We developed distributed-controlled multi-layer traffic engineering system. There is no previous works that report the system. Therefore, we can not confirm feasibility and scalability of the system. In this paper, we report an experiment on our system consisting of Internet protocol (IP) routers and optical cross-connects (OXCs). In this system, control is provided by generalized multi-protocol label switching (GMPLS) and IP network topology and IP routes are dynamically reconfigured to suit traffic characteristics. These functions prevent traffic congestion as well as any decrease in link utilization rates. We had experiments to test behavior of the routers and OXCs depending on traffic characteristics. We cleared that the distributed-controlled multi-protocol label switching (MPLS)/GMPLS traffic engineering system was feasible and scalable by the experiments.
