The executive agent of above steps can be a content routing server in the content distributing network CDN system, and promptly the method that provides of present embodiment can be realized by content routing server in the content distributing network CDN system.
The method of the distributed content management that the embodiment of the invention provides, by the corresponding relation that prestores between classifying content sign and the storage site, make the content routing server to obtain identifying corresponding storage site by this mapping ruler with classifying content, and the address information of this storage site returned to the addressing client, so that the addressing client finds this storage site to carry out the injection or the download of content; Because the classifying content that content supplier can be provided is stored in the storage site corresponding with the classifying content sign, thereby refinement and then can improve the effective rate of utilization of memory space to the management of each storage site memory space; In addition,, can save the memory space of storage site to a certain extent like this, so that satisfy to the required memory space of newly-increased CP or to the autgmentability demand of the memory space of existing CP because classifying content is stored in the part storage site.
Embodiment one:
To provide a specific embodiment at the method for distributed content management below.
The distributed content management method that present embodiment provides, need in the content routing server, mapping ruler to be set in advance, set up corresponding relation between classifying content sign and the storage site according to described mapping ruler, and described corresponding relation is stored in the content routing server.
Described mapping ruler can be a kind of algorithm, and this algorithm is corresponding with storage site with the classifying content sign, and the corresponding relation between classifying content sign and the storage site can be embodied in mapping table.Below, be that the distributed content management method that example comes present embodiment is provided is set forth with a mapping table, but in concrete implementation procedure, can realize the classifying content sign that writes down in this mapping table and the corresponding relation between the storage site by algorithm.
Because it is a variety of that the classifying content situation that provides at content supplier has, so the structure of this mapping table is not unique.In this specific embodiment, will provide a kind of scheme that mapping table is set as a reference, elaborate the method for described distributed content management,, similar for other with the method for present embodiment with the diacritical distributed content management method of mapping table, do not give unnecessary details so do not add.
Consider actual demand, can implement different storage policies at the targeted customer of zones of different, in this specific embodiment, provide a kind of mapping table, reference table 1 in order to make content supplier.Generate the scheme of this mapping table, may further comprise the steps:
S1, set up the corresponding relation between classifying content sign and the storage site.
Wherein, the described classifying content sign classification domain name that can be different content provider set at the storage site of zones of different.
For example, there is a CP1 of content supplier to set sorting field www.cp1.us by name at the storage site of the U.S.; At this moment, with this classification domain name the storage site of corresponding relation being arranged is all storage site of the U.S., is targeted customer's storage site partly or completely with the user in the U.S. promptly, as storage site such as San Francisco, New York.
Similarly, the CP1 of this content supplier sets sorting field www.cp1.cn by name at the storage site of China; Have the storage site of corresponding relation with this classification domain name this moment is all storage site of China, is targeted customer's storage site partly or completely with the user in China promptly, as storage site such as Beijing, Shanghai.
And for example, there is a CP2 of content supplier to set sorting field www.cp2.com by name at the storage site in the whole world; Have the storage site of corresponding relation with this classification domain name this moment is whole world storage site partly or completely, comprises the storage site partly or completely of All Countries such as the U.S., China.
S2, generate a mapping table, see Table 1 according to corresponding relation described in the step S1.
Table 1
The mapping table that is generated among S3, the preservation step S2.
Corresponding relation in the above-mentioned mapping table between shown classifying content sign and the storage site can utilize the mapping ruler of algorithm or other modes to set up, and described corresponding relation is stored in the content routing server; Above-mentioned mapping table directly can certainly be stored in the content routing server, so that the content routing server finds the address information of corresponding storage site with it according to the classifying content sign that receives, content service provider just can be stored in classifying content in the different storage site like this.
In addition, described classifying content sign can also add the path at the pairing domain name of the storage site of zones of different for content supplier.At this scheme, embodiment provides mapping table as shown in table 2.
Table 2
| The classifying content sign | Storage site |
| www.cp1.com/us | The U.S.: website 1 (San Francisco), website 2 (New York) etc. |
| www.cp1.com/cn | China: website 3 (Beijing), website 4 (Shanghai) etc. |
Wherein, the CP1 of content supplier in the above-mentioned example can add path www.cp1.com/us for domain name at the pairing classifying content sign of the storage site of the U.S..
Because for the content routing server, the variation of classifying content sign, just cause the pro forma variation of mapping table, but do not influence the corresponding relation between classifying content sign and storage site, so is that domain name adds distributed content management method that this mode of path carries out and do not add and give unnecessary details after this to the content class indication, the distributed content management method that its detailed process can the reference content class indication be carried out for classification domain name mode.Certainly, in the practical application, the classifying content sign that the mapping table in table 1 and the table 2 can be set up if necessary and the corresponding relation between the storage site all are kept in the content routing server.
Need to prove, be not limited to form in the above-mentioned mapping table for the setting of classifying content sign.Above-mentioned mapping table just illustrates between classifying content sign and the storage site as an example and has corresponding relation.
Below, according to the corresponding relation that the mapping table in the table 1 is set up, the content routing server can realize content supplier is provided the distributed content management of content by carrying out Route Selection at zones of different, the specific implementation process is as follows:
At first, inject this process of content at content supplier to storage site, as shown in Figure 2, the distributed content management method that present embodiment provides specifically may further comprise the steps:
201, the classifying content sign of content routing server received content client transmission.
Wherein, content client can be ftp client in this instantiation.
In this instantiation,, then by ftp client the classifying content sign www.cp1.us of this part content is sent to the content routing server by the CP1 of this content supplier if the CP1 of content service provider has partial content just to the user's issue in the U.S..
202, the content routing server obtains the corresponding storage site of described classifying content sign according to the classifying content that prestores sign with corresponding relation between the storage site.
In this instantiation, the corresponding relation that is pre-stored in the content routing server can be set up according to the mapping ruler in the table 1.Finding the pairing storage site of classifying content sign www.cp1.us according to the mapping table of table 1 is all storage site of the U.S..
203, the content routing server returns to described content client with the address information of described storage site.
Wherein, described address information can be the IP address.
In this instantiation, according to step 202 as can be known the CP1 of content supplier to inject content to the storage site of the U.S., in this step, the content routing server returns to ftp client with one or more IP address of the storage site of the U.S..
Afterwards, ftp client can provide the CP1 of content supplier at the user in the U.S. content, the IP address of returning according to content routing server in the step 203 is stored in the storage site of described IP address correspondence.
Utilize above-mentioned distributed content management method, set up the corresponding relation between classifying content sign and the storage site, make content supplier can according to the difference of classifying content sign with content release in the storage site of part, thereby saved memory space; And utilization the method, content supplier can also issue different contents at the targeted customer of zones of different, promptly realize content distributed district management, help content supplier like this and implement different content distributed strategies at the targeted customer of zones of different.
Below, download this process of content at the user from storage site, as shown in Figure 3, the distributed content management method that present embodiment provides specifically may further comprise the steps:
Need to prove, be Edge Server in addressing client described in the CDN system; Certainly, in non-CDN system, described addressing client then can be other servers that can be used for addressing.Below, being that example is set forth in the CDN system.
301, the content routing server receives the classifying content sign that Edge Server sends.
Wherein, in this specific embodiment at the CDN system, when the user when the content of Edge Server request is miss, Edge Server sends the classifying content sign to the content routing server.
In this instantiation, suppose to have a user in the U.S. to wish to download the content that the CP1 of content supplier provides, then the user sends content requests www.cp1.com to Edge Server, at this moment, if the content that this user did not ask in the buffer memory of Edge Server, then Edge Server can be judged this user in the U.S., draws classifying content sign www.cp1.us then, and this classifying content sign is sent to the content routing server; Certainly the user also can directly be the classifying content sign to the content requests that Edge Server sends, and at this moment, Edge Server need not conversion through judging, then this classifying content sign is sent to the content routing server.
302, the content routing server obtains the corresponding storage site of described classifying content sign according to the classifying content that prestores sign with corresponding relation between the storage site.
In this instantiation, can find the pairing storage site of classifying content sign www.cp1.us according to the mapping table of table 1 is the storage site of the U.S..
303, the content routing server returns to described Edge Server with the address information of described storage site.
Wherein, described address information can be the IP address.
In this instantiation, can obtain this U.S. user according to step 302 and wish that downloaded contents is kept in the storage site of the U.S., then the content routing server selects one or more available IP addresses to be back to Edge Server from the IP address of the storage site of the U.S..
Afterwards, get access to the needed content of user in the storage site of the IP address correspondence that can return according to content routing server in the step 303 of Edge Server.
Utilize above-mentioned distributed content management method, only in the part storage site under the situation of memory contents, the user can get access to the content that content supplier sends to this user region by the corresponding relation between classifying content sign and the storage site equally in content supplier.
The method of the distributed content management that the embodiment of the invention provides is by setting up the corresponding relation between classifying content sign and the storage site; The content routing server can obtain identifying corresponding storage site with classifying content according to described corresponding relation, and the address information of this storage site returned to the addressing client, make the addressing client find this storage site to carry out the injection or the download of content; Because the classifying content that content supplier can be provided is stored in the storage site corresponding with the classifying content sign, thereby refinement and then can improve the effective rate of utilization of memory space to the management of each storage site memory space; In addition,, can save the memory space of storage site to a certain extent like this, so that satisfy to the required memory space of newly-increased CP or to the autgmentability demand of the memory space of existing CP because classifying content is stored in the part storage site.
Embodiment two:
In the present embodiment, the corresponding relation between classifying content sign that prestores in the content routing server and the storage site provides another mapping table, sees Table 3.
Table 3
According to the mapping table in the table 3, the method for the distributed content management that present embodiment provides will be set forth at an instantiation.Suppose: the process that content is injected is that the CP1 of content supplier injects content to the part or all of storage site of the U.S., and the content process of downloading is that a user in the U.S. wishes to download the content of CP1 to U.S.'s issue.
At this instantiation, the distributed content management method that present embodiment provides specifically may further comprise the steps:
401, the content routing server receives the classifying content sign that the addressing client sends.
At the process that content is injected, in this instantiation, the addressing client is a content client.When the CP1 of content supplier injects content in the storage site of the U.S., send classifying content sign www.cp1.us.upload.cdn.net to the content routing server by content client.
At the content process of downloading, in this concrete enforcement, the addressing client is an Edge Server.U.S. user (for example: www.cp1.us) sends content requests to Edge Server, when in the Edge Server not this user need content the time, Edge Server sends classifying content sign www.cp1.us.download.cdn.net to the content routing server.
402, the corresponding relation set up according to the mapping table that prestores of content routing server obtains the corresponding storage site of described classifying content sign.
The process of injecting at content, in this instantiation, the content routing server is the part or all of storage site of the U.S. according to the storage site that the mapping table of table 3 finds classifying content sign www.cp1.us.upload.cdn.net correspondence.
At the content process of downloading, in this instantiation, the content routing server is the part or all of storage site of the U.S. according to the storage site that the mapping table of table 3 obtains classifying content sign www.cp1.us.download.cdn.net correspondence.
403, the content routing server returns to described addressing client with the address information of described storage site.
The process of injecting at content, according to step 402 as can be known the CP1 of content supplier to inject content to the storage site of the U.S., in this step, the IP address of the storage site that the content routing server is part or all of with the U.S. returns to content client; Afterwards, by content client content is injected into and the corresponding storage site of classifying content sign.
At the content process of downloading, according to step 402 as can be known this U.S. user wish that downloaded contents is kept in the part or all of storage site of the U.S., then the content routing server selects one or more available IP addresses to be back to Edge Server from the IP address of the part or all of storage site of the U.S.; Afterwards, from the storage site of the IP address correspondence returned, obtain the required content of this user by Edge Server.
In fact, in this instantiation,, get final product at the corresponding relation of preserving on the content routing server between classifying content sign and storage site at the mapping table in the table 3; User's use for convenience makes the user to find corresponding storage site by the CP class indication, so the corresponding relation of CP class indication and classifying content sign can be able to be stored in the addressing client.For example, inject this process for content, described addressing client can be a content client, the corresponding relation of storage CP class indication and classifying content sign in this content client, and in the content routing server corresponding relation between memory contents class indication and storage site.At this moment, content supplier can use CP class indication (www.cp1.us), find corresponding with it classifying content sign (www.cp1.us.upload.cdn.net) by content client, and this classifying content sign (www.cp1.us.upload.cdn.net) sent to the content routing server, find the corresponding storage site (storage site that the U.S. is all or part of) of this classifying content sign by the content routing server again, and the address information of this storage site is returned to content client.In addition, for the content process of downloading, can not repeat them here with reference to the process of foregoing injection.
Certainly, also can according to actual needs mapping table as shown in table 3 be set on the content routing server, set up corresponding relation in twos between CP class indication, classifying content sign and the storage site three according to this mapping table.
Similarly, if searching a certain content supplier uses domain name to add the path, then can a mapping table be set on the content routing server when the content of a certain storage site with reference to table 4.
Table 4
Certainly, table 3 does not conflict with mapping table in the table 4, can coexist on the content routing server.
Need to prove, in actual applications, corresponding relation between the classifying content set up in above-mentioned mapping table sign and the storage site can be stored in the content routing server, can also be mapped by the IP address of some algorithm, and these algorithms are arranged in the content routing server as mapping ruler classifying content sign and storage site or storage site.
The method of the distributed content management that the embodiment of the invention provides provides another mapping table for reference at the corresponding relation that prestores in the content routing server, and the specific implementation process is similar with the method for implementing in; This programme since the classifying content that content supplier can be provided be stored in the storage site corresponding with the classifying content sign, thereby by the management of refinement, and then can improve the effective rate of utilization of memory space to each storage site memory space; In addition,, can save the memory space of storage site to a certain extent like this, so that satisfy to the required memory space of newly-increased CP or to the autgmentability demand of the memory space of existing CP because classifying content is stored in the part storage site.
