Abstract

This paper reports a realization of a traffic engineering (TE) strategy based on a distributed control plane (Internet-like), and a performance analysis based on experiments carried out on the realized test bed and on simulations. The implementation of control plane is based on standard IP protocols, namely OSPF-TE for routing and RSVP-TE for signaling, which have been suitably extended to support the reported TE strategy. Furthermore, a threshold mechanism for limiting the information flood in the network is reported. The performance analysis assesses the validity of the proposed strategy, by reporting simulation results and measurements achieved on the test bed. In particular, the paper shows that the non-ideality due to real signaling flow and related databases updating are reasonable and in-line with real systems.
