Detailed description of the invention
For making those skilled in the art be more fully understood that technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
The present invention is described in further detail by formula.
Embodiment 1:
Refer to Fig. 1, the present embodiment provides a kind of video service quality index to generate method, including:
Step 101, video service quality index generating means inquires the number of correspondence according to the video request that terminal sends
According to bag.
Step 101 specifically includes:
Step 1011, video service quality index generating means receives the video request that terminal sends.
It is to say, user is regarded to the transmission of video service quality index generating means by terminal according to the wish of oneself
Frequency request, it is to be understood that the corresponding video request of each video.For OTT video traffic, operator carries
For network, video provider provides Video service, and such as, video provider is A, then video request is provide A a certain
The request of video.
Step 1012, video service quality index generating means inquires the packet of correspondence according to video request.
In other words, video service quality index generating means i.e. can determine that according to video request this video request is corresponding
Video, then inquire the packet corresponding with this video.
Step 102, video service quality index generating means sends data packets to terminal.
I.e. video service quality index generating means sends data packets to terminal, should by terminal viewing for user
Video.It is understood that user simply watches video, without this packet is carried out any analysis.
Step 103, packet is detected by video service quality index generating means, generates basic network index.
It should be noted that packet includes that packet is entered by a lot of information, video service quality index generating means
Row detection actually extracts useful information in packet, i.e. basic network index；Regard conversely, for being not used in evaluation
Frequently the index of quality of service is not extracted.
Step 104, basic network index is sent to Data Analysis Platform by video service quality index generating means, for
Data Analysis Platform generates video service quality index according to basic network index.
Step 104 specifically includes:
Step 1041, basic network index is sent to Data Analysis Platform by video service quality index generating means.

Frequently quality of service index includes: video page shows the time first.
Step 1042 includes: webpage entire packet end of transmission time deducts web-page requests and sends time generation video
The page shows the time first.I.e. [video page shows the time first]=[webpage entire packet end of transmission time]-[webpage
Request sends the time].
Wherein, basic network index includes: successfully play quantity and the quantity of all videos viewing request of video；Video
Quality of service index includes: video playback success rate.
Step 1042 includes: the business of the quantity quantity successfully playing video asked divided by all videos viewing is multiplied by
100% generates video playback success rate.I.e. [video playback success rate]=([successfully playing the quantity of video] ÷ [all videos
The quantity of viewing request]) × 100%.
Wherein, basic network index includes: TCP sets up time, dns resolution time delay, cache file size and cache file
Loading speed；Video service quality index includes: user waits video reproduction time first.
Step 1042 includes: set up by TCP time, dns resolution time delay and service request time delay and plus cache file
Size generates user divided by the business of cache file loading speed and waits video reproduction time first.I.e. [user waits that video is first
Reproduction time]=([TCP sets up the time]+[dns resolution time delay]+[service request time delay])+([cache file size] ÷ is [slow
Deposit file loading speed]).
Wherein, basic network index includes: video file size and video duration；Video service quality index includes: regard
Frequently definition.
Step 1042 includes: video file size is multiplied by 8 long-pending divided by video duration.I.e. [video definition]=[depending on
Frequency file size] × 8 ÷ [video duration].
Wherein, basic network index includes: receive the time of video file data bag for the first time；Video service quality index
Including: video file starts the load time.
Step 1042 includes: be equal to video file when starting to load the time receiving for the first time video file data bag
Between.I.e. [video file starts the load time]=[receiving the time of video file data bag for the first time].
Wherein, basic network index includes: video loading speed and video duration；Video service quality index includes: regard
The average loading speed of frequency.
Step 1042 includes: divided by video duration, video loading speed is generated the average loading speed of video.I.e. [video is put down
All loading speeds]=[video loading speed] ÷ [video duration].
Wherein, basic network index includes: current Streaming Media bag download, playback rate and currently playing duration；Video
Quality of service index includes: video playback card pauses number of times.
Step 1042 includes: by current Streaming Media bag download less than playback rate and currently playing duration product time
Number generates video playback cards and pauses number of times.I.e. [play speed as [video playback card pause number of times]=[current Streaming Media bag download] ＜
Rate] × [currently playing duration] time, be denoted as primary video play card, wherein, [playback rate] pass through video format and file
Form obtains.
