Research Of Protocol Identification Model And Algorthm Based On Cloud Computing

With the development of information technology, network environment has become increasingly multiplex and complex. To promote and spread the critical business, it is an urgent need of various industries to classify and manage the network traffic with the help of protocol identification technology. Researches on protocol identification have important theoretical and practical value.Traditional protocol identification model with limits in structure and capacity cannot deal with growing number of volatile protocols. To optimize the traditional model, this paper has done researches in the following aspects:1. The paper summarizes the limitations of existing protocol identification technology. With introduction to cloud computing technology and its advantages, the paper analyses a cloud based protocol identification model.2. According to the limits in computing capacity, environmental flexibility and automatic learning ability, a protocol identification model based on cloud computing has been presented, of which the key models have been elaborated such as data processing, rule revision, cloud storage and computing model.3. The paper designs a rule tree organizing algorithm for needs in data processing and rule revision procedures. It applies mutation testing technology to test for variation of the rules with small deviation to be amended.4. The paper uses an example in designed model and algorithm to show that the protocol identification model can correctly find the modification of protocol's characteristic. And the introduction of optimized rule tree organizing algorithm can significantly improve the efficiency of the matching.
