Bijan Jabbari, will talk about A Scalable Dynamic Path Computation Framework for Inter-Domain IP and Optical Networks. With the growing demand in using traffic engineered label switched paths (LSPs) across multiple domains, the need for dynamic path computation has become unavoidable. The constraint based routing based on CSPF (constrained shortest path first) which determines whether a link meets the traffic engineering constraints within a domain is found to be no longer effective. Path computation Element (PCE) has been introduced to address the present shortcomings and examine more complex set of constraints. This, in particular, has become important when the optical transport attributes are considered in conjunction with the IP links. This talk will review some of the problems with the existing Internet architecture and will provide a framework to augment it with more general and routing and path computation techniques. Our focus will then be on a scalable dynamic fast path computation algorithm. We will present the suitability and effectiveness of this algorithm in dynamically provisioning resources for the end-to-end guaranteed services.
