Abstract: Provided herein is a path computation element based on Transport Network Assigned (TNA) address and a method for path computation based on User Network Interface (UNI). The path computation element and UNI based path computation method of the present disclosure minimize overhead caused by abstract Traffic Engineering (TE) link, and minimize manual environment set up, and routing information exchange and advertisements in a local domain or between domains.

Abstract: Provided is a hybrid passive optical network (PON) system. The hybrid PON system of wavelength division multiplexing (WDM)/time division multiplexing (TDM) may include an optical line terminal (OLT) and an optical network unit (ONU). The OLT and the ONU may transmit a signal based on wavelength reuse using a seed light source and a reflective modulator. The light source may include a seed light source having a single wavelength, two seed light sources having different wavelength bands, and a light source having a wavelength tunable characteristic.
