本文提出了一种新的架构，用于建立第二层虚拟专用网（VPN）的WiMAX和以太网无源光网络的集成，这是最近被认为是下一代光纤无线回程接入网的有前途的候选人。使用WiMAX-VPON，第2层VPN支持对相应注册无线/有线用户的一系列服务要求。这些要求在服务水平协议中有规定，应该通过一套有效的带宽管理解决方案来满足。为了实现这一目标，我们提出了一种新的基于VPN的准入控制和带宽分配方案，提供每流的服务质量保护和实时流的带宽保证。带宽分配通过在光域和无线域中工作的公共介质访问控制协议来执行。一个事件驱动的仿真模型来研究所提出的框架的有效性。
This paper proposes WiMAX-VPON, a novel framework for establishing layer-2 virtual private networks (VPNs) over the integration of WiMAX and Ethernet passive optical networks, which has lately been considered as a promising candidate for next-generation fiber-wireless backhaul-access networks. With WiMAX-VPON, layer-2 VPNs support a bundle of service requirements to the respective registered wireless/wired users. These requirements are stipulated in the service level agreement and should be fulfilled by a suite of effective bandwidth management solutions. To achieve this, we propose a novel VPN-based admission control and bandwidth allocation scheme that provides per-stream quality-of-service protection and bandwidth guarantee for real-time flows. The bandwidth allocation is performed via a common medium access control protocol working in both the optical and wireless domains. An event-driven simulation model is implemented to study the effectiveness of the proposed framework.
