Embodiment
The present invention has provided a kind of device of automatic adjustment bandwidth, can monitor transmission network and professional situation by this device, and adjust tactful according to the good bandwidth of prior formulation, when network, business and other condition reach the condition of adjusting strategy, just send bandwidth adjustment order automatically, carry out the auto-bandwidth adjustment.
With reference to the accompanying drawings, the preferred embodiments of the present invention are done detailed description.
With reference to shown in Figure 1, the device that the present invention adjusts bandwidth automatically comprises policy manager, strip width controller, monitor.
The tactical management management to as if the adjustment strategy of service bandwidth.So-called adjustment is tactful, adjusts the rule of bandwidth exactly, and promptly the bandwidth that certain is professional is adjusted into predetermined bandwidth under satisfied situation about imposing a condition.
For example, adjust theing contents are as follows of strategy:
| Business object | The target bandwidth | Condition |
| Professional A | 2M | Time＝PM12:00 |
| Professional A | 10M | Time＝AM7:00 |
| Professional B | 5M | This professional statistic flow in duration T 1＜3M |
| Professional B | 10M | This professional statistic flow is in duration T 1〉5M |
Wherein one adjusting strategy is: at PM12:00 the bandwidth of professional A is adjusted into 2M.The function of policy manager is adjusted strategy to these exactly and is carried out storage and maintenance, comprises functions such as increasing strategy, deletion strategy and modification strategy.Network management system can by and policy manager between interface realize policy manager is managed.
For the policy condition that defines in policy manager, needing device can monitor the pairing monitoring target of the parameter of these conditions.The function of monitor is exactly to finish such function, and monitoring target is monitored in real time, and monitoring target can be the present flow rate of current time, access service, whole network bandwidth load or the like, and monitoring result will be offered strip width controller.In order to reduce the data volume that monitor reports to strip width controller, monitor can be provided with some conditions to monitoring result, when monitoring result satisfies condition, Cai monitoring result is reported strip width controller.In a system, monitoring target may be varied, so the form of monitor also is various, can be a hardware unit, also can be the software module that can carry out certain function, and can distribute dispersedly as required.
Strip width controller is the self-adjusting control unit of bandwidth, it receives the Monitoring Data that monitor reports, adjust strategy according to the bandwidth that defines in the policy manager, judge whether current situation satisfies the bandwidth regularization condition of adjusting tactful defined, if condition satisfies, then automatically send corresponding business bandwidth adjustment order, thereby realize that network based strategy automatically adjusts professional bandwidth to control system.
The self-adjusting process of bandwidth is as follows:
The first step: the webmaster personnel formulate bandwidth by network management system and adjust strategy, by and policy manager between interface this bandwidth adjustment strategy is kept in the policy manager.
Second step: monitor monitors and bandwidth are adjusted the pairing monitoring target of conditional parameter of strategy.
The 3rd step: monitor reports strip width controller with the Monitoring Data that obtains.
The 4th step: the adjustment strategy of preserving in the strip width controller fetch policy manager.
The 5th step: strip width controller is checked Monitoring Data, judges that whether current situation satisfies the bandwidth regularization condition of adjusting tactful defined, if condition satisfies, then sends and adjust tactful corresponding service bandwidth adjustment order to control system.
The 6th step: control system receives the bandwidth adjustment order that strip width controller sends, and by signaling and route, is transmitting the adjustment that realizes service bandwidth on the network.
Below in conjunction with Application Example, technical solution of the present invention is described further.
Embodiment one

Then, bandwidth adjustment strategy is kept in the policy manager.
2, be provided with control module in the network management system, this control module is the current time of monitoring system in real time, if the current time to 12:00 at midnight, is then sent the control signaling that to adjust professional A bandwidth be 2M to control plane; If the current time is to 7:30 in the morning, then send the control signaling that to adjust professional A bandwidth be 10M to control plane.
This control module has realized the function of monitor and strip width controller.
3, control system receives network management system and sends the control signaling, by signaling and route, realizes the adjustment of professional A bandwidth on transmission equipment.
Embodiment two
With reference to shown in Figure 3, automatically adjust professional bandwidth according to the real-time traffic of business.
Flow to business is added up, and is less when the access service flow, when reaching the limit of regulation, automatically bandwidth is reduced to the numerical value of appointment.If flow continues to recover to increase, then bandwidth is reverted to the numerical value of deciding through consultation in advance automatically.
The steps include:
1, the webmaster personnel formulate bandwidth by network management system and adjust strategy.
The content of bandwidth adjustment strategy comprises: when the statistic flow of professional A in 5 minutes duration＜2M, then its bandwidth is adjusted into 5M; If its statistic flow is in 5 minutes duration〉5M, then its bandwidth is adjusted into 10M.
Then, this bandwidth adjustment strategy is kept in the policy manager.
2, transmission equipment is provided with the service bandwidth monitoring device, and this service bandwidth monitoring device can monitor and add up the flow of business.In the present embodiment, this service bandwidth monitoring device reports strip width controller with the service traffics statistical information of professional A.
This service bandwidth monitoring device has been realized the function of monitor.
3, be provided with strip width controller in the control plane, strip width controller obtains bandwidth and adjusts strategy from policy manager, and analyzes the service traffics statistics that the service bandwidth monitoring device reports.
If the statistic flow of the professional A that reports in 5 minutes all＜3M, then send and adjust professional A bandwidth the control signaling that is 5M; If the statistic flow of the professional A that reports in 5 minutes all 5M, then send and adjust professional A bandwidth the control signaling that is 10M.
Strip width controller will be adjusted the bandwidth signaling and send to the connection controller, thereby finish the adjustment of bandwidth.
4, control plane receives the control signaling, by signaling and route, is transmitting the adjustment that realizes on the plane at professional A bandwidth.
