| Abstract: | Wavelength division multiplexing technique combined with time division multiplexing form mixed WDM EPON.How to improve the system bandwith utilization and quality of service has become the key technology.Combined with the existing algorithms,this paper proposes a new dynamic wavelength and bandwidth allocation algorithm which allocates the bandwith and wavelength to the ONU based on different traffic types and SLA weights.The purpose of doing it is to improve the quality of service,utilization rate of the uplink bandwidth and fairness of bandwidth allocation.,and finally improve the performance of the network. |
