Description
Technical field
This disclosure relates to the communications field, in particular to a kind of spatial cache dispatching method, device and system.
Background technique
CP (Content Provider, content provider) rents CDN (Content Delivery Network, content
Distribution network) when, CDN need to meet its KQI (Key Quality Indicator, Key Quality Indicator) index, wherein undercurrent rate
(ratio that need to obtain in real time to source station due to CDN node, which, not to be cached) is unusual important indicator.When undercurrent rate is below standard, CDN
It need to be compensated to CP.
The content of existing CDN node caching is determined according to the access temperature of node content, to institute inside CDN node
The content of storage is ranked up according to access to content temperature, node can timing sort subsequent content of temperature is deleted, to vacate
The new high temperature content of space storage.For big CP since the user of its service is more, temperature of the content temperature often than small CP is high, because
Content temperature of the content of this big CP often than small CP is higher, the colder content of the big CP also content temperature most hotter than small CP occurs
It is high.Since how much the content of caching determines the hit rate of content, small CP undercurrent rate is easy not reach under this mechanism
Mark.
To solve this problem, existing CDN is by way of dividing private resource for each CP, such as vCDN (Virtual
Content Delivery Network, virtual content distribution network), to solve to owe flow rate problem.Dividing private resource
Under mode, each CP can distribute the storage of fixed space, independently of each other, cannot share.Therefore, CDN node under this mechanism
The problem of reusability is not high, be easy to cause the wasting of resources.

It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, then in subsequent attached drawing does not need that it is further discussed.
Fig. 1 is the schematic diagram of disclosure spatial cache dispatching method one embodiment.Optionally, the method step of the present embodiment
Suddenly it can be executed by spatial cache dispatch server.Wherein:
Step 101, the undercurrent rate of each CP reported according to CDN node with predetermined period, judges whether there is undercurrent rate not
CP up to standard.
The undercurrent rate for each CP that CDN node is reported with predetermined period, so that spatial cache dispatch server can be slapped in time
Hold the undercurrent rate of each CP.
Step 102, there are undercurrent rate not CP up to standard, the CP temperature variable of specified CP is adjusted.
It optionally, can be according to the difference of target undercurrent rate and the current undercurrent rate of specified CP, to adjust the CP temperature of specified CP
Variable.
Step 103, the CP temperature variable of specified CP is handed down to CDN node, so that CDN node utilizes CP temperature variable pair
The content temperature of specified CP is adjusted, to dispatch the spatial cache of each CP.
Based on disclosure spatial cache dispatching method provided by the above embodiment, pass through owing according to CP each in CDN node
