Abstract
A control method for closed-loop feedback in IP network service quality management system is to acquire the operation state data of IP network with a network test device and further to analyses the network designed decisive data got by them then to adjust the IP network to judge if it receives new user service, namely, every user service should be permitted by the access control device before it enters into IP network and the base of the acc control device is got by real-time acquisition, analysis and design to the network actual operation state parameters. The closed-loop feedback includes two methods: a flow design and a network bottle-neck bandwidth design.
Description
Technical field
The present invention relates to the control method and the device of IP network service quality, exactly, relate to the control method and the device of closed loop feedback in a kind of IP network service quality administrative system, belong to network interconnection communication technical field.
Background technology
IP network especially is deployed in 3G or the soft switchcall server as the IP network of bearing bed, and is in large scale, and network service quality required harsh.But the transfer of data of traditional IP network (Internet) adopts the strategy of doing one's best, and can't realize differentiated services.
In order to address this problem, the IETF of International Standards Organization has proposed technology such as DiffServ system, IntServ system and MPLS-TE, is used to the business that realizes that service quality guarantees.Wherein the principal character of DiffServ system is that the flow in the IP network is classified, and different forwarding strategies is taked in different classification, thereby embodies the service quality difference of dissimilar flows.The principal character of IntServ system is to set up a virtual circuit by signaling between network end-to-end, this virtual circuit has certain bandwidth and time delay to guarantee, all routers relevant with this virtual circuit all will be kept the state information of this virtual circuit, up to its destruction.The principal character of MPLS-TE technology is at network edge mark message, and when the router of message passing through network core, these routers are only transmitted at the second layer of OSI seven layer reference model; The TE technology is the flow of automatic equalization given link in the network of having disposed MPLS then.How specifically above-mentioned IntServ and DiffServ System Framework have all just illustrated the enforcement target of this system and network to its support that should provide, do not have the explanation technical measures of enforcement.Present existing embodiment all be by the people network state is estimated after, adjust operation by manually finishing again.
But, make IP network that service quality guarantee can be provided, must in time find bottleneck link and bottleneck node on the network, and can adjust these bottleneck links and bottleneck node in real time, comprise and adopt the resource using method etc. of updating the equipment or planning bottleneck again.Present this artificial adjustment operation is impossible realize this target.In addition, after IP network deploy DiffServ system (comprising DiffServ system and any other technology of adopting of mixing), also need to adjust in real time the bandwidth of different flow class on the link according to network operation situation.But, in network in large scale, how to carry out network monitoring, and infer network operation state according to monitored results, then adjust network, to improve network operation efficient and to guarantee service quality, if these a series of tasks are very difficult and mysterious by manually finishing just.
Summary of the invention
The control method and the device that the purpose of this invention is to provide the closed loop feedback in a kind of IP network service quality administrative system, this method is according to cybernatic principle, the running state parameter that measures Network Based, automatic feedback adjusting and allocation of network resources, reduce in the present IP network service quality guarantee process and too rely on manually-operated present situation, to ensure professional service quality, make network be in the health status operation.
