Background Art

[0002] Content Delivery Network (CDN) has been used for many years in the fields of Internet audio and video transmission, IPTV network media transmission, etc. The core idea of ​​CDN is to push content to the service node closest to the user, so that the user can access the content nearby.

[0003] At present, it is a common demand of almost all CDN service providers to further sink the CDN service nodes. However, sinking the CDN service nodes means that the content is closer to the users on the one hand, but on the other hand it means an increase in the number of CDN nodes, making node management more difficult and increasing investment.

[0004] If the traditional method of adding physical nodes is used, it is necessary to conduct capacity assessment, hardware selection, subsequent software installation and update, manual online operations, etc. in advance, which is very inconvenient. In addition, based on the traditional CDN node installation method, a single CDN node uses a node-specific storage system in terms of storage system requirements. Some hot content requires high I / O throughput quality assurance, while some can use ordinary I / O quality. Moreover, the capacity is customized and difficult to change. When the node is sunk, each node is configured with the same physical device, and its I / O quality and capacity customization become very complicated and costly. Summary of the invention

[0073] The technical solution disclosed in the present invention is a combination of CDN technology and Mobile / Multi-access Edge Computing (MEC) technology. Figure 1a This is a schematic diagram of the logical functional architecture of multiple entities involved in the technical solution disclosed in this disclosure. Figure 1b A schematic diagram of a logical functional architecture of a MEC-CDN node in the technical solution disclosed in the present invention is shown in FIG. Figure 1a and Figure 1bAs shown, the technical solution of the present invention involves the following entities: CDN management node (also called CDN central node), mobile / multi-access edge application orchestrator (Mobile / Multi-access edge application orchestrator, referred to as MEAO) and mobile / multi-access edge computing-content distribution network node (MEC-CDN node).

[0074] Among them, the CDN management node has the function of managing CDN nodes, and provides configuration templates for creating MEC-CDN nodes (in the CDN management node, a variety of different configuration templates are stored in advance according to different needs). In the embodiment of the present disclosure, the CDN management node is mainly responsible for activating the process of creating a new MEC-CDN node (based on pre-set rules, judging whether a new MEC-CDN node needs to be created, and activating the creation process when a new MEC-CDN node needs to be created), parameter configuration of the new MEC-CDN node to be created (the CDN management node is provided with creation rules to determine the configuration template corresponding to the MEC-CDN to be created, and can generate a node creation request), and the maintenance of the stored configuration templates.

[0075] MEAO has the functions of orchestrating, managing and monitoring virtual resources, and guiding the Mobile / Multi-access Edge computing Platform (MEP) to instantiate MEC-CDN nodes. In the disclosed embodiment, MEAO can orchestrate and reserve virtual resources in the virtual resource pool according to the node creation request sent by the CDN management node, and control MEP to instantiate MEC-CDN nodes based on the orchestrated resources.

[0076] MEC-CDN node is a virtualized node, which can be composed of one or more virtualized functional modules that support business operations. In essence, MEC-CDN nodes include: MEC host, MEP, virtual basic resources, and virtualized functional modules running on MEP. Among them, the MEC host is responsible for loading MEP.

[0077] MEP provides an operating environment for CDN nodes based on MEC, and also provides the ability to expose CDN services to the outside world. Specifically, MEP can instantiate the virtualized functional modules contained in the MEC-CDN node under the guidance of MEAO, and provide a software platform for the virtualized functional modules. In the disclosed embodiment, the instantiated virtualized functional modules are run on MEP in the form of multi-access edge computing applications (MEC-APP). MEC-APP is used to implement various basic capabilities of MEC-CDN nodes, and ultimately acts as a logical service node to provide services to the outside world. Among them, MEC-APP exposes services through MEP.

[0078] Each virtualization function module has at least storage function and computing function; the storage function includes hard disk storage (Storage) function and cache (Buffer) function; the computing function includes at least one of the following: business load balancing function, storage function, distribution function, delivery function, media content management (including content processing) function; of course, some functions can be added or deleted according to the needs of actual deployment. It should be noted that in the embodiments of the present disclosure, the so-called "storage resources" include both hard disk storage resources and cache resources.

[0079] According to the different services supported, the virtualization function modules can be divided into virtualization function modules supporting IPTV services, virtualization function modules supporting OTT video services, virtualization function modules supporting VR live broadcast services, etc.; according to different service capabilities, the virtualization function modules can be divided into virtualization function modules with scheduling service functions, virtualization function modules with content management service functions, and virtualization function modules with media service functions, etc.

[0080] These virtualized function modules (MEC-APP) can be deployed on one MEP or on different MEPs, and provide corresponding services to the outside through the unified MEC-CDN node scheduling function. Among them, some virtualized function modules can register with MEP and open their own functions to other applications as a service.

[0081] It should be noted that in the technical solution disclosed in the present invention, MEP can also provide some common services, such as: local DNS resolution, support for access to underlying resources, and provide traffic control strategies.

[0082] The technical solution of the present disclosure will be described in detail below in conjunction with specific embodiments. In the following content, for the convenience of description, the virtualized function module is described in the form of MEC-APP.

[0083] Figure 2A flowchart of a CDN function virtualization management method provided by an embodiment of the present disclosure, such as Figure 2 The management method is applied to the CDN management node, and the management method includes:

[0084] Step S101: Send a node creation request to MEAO so that MEAO can control MEP to perform node instantiation processing and generate a MEC-CDN node. The MEC-CDN node includes at least one virtualization function module that supports business operations. The virtualization function module accesses the storage resource pool through the unified storage access interface provided by the storage resource management module.

[0085] The storage resource pool is a resource pool virtualized by providing storage resources from one or more physical devices with storage functions. Before generating an MEC-CDN node, a certain algorithm can be used to evaluate the storage resources required by the MEC-CDN node to be generated, and then a storage resource pool dedicated to the MEC-CDN node can be constructed based on the evaluation results (the capacity of the storage resource pool is customized).

[0086] Step S102: Connect the MEC-CDN node to the CDN.

[0087] After the MEC-CDN node is generated, it is necessary to initialize the service before it can provide services to the outside world. The initialization of the service requires the CDN management node to operate. After that, the MEC-CDN node will be connected to the original CDN system as a new CDN node. After the access is completed, the MEC-CDN node will provide customers with support for multiple business services like other normal CDN nodes in the CDN. The specific access process belongs to the conventional technology in this field and will not be repeated here. The technical solution disclosed in the present invention can enable CDN to quickly and dynamically support and expand multiple services.

[0088] In addition, in the disclosed embodiment, the MEC-APP in the MEC-CDN node accesses the storage resource pool through a unified storage access interface, which can shield the performance differences of different underlying storage devices constituting the storage resource pool for the upper-layer MEC-APP, so that all MEC-APPs in the MEC-CDN node can share the same storage resource pool. At this time, the storage resources allocated to each MEC-APP can be dynamically adjusted, so that the MEC-APP can provide the most appropriate storage access service for users and effectively utilize the actual storage space to the greatest extent.

[0089] In some embodiments, the storage resource pool includes: a virtual storage resource pool and / or a physical storage resource pool. That is, the storage resources in the storage resource pool can be pure virtual storage resources, pure physical storage resources, or a combination of virtual storage resources and physical storage resources. Among them, the physical storage resources are provided by a dedicated physical storage device, and its access interface is independent of the virtual storage resource access interface.

[0090] In some embodiments, the virtual storage resource pool includes: virtualized high-performance storage resources and virtualized low-performance storage resources; wherein the performance parameters of the virtualized high-performance storage resources are better than preset performance indicators, and the performance parameters of the virtualized low-performance storage resources are worse than preset performance indicators. As an example, the performance parameter is selected as the read and write speed of the storage device, and the preset performance indicator is set to 600M / s, then the virtualized high-performance storage resource refers to a storage resource with a read and write speed greater than 600M / s, and the virtualized low-performance storage resource refers to a storage resource with a read and write speed less than or equal to 600M / s. Of course, in the embodiments of the present disclosure, the performance parameters used to divide high / low performance storage can also use other parameters, which will not be described one by one by examples here.

[0091] In some embodiments, the unified storage access interface includes one or a combination of the following interfaces: a first access interface, a second access interface, and a third access interface; wherein the first access interface is configured for the virtualization function module to access virtualized high-performance storage resources; the second access interface is configured for the virtualization function module to access virtualized low-performance storage resources; and the third access interface is configured for the virtualization function module to directly access physical storage resources in a physical storage resource pool. In actual applications, the combination of these access interfaces can be automatically configured according to changes in storage resources.

[0092] In some embodiments, a plurality of different configuration templates are pre-stored in the CDN management node, and each configuration template can be used to generate a corresponding MEC-CDN node; the configuration template records the configuration scheme of the corresponding MEC-CDN node, including at least one or more of the following contents: computing resources for realizing various business functions, network bandwidth resources required for data transmission, storage space resources for content storage, storage I / O throughput bandwidth, etc. When the CDN management node determines that the CDN network needs to create a new MEC-CDN node, it can determine a suitable configuration template according to actual needs, add the address information of the determined configuration template to the node creation request, and send the node creation request to MEAO.

[0093] After receiving the node creation request, MEAO obtains the configuration template of the MEC-CDN node to be generated according to the address information contained in the node creation request. Therefore, between step S101 and step S102, the following may also be included: step S101a, providing the configuration template of the MEC-CDN node to be generated to MEAO.

[0094] As an optional implementation method for configuring the storage resource management module, the configuration template records a first generation instruction, and MEAO can control MEP to configure the storage resource management module in its own platform according to the first generation instruction. Among them, the upper-level APP needs to go through the "discovery" step before it can use the storage resource management module configured by MEP.

[0095] As another optional implementation method for configuring the storage resource management module, a second generation instruction is recorded in the configuration template, and MEAO can control MEP to instantiate a virtualization function module as the storage resource management module according to the second generation instruction. Among them, the storage resource management module can provide a unified storage access interface for MEC-APPs of different upper-level businesses to access the storage resource pool by registering with MEP as a general storage management service, thereby providing storage services to the outside.

[0096] As another optional implementation method for configuring the storage resource management module, a third generation instruction is recorded in the configuration template so that MEAO can control the virtual abstraction layer of the storage resource pool to configure the storage resource management module according to the third generation instruction. Among them, the storage management module directly takes over the underlying resource access path, so the upper-layer business, regardless of the differences in the underlying resources, must go through this interface as long as it accesses the storage resources, that is, the storage management module can be used as a general storage service capability to provide upper-layer businesses with direct access to storage resources. Reading service.

[0097] That is, the storage resource management module can exist as a platform-level service function of the MEP, or run on the MEP as a virtualized function module within the MEC-CDN node, or be deployed in the virtual abstraction layer that controls the storage resource pool as a file system function.

[0098] In some embodiments, the storage resource management module is also configured with storage resource adjustment policy data, and the storage resource adjustment policy data is used for the storage resource management module to dynamically adjust the storage resources allocated to each virtualization function module in the MEC-CDN node according to a preset adjustment strategy.

[0099] In actual applications, the storage resource management module can dynamically adjust the storage resources allocated to at least one MEC-APP in the MEC-CDN node in response to adjustment requests sent by external functional modules (such as MEC-APP, CDN management node, and other logical modules of the MEC service system). Alternatively, a monitoring function module is configured in the MEC system, which can monitor the access status of each MEC-APP in the MEC-CDN node (for example, the number of visits to certain specific content in the MEC-APP within a unit period, request traffic, etc.) and generate monitoring data. The storage resource management module dynamically adjusts the storage resources allocated to the MEC-APP based on these monitoring data and the pre-written storage resource adjustment policy. Exemplarily, when the number of accesses to specific content in MEC-APP within a unit period is greater than the first preset number threshold, the storage I / O throughput bandwidth allocated to the MEC-APP can be expanded; when the number of accesses to specific content in MEC-APP within a unit period is less than the second preset number threshold (less than the first preset number threshold), the storage I / O throughput bandwidth allocated to the MEC-APP can be reduced. When the request traffic of specific content in MEC-APP within a unit period is greater than the first preset traffic threshold, the storage space allocated to the MEC-APP can be expanded; when the number of accesses to specific content in MEC-APP within a unit period is less than the second preset traffic threshold (less than the first preset traffic threshold), the storage space allocated to the MEC-APP can be reduced. It should be noted that the technical solution disclosed in this disclosure does not limit the specific storage resource adjustment strategy.

[0100] In the disclosed embodiment, the dynamic adjustment of the storage resources allocated by the virtualization function module includes at least one of the following: storage space size adjustment, access path adjustment, I / O bandwidth adjustment, and storage device migration adjustment. Of course, when the storage resource pool includes virtual storage resources, the adjustment of the storage resources allocated by the virtualization function module may also include adjusting the ratio of the allocated virtualized high-performance storage resources to the virtualized low-performance storage resources.

[0101] Figure 3 A flowchart of another CDN function virtualization management method provided by an embodiment of the present disclosure, such as Figure 3 The management method is applied to the CDN management node. The management method includes not only the above-mentioned step S101 and step S102, but also step S103. Only step S103 is described in detail below.

[0102] Step S103: Send a storage resource adjustment request to the storage resource management module so that the storage resource management module can adjust the storage resources corresponding to at least one virtualization function module in the MEC-CDN node.

[0103] In the disclosed embodiment, the CDN management node may adjust the storage resources allocated to each MEC-APP in the MEC-CDN node according to actual needs.

[0104] Figure 4 A flowchart of another CDN function virtualization management method provided by an embodiment of the present disclosure is shown in FIG. Figure 4 As described above, the management method is applied to the CDN management node. The management method not only includes the above-mentioned step S101 and step S102, but also includes: step S104. Only step S104 is described in detail below.

[0105] Step S104: Send a policy adjustment request to the storage resource management module to adjust the storage resource adjustment policy data in the storage resource management module.

[0106] When storage resource adjustment policy data is configured in the storage resource management module, the CDN management node can adjust the storage resource adjustment policy data stored in the storage resource management module according to actual needs.

[0107] It should be noted that for Figure 2 to Figure 4 Different steps in the illustrated embodiments may be combined, and the technical solutions obtained by the combination should also fall within the protection scope of the present disclosure.

[0109] Step S201: In response to a node creation request sent by a CDN management node, resource orchestration is performed according to the node creation request.

[0110] Step S202: Control the MEP to perform node instantiation processing to generate a MEC-CDN node. The MEC-CDN node includes at least one virtualization function module that supports business operation. The virtualization function module accesses the storage resource pool through the unified storage access interface provided by the storage resource management module.

[0111] In some embodiments, before step S202, when MEAO determines that no MEP exists in the MEC host, MEAO controls the MEC host to first create the MEP, and then instructs the MEP to perform node instantiation processing.

[0112] In some embodiments, the node creation request records the address information of the configuration template; step S201 includes: obtaining the configuration template according to the address information; and performing resource arrangement according to the configuration template.

[0115] As another optional implementation of configuring the storage resource management module, a third generation instruction is recorded in the configuration template, and the method further includes: controlling the virtual abstraction layer of the storage resource pool to configure the storage resource management module according to the third generation instruction.

[0116] In some embodiments, the storage resource management module is also configured with storage resource adjustment policy data, and the storage resource adjustment policy data is used for the storage resource management module to dynamically adjust the storage resources allocated to each virtualization function module in the MEC-CDN node according to a preset adjustment strategy.

[0117] In some embodiments, the storage resource pool includes: a virtual storage resource pool and / or a physical storage resource pool.

[0118] In some embodiments, the virtual storage resource pool includes: virtualized high-performance storage resources and virtualized low-performance storage resources; wherein the performance parameters of the virtualized high-performance storage resources are better than preset performance indicators, and the performance parameters of the virtualized low-performance storage resources are worse than preset performance indicators.

[0119] In some embodiments, the unified storage access interface includes one or a combination of the following interfaces: a first access interface, a second access interface, and a third access interface; wherein the first access interface is configured for the virtualization function module to access virtualized high-performance storage resources; the second access interface is configured for the virtualization function module to access virtualized low-performance storage resources; and the third access interface is configured for the virtualization function module to directly access physical storage resources in a physical storage resource pool.

[0133] BZ1, CDN management node sends a node creation request to MEAO; the node creation request includes the download address information of the node configuration template.

[0134] BZ2 and MEAO download the configuration template of the MEC-CDN node to be created according to the address information of the configuration template in the node creation request.
