Design And Implementation Of Nanjing Broadcasting Metropolitan Area Network Resource Optimization

The subject of this thesis is based on Nanjing Broadcasting MAN bandwidth bottlenecks in the actual operations, which analyzed the network optimization strategy of small operators, whose network bandwidth resources is short. And by given overall network optimization solutions, to design and implement traffic analysis and control system, Http cache acceleration system and P2P cache system. Traffic analysis and control system is for network traffic analysis, management and optimization control. Http cache acceleration system is for cache acceleration and secondary forwards of Http page resource, which can improve the user experience on Internet effectively. P2P cache system is for caching optimization of download resources, which can save network bandwidth resource significantly. After testing, analyzing and implementing of the three systems, we reached our goal to improve network quality and enhance user experience, and it also provides a reference instance of optimization of small network operators.The thesis is divided into six chapters, the main contents include the following:Chapter 1 introduces the background and significance of the subject, and briefly describes the main contents of this paper and section arrangements.Chapter 2 analyzes the Nanjing Broadcasting MAN current problems and solutions, gives a total solution, and decomposes into three relatively independent systems, traffic analysis and control system, Http cache acceleration system, and P2P caching system.Chapter 3 describes the theoretical basis of modern traffic control technology, design and implementation of traffic analysis and control system, and control strategy of the system.Chapter 4 describes the Http cache acceleration technology, design and implementation of Http cache acceleration system. Finally, an improved implementation is given after discussions about possible problems and related solutions.Chapter 5 describes the P2P caching technology, design and implementation of P2P cache system, and differences based on various protocols.Chapter 6 presents the test results and analysis of the three systems, further discussion and summary by combining the test results and present network.
