Abstract

In this paper we propose a novel extension to the label mapping space in GMPLS networks by exploiting further physical layer properties. The proposed extension, OC-GMPLS, is a modified version of the standard GMPLS. OC-GMPLS relies on adding an optical CDMA code switching layer called Code Switch Capable Layer (CSC) to the existing label mapping layers. OC-GMPLS provides a larger label mapping space and enhances the QoS capabilities for optical networks through increasing the granularity of traffic identification. In our extension we use Manchester signaling to allow for more robust clock recovery while providing enhanced performance over conventional On-Off Keying (OOK) schemes. We also provide a reference architecture for the label switching layers in our OC-GMPLS architecture capable of performing labelling through Optical CDMA. We analyze the performance of the proposed scheme and show that our proposal significantly enhances the overall network performance.
