Capability of Optical Code-Based MPLS (OC-MPLS)

We will focus on the novel applications of optical code-base MPLS, so-called OC-MPLS to demonstrate its versatile capability. The OC-photonic label can be used as an identifier of the packet or flow encapsulated in an optical frame. The OC-photonic label is an optical code consisting of a sequence of optical chip pulses, and its recognition is performed based upon ultrafast time-domain optical correlation. The main application is to the label switched path (LSP) switching, but the other applications include IP packet routing as well as flow classification for supporting QoS capabilities. In the optical implementations, two types of match algorithms of OC-photonic labels such as exact match for the LSP and flow classification as well as longest prefix match for II’ packet routing are presented. Finally, the exact match, longest prefix match, and classification of optical packet flows will be experimentally demonstrated at the bit rate of 10Gb/s.
