【摘要】：随着移动互联网接入技术和移动通信技术的蓬勃发展,拥有LAN/WLAN/3G等多种网络接口的终端设备越来越普及,如何让不同的网络接口同时连接和使用成为一个重要的课题。本文针对拥有多个网口的移动终端设备接入代理移动IPv6网络的情况,设计和开发了一个基于代理移动IPv6的多连接管理系统。一个拥有多个网络接口的移动终端设备接入PMIPv6域,可能有多种业务流在不同的网络接口上传输。如何基于各条链路的网络状况和用户喜好,充分利用终端设备的多个设备接口,使得不同的业务流在接口间进行调控是多接口终端设备接入代理移动IPv6网络的重要研究方向。本系统实现了基于网络状况、各种业务流对网络状况的需求和用户策略,自动将业务流在终端设备的不同网络接口之间进行自动分配和调度的智能流控系统。为实现该系统,首先,要对基于代理移动IPv6协议进行相应的修改,实现对网络层的多连接和流移动性支持。其次,设计能感知和监测网络状况变化,及时感知各条链路的网络状况和进行策略的调整方法,以实现将用户策略转换为形式化的流调度规则,实现业务流的智能流控。最后,设计用户策略传送和智能流控功能,实现按照网络侧和用户策略综合的结果,把不同的业务流调整到最优的链路上进行传输,以达到高效利用网络资源的效果。本文设计的系统的创新点在于：在拥有多种网络接口的移动终端的不同网络接口同时接入不同或相同PMIPv6域后,能够依照各条链路的网络状况、用户策略和网络侧默认调度算法进行综合决策,自动把各种业务流调整到最优的路径上传输。
[Abstract]:With the rapid development of mobile Internet access technology and mobile communication technology, terminal devices with various network interfaces such as LAN/WLAN/3G are becoming more and more popular. How to connect and use different network interfaces at the same time becomes an important issue. A multi-connection management system based on agent mobile IPv6 is designed and developed. A mobile terminal device with multiple network interfaces is connected to the PMIPv6 domain, and there may be a variety of traffic over different network interfaces. It is an important research direction to make full use of multiple device interfaces of terminal devices to make different traffic flow adjust and control between interfaces. It is an important research direction for multi-interface terminal devices to access agent mobile IPv6 networks. This system realizes the intelligent flow control system which automatically distributes and dispatches the traffic flow among different network interfaces of terminal equipment based on the network condition, the requirement of various traffic flow to the network condition and the user strategy, in order to realize this system, First of all, the agent based mobile IPv6 protocol should be modified to support multi-connection and flow mobility in the network layer. Secondly, the design can perceive and monitor the changes of network conditions. In order to realize the conversion of user policies into formal flow scheduling rules, intelligent flow control of traffic flow is realized. Finally, the functions of user policy transfer and intelligent flow control are designed. According to the results of network side and user policy synthesis, different traffic flow can be adjusted to the optimal link for transmission, so as to make efficient use of network resources. The innovation of the system designed in this paper is that after the different network interfaces of mobile terminals with multiple network interfaces are connected to different or the same PMIPv6 domains simultaneously, they can be based on the network conditions of each link. The user policy and the default scheduling algorithm on the network side make a comprehensive decision and automatically adjust the traffic flow to the optimal path for transmission.
