中文摘要：

选播是Ipv6中的一种标准通讯模型。本文研究多QoS参数约束的选播路由问题，建立了一种带有多个QoS参数约束的选播通信服务模型，设计实现了相应的多路选播路由算法。网络仿真实验结果表明，该算法是有效且切实可行的，它能同时满足多个QoS的约束条件，具有较好的求解效果，改善了网络服务质量。

英文摘要：

Anycast has been defined as a standard communication model of IP version 6. In tins paper, we research a multiple-constrained anycast routing problem, and establish an anycast service model with multiple QoS parameters constraint, and design and implement a new anycast multi-path routing algorithm based on genetic algorithm, The results of network experiment show that this algorithm is effective and available, and it can satisfy the constrained condition of multiple QoS at the same time and improve the network service quantity.
