Evaluation of path computation engines in multi domain scenarios: extended abstract

The goal of the UPIN [1] project is providing knowledge and control to end users of a multi-domain network like the Internet to increase security of data in transit. The process of setting up a path across multiple domains according to end-to-end constraints set by the user necessitates a heavy exchange of control messages between the domains involved. In this paper, we investigate how Path Computation Engines (PCEs) that control single domains can help also in the setup of a multi-domain path. This research addresses the lack of transparency, accountability and controllability in today's Internet and narrows the gap towards a Responsible Internet.
