This paper describes multilayer traffic engineering and signaling technologies in the photonic-GMPLS-router (Hikari-router) network. Multilayer traffic engineering, which yields the dynamic cooperation of IP and photonic layers, is described with the goal of providing IP services cost-effectively. The establishment of photonic cut-through paths is triggered when the Layer 3 traffic loads become excessive which better uses the optical layer (LI) resources. Data on traffic volumes are exchanged among edge photonic router using an extended IBGP. To realize multilayer traffic engineering, we propose an OSPF extension that advertises both the number of total wavelengths and the number of unreserved wavelengths, and an RSVP-TE extension that minimizes the number of wavelength conversions needed. In addition, this paper presents a heuristic-based multilayer topology design scheme in which IP traffic measurements are performed in generalized multiprotocol label switches (GMPLSs). Our design scheme yields the optical label switch path (OLSP) network topology, i.e. OLSP placement that minimizes network cost in the face of fluctuations in IP traffic demand. In other words, the OLSP network topology is dynamically reconfigured to match IP traffic demand. Networks are reconfigured by the proposed scheme so as to utilize the network resources cost-effectively.
