Implementation of multi-layer techniques using FEDERICA, PASITO and OneLab network infrastructures

摘要

This paper describes an implementation of multi-layer techniques using the network infrastructure provided by FEDERICA, PASITO and OneLab projects. FEDERICA project provides a network infrastructure, based on virtualization capabilities in both network and computing resources, which creates custom-made virtual environments. PASITO is a layer-2 network that connects universities and research centers in Spain. OneLab measurements tools allow carrying out high-accuracy active network measurements. Thanks to FEDERICA and PASITO, we have a multi-layer architecture where the traffic is routed based on the measurements of OneLab equipment. To carry out this experiment, we have developed a Multi-layer Traffic Engineering manager and an implementation of the Path Computation Element Protocol to solve the lack of a control plane in IP oriented networks. This work shows the feasibility of multi-layer techniques as a convenient solution for network operators and it validates our Path Computation Element implementation.
