Building the next generation Internet architecture in Canada
Bill St. Arnaud
Around the world there are several initiatives to develop the next generation canonical Internet network architecture. These initiatives are being driven by at least four significant developments, first: the concern that the current Internet is ossifying and that it is increasingly difficult to deploy new architectures, secondly: the trend towards a two tiered Internet where the owners of the network control access by third partners, thirdly: the trend for more users to own, control and manage their own network resources and fourthly: the demand by big science and large enterprises to have dedicated network resources for the data flows generated by their high-end applications. One approach to address all these issues is being developed in Canada by CANARIE where a key assumption is that there is no longer need for a canonical network architecture.
Instead, the User Controlled LightPath (UCLP) software developed by CANARIE and its partners allows users to define their own packet or switched based network architecture including topology, routing, virtual routers, switches, virtual machines and protocols based on the concept of many separate, concurrent and independently managed Articulated Private Networks (APN) operating on top of one or more network substrates across different ownership domains. APNs can be considered as a next generation Virtual Private Network where a user can create a complex network multi-domain topology by binding together layer 1 through 3 network links, computers, time slices and virtual or real routing and/or switching nodes. This capability of UCLP is realized by representing all such network element, devices and links as web services, and by using web services workflow as the tool to allow the user to bind together their various web services to create a long lived APN instantiation. With web services workflow the user also has the ability to offer all, or portions of their APN as a web service (or set of services) in its own right to other downstream users.
