为给不同的用户提供不同的服务质量(QoS),提出一种基于网边缘控制的因特网QoS路由算法。该算法中,路由选择的决断主要由网边缘做出,核心路由器的任务简化为通报网络信息和协调用户决断这两个较为简单的功能,利用用户级别的自组织路由来达到上述目标,从而形成一个扩展性强的自适应QoS路由算法。它使用路由探测分组与染色分组来增强网络的自适应能力;不需了解全局信息,只需局部网络状态即可;利用用户的自组织行为来协调路由行为。分析与仿真实验表明:该算法比传统算法有较强的动态性、可扩展性和较强的QoS提供能力。
In order to provide different users with different quality of service (QoS), an Internet QoS routing algorithm based on network edge control is proposed. In the algorithm, the decision of routing is mainly made by the edge of the network, and the task of the core router is simplified to two simple functions of informing network information and coordinating user decision, and using the user-level self-organizing routing to achieve the above goal A Scalable Adaptive QoS Routing Algorithm. It uses routing probing packets and coloring packets to enhance the network’s adaptive ability; without knowing the global information, only the local network status can be; using the user’s self-organizing behavior to coordinate the routing behavior. The analysis and simulation results show that the proposed algorithm has more dynamic, scalability and QoS capabilities than traditional algorithms.
