The Data Transmission System Based On IPFIX Protocol

To the healthy development of the Internet network traffic monitoring system has become a natural product, it can make timely and accurately flow analysis of the network.Network communication technology is the most crucial technology in the remote monitoring technologies. however, the general communications network uses simple Socket technology, and even FTP or Email, and these technologies work not well both in the amount of data transmission, programming flexibility or security aspects, particularly for the scene of a number of endpoint data acquisition. It would greatly increase the complexity of programming, and remote monitoring technology can not meet the demand for network communications. So network administrators are free to add or change the domain (the specific parameters and agreements) in order to more easily monitor IP traffic information. To unpredictable changes in the network, managers will be able to adapt quickly to amend Any network situation without a lot of software changes.The author's work and innovation include:1. First make IPFIX protocol as communication protocol of network monitoring system to complete the data transimission between client and server, greatly enhancing the flexibility and scalability of communications networks;2. Using multi_thread technology in the client to effectively improve the efficiency of coding and sending;3. An effective solution to the problem of communication security of the monitoring system.4. This system is developed as a sub system of 3Tnet Monitor system, and it works effectively.
