Design And Implementation Of A Grid System For The Analysis Of Network Traffic

With the rapid development of science and technology in the information area, the computing speed of computers, the communication capacity of networks and the storage capacity of storage devices have all become bottlenecks for nowadays implementation requirements. At the same time, with the new application development based on Internet, the types of network protocols have become increasingly day by day. To rapid and effective identify the various protocols of the networks, became the ISP and network managers to monitor, adjustment and upgrade of network equipment and management of important reference tool.Although the existing traffic analysis system resolved some relevant issues, but there are also many inadequacies. Such as the existing identification system, because the defective of algorithm or the lack of support for the new protocols, making identification results in the "other category" type of data can even account for 50% of the proportion of the loss of significance. At the same time, with the ever increasing of network bandwidth, and the lower efficiency of the implementation of procedures need to use up a lot of computing resources have become unable to overcome the problem of existing hardware in the level of speed has been unable to withstand the flow of more than 10 Gigabit bandwidth identification. Finally, most of the traffic analysis systems are often only for a specific platform, even if the occasional support of the system of multi-platform also failed to achieve real meaning of the cross-platform, but only introduced for different platforms with a tool, not the effect of recognition satisfactory.For the above deficiencies, and in recent years, the grid platform to address the issue of this series provides a new way of thinking. Grid is the use of the Internet on the wide geographical distribution of various resources (including computing resources, storage resources, bandwidth resources, software resources, data resources, information resources, knowledge resources, etc.) as a single logical entity, formed a supercomputer, To provide users with information and application integration services, and eventually realize in this virtual environment for the sharing of resources and work together. Grid platform for the traffic analysis system can provide a powerful computing resources and storage resources, while grid platform is the true sense of the boast platform system that can well support, including Windows, UNIX, the various operating system platforms. Grid characteristics of this series for the current lack of traffic analysis system provide solutions for the realization of more than 10 Gigabit traffic analysis systems laid the foundation.In this issue of the existing traffic analysis system and the mainstream in recent years, the grid architecture, through access to grid areas of the relevant circumstances at home and abroad, details of the current grid of the actual standards - Globus tool kit of the use and development Application of the process, and on the basis of this programming in the face of network traffic analysis of the grid system development and call. Finally, the entire system as well as a summary of room for improvement deficiencies.
