With the Internet Protocol (IP) being the dominant protocol for new optical network services, there is increasing pressure to optimize the network infrastructure and protocols for IP traffic. This paper presents a technology for constructing a novel architecture for IP over photonic systems. WDM network has been launched by the concept of wavelength routing. The principle is that high-speed data flows, which consist of many time-division multiplexed channels, are associated with specific optical wavelengths. Thus, they are routed through the optical network by means of their wavelengths. Thus, wavelength routing consents the realization of OXCs working in an efficient way. However, MPLS-based forwarding is still an electronic solution. Therefore, even though MPLS needs to establish a closed domain to utilize a new lower-layer technology, it is still useful to incorporate optical technology herein to further increase throughputs for large-scale Internet networks. Moreover, provisioning wavelength capabilities based on MPLS has emerged, that is , multi-protocol lambda switching (MPλS). This system tries to merge the functionalities of the wavelength switching, SONET mux/demux, and IP routing into one layer, and is sometimes known as the concept of optical MPLS and MPLambdaS. Its extension Generalized-MPLS(GMPLS) is also discussed.
