    Future IP network architecture evolution for service and network collaboration by Bing HUANG, Bin TAN, Jian LUO, Yong GUO

    Published 2021-10-01
    “…As the technical foundation of the internet, how IP technology develops in the next 5 to 10 years is the key issue facing the communication industry.The success and weakness of the traditional IP network architecture were analyzed, and the future IP network should not only inherit the design principles of the traditional IP technology was proposed, such as the end-to-end principle and layered decoupling principle, but also solve the problem that the service is too separated from the network.From the perspective of network evolution and future service requirements, the core issue of future IP networks is to strengthen the collaboration of between services and networks , and the improved IP network design principle “horizontal: end-to-end principle empowered by service-oriented network, vertical: layered model supported by intelligent control plane” was proposed, and based on this principle, the reference architecture of the future network was proposed.…”

    Temporal-spatial Evolution of Drought Characteristics at Different Grades in Yulin by KONG Gang, ZHANG Shanliang, WANG Lu, HUANG Shengzhi, BAI Jueying

    Published 2021-01-01
    “…Under the background of climate warming and human activities,Yulin city suffers from frequent drought,which has adverse effect on the agriculture,ecological environment and social economy in this area.Although the adverse effects of drought on the Loess Plateau have attracted the attention of many scholars,there is still a lack of grid and refined spatial and temporal assessment of drought in Yulin City.Therefore,taking Yulin City as the study area,based on the monthly precipitation and soil moisture data with a spatial resolution of 0.25°×0.25°,this paper calculates the standardized precipitation index (SPI) and the standardized soil moisture index (SSMI) on three month scales,identifies the drought characteristic parameters by the run theory,and analyzes the spatial-temporal evolution of drought characteristics at different grades.The results show that:The drought is rigorous in Yulin city.In time,a wet trend appears in spring and winter,while a dry trend in summer.In space,there is a significant dry trend in the southern of Yulin city.There are more than 6 months of long-term precipitation deficit and 12 months of long-term soil moisture deficit in Yulin City,respectively,and the month with consecutive precipitation deficit come earlier than the soil moisture deficit.Areas with high drought frequency are located in the northern,southern and eastern edges of Yulin.The conclusion is of great significance to the drought prevention,social production and ecological environment in Yulin city.…”

    Architecture evolution and bandwidth analysis of 5G bearer networks by Chunhua ZHAO

    Published 2019-02-01
    “…The influence of 5G mobile network architecture evolution on bearer network was demonstrated.A comparison of fiber requirement between 5G front-haul network and fixed broadband access network was proposed.The various bearer schemes in fiber shortage area were introduced.The characteristics of various device networking solution were summarized.The influence on bearer network architecture and bandwidth was analyzed when 5G core network moved down to the metro core DC and metro edge DC.The bandwidth calculation model on mobile metro mid-haul and back-haul network was presented.Bandwidth calculations on each layer of the networks were provided.Calculation results show that compared with 4G network,bandwidth requirements on bearer back-haul network are greatly increased as the bandwidth of the wireless side of the 5G network increases.The growth trend of the metro back-haul and export bandwidth is slowed down with the core network moving down and the deployment of CDN and MEC.…”
