXs for residences and student dormitories to off load P2P traffic • The beauty of mini-IX is that architecture is recursive like other successful Internet protocols e.g. HTTP, DNS, etc • Most optical protocols are reiterative and subject to scaling issues e.g. GMPLS

11. Object Oriented Networking • Combines concepts of Active Networks, Internet 2 e2e principles and Grids • Customer owns sets of wavelengths and cross connects on an optical switch • Similar in concept to nested VPNs with customer control of Add/Drop • Network elements or nested VPNs can be treated as a set of objects in software applications or grids • Complete with inheritances and classes, etc • In future researchers will purchase networks just like super computers, telescopes or other big science equipment • Networks will be an asset – not a service • Will be able to trade swap and sell wavelengths and optical cross connects on commodity markets
