The Design And Implementation Of Dynamic Bandwidth Control System

With the gradual emergence of Internet technology and a mixture of a variety of Internet information,the distribution of the Internet and the hierarchical nature of the Internet structure more and more significant.Network bandwidth congestion problems Since the development of the Internet with the existence of,in order to detect anomalies in the network,national researchers through data collection,collection and sampling analysis to know the operation of the Internet,the study of effective bandwidth control.Bandwidth management services enable users to understand the status of network resources,make full use of network resources,prioritize network access for key personnel,and prioritize critical application performance without the need to cycle through bandwidth resources.While achieving control of non-critical applications.Bandwidth management services allow users to understand the status of network resources,make full use of network resources,prioritize network access for key personnel,and prioritize critical application performance without the need to cycle through bandwidth resources.To achieve non-critical application control.The main purpose of this paper is to design and develop a complete set of dynamic bandwidth control system to improve the bandwidth control function in the firewall products.The goal of the project is to design and implement an application-based bandwidth control function based on the Linux X86 platform.Under a total bandwidth,dynamic bandwidth allocation is achieved according to the number of online users,so that each user can access the bandwidth Internet.Through this device,you can dynamically adjust the network bandwidth,static bandwidth allocation to solve the bandwidth waste,and through flexible configuration to ensure the bandwidth of critical applications.Based on the in-depth understanding of system design requirements,this paper realizes the interface of dynamic bandwidth control system,command-line development,kernel state exclusive,sharing strategy and queue scheduling algorithm.After the actual use of the system to prove that the system in line with the network operation and maintenance staff to work habits,the system also has a comprehensive design and implementation of the document,the system can be used in real-Under normal operating conditions,only a network configuration administrator to complete the routine maintenance work.
