Control Of Network Behaviors And Research Of Related Key Algorithms

With the rapid development of network technology,more and more network applications imerge and bring us convenience and entertainment.But at the same time,these applications takes up too match network bandwidth.If we do not control the user's network behavior,network bandwidth will be inundated by such P2P,IM protocols.And finally these applications will affect normal ones.This dissertation studied the way to contol use's behavior in detail,and also resesarched and improved related algorithms.This dissertation stated the technologies which control user's network behavior of iptables,i.e,the linux firewall,and traffic management tool,TC.On this basis, this dissertation proposed overall functions and main framework of network behavior control system.At the same time,this dissertation analysed the problem of limit P2P protocols and the problem of network latency at the suffering peak, researched the related algorithms and implement them as extensions of iptables to effectively resolve these two issues.After research and implementation of these features,this dissertaton implemented a network behavior control system in detail.The creative works of this dissertation lists as fallows:Propose algorithm of connection limit.Propose an improved algorithm of speed limit.
