Abstract: This article describes the first multi-area Multi-Protocol Label Switching (MPLS) and Generalized MPLS interoperability trial over Reconfigurable Optical Add/Drop Multiplexer (ROADM) and Optical Cross-Connect (OXC) network. The interoperability trial demonstrated the routing of Label Switched Paths (LSPs) over a multi-area GMPLS controlled ROADM/OXC network and the control of Ethernet over MPLS (EoMPLS) transport service on top of the GMPLS network. The trial was conducted using various network elements provided by 14 institutions and was carried out at Tokyo and Virginia. This article introduces the motivation of the trial, technical issues related to controlling multi-area MPLS/GMPLS networks, test network topology, and experimental results. The results show that the interior gateway routing protocol based multi-area routing architecture is a promising solution for the nationwide deployment of GMPLS networks within a carrier domain. Furthermore, this article discusses the technical issues of routing constraints in ROADM/OXC networks and the limit of multi-area routing without Path Computation Element Protocol (PCEP).
