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

The results are as follows: (1) Generally fine and uniform, grain-size charac- teristics of the reticulate red clay in Xuancheng and Jiujiang are much similar, with no >2 mm gravels, 0.30% and 1.14% of >63 μm fraction on average, respectively, and 34.65% and 37.20% of 10―50 μm fraction, which is apparently accumu- lated. The patterns of the grain-size distribution curves of the uppermost yellow-brown earth of the profiles in the two ar- eas much resemble those of the loess in northern China and the Xiashu loess in southeastern China, while the patterns of the other layers also apparently show some attributes inher- ited from the above. The grain-size distribution patterns of the quartz separated from the whole profiles in the areas are almost identical, which could also be compared with those of the loess and the Xiashu loess. All the features above reveal aeolian characteristics of the reticulated red clay in these two areas. (2) The reticulate red clay in Taihe and Ganzhou is much coarser than that in Xuancheng and Jiujiang, with high content of >63 μm fraction and relatively low content of 10―50 μm fraction. The variations in grain-size distribu- tions of the profiles are also observed. The grain-size distri- bution patterns of both the original samples and the quartz of the red clay could hardly be compared with those of the loess and the Xiashu loess. All the features above reveal their alluvial or diluvial origins. (3) The multiple origins of the reticulate red clay in the areas reflect the diversity and com- plexity of the Quaternary environment in southern China. The existence of the reticulate red clay with aeolian charac- teristics brings forth objective evidence for the occurrence of large-scale dust deposition in southern China during the Quaternary glacial periods. Further investigation and study on the regional distribution of this kind of the red clay will be conducive to revealing the southern border of the large-scale dust deposition in southern China during the Quaternary glacial periods.展开更多
