    Reliable transmission mechanism with differentiated protection in virtualized fiber-wireless access network by Ruyan WANG, Yishuang GAO, Xiao CHEN

    Published 2019-03-01
    “…In view of the different reliability requirements of network service,a reliable transmission mechanism with differentiated protection was proposed in virtualized fiber-wireless access network.The quality of protection required by users and the fees that can be paid were used as a prerequisite.The backup protection resources were flexibly allocated by quantifying the multi-level protection quality with the probability of recovery.Then,for reducing traffic congestion and the unprotected services,the level service differentiation algorithm was used to choose protection link which was satisfied with the level of protection quality.The results show the proposed mechanism has more advantages in terms of long-term benefit-to-cost ratio and underlying network resource overhead,and provides users with a more flexible virtual network transmission while satisfying users’ reliability requirements.…”

    Research on Coded Caching-Enabled Cooperative Transmission Mechanism in LEO Small Satellite Network by Jian LI, Kaiping XUE, Hancheng LU

    Published 2021-06-01
    “…Along with the rapid development of low earth orbit (LEO) small satellite network, users can access content retrieval service through dense-deployed LEO satellite networks in the future.Due to the long propagation delay of satellite-to-terrestrial link, and also the constraint of limited communication resource and energy resource, it is diffi cult for satellites to provide effi cient content transmission service when facing the pressure of onboard overhead.A coded caching-based cooperative transmission mechanism was proposed in dense-deployed LEO small satellite network to achieve effi cient content distribution.By adopting fi ne-grained coded caching scheme, users could simultaneously receive cached packets from multiple LEO satellites to mitigated the cost of satellite backhaul link and improved the caching effi ciency.The simulation results showed that, after deploying onboard caching, the cost of content transmission could be reduced at least 39%.When coded caching-based transmission scheme was adopted, the cost of content transmission could be further reduced by 9%-42% with the increase of satellites providing cooperative transmission.…”

    QoE-aware video cooperative caching and transmission mechanism based on TWDM-PON and C-RAN by Dapeng WU, Xue LI, Hongxia LI

    Published 2019-03-01
    “…The quality of user experience suffers from performance deterioration dramatically due to the explosively growing data traffic.To improve the poor performance of cell-edge users and heavy-load cell users,which caused by dense network and load imbalance respectively,an QoE-aware video cooperative caching and transmission mechanism in cloud radio access network was proposed.Cooperative gain-aware virtual passive optical network was established to provide cooperative caching and transmission for video streaming by adopting collaborative approach in optical domain and wireless domain.Furthermore,user experience for video streaming,bandwidth provisioning and caching strategy were jointly optimized to improve QoE,which utilized the methods of dynamic caching in optical domain and buffer level-aware bandwidth configuration in wireless domain.The results show that the proposed mechanism enhances the quality of user experience and effectively improves the cache hit rate.…”
