Description
Technical field
The present invention relates to internet arena, particularly relate to a kind of method and system of dynamic assignment network traffics.
Background technology
Network application at present more and more widely, yet but growing tension of bandwidth, this just requires IP network to provide better traffic management for the user, avoids flow misuse, abuse or waste.
At present the flow scheme that proposes mainly is based on the IP current limliting or based on Differentiated Services (DiffServ) two classes.The IP current limliting is the bandwidth constraints of the flow that passes in and out network being carried out up-downgoing by IP five elements (source address, destination address, source port, target port, agreement).This method is fairly simple, can't effective and reasonable distribution bandwidth in the time of still to IP address mapping or IP instability of flow.DiffServ mode assignment of traffic only is to come packet is treated with a certain discrimination according to the field of Differentiated Services, generally is at the existing protocol bag.There is the distribution error equally in dynamic network traffic/abnormal flow/unknown flow rate.
Prior art also provides a kind of scheme, mainly is packet is carried out user's classification and professional classification, forms data flow; Afterwards according to the flow of the categorical measures data flow of data flow; Again according to the resource on data stream type and the measurement result distribution buffer queue.But the traffic shaping of this scheme is based on the method for salary distribution under the known bandwidth situation.Frequently then inapplicable for unknown outlet bandwidth or outlet bandwidth conversion.As when exporting upstream and downstream bandwidth and becoming suddenly big, there is bandwidth waste; Outlet bandwidth diminishes suddenly, exists congested.
To sum up, because actual user's the complex nature of the problem, and the dynamic change of the network bandwidth, make prior art can't avoid bandwidth waste or congestion phenomenon.
Summary of the invention
The invention provides a kind of method and system of dynamic assignment network traffics, in order to solve under the situation of network bandwidth dynamic change, prior art can't be avoided the problem of bandwidth waste or congestion phenomenon.
The method of a kind of dynamic assignment network traffics of the present invention comprises the following steps: monitoring step: regularly the gateway outlet bandwidth is monitored, obtain current band data; Calculation procedure:, calculate the flow that each flow uses the unit to be assigned to from current bandwidth according to assignment of traffic strategy and the heavy allocation algorithm of flow; Heavy allocation step: use unit dispense flow rate again for each flow according to the aforementioned calculation result.
The system of a kind of dynamic assignment network traffics of the present invention comprises: monitoring modular, be used for regularly the gateway outlet bandwidth being monitored, and obtain current band data; Computing module is used for calculating the flow that each flow uses the unit to be assigned to according to assignment of traffic strategy and the heavy allocation algorithm of flow from current bandwidth; Heavy distribution module, the result of calculation that is used for drawing according to computing module is used unit dispense flow rate again for each flow.
Beneficial effect of the present invention is as follows:
Because there is the mechanism of periodic monitor gateway outlet bandwidth in the present invention, and calculate the flow that each flow uses unit to be assigned to from current bandwidth, finish flow afterwards and heavily distribute according to assignment of traffic strategy and the heavy allocation algorithm of flow.So the present invention can realize the dynamic assignment network traffics, the effective and reasonable bandwidth of utilizing is avoided bandwidth waste or congestion phenomenon.

Embodiment
For under the situation of network bandwidth dynamic change, the effective and reasonable bandwidth of utilizing is avoided bandwidth waste or congestion phenomenon, the invention provides a kind of method and system of dynamic assignment network traffics.Below specify by some embodiment.
Embodiment 1, referring to shown in Figure 1, the method for the dynamic assignment network traffics in the embodiment of the invention comprises following key step:
S1, timing are monitored the gateway outlet bandwidth, obtain current band data.
S2, according to the heavy allocation algorithm of assignment of traffic strategy and flow, calculate the flow that each flow uses unit to be assigned to from current bandwidth.
S3, be that according to the aforementioned calculation result each flow uses unit dispense flow rate again.
Above-mentioned flow uses the unit to be unit with the IP address, promptly to legal and need the utilizable flow of each IP address of flow control to adjust, distribute; Be unit perhaps, promptly come packet is distinguished, and the utilizable flow of each quasi-protocol packet is adjusted, distributed according to the field of Differentiated Services with the protocol package classification behind the Differentiated Services DiffServ.
Embodiment 2, based on embodiment 1, referring to shown in Figure 2, control is described in further detail at the flow process of IP address.
At first need the whole network IP or need the IP of Flow Control to carry out the IP-MAC binding, and record, prevent that IP from usurping;
When the packet secondary IP address is sent out outward, at first tested in the IP address, if illegal IP or the IP (promptly the MAC Address of this current correspondence in IP address and the binding information of record are not inconsistent) that usurps, then packet loss is handled; If normal IP traffic (MAC Address of this current correspondence in IP address conforms to the binding information of record) then continues;
Regularly the gateway outlet bandwidth is monitored simultaneously, (for example, 5M uploads, and every calibration in 10 seconds once, the bandwidth of bandwidth calibration back time point t1 and t2 is respectively b1=3M, b2=6M) to obtain the most approaching current band data;
(can certainly change the assignment of traffic strategy according to former assignment of traffic strategy, use new assignment of traffic strategy) and the heavy allocation algorithm of flow, (for example readjust the assignment of traffic of this IP, the former assignment of traffic of this IP is 1M, if heavy allocation algorithm is increase and decrease in proportion, then the heavily distribution bandwidth at t1 and t2 time point is ip_b1=0.6M, ip_b2=1.2M).Annotate: it only is for example that the heavy allocation algorithm of flow herein increases and decreases in proportion, can adopt the algorithm of more realistic demand in the practical application.
In like manner, also can adopt above-mentioned flow process to realize the dynamic assignment network traffics, repeat no more for the agreement of DiffServ.
