Traffic-driven virtual network topology reconfiguration for GMPLS network

This paper proposes a statistical traffic processing scheme that makes virtual network topology (VNT) reconfiguration depend on average traffic value for the generalized multi-protocol label switching (GMPLS) network. This scheme dynamically changes the smoothing traffic value depending on the burst characteristics of the traffic. Feasibility of this scheme is confirmed by implementing it in GMPLS routers and confirming that the system works properly in a distributed-control network
