Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Execution mode described in following exemplary embodiment does not represent all execution modes consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
Disclosure embodiment provides a kind of method of allocated bandwidth, can be used for the network equipment such as router etc. with routing function and allocated bandwidth function, as shown in Figure 1, and the method comprising the steps of S11-S13:
In step s 11, judge whether there is default key service in the network service of current operation; Wherein, in disclosure embodiment, key service is the network service of real-time bandwidth value abnormal running when being less than preset value; When judging to exist, continue to perform S12, otherwise flow process terminates;
In step s 12, the bandwidth needed for described key service is determined;
In step s 13, for key service correspondence distributes the bandwidth needed for it.
Respectively above steps is described in detail below.
In the disclosed embodiments, key service pre-sets, and key service is the network service of real-time bandwidth value abnormal running when being less than preset value, and key service has following feature:
On the one hand, if allocated bandwidth is not enough, Consumer's Experience extreme difference can be caused, such as once allocated bandwidth is not enough, time delay and Ka Dun will be produced, the experience of extreme influence user, even whole network service can not normally carry out, such as online video playback service, game on line service etc.And other service such as data upload download service etc., when real-time bandwidth is slightly not enough, user does not have perception strong especially.
In addition on the one hand, key service, also usually more paid close attention to (comparatively other network services) by user, such as when on user terminal during Multi net voting service operation, when such as operation simultaneously has game on line service and Online Music to serve, user can more pay close attention to online game services, and when such as operation simultaneously has Online Video to watch service and data download service again, user more can pay close attention to online video-see service.So, for such service, if allocated bandwidth is inappropriate, real-time bandwidth slightly not enough (being such as less than preset value), will bring tremendous influence to the experience of user, otherwise, if allocated bandwidth is rationally appropriate, the experience of user greatly can be ensured.
According to These characteristics, can pre-define one or more network service as key service, when this or these key service starts, the method for the allocated bandwidth that just can provide according to disclosure embodiment carries out allocated bandwidth.
Based on this, in disclosure embodiment, more pre-defined key service, and according to the feature of these key service, gather relevant technical parameter, these technical parameters are generated a technical parameter table, like this, when the network operation, just can pass through this technical parameter table, determine currently whether run default key service.
In one embodiment, said process can comprise the steps:
From the associated technical parameters list of pre-configured key service, judge whether each network service of current operation exists the technical parameter matched;
If exist, then judge that current operation has default key service.
Alternatively, the technical parameter in above-mentioned technical parameter list comprise following one or more:
The object IP address of network service, port numbers, the network address of website of accessing etc.
The address etc. of the IP of such as some game on line and port, video website, deposits associated technical parameters on the server, and, can according to the change of service, can carry out increasing, delete and the operation such as amendment.
In one embodiment, when key service be video playback service or picture browsing service time, in above-mentioned steps S12, determine the bandwidth needed for key service, as shown in Figure 2, can be realized by following step:
In the step s 21, according to the requirement of definition of video playback service or picture browsing service, the lowest bit rate of video data transmission is calculated;
In step S22, according to lowest bit rate, determine video playback service or the bandwidth needed for picture browsing service.
For example, the definition of video playback can have multiple dividing mode, such as according to the size of resolution, 1080P, 1080I, 720P etc. can be divided into, correspondingly can calculate the lowest bit rate of video data transmission, with 720p, the video of 8bit look is example, and the data volume that 1 frame can't harm broadcasting is 1280*720*8/8=921600Byte, with 25 frames per second, can calculate lowest bit rate is: 1280*720*8*25=184MBit/s, and then is converted into bandwidth.
For the such as key service such as video playback and game on line, its flow is generally stable, therefore the bandwidth taken also is stable, therefore, in one embodiment, intelligent learning can also be carried out, bandwidth value intelligent learning obtained, as the bandwidth value needed for this key service in advance to the key service that real-time bandwidth needed for those is stable.
Wherein, intelligent learning is carried out to key service and obtains bandwidth, as shown in Figure 3, can comprise the steps:
In step S31, for each key service, from the bandwidth starting point of setting, increase to the bandwidth that key service is distributed step by step;
In step s 32, monitor the actual bandwidth taken of key service, until when the actual bandwidth arrival point of safes taken of key service no longer continues to increase, using the bandwidth that this point of safes obtains as intelligent learning.
When the bandwidth needed for intelligent learning key service, the process of the intelligent learning of multiple service can also can not simultaneously be carried out simultaneously, and the process of each intelligent learning is similar, mutually independently, can obtain the bandwidth needed for each key service respectively.
When the process of intelligent learning just starts, first distribute little bandwidth resources, then progressively bandwidth is increased, the actual bandwidth taken of Monitoring Service simultaneously, until arrive certain point, even if increase the bandwidth of distribution again, and when the bandwidth that this service takies can not increase thereupon, so this service required for bandwidth be exactly this point value.The method of this intelligent learning, Reality simulation network condition, the bandwidth ratio needed for the service obtained is more accurate close to real situation.
When progressively increasing bandwidth, can increase according to the rule of setting, such as increasing according to the step-length of a setting, also can increase with larger step-length according to early stage, later stage increases with less step-length or conversely, etc., disclosure embodiment does not limit the rule increased.
Further, in network operation process, according to network actual conditions, the size of the pre-assigned bandwidth of key service can also be finely tuned, both ensure that the smoothness of key service is run until reach, be unlikely to again to waste limited bandwidth resources.
For game on line, by the amount of bandwidth that above-mentioned steps S11-S13 distributes key service, can ensure that its whole smoothness is run, for game on line, although its overall stability of flow, but also can there is the small leak of bandwidth once in a while, such as game is when more new scene, namely to transform to a background from a fixed scene (such as background for indoor) very abundant for game, dynamic scene (is such as transformed to outdoor, there are very many dynamic game elements outdoor), in this case, can be many due to the unexpected change of the content loaded, there is a slight bandwidth peak, like this, just can be in this case, on the bandwidth base of original distribution more dynamically overabsorption some, when game is got back to static again, in geostationary environment (such as game is walked about under fixing background), then can get back to original allocated bandwidth value or reduce a little again on the basis of the bandwidth of original distribution.The amount of concrete increase or minimizing, can determine with reference to the practical operation situation of difference service, also can with reference to empirical value.
Certainly, based on experience value, the amount of bandwidth needed for certain key service can also be determined.
In step s 13, for key service, need the bandwidth always ensured needed for the bandwidth of this service, to ensure that it runs.
For the non-critical services run (other network services except key service), that or those bandwidth shared by non-critical services deducts the bandwidth of distributing for key service for total bandwidth, in the bandwidth that these are remaining, when non-critical services has multiple, the mode of distributing bandwidth for each non-critical services is varied, can mean allocation bandwidth, also each service distribution strip tolerance volume can be respectively, or non-critical services is carried out the division of priority, distribute bandwidth etc. according to the height of priority, be not described in detail in this.
The method of the above-mentioned allocated bandwidth that disclosure embodiment provides, first judges whether there is default key service in the network service of current operation; When judging to exist, determine the bandwidth needed for key service; Then for key service correspondence distributes the bandwidth needed for it, to ensure that it runs.The method of salary distribution of above-mentioned bandwidth, take into full account the allocated bandwidth demand of those user's experiences to the service of bandwidth sensitive, ensure that these running qualities concerning very important key service Consumer's Experience, achieve smart allocation bandwidth, ensure user's experience, avoid the unreasonable harmful effect to Consumer's Experience of allocated bandwidth.
