Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, for a kind of flow diagram of video content distribution scheduling method provided in an embodiment of the present invention, it should
Method can include：
Step S101：Receive the status data of video content distribution data and Edge Server.
Wherein, the status data of Edge Server can include：Edge Server receive video content request number,
It responds the number of video content access request, respond the handling capacity of time of video content access request, unit interval, broadcast
Code check of video etc..
Step S102：Status data according to video content data and Edge Server determines QoS parameter.
Wherein, QoS parameter can include：The availability parameters of video content, the response parameter of video request,
The continuity parameter of video playing and video playing quality parameter.
Specifically, the availability of video content, refers to that user can normally access video content that is legal and having authorized.
If user cannot normally access content that is legal and having authorized, then there have been problems for the availability of video content.It is logical
In the case of often, the mandate to video content is generally not to be performed in VCDN systems, therefore, by the video after routing
It is all legal to hold access request.In this way, in VCDN systems, side can be focused on to the measurement of the availability of video content
Whether edge server being capable of all video content access request of complete response.In the present embodiment, the availability of video content
Parameter can respond the number of video content access request whithin a period of time with Edge Server and receive video content visit
The ratio of the number of request is asked to measure, is denoted as QoS_A.
Specifically, the response of video request, refers to that Edge Server responds the time of video content access request.Edge
Server responds the time of video content access request, both includes the time of authentication, also includes the time of request routing and plug-flow,
It even there may also be the time for obtaining key descrambling video flowing.Since the processing time of request routing and plug-flow is in VCDN system models
In enclosing, therefore, in the present embodiment, the processing time of request routing and plug-flow is only considered.In a kind of possible realization method,
Initial time stamp can be stamped for it when routing server receives video content access request, be rung in Edge Server
Video content access request is answered to stamp deadline stamp again later.Assuming that receive video content access request from routing server
Time to Edge Server response video content access request is request-access time, then can use in a period of time and own
Response parameter of the average value of request-access time as the video request of VCDN systems, is denoted as QoS_R.
Specifically, the continuity of video playing, refers to client during video content is received with the presence or absence of broadcasting
The situation of interruption.The most direct mode of continuity of measurement video playing is to receive data in client statistical unit time internal cause
The number that video playing is not enough caused to suspend or buffer.There is compulsory requirement to client in view of above-mentioned metric form, together
When can also increase the difficulty of collection of statistical data, in the present embodiment, using the handling capacity and phase of monitoring Edge Server plug-flow
The code check of video content is answered to carry out indirect geo-statistic and plays interruption times, that is, in case of (such as 1 second or 10 seconds) in the unit interval
Handling capacity be less than the situation of code check, then it is assumed that be to be interrupted, all video contents in a period of time can be used to visit
It asks continuity parameter of the average value as video playing of the interruption times of request, is denoted as QoS_C.
Video playing quality can be assessed with the code check for delivering video.The audio content matter of high code check under normal conditions
Amount is just high.But for different terminal equipment, the meaning of video quality is different.For example, the mobile end for the small screen
For end, the code check of 1Mbps or so can reach very good video quality, and for the TV of large screen,
The code check of more than 6Mbps is likely to reach good video quality.It, can be by video playing quality division etc. for the ease of assessment
Grade, for example, super clear, high definition, SD, smoothness, and same grade is different for different terminal device standards.In the present embodiment
In, using the percentage of grade each in preset time as video playing quality parameter, it is denoted as QoS_Q.
Step S103：Determine operation cost parameter.
Wherein, operation cost parameter includes system acquisition cost parameter Cost_P, operation maintenance cost parameter Cost_M, band
Wide cost parameter Cost_B and third party's service cost parameter Cost_O.
Specifically, purchase cost mainly includes server cost and network equipment cost.Operation maintenance cost includes manpower
Cost and computer room cost, the degree of automation is higher, system is more healthy and stronger, and human cost is lower, computer room cost then with VCDN systems
Framework it is related with configuration, be mainly reflected in space cost and power cost.Third party's service cost for third party's trustship some
The cost of service.
Step S104：Service quality and operation are established by QoS parameter and operation cost parameter based on system resource
The mapping relations of cost.
Specifically, since service quality is related with system resource, and system resource is related with operation cost, it therefore, can
QoS parameter is associated with system resource, by system resource and operation cost parameter association, and then will by system resource
QoS parameter and operation cost parameter association establish the mapping relations of service quality and operation cost.
Wherein, system resource can include：The oncurrent processing ability of server and the capacity of bandwidth, the storage energy of server
Power, handling capacity of server etc..
Service quality is related with system resource to be embodied in, and the availability of video content depends on the concurrent processing energy of server
The capacity of power and bandwidth, the oncurrent processing ability of server is stronger and the capacity of bandwidth is more sufficient, the availability of video content
It is higher.The response of video content depends on the distribution situation of video content, and the distribution of video content actually reflects pair
The requirement of server storage ability, such as server storage capacity etc..The continuity of video content depends on handling up for server
Ability, handling capacity are actually a kind of integration capability, are by the distribution situation of content, server concurrent capability and bandwidth capacity
It codetermines.Video content quality is similarly dependent on the handling capacity of server.
System resource is related with operation cost to be embodied in, the oncurrent processing ability of server determine the buying of system into
This, bandwidth capacity determines bandwidth cost, and storage capacity determines system acquisition cost.And third party's service cost mainly by
What these three system resources codetermined（Such as cloud service, without purchasing equipment, without O＆M, even without bandwidth is rented, all
To be cloud service provider accomplish fluently packet by these system resources provides together）.Operation maintenance cost is more special, can be divided into two
Point, a part depends directly on purchase cost, and substantially linear with purchase cost, and another part is then manually to tie up
Protect cost, substantially a constant m.Therefore, operation maintenance cost can be expressed as Cost_M=p × Cost_P+m.
Based on above-mentioned analysis, the mapping relations of service quality and operation cost can be established, by service quality mapping to fortune
Seek cost：
QC1：N×QoS_A→a1×Cost_P+a2×Cost_B+a3×Cost_O
QC2：N×QoS_R→r1×Cost_P+Cost_M+r2×Cost_O
=(r1+p)×Cost_P+r3×Cost_O+m
QC3：N×QoS_C→c1×Cost_P+Cost_M+c2×Cost_B+c3×Cost_O
=(c1+p)×Cost_P+c2×Cost_B+c3×Cost_O+m
QC4：N×QoS_Q→q1×Cost_P+Cost_M+q2×Cost_B+q3×Cost_O
=(q1+p)×Cost_P+q2×Cost_B+q3×Cost_O+m
Wherein, N represent can concurrent services number of request.P and m can be determined completely by the O＆M empirical data of history,
Constant can be considered as.Under stable operation mode, each coefficient of QC1 to QC4 will not change substantially.
Each coefficient of QC1 to QC4 can calculate as follows：
(1) in the case where a basic system is formed and is configured, the value of each QoS parameter is monitored.
(2) increase video content request, in the range of power system capacity can be born, with the Extension of service of userbase
Quality will not decline, and inflection point can occur until reaching critical point service quality, record service quality value and various aspects at inflection point
System cost value.
(3) a small amount of cost upgrade-system is put into, ensures that service quality goes back up to initial level, is then transferred to step (2),
Until collecting enough data (at least 3 groups of data).
(4) data of collection are substituted into QC1 to QC4, calculates linear equation and obtain each coefficient.
It should be noted that the greatest extent may be used by the resource that above formula and calculating process can be analyzed as how most saved
Maximum service capacity (N × QoS_Q), referred to as base cost and service relationship between quality can be met.
It should be noted that the effect of QC1 to QC4 is mainly reflected in：In QC1 to QC4 relational expressions, the larger item of coefficient,
Illustrate that smaller cost input with regard to that can bring the promotion of obvious service ability, therefore, faces user in service provider
During the problem of popularization, service quality declines, it may be considered that first will be in the cost of resource input to which part.Base cost
It illustrates that a rational proportion of the cost input of different aspect is how many with service relationship between quality, has to practical operation important
Meaning.It is quick to find the cost input aspect being wasted or the aspect required supplementation with.The optimization of guidance content distribution scheduling.
Step S105：Mapping relations according to the marketing strategy, service quality and operation cost determine video content
Distribution scheduling strategy, wherein, distribution scheduling strategy is used to indicate which video content is distributed to which service node, and is replaced
Which video content.
Referring to Fig. 2, in video content distribution scheduling method provided in an embodiment of the present invention, according to marketing plan
Slightly, the mapping relations of service quality and operation cost determine a kind of realization method of the distribution scheduling strategy of video content to be distributed
Flow diagram, can include：
Step S201：Video content to be pushed and corresponding video content to be pushed are determined from the marketing strategy
Destination service node, can meet the requirement of video content to be pushed to cost according to destination service node and determine to wait to push
The distribution scheduling strategy of video content.
Further, the requirement of video content to be pushed to cost can be met according to destination service node to determine to wait to push away
The distribution scheduling strategy for sending video content is specially：When destination service node disclosure satisfy that video content to be pushed to cost
It is required that when, determine the distribution scheduling strategy of video content to be pushed for will be to be pushed video distribution to destination service node；
When destination service node is it is impossible to meet wait requirement of the video content pushed to cost, the video for needing most and being replaced is found out
Content, the distribution scheduling strategy for determining video content to be pushed are to need most what is be replaced with video content replacement to be pushed
Video content.
Step S202：It is assessed in video by the mapping relations of QoS parameter and service quality and operation cost
The service quality of appearance.
When carrying out video content distribution scheduling, what is considered is the distribution scheduling of video content to service quality and operation
The influence of cost.The distribution scheduling of video content can be conceptualized as triple (Cnew, Node, Cold), i.e. video content CnewQuilt
It is distributed on service node Node, and replaces video content Cold.If video content Cold=0, then mean that without replacing
And it is only to increase video content.What video content distribution directly affected is server storage capacity, is adopted so as to influence system
Purchase cost Cost_P or third party's service cost Cost_O；Influence to the service quality of service node Node is then for video
Content CnewService quality promotion and for video content ColdService quality decline.
It is understood that in practical applications, if the memory capacity of service node still has remaining or old video
Content is replaced, then any cost can't be increased, if the degree that the old video content being replaced is concerned is very low, that
Any influence will not be generated to overall quality of service.Accordingly, it is determined that during video content distribution scheduling strategy, need these
Factor is also contemplated for into.
In the present embodiment, with QoS_Content represent with the relevant overall quality of service of the distribution of all video contents,
With QoS_Content_C represent with the relevant stand-alone service quality of the distribution of content C, there are following relationships therebetween：
QoS_Content=QoS_Content_C1+QoS_Content_C2+…+QoS_Content_Cn=α1×QoS_
Content+α2×QoS_Content+…+αn×QoS_Content (1)
Wherein, factor alpha represents the influence coefficient of a certain content, value between zero and one, it is all α's and be 1.If certain
One video content is not watched completely, then its influence coefficient is exactly 0；If the video content by extensive program request, that
Its influence coefficient is just close to 1.Therefore, the computational methods of α are exactly asking for a certain video content in statistics a period of time
Ask number and the ratio of total number of request.
Overall quality of service is represented with QoS_Total：QoS_Total=N × (a × QoS_A, r × QoS_R, c × QoS_C,
Q × QoS_Q), i.e., overall quality of service is a four-tuple, and a, r, c, q therein represent the coefficient of each component, N, that is, concurrent
Handle the quantity of request.For different systems, component coefficient is a set of constant, can by test and calculate linear equation come
It obtains（Similar to the calculating to QC1 to QC4）.Since the present embodiment is not concerned with the absolute value of service quality, can by a, r,
C, q is set as 1.
Influence of the distribution of video content to QoS_Total, essentially consists in QoS_R and QoS_C components.Therefore, Ke Yiding
Adopted QoS_Content=N × (r ' × QoS_R, c ' × QoS_C), ibid, by r ' and c ' is set as 1, can thus use practical
The service quality that can be monitored assesses the service quality of video content.The only of single video content can be navigated to by formula (1)
Vertical service quality, i.e. QoS_Content_Ci=α i × N × (r ' × QoS_R, c ' × QoS_C).Further, by QC2 and
QC3 can assess the service quality of video content with operation cost.
Step S203：With reference to the distribution scheduling strategy for treating pushing video content, pass through the Service Quality of the video content of assessment
Amount determines the distribution scheduling strategy of video content.
After the distribution scheduling strategy of video content is determined, the flow of video content distribution scheduling method is returned：
Step S106：The distribution scheduling strategy of video content is sent to source server, so that source server is based on video
The distribution scheduling strategy of content is distributed video content scheduling.
