Architectures lab for scalability and interdomain traffic engineering on the Internet: LISP and PCE integration (LITE)

Researchers: Xavi Masip, Marcelo Yannuzzi, René Serral

Duration of the Project: from September 2008 to August 2009

One of the proposals to tackle the problems derived from the current addressing scheme is the separation of the location and identification functions inherent in IP addresses. The initiative that is more advanced in terms of specification is LISP (Locator/ID Separation protocol). In LISP, a mapping system is required between the locators and the identifiers. There are currently some proposals for a mapping system for LISP, but none of the solutions under discussion specifies how to apply constraint-based routing techniques to actively engineer interdomain traffic through the mappings. This is especially important for Latin American networks, since these are reachable through heterogenous and typically loaded links, with different characteristics in terms of delays, packet losses, etc. This project aims to extend the implementation of LISP and add constraint-based routing control over the mapping system, with special focus on a convergent PCE/LISP control plane. To this end, the project proposes to start from a running (and tested) implementation of the PCE already developed by the research team. The project will test the extension to LISP using the research infraestructure RedCLARA, as the transport network between two testbeds, one in Spain and the other one in Uruguay.
