Welcome to Element. This site is dedicated to tracking the technical developments of path computation and traffic engineering technologies.

The capability to compute optimised end-to-end paths across a variety of network layers, domains, or inter-domains, is an essential requirement in today’s transport and service network. A variety of technologies exist to aid in this process. For instance, a Path Computation Element (PCE), defined by the Internet Engineering Task Force (IETF) is capable of computing a network path or route based on a network graph and applying computational constraints.

I will continue to track the various developments and applications of PCE and Traffic Engineering (TE) technologies using this site. The site also has a number of technology Frequently Ask Questions (FAQs), directly and indirectly related to the technology being discussed on this site. I have also highlighted a number of useful presentations, journals and white papers. Finally, I use the site to track my own efforts regrading the standardisation and application of various PCE and TE technologies. If you have any comments or suggestions regarding the site I am always glad to hear them. You can contact me via the "Contact Me" link in the main menu.
