中文摘要： 本课题研究基于网络编码和多速率组播的多业务系统（MSNCM）的流量分配和公平性问题。 1. 基于层间网络编码技术，研究多速率组播通信的流量分配问题，提出物理意义清晰且满足收敛性、稳定性要求的分布式流量分配算法，利用Lyapunov定理证明所提算法的稳定性；2. 研究基于网络编码和多速率组播的多业务系统的流量分配问题，推导多速率组播与其他业务进行网络编码的条件，以及当编码条件满足时为系统的流量分配问题提出物理意义清晰且满足收敛性、稳定性要求的分布式算法；3.研究基于网络编码的多速率组播网络内不同用户之间的公平性以及MSNCM中当业务间存在网络编码时的公平性，通过以公平性为优化目标建立相应的优化模型，针对此类优化模型，利用博弈论和蚁群算法提出业务内/间的满足公平性要求的复杂度合理的分布式流量分配算法。

英文摘要： This topic researches the problems of flow distribution and fairness for multi-service system based on network coding and multi-rate multicast(MSNCM). Firstly,based on the inter-layer network coding techniques,the topic studies the flow distribution problem for multi-rate multicast communication,puts forward the distributed flow allocation algorithm with the clear physical meaning that satisfies the convergence and stability requirements,and using Lyapunov theorem proves the stability of the proposed algorithm. Secondly,the topic studies the flow distribution problem for multi-service system based on network coding and multi-rate multicast, derives the conditions that allow the multi-rate multicast services and other services to conduct network coding,and provides the distributed algorithms that has the clear physical meaning and satisfies the requirements of convergence and stability to solve the problem of flow distribution for the system when the conditions are satisfied. And thirdly,the topic considers the fairness between the different users for the network coding-based multi-rate multicast network and the fairness of MSNCM when network coding exists between the services which are belonged to MSNCM.The fairness are considered as the optimization targets to establish the corresponding optimization models.In
