    QoS routing algorithm based on multiple domain architecture of SDN by Wei HUANG, Ran LU, Cuncai LIU, Sibo QI

    Published 2019-10-01
    “…Traditional distributed network architecture constraints the innovation of routing algorithm.Software-defined network (SDN) provides a new solution for the optimization of routing algorithm.Previous researches show that the quality of service (QoS) routing issues are based on heuristic algorithm mostly,but these methods cannot be applied in large networks due to their high computing complexity.However,other algorithms have a lot of problems,which are high complexity or poor QoS performance,such as shortest path algorithm.This paper proposes A new QoS routing algorithm:LC-LD routing algorithm was proposed.LC-LD was based on SDN west-east interface and binds both delay constraint and cost constraint.keeping a good balance between computational complexity and algorithm performance.Finally,the simulation results show that LC-LD can possess both low computational complexity and high QoS routing performance.…”

    Planning approach of survivable fiber-wireless broadband access network by Hongjun TAN, Yamin XIE, Yejun LIU

    Published 2016-05-01
    “…The emerging fiber-wireless(FiWi)broadband access network provides not only the new technological references for flexible broadband access anywhere and anytime,but also the research opportunities for the cost-efficient design of survivable broadband access network.The study of survivable FiWi access network planning was focused on,and an approach of survivable network planning based on wireless-rerouting protection was proposed.When any fiber link cuts,the failed optical network unit(ONU)can transfer its traffic into other normal ONUs.Solving the joint optimization problem of wireless routers placement,backup radios configuration and ONU capacity allocation was put more importance on,aiming to fully protect all traffic with the minimum deployment cost.The method of integer linear programming was employed to obtain the optimal solution for small-scale network planning.The heuristic algorithm was also proposed for the large-scale network planning.Simulation results demonstrate the effectiveness of the proposed approach in reducing network deployment cost.…”
