Android System Monitoring Network Date Flow Analysis And Research

With the installation of android mobile phone popularized and the coverage3G network improved, at the same time smart phones bring dripping fun of experience, while more and more mobile phone users also pay attention to the transfinite mobile surfer traffic problems. The "whopping price QQ" and "whopping price micro blog" and other traffic scandals which are exposed by media are once hotly debated by netizens. According to a web survey data shows that over70%of smart phones users who had inexplicable situation that mobile phone traffic is consumed unknowingly. Over40%of users said that their monthly mobile phone traffic is not enough, so who moved my data traffic, and who is the traffic killer? This article is based on android phone intelligent operation platform as research object, on the one hand, starting from the bottom packet capture and analysis filter of android system, use Libpcap library method leading to Android system, and capture and filter packets which flows the network card from the core layer. According to user-defined rules, grasp certain type protocol packet or some packets that match the characters to show out for users reference and analysis. Simultaneously, statistical data traffic for all network programs, calibrate its integration and conversion through different data form for mobile phone users consult. On the other hand, use the Iptables/netfilter methods in order to get the aim of control of networking data., through user-defined, modifying Iptables rules collection, adding a new rule chain, matching the parsed header data files with the modified rule collection, making a decision that whether data packet release or block in order to control program networking power. Eventually the two modules packet capture and traffic statistics integrate an easy use and good interface software. Users can base on different internet habits to personalize software custom settings and provide users with targeted traffic monitoring and overrun reminder service.Through experimental tests, the two software modules really achieve the aim of a single mobile application network access control and reminders for traffic monitoring data system, which to some extent can help android mobile phone users solve the problems of malware networking background and crazy traffic run by misusing.
