【摘要】 无线局域网作为通信技术的重要组成部分，随着场景及应用环境不断演进，网络路由协议成为网络传输质量的关键，为此对无线局域网多域间端到端安全重路由协议进行研究。针对期望传输次数进行优化，并作为路由度量设计了宽带估计算法。按接口层、数据层和管理层对端到端安全重路由系统进行设计，根据配置接口层，增加新的模型定义，使系统具有灵活扩展性，可支持多种配置工具。为避免用户网络节点等问题导致原有路由失效，进行重路由操作，为了保证重路由请求具有唯一性，网络节点依据ID判断是否需要发起重路由。在满足用户网络多域间端到端安全的前提下，分别对链路复用率和重路由路径构建时间进行最大化和最小化处理。实验结果表明，所提安全重路由机制在不同流量等级和多种路由请求下，重路由成功率较高，而且具有较高的重路由寻路径效率。更多还原

【Abstract】 WLAN is an important part of communication technology, with the continuous evolution of scenarios and application environments, network routing protocol has become the key to network transmission quality. Therefore, the end-to-end secure rerouting protocol between multi-domains of WLAN is studied. The expected transmission times are optimized, and a broadband estimation algorithm is designed as a routing metric. Then, the end-to-end secure rerouting system is designed according to the interface layer, data layer and management layer. According to the configuration interface layer, a new model definition is added, so that the system has flexible scalability and can support a variety of configuration tools. In order to avoid the failure of the original route caused by problems such as user network nodes, the rerouting operation is carried out. In order to ensure the uniqueness of the rerouting request, the network node judges whether to initiate rerouting according to its ID. On the premise of meeting the end-to-end security of multi-domain user network, the link reuse rate and reroute path construction time are maximized and minimized respectively. Experimental results show that the proposed secure rerouting mechanism has high rerouting success rate under different traffic levels and multiple routing requests, and the rerouting time is very short.更多还原
