Interoperability among products was successfully demonstrated by four vendors： Broadcom, PMC-Sierra Opulan and ZTE. Each vendor supplied an OLT and a variety of ONUs （supporting both 1G-EPON and symmetric 10G-EPON）, connected in a multi-vendor展开更多
GPON与EPON是两种不同的PON技术.在两种技术的演进过程中,业界对这两种技术特点和应用一直有着不同的认识.尤其是近些年来一些通信网运营商的一系列重要发展决定,给业界认识上带来了很大争论.通过对两种技术及其演进技术的比较,同时重点...GPON与EPON是两种不同的PON技术.在两种技术的演进过程中,业界对这两种技术特点和应用一直有着不同的认识.尤其是近些年来一些通信网运营商的一系列重要发展决定,给业界认识上带来了很大争论.通过对两种技术及其演进技术的比较,同时重点对EPON的演进技术10 G EPON进行了分析,得出10 G EPON与10 G GPON技术共存是接入网近几年内主要应用模式.最后预测今后接入网的主导技术是×G EPON.展开更多

Aimed at enhancing the quality of service( Qo S) brought by diversified-services,this study proposes an echo state network( ESN)based multi-service awareness mechanism in 10-Gigabite ethernet passive optical network( 10GEPON). In the proposed approach,distributed architecture is adopted to realize this ESN based multi-service awareness. According to the network architecture of 10G-EPON,where a main ESN is running in OLT and a number of ESN agents works in ONUs. The main-ESN plays the main function of service-awareness from the total view of various kinds of services in 10G-EPON system,by full ESN training. Then,the reservoir information of well-trained ESN in OLT will be broadcasted to all ONUs and those ESN agents working in ONUs are allowed to conduct independent service-awareness function. Thus,resources allocation and transport policy are both determined only in ONUs. Simulation results show that the proposed mechanism is able to better support the ability of multiple services.展开更多
