Paper Abstract

In the traditional multi-granularity switching system, the wavelength is the smallest exchange granularity, but the wavelength granularity is coarse, which is not suitable for small-scale integrated services.Therefore, the optical code packet granularity is introduced, and a three-layer multi-granularity optical cross-connect (MG-OXC) system is established based on optical code division multiplexing (OCDM).Subsequently, the Code Group Routing Entity (CGRE) technology was proposed, which not only improves the utilization of wavelengths, but also reduces the number of ports required for service transmission and reduces network operation costs.In this paper, based on the premise of CGRE technology, a code group routing table is established according to the PCEP general standard and a new code group routing allocation strategy is proposed.The new code group routing allocation strategy can make full use of optical code resources in the wavelength, improve network performance, and reduce network operation costs.
