    Adaptive bandwidth allocation algorithm based on the multi-threshold reservation mechanism by Geng CHEN, Wei-wei XIA, Lian-feng SHEN

    Published 2014-12-01
    “…An adaptive bandwidth allocation algorithm based on multi-threshold reservation mechanism is proposed to guarantee the quality of service (QoS) of multi-services in heterogeneous wireless networks.With the bandwidth reserva-tion mechanism by setting multi-threshold in each network for every traffic,the adaptive bandwidth allocation scheme according to the transmission rate levels requirements for traffic k and the network status can be formulated as an optimal problem with the constraints of the bandwidth allocation matrix for each traffic and all users based on the multi-homing technology.A procedure of the iterative method is presented to solve the optimal problem of the formulated adaptive bandwidth allocation scheme.The optimized bandwidth allocation matrixes for traffics and for all users are obtained for the real-time network throughput maximization under bandwidth reserving thresholds and network capacity constrains and the bandwidth resource utilization efficiency of heterogeneous wireless network can be increased.Numerical simula-tion results show that the proposed algorithm can support QoS requiring transmission rate grades,decrease the new call blocking probability,increase the average user access rate and improve the network throughput of the heterogeneous wireless network by 40% to the largest extent.…”

    Computing method for periodic stream reservation in TSN combined with SDN controller by Jianzhong SU, Huayu ZHANG, Hailong ZHU

    Published 2021-10-01
    “…In recent years, with the development of TSN, its low latency, low jitter and predictable maximum delay can be widely used in automatic driving technology and industrial Internet.To solve the 75% (empirical value) bandwidth problem of stream reservation technology in TSN protocols, and combine with the separation of data plane and control plane in SDN, a stream reservation solution was put forward, which was combined with TSN-SDN controller and scheduling the transmission path and reservation of the entire topology in the control plane.And two reservation computing methods was put forward, which would give out a bandwidth with time slot.The simulation experimental results show that it can control the jitter to 0 based on require latency, and also use the bandwidth based on time slot to guarantee the utilization of bandwidth.…”
