摘　　要：隧道机制广泛应用于各种互联网传输场景,多径隧道则可以增大隧道传输带宽,提升隧道传输的可靠性和灵活性.然而,多径隧道网络环境中的传输路径优化控制也给网络管理带来了挑战.本文分析了多径隧道传输特征,基于多种网络性能指标提出了针对用户网络服务质量的隧道调度方法,并进一步设计最小化网关带宽利用率的流量均衡机制.而且,提出了3种针对多径隧道调度的具体实施策略.仿真实验表明本文工作能针对用户网络传输需求提供隧道传输服务,能够均衡多个隧道网关的传输负载.The tunnel mechanism is widely used in a variety of Internet transmission scenarios,and multipath tunnels can increase the tunnel transmission bandwidth and improve the reliability and flexibility of tunnel transmission.However,the transmission path control in the multipath tunnel network environment also brings challenges to the network management.This paper analyzes the characteristics of multipath tunnel transmission,proposes a tunnel scheduling method for user network service demands based on multiple network performance indicators,and further designs a tunnel scheduling mechanism based on bandwidth utilization.Moreover,three specific implementation strategies for multipath tunnel scheduling are proposed.Simulation experiments show that the work in this paper can provide tunnel transmission services for users′different network transmission needs,and balance the transmission load of multiple tunnel gateways.
