【摘要】：隨著移動互聯(lián)網(wǎng)接入技術(shù)和移動通信技術(shù)的蓬勃發(fā)展,擁有LAN/WLAN/3G等多種網(wǎng)絡(luò)接口的終端設(shè)備越來越普及,如何讓不同的網(wǎng)絡(luò)接口同時連接和使用成為一個重要的課題。本文針對擁有多個網(wǎng)口的移動終端設(shè)備接入代理移動IPv6網(wǎng)絡(luò)的情況,設(shè)計和開發(fā)了一個基于代理移動IPv6的多連接管理系統(tǒng)。 一個擁有多個網(wǎng)絡(luò)接口的移動終端設(shè)備接入PMIPv6域,可能有多種業(yè)務(wù)流在不同的網(wǎng)絡(luò)接口上傳輸。如何基于各條鏈路的網(wǎng)絡(luò)狀況和用戶喜好,充分利用終端設(shè)備的多個設(shè)備接口,使得不同的業(yè)務(wù)流在接口間進行調(diào)控是多接口終端設(shè)備接入代理移動IPv6網(wǎng)絡(luò)的重要研究方向。 本系統(tǒng)實現(xiàn)了基于網(wǎng)絡(luò)狀況、各種業(yè)務(wù)流對網(wǎng)絡(luò)狀況的需求和用戶策略,自動將業(yè)務(wù)流在終端設(shè)備的不同網(wǎng)絡(luò)接口之間進行自動分配和調(diào)度的智能流控系統(tǒng)。為實現(xiàn)該系統(tǒng),首先,要對基于代理移動IPv6協(xié)議進行相應的修改,實現(xiàn)對網(wǎng)絡(luò)層的多連接和流移動性支持。其次,設(shè)計能感知和監(jiān)測網(wǎng)絡(luò)狀況變化,及時感知各條鏈路的網(wǎng)絡(luò)狀況和進行策略的調(diào)整方法,以實現(xiàn)將用戶策略轉(zhuǎn)換為形式化的流調(diào)度規(guī)則,實現(xiàn)業(yè)務(wù)流的智能流控。最后,設(shè)計用戶策略傳送和智能流控功能,實現(xiàn)按照網(wǎng)絡(luò)側(cè)和用戶策略綜合的結(jié)果,把不同的業(yè)務(wù)流調(diào)整到最優(yōu)的鏈路上進行傳輸,以達到高效利用網(wǎng)絡(luò)資源的效果。 本文設(shè)計的系統(tǒng)的創(chuàng)新點在于：在擁有多種網(wǎng)絡(luò)接口的移動終端的不同網(wǎng)絡(luò)接口同時接入不同或相同PMIPv6域后,能夠依照各條鏈路的網(wǎng)絡(luò)狀況、用戶策略和網(wǎng)絡(luò)側(cè)默認調(diào)度算法進行綜合決策,自動把各種業(yè)務(wù)流調(diào)整到最優(yōu)的路徑上傳輸。
[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.
