The Multi-Connection Communication Of Mobile Terminal Based On Vector Network

With the development and popularization, the Internet has gradually become an indivisible part of our social life. The IP network, which is based on the’end-to-end, connectionless, best-effort’technology, has become the mainstream of the Internet world. However, with the development of HDTV, webcast, intelligent hardware and other business as well as the arrival of the era of 5G, IP network based on traditional concept of design cannot meet the requirements of high speed and high reliability. Because of its shortest path routing policy and destination address forwarding mechanism, IP network has only one path during the routing stage. The problems including the decrease of network transmission rate, fault recovery delay, unbalanced network load. In recent years, researchers in the communication networks field were constantly thinking about solutions to the problem. However, under the premise of not changing the network architecture, the above problems cannot be solved perfectly. Under this circumstance, the development of next generation of Internet has become the common wish of the people throughout the world. As the leader of next generation of Internet, vector network makes a positive exploration. Vector network is located in the third layer of the seven layer model of OSI network. It is a new kind of data communication network. The transfer plane is separated from the control plane. And the so-called "Vector-Connection" is set up by calling and routing. The network system can realize multi path routing, which can achieve the communication effects of "multi connection".In this paper, Android phone is the research object of study and the multi path connection of vector network is the core theoretical foundation. We set up a small-changed, merging with IP network and complete communication platform of the vector network. The platform includes three important modules as follows:vector terminal application, vector switching applications and vector network controller. The platform intercepts the network data packets in the internal application of mobile phones and forwards the vector routing by Linux Iptables. The platform separates 3G network card and Wi-Fi network card in mobile phone by Linux Network Namespace. The 3G network card and Wi-Fi network card are simulated as different export of vector exchange. In this way, the platform realizes the research result of switching path manually or automatically between the two mobile terminals. Also, the function of multi-path connection is realized. Under the condition of being compatible with IP network, the communication effect display of a higher QoS and higher robustness of the multi-path connection communication based on vector network verifies its multi-path ability and excellent effect. Also, the feasibility of the gradual convergence of vector network and the existing network technology is proved.On the one hand, the vector network platform built in this paper provides a network layer solution for real-time information communication. It realizes soft handoff of communication in the case of users’transparent operation. At the same time, it provides theoretical support for enhancing the robustness, stability and improving performance of network communication. On the other hand, the research result of this paper is an important practical application since vector network and IP network integration theory are proposed. In the application of vector network theory, it is a very important step.
