It is understood that the functional software for realizing bandwidth allocation methods of the embodiment of the present invention can be to be arranged at the route Device dedicated for bandwidth allocation software, or be arranged at the function that the router is currently used in bandwidth allocation software and insert Part, this is all rational.

As shown in figure 1, the bandwidth allocation methods may include steps of：

S101：It is determined that multiple target access network equipments of current bandwidth to be allocated, wherein, the plurality of target access network equipment Include at least one video monitor；

Wherein it is determined that there is the target access network equipment of access network demand in current video monitoring system, that is, determine current The target access network equipment of bandwidth to be allocated.Wherein, the target access network equipment of current bandwidth to be allocated regards including at least one Frequency monitor, and all there is access network demand in the video monitor, the video monitor is monitored at any monitoring moment To video flowing be uploaded to high in the clouds.

Wherein, the video flowing that the video monitor monitors to obtain is uploaded into high in the clouds to refer to the video flowing being uploaded to net Network, and high in the clouds is existing concept, it is not described here in detail.

S102：According to the incremental order of the time delay value required by each target access network equipment, and from limit priority Start assignment principle, determine the bandwidth allocation priority of each target access network equipment successively, wherein, the time delay value is used to characterize The requirement of real-time of each target access network equipment access network, and the time delay value and the negatively correlated pass of bandwidth allocation priority System；

Wherein, it is determined that after each target access network equipment of current bandwidth to be allocated, accessed according to current each target Net equipment runs the requirement of real-time of business, determines the time delay value required by each target access network equipment；And according to each Time delay value required by target access network equipment, determine the bandwidth allocation priority of each target access network equipment, i.e., according to The order of time delay value from low to high required by each target access network equipment, sets to each target access network equipment successively Bandwidth allocation priority is put, can preferentially ensure the bandwidth allocation of the high target access network equipment of real-time demand, is improved Consumer's Experience.Wherein, the principle of setting bandwidth allocation priority is：The assignment since limit priority., wherein it is desired to explanation It is that the time delay value required by each target access network equipment can be set manually by user, or, implement according to the present invention is performed What the router that example provides method automatically determined out according to the device type of each target access network equipment, this is all reasonable 's.

For example, at the first moment, determining the target access network equipment of current bandwidth to be allocated in video monitoring system A has： Intelligent television, smart mobile phone and video monitor, and the smart mobile phone is 1 second to the time delay value required by access network network, intelligence Time delay value required by TV is 2 seconds, and the time delay value required by video monitor is 10 seconds, now may determine that the smart mobile phone Of a relatively high with the real-time demand of the intelligent television, the real-time demand of video monitor is relatively low；In addition, according to time delay Value order from low to high and the assignment principle since limit priority, the bandwidth allocation priority of the smart mobile phone is determined successively For 1, the bandwidth allocation priority of the intelligent television is 2, and the bandwidth allocation priority of the video monitor is 3, and sets the band Wide distribution priority belongs to limit priority for 1, and the bandwidth allocation priority belongs to lowest priority for 3, it is, time delay value With the negatively correlated relation of bandwidth allocation priority；

At the second moment, determining the target access network equipment of current bandwidth to be allocated in video monitoring system A has：Intelligence TV, tablet personal computer, smart mobile phone and video monitor, and the smart mobile phone is 1 second to the time delay value required by access network network, The time delay value that the tablet personal computer is allowed access network network is 1.5 seconds, and the time delay value required by intelligent television is 2 seconds, video prison Time delay value required by controlling device is 10 seconds, now may determine that the real-time demand of the smart mobile phone and the tablet personal computer relatively Height, the real-time demand of video monitor are relatively low；In addition, according to time delay value order from low to high and from limit priority Start assignment principle, the bandwidth allocation priority for determining the smart mobile phone successively is 1, the bandwidth allocation priority of the tablet personal computer For 2, the bandwidth allocation priority of the intelligent television is 3, and the bandwidth allocation priority of the video monitor is 4, and it is excellent to set this First level belongs to limit priority for 1, and the priority belongs to lowest priority for 4, it is, time delay value and bandwidth allocation priority Negatively correlated relation.

It is emphasized that it is merely exemplary to illustrate above, the restriction to the embodiment of the present invention should not be formed, That is the target access network equipment of identified current bandwidth to be allocated includes but is not limited to intelligent television, intelligent hand Machine, tablet personal computer and video monitor.

It will be appreciated to those of skill in the art that the equipment such as intelligent television and smart mobile phone is usually present download demand, And user is real-time, therefore right for the demand that the downloading datas such as game are seen a film, played using intelligent television or smart mobile phone It is higher to access the time requirement of network, that is, requires relatively low time delay value, and video monitor only exists uploaded videos and flow to high in the clouds Demand, the time requirement to access network network is relatively low, i.e., requires low to the time delay value of access network network.

S103：Bandwidth allocation priority and default first bandwidth distribution list according to each target access network equipment, Bandwidth is distributed for each target access network equipment, wherein, record has each bandwidth allocation preferential in first bandwidth distribution list Bandwidth allocation ratio corresponding to level；

Wherein, record has each bandwidth allocation priority, and each bandwidth allocation priority in the first bandwidth distribution list Corresponding bandwidth allocation ratio, for example, can record in the first bandwidth distribution list has 50 bandwidth allocation priority, wherein bandwidth Distribution priority belongs to limit priority for 1, and bandwidth allocation priority belongs to lowest priority, and bandwidth allocation priority for 50 1 to 50 corresponds to corresponding bandwidth allocation ratio, wherein, the bandwidth allocation ratio that bandwidth allocation priority is 50 can be 0, when So it is not limited thereto.

Bandwidth allocation priority that thus can be according to each target access network equipment and default first bandwidth distribution list In bandwidth allocation priority matched, and the bandwidth of each target access network equipment is determined according to priority matching result Allocation proportion, and distribute band to each target access network equipment according to the bandwidth allocation ratio of each target access network equipment It is wide.

It will be appreciated by persons skilled in the art that it is determined that the bandwidth allocation priority of each target access network equipment Afterwards, the bandwidth allocation of the target access network equipment of high priority, and the band of the target access network when high priority can preferentially be met After wide distribution requirements are met, then bandwidth allocation is carried out to the target access network equipment of next priority.

It is emphasized that the number of levels of bandwidth allocation priority can be according to setting in the presence of video monitoring system Standby quantity determines, because bandwidth is limited, therefore, in order to ensure the relatively low equipment of some institute's permissible delay values can normally on Net, that is, suitable bandwidth being assigned to, bandwidth allocation ratio corresponding to some other bandwidth difference priority possibility of lower level is 0, For example：The number of levels of bandwidth allocation priority is 20, is specially：1-20, and bandwidth allocation priority 1 is that highest is preferential Level, bandwidth allocation priority 20 is lowest priority, and allocation proportion 40% corresponding to bandwidth allocation priority 1, bandwidth allocation is excellent Allocation proportion corresponding to first level 2 is 35%, and allocation proportion corresponding to bandwidth allocation priority 3 is 15%, bandwidth allocation priority 4 Corresponding bandwidth allocation ratio is 10%, and allocation proportion corresponding to remaining bandwidth distribution priority is 0%.

S104：After to each target access network equipment distribution bandwidth, judge whether the video monitor distributes to obtain Bandwidth, if it is not, the video flowing that the video monitor is collected is stored into memory, the memory is the video monitor The storage device that the storage device or the video monitor that router carries in the video monitoring system of place carry.

Wherein, after bandwidth is distributed to each target access network equipment, the video monitoring in the video monitoring system is judged Whether device distributes to obtain bandwidth, when judging that the video monitor distributes to obtain bandwidth, illustrates current bandwidth abundance, does not occur Bandwidth bottleneck, the video flowing that can now collect video monitor are uploaded to high in the clouds；When judging that video monitor is unallocated When obtaining bandwidth, illustrate the higher equipment of more real-time demand (such as smart mobile phone, intelligent television etc.) occupied bandwidth be present, Then in order to ensure to be uploaded to the integrality of the video flowing in high in the clouds, the video flowing can be stored to the memory carried to router In, video monitor can also be notified to reduce frame per second and/or reduce resolution ratio to reduce the data volume for needing to upload.Wherein, should Memory is the storage device that router carries in video monitoring system where the video monitor；It is of course also possible to this is regarded Frequency stream is stored in the memory carried to the video monitor.

In addition, after the video flowing to be stored to the memory preset time carried to the video monitor, judging again should Whether video monitor distributes to obtain bandwidth, when judging that the video monitor distributes to obtain bandwidth, will store to video monitoring Video flowing in the memory that device carries is uploaded to high in the clouds.

In the embodiment of the present invention, it is determined that after multiple target access network equipments of current bandwidth to be allocated, according to each mesh The incremental order of time delay value required by tag splice log equipment, it may be determined that real-time of each target access network equipment to access network It is required that grade；By combining the principle of the assignment since limit priority, determine that the distribution of each target access network equipment is excellent Bandwidth allocation highest priority corresponding to the minimum target access network equipment of first level, i.e. time delay value, remaining target access network The bigger corresponding bandwidth allocation priority of time delay value of equipment is lower；Further, since in default first bandwidth distribution list Record has the bandwidth allocation ratio corresponding to each bandwidth allocation priority, then by the bandwidth allocation of each target access network equipment Priority is matched with each bandwidth allocation priority in first bandwidth distribution list, obtains corresponding bandwidth allocation ratio Example；According to bandwidth allocation ratio is obtained, bandwidth is distributed for each target access network equipment, realization is preferably that requirement of real-time is high Target access network equipment distributes bandwidth, improves Consumer's Experience；And after bandwidth is distributed for each target access network equipment, judge to regard Whether frequency monitor is distributed to obtain bandwidth, if distribution obtains bandwidth, the video flowing that video monitor is collected is uploaded to Cloud storage, otherwise, the video flowing that the video monitor is collected is stored into video monitoring system what router carried In storage device, or the storage device that carries of video monitor, that is, realize in the case of bandwidth resources deficiency, ensureing video On the premise of the video flowing of monitor uploads integrality and the Consumer's Experience in high in the clouds, in reasonable distribution miniature video monitoring system Bandwidth.

Alternatively,, should be according to each target access network in order to improve bandwidth allocation efficiency in a kind of specific implementation The incremental order of time delay value required by equipment, and the assignment principle since limit priority, determine that each target connects successively Before the bandwidth allocation priority of log equipment, this method can also include：

Determine current time information；

Judge whether the target recorded with presetting the second bandwidth distribution list presets access to each target access network equipment Net equipment matches completely, wherein, record has the default access network corresponding to each temporal information to set in second bandwidth distribution list It is standby, and the bandwidth allocation ratio corresponding to the default access network equipment, it is the current time that the target, which presets access network equipment, Default access network equipment corresponding to information；

It is each for this when judged result for when being, the bandwidth allocation ratio corresponding to access network equipment is preset based on the target Individual target access network equipment distributes bandwidth, and performs and should judge that this was regarded after to each target access network equipment distribution bandwidth The step of whether frequency monitor distributes to obtain bandwidth；

When judged result for it is no when, perform this according to incremental suitable of the time delay value required by each target access network equipment Sequence, and the assignment principle since limit priority, the bandwidth allocation priority of each target access network equipment is determined successively Step.

It is understood that in this kind of implementation, it is determined that the bandwidth allocation of each target access network equipment is preferential Before level, matched using default second bandwidth distribution list with each target access network equipment, wherein, second bandwidth point There is each temporal information with record in table, access network equipment, and default access network equipment are preset corresponding to each temporal information Corresponding bandwidth allocation ratio, therefore after current time information is determined, when finding current in the second bandwidth distribution list Between temporal information corresponding to information, and obtain the default access network equipment corresponding to the temporal information.
