Embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
According to Fig. 1, Fig. 2 and Fig. 3, the present invention is on the edge of stream media network buffer memory equipment, according to the attribute of the temperature of stream medium data content, freshness, file, file size etc. the stream medium data on the edge buffer memory equipment is managed automatically, deleted and upgrades, reach the Automatic Optimal of edge buffer memory.
Temperature and freshness for the stream medium data content: according to the user log files of edge buffer memory equipment, the attribute and the statistics of stream medium data file, determine the reasonable life period segment value △ T of temperature and freshness, select according to different media file properties or user, the optimum that obtains certain media file △ t at interval that fixes time, in the corresponding stream media data document creation, temperature and freshness are detected with fixed time interval △ t circulation.
Fig. 1 is the stream medium data content user visit trend graph of TV play class, and its longitudinal axis shows click data.As can be seen from this figure, files in stream media is from being put on the edge buffer memory equipment, and the number of users in the unit interval of visit this document will increase gradually, will reach peak value behind certain hour, and the calling party number will descend then.The Streaming Media temperature then is embodied as the number of users that uses this content in the unit interval, and big more this content that shows of temperature value is liked by the user more, thereby the value of preserving on the edge buffer memory is just big more.Clicks in the time period that the temperature value is undertaken by detection is determined divided by fixed time interval △ t, also can be described as clicking rate.And △ T can adopt probabilistic method to obtain, and to user clicking rate being tending towards 0 o'clock reasonable life period segment value at edge buffer memory equipment in beginning to create from media file is △ T.The value of fixed time interval △ t is to get different values according to different media file properties (as news, TV play, educational film, film), can offer the user and select, and also can adopt probabilistic method, obtains the optimum fixed time interval △ t of certain media file.
As shown in Figure 2, in the stream medium data document creation, △ t circulation detects temperature to fix time at interval, time at that time that detection is carried out and the difference of stream medium data document creation time are during greater than the reasonable life period segment value △ T of temperature and freshness, setting corresponding temperature value is 0, and this stream medium data file is deleted from the memory device of edge buffer memory.
Equally, for freshness, freshness has embodied the time value that the stream medium data file has existed on server, grade of freshness time at that time that to be reasonable life period segment value △ T carry out divided by detection and the difference in the stream medium data document creation, as shown in Figure 3, in the stream medium data document creation, with fixed time interval △ t circulation freshness is detected, time at that time that detection is carried out and the difference in the stream medium data document creation are during greater than the reasonable life period segment value △ T of temperature and freshness, setting corresponding fresh degree value is 0, and this stream medium data file is deleted from the memory device of edge buffer memory.
