Description

Content resource processing method, device, equipment and medium

Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, a device, and a medium for processing content resources.

Background

The cache server is an important component of the core network. In the core network, the cache server is mainly responsible for providing content resources, wherein the cache server stores a large amount of content resources, including: internet content resources, mobile multimedia content resources, game acceleration content resources, video loading content resources, and the like.

At present, a Cache server (Cache) serving as a service node in a core network adopts a centralized deployment mode, and is deployed in a larger city in multiple ways. When the user requests the content resource, the base station where the user is located applies for the content resource from the nearby cache server. When the content resource requested by the user does not exist in the cache server, or when the cache server fails, the cache server needs to continuously query the content resources in a plurality of other cache servers serving as service nodes one by one until the content resource requested by the user is queried.

Particularly, when the content resource requested by the user is stored in the cache server far away from the user, the content resource requested by the user needs to be sequentially inquired from the cache server closest to the user according to the distance between the cache server and the user and according to the sequence from near to far. The query mode causes that a user needs to go and return a longer query path when querying the content resource, thereby causing that the efficiency of querying the content resource is lower.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The embodiment of the invention provides a processing method, a processing device, processing equipment and a processing medium of content resources, which can be applied to a cache server cluster consisting of cache servers. Because the cache server cluster comprises a plurality of content resources, when the target content resource is queried, the identification information of the target content resource can be queried in the identification information of all the content resources contained in the cache server cluster. Each cache server in the cache server cluster stores identification information of a plurality of content resources, and a content resource routing table is arranged in each cache server. When the identification information of one of the target contents is not queried in a cache server, a next cache server may be determined with reference to the content resource routing table of the cache server, so as to continue querying the identification information of the target content resource in the next cache server.

The cache server in the embodiment of the present invention may be located in a network edge area, such as a small city, county, district, or county. In particular, the method is applicable to the construction and use of the fifth Generation mobile phone communication technology (5-Generation wireless telephone technology, 5G) network construction.

For better understanding of the present invention, a method, an apparatus, a device and a medium for processing a content resource according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be noted that these embodiments are not intended to limit the scope of the present disclosure.

Fig. 1 is a schematic flow chart illustrating a processing method of a content asset according to an embodiment of the present invention. As shown in fig. 1, the processing method 100 of the content resource in the present embodiment may include S110 to S140:

s110, determining a cache server to be queried in the cache server cluster.

The cache server cluster comprises a plurality of cache servers, and each cache server stores identification information of a plurality of content resources.

In S110, the plurality of cache servers may be divided into a cache server cluster according to the geographical location information of the cache servers. For example, all cache servers in a certain area are divided into a cache server cluster.

In some embodiments of the present invention, the identification information of the content resource in the cache server cluster is designed to be 48 bits. In other words, theoretically, the storage upper limit of the identification information of the content resource in one cache server cluster is 2⁴⁸Identification information of the individual content assets.

In some embodiments of the present invention, the identification information of the content asset in S110 is a number of the content asset. If all the cache servers in the cache server cluster are arranged in sequence, the number of the content resources stored by any cache server is smaller than the number of the content resources stored by the next cache server of any cache server.

As an example, if cache server N in a cluster of cache servers₁To N₂₀₀The cache server cluster comprises the number 1 of the content resource to the number 2 multiplied by 10 of the content resource¹⁴. Each cache server caches 10¹²The number of individual content assets. For example, the numbers 1 to 10 may be assigned¹²Is stored in N₁Will be numbered 10¹²+1 to 2X 10¹²Is stored in N₁Next cache server N of₂… …, numbered 199X 10¹²+1 to 2X 10¹⁴Is stored in N₂₀₀。

It should be noted that, in an actual implementation process, the order of magnitude of the cache servers in one cache server cluster is much higher than 200 in the example of the present embodiment.

In some embodiments of the present invention, the plurality of cache servers included in the cache server cluster are sequentially connected to form a closed loop.

In some embodiments, the closed loop may be a logically end-to-end loop.

As an example, fig. 2 is a schematic diagram of a closed loop in an example of an embodiment of the present invention. The cache server cluster comprises 200 cache servers N₁To N₂₀₀For example, as shown in FIG. 2, N₁To N₂₀₀Are connected in sequence according to the size of the sequence number, and the first cache server N₁With the last cache server N₂₀₀Connected to form a closed logic loop.

In other words, in the clockwise direction, cache server N on the logical ring₁Is N₂Cache server N₁Last buffer of is N₂₀₀. Cache server N₂₀₀Is N₁Cache server N₂₀₀Last cache server of is N₁₉₉。

For convenience of description, the following embodiments of the present invention take an example in which a plurality of cache servers included in a cache server cluster are logically connected in sequence to form a closed loop, that is, a next cache server of a last cache server in the cache server cluster is a first cache server in the cache server cluster. And the last cache server of the first cache server in the cache server cluster is the last cache server in the cache server cluster.

It should be noted that the closed loop formed by the plurality of servers is a logically closed loop, and there is no limitation on whether physical connection is required between adjacent cache servers, and the geographical location relationship between the plurality of cache servers.

In some embodiments of the invention, the identification information of the content asset comprises a number of the content asset.

In some embodiments of the present invention, if a query request of a target content resource of a user is received, a cache server closest to the user may be determined in a cache server cluster according to geographic location information of the user, and the determined cache server is used as an initial cache server to be queried.

S120, judging whether the cache server to be inquired contains the identification information of the content resource which is the same as the identification information of the target content resource.

The execution subject of S120 may be a cache server to be queried or a processor of the entire cache server cluster.

In some embodiments of the invention, the target content resource is a content resource requested to be queried by a user through a query request of the target content resource.

In some embodiments of the invention, the identification information of the target content asset comprises a number of the target content asset.

In some embodiments of the present invention, the specific implementation of S120 may include:

and judging whether the cache server contains the number of the content resource which is the same as the number of the target content resource.

For convenience of explanation, the following sections of the embodiments of the present invention will explain identification information of a target content resource and identification information of a content resource, respectively, by taking the number of the target content resource and the number of the content resource as examples.

S130, if the cache server to be queried contains the identification information of the content resource which is the same as the identification information of the target content resource, determining to query the target content resource in the cache server to be queried.

As an example, if the target content resource is numbered 10¹²+5×10⁸Buffer N to be queried₂Number 10 containing content asset¹²+1 to 2X 10¹². Since the buffer N to be queried₂Number 10 of the content asset involved¹²+5×10⁸Number 10 with target content resource¹²+5×10⁸The same is true. Determining whether a cache server N is to be queried₂Querying the target content resource. In other words, the number is 10¹²+5×10⁸Target content resource caching in a cache server N to be queried₂In (1).

In the embodiment of the present invention, in addition to the target content resource that can be queried in the cache server to be queried in S130, there is also a case that the target content resource cannot be queried in the cache server to be queried, specifically, as shown in S140.

S140, if the cache server to be queried does not contain the identification information of the content resource which is the same as the identification information of the target content resource, determining the cache server corresponding to the identification information of the target reference content resource in the content resource routing table of the cache to be queried as a new cache server to be queried, judging whether the new cache server to be queried contains the identification information of the target content resource until the new cache server to be queried contains the identification information of the target content resource, and determining to query the target content resource in the cache server to be queried.

As an example, if 200 cache servers are included in the cache server, the content resources need to be queried one by one in the 200 cache servers in the prior art.

By using the technical contents in S110 to S140 in the embodiment of the present invention, if the 8 th cache server is used as the cache server to be queried, the 44 th cache server may be determined as the second cache server to be queried directly according to the content resource routing table of the 8 th cache server. And then, determining the 49 th cache server as a third cache server to be queried by using the content resource routing table of the 44 th cache server. And finally, determining that the 50 th cache server is the fourth cache server to be queried by using the content resource routing table of the 49 th cache server, and if the target content resource is queried in the 50 th cache server, finishing the query only by 4 cache servers.

According to the content resource processing method in the embodiment of the invention, when the cache server to be queried does not contain the identification information of the target content resource, the target content resource can be queried in the new cache server to be queried. And the new cache server to be inquired is the cache server corresponding to the identification information of the target reference resource in the content resource routing table. Because the identification information of the target reference content resource can be used as the reference information for selecting a new cache server to be queried, and the correlation between the identification information of the target reference content resource and the identification information of the target content resource is relatively high, the cache server corresponding to the identification information of the target reference content resource is used as the next cache server to be queried, so that the number of cache servers to be queried is reduced, and the speed of querying the target content resource is increased. Therefore, by the content resource processing method in the embodiment of the invention, the query efficiency of the content resource is improved.

As an example, if the target content resource is numbered 2 × 10¹²+5×10⁸Buffer N to be queried₂Number 10 containing content asset¹²+1 to 2X 10¹². Since the buffer N to be queried₂Number 2 x 10 of the target content resource is not included in¹²+5×10⁸The number of the same content asset. Determining whether a cache server N is to be queried₂The target content resource is not queried.

In some embodiments of the present invention, the identification information of the reference content resource is identification information of a plurality of content resources selected from the identification information of the content resources included in the caching server cluster and used for reference.

As an example, the identification information of the reference content resource included in the content resource routing table of a cache server may be selected from identification information of content resources included in other cache servers except for the cache server.

In some embodiments of the present invention, the content resource routing table includes a plurality of correspondences between identification information of reference content resources and the cache server. The correlation degrees of the identification information of the multiple reference content resources and the identification information of the target content resource can be respectively determined, the identification information of the reference content resource with the maximum correlation degree with the identification information of the target content resource is used as the identification information of the target reference content resource, and the cache server corresponding to the identification information of the target reference content resource is determined as a new cache server to be queried.

In some embodiments, if the labels of the plurality of reference content resources in the content resource routing table of the cache server to be queried are sequentially arranged from small to large. The number of a reference content resource is not less than the number of the target content resource, the number of the next reference content resource of the reference content resource is greater than the number of the target content resource, and the correlation degree between the number of the reference content resource and the number of the target content resource is the largest.

As an example, the content resource routing table in the caching service to be queried is shown in table 1. The content resource routing table records the correspondence between the reference content resource reference label a and the cache server a, the correspondence between the reference content resource reference label B and the cache server B, and the correspondence between the reference content resource reference label C and the cache server C.

TABLE 1

Numbering of reference content resources	Cache server
		a	A
b	B
		c	C

As shown in table 2, when the value range of the number of the target content resource is between [ a, b), the number of the target content resource is not less than the number a of the reference content resource and is less than the number b of the next reference content resource, and the correlation between the number a of the reference content resource and the target content resource is the largest. Accordingly, the number a of the reference content resource is the number of the target reference content resource.

When the value range of the number of the target content resource is between [ b, c), the number of the target content resource is not less than the number b of the reference content resource, and the number c of the next reference content resource is greater than the number of the target content resource, at this time, the correlation degree between the number b of the reference content resource and the target content resource is the maximum. Accordingly, the number b of the reference content resource is the number of the target reference content resource.

When the value range of the number of the target content resource is between [ c, d ] < U [1, a), the number of the target content resource is not less than the number c of the reference content resource, and the label a of the next reference content resource is regarded as being greater than the number of the target content resource, at this time, the correlation degree between the number c of the reference content resource and the target content resource is the maximum. Accordingly, the number c of the reference content resource is the number of the target reference content resource.

It should be noted that, if the cache server cluster includes d content resources in total, when the value range of the number of the target content resource is between [ c, d ], [ u [1, a ], the number of the target content resource is regarded as not less than the number c of the reference content resource, and the number a of the next reference content resource is regarded as greater than the number of the target content resource, and then the correlation between the number c of the reference content resource and the target content resource is the largest. Accordingly, the number c of the reference content resource is the number of the target reference content resource. Wherein a, b, c and d are positive integers, and a < b < c < d.

TABLE 2

In some embodiments of the present invention, in order to further improve the query efficiency of the content resource, the numbers of the plurality of reference content resources in the content resource routing table of each cache server are sequentially arranged from small to large. Wherein, the difference of the numbers of all the two adjacent reference content resources forms an equal ratio sequence. For example, the common ratio of the series of equal ratios is 2.

In some embodiments, the reference content resource in the content resource routing table in the cache server has a number that is the sum of a fixed value and a power of 2. Specifically, the fixed value may be the maximum number of the content resource cached in the cache server. Namely, the number of the reference content resource of the content resource routing table in the cache server is the sum of the maximum number of the content resource cached in the cache server and the power of 2. For example, the number of the ith reference content resource is the sum of the maximum number of the content resource cached in the cache server and the power of the (i-1) th power of 2. Wherein i is a positive integer. It should be noted that, when the number of the reference content resource in the content resource routing table is the sum of a fixed value and the power of 2, the power of 2 value corresponding to the maximum number of the reference content resource should be smaller than the upper limit of the cache of the identification information of the content resource in the cache server cluster. For example, if the caching upper limit of the identification information of the content resource in the cache server cluster is 2⁴⁸Maximum number of reference content resource is f +2⁴⁷，2⁴⁷<2⁴⁸. Where f is a fixed value.

It should be noted that, in order to reduce the storage pressure of the content resource routing table on the cache server and increase the query speed, the content resource routing table may be a part of the above content routing resource table. For example, the number of the 1 st reference content resource is the sum of the maximum number of the content resource cached in the cache server and the k-th power of 2.

Wherein k is a positive integer greater than 1. And the value of the power of k of 2 is smaller than the number of numbers of content resources contained in one cache server. For example, if each cache server includes 10¹²The number of each content resource is such that the value of the power k of 2 is less than 10¹²The number of (2).

As an example, if the caching upper limit of the identification information of the content resource in the caching server cluster is 2⁴⁸The cache server cluster comprises 10¹⁴Number of individual content assets 1 to 10¹⁴The ratio is 2. Cache server N₁The number of the cached content resources is 1 to 10¹²Cache server N₂Number of cached content asset 10¹²+1 to 2X 10¹²… …, Server N₂₀₀The number of the cached content resources is 199 × 10¹²+1 to 2X 10¹⁴。

Cache server N₈The content resource routing table of (1) is shown in table 3. Cache server N₈Has a maximum number of 8 x 10 of cached content resources¹². The content resource routing table comprises the serial numbers of 48 reference content resources, and the power of the common ratio value of the serial numbers of the 48 th reference content resource is 2⁴⁷Less than 2⁴⁸. The reference content resource number is cache server N₈Maximum number of cached content resources of 8 x 10¹²The product with the power of 2. Table 3 the powers of 2 are 0 to 2, 1 to 2, … …, and 47 to 2, respectively, as viewed from above.

TABLE 3

Table 4 shows how a new cache server to be queried is selected. As shown in Table 4, when the number of the target content asset is 50 × 10¹²Of time, target content resourcesThe number is in the range of [8 × 10 ]¹²+2⁴⁵，8×10¹²+2⁴⁶) In this case, the number of the target reference content resource can be determined to be 8 × 10 according to the content resource routing table of table 3¹²+2⁴⁵The cache server corresponding to the number of the target reference content resource is N₄₄At this time, N may be₄₄As a new cache server to be queried.

TABLE 4

When N is present₄₄As a new cache server to be queried, N₄₄The content resource routing table in (1) is shown in table 5. Cache server N₄₄Has a maximum number of 44 x 10 of cached content resources¹². Since 50 is multiplied by 10¹²In the [ 44X 10 ]¹²+2⁴²，44×10¹²+2⁴³) In accordance with N₄₄Determines the number of the target content resource to be 50 x 10¹²Number 44 x 10 of the target reference content resource of (2)¹²+2⁴²Accordingly, the number of content resources 44 × 10 will be referenced¹²+2⁴²Corresponding cache server N₄₄And determining as a new cache server to be queried.
