Versatile optical-code-based MPLS for circuit-, burst-, and packet switchings

Versatile OC-based MPLS for circuit-, burst-, and packet switchings is presented. The OC-label is an identifier attached to the data, of which information is mapped onto an optical code, a sequence of optical pulses. The OC-label recognition is performed by the optical correlation between an incoming OC-label and the OC-label entries. Unique to the OC-label processing is that it is analogue operation entirely in optical domain, and no optical logic operation is involved, therefore, the processing speed is only limited by the propagation delay in the optical correlator, which is a passive optical device. This is a key to the ultrahigh-speed processing capability. The OC-label switching technology will create a new paradigm for the next generation photonic networkings.
