This paper describes multi-layer traffic engineering and signaling technologies in photonic-GMPLS-router network. Multi-layer traffic engineering, which yields the dynamic cooperation of IP and photonic layers, is described to provide IP services cost-effectively. To realize multilayer traffic engineering, we propose the OSPF extension, which advertises both the number of total wavelengths and the number of unreserved wavelengths, and the RSVP-TE extension, which realizes least number of wavelength conversion. in addition, this paper presents a heuristic-based multi-layer topology design scheme that uses IP traffic measurements in a generalized multi-protocol label switch (GMPLS). Our design scheme yields the optical label switch path (OLSP) network topology, i.e. OLSP placement, that minimizes network cost, in response to 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.
