Description

A method for realizing service and media controller

technical field

The invention relates to the technical field of communication, in particular to a method for realizing service and a media controller.

Background technique

With the development of network access, wireless interconnection, and digital media technology, how to realize user-customized media services is a key technical direction.

In the prior art, when a user subscribes to a media service, the media service can only be deployed on one media device, that is, the media service can only be realized through one media device, because the realization of the media service requires the provision of corresponding functions Supported, so the media device must have the functional resources required to provide this functionality. As shown in Figure 1-a, the Digital Living Network Alliance (DLNA) standard defines a Digital Media Server (DMS) service, and the implementation of the DMS service requires demodulation (demod) function, demultiplexing ( demux) function, decoding (decoder) function, encoding (encoder) function and lossless extraction (remux) function support, when the DMS service is deployed on a media device, the media device must have demod module, demux module, decoder module, encoder module and remux module to provide the above functionality.

However, there are the following defects when using the existing technology to realize the media service: (1) When the existing media device has the functional resource, the functional resource is used by the existing media device to provide other media services. It is necessary to wait for the existing media device to complete other services to release the functional resources. For example, the media device in Figure 1-b uses the decoder module to provide digital media player (Digital Media Player, DMP) services. At this time, it is necessary to wait until the The DMS service can only be provided after the media device completes the DMP service, which affects the efficiency of media service implementation; (2) When the existing media device does not have this functional resource, it is necessary to add a media device with this functional resource, as shown in Figure 1 In -c, the media device 1 and media device 2 lack the remux module required to realize the DMS service. At this time, it is necessary to add the media device 3 with the remux module, resulting in an increase in investment in device assets.

All the modules are used to realize the purpose of the solution of the embodiment of the present invention.

A method for providing services and a media controller provided by the embodiments of the present invention are mainly used in the field of home interconnection technology, and by referring to Network Function Virtualization (Network Function Virtualization, NVF) technology and Software Defined Network (Software Defined Network, SDN) ) technology, which abstracts (virtualizes) media services into a logical or virtual entity (Virtual Device Unit, VDU), and abstracts the functions of the same category of multiple media devices (Physical Device Unit, PDU), thereby defining logical functional units (Logic Function Unit, LFU) set, which forms the mapping between PDU and LFU, and then maps the VDU into a series of LFU, that is, forms the mapping between VDU and LFU, so that when the media controller receives the service request, it can Utilizing the mapping between VDU and LFU and the mapping between PDU and LFU, among the functional resources of the existing equipment, the scheduling of the functional resources required for the service requested in the service request is realized to improve service provision. efficiency and save equipment cost.

Among them, SDN technology mainly abstracts network functions and service processing, and controls these abstracted objects through external controllers, separates the control and forwarding of network services, and divides them into control plane and forwarding plane, and the control plane and A standard interface is provided between the forwarding planes; NFV technology mainly normalizes various network elements in the network into a standard high-capacity through the decoupling of logical functions and physical hardware, and the virtualization of all network element devices in the entire communication network servers, storage and data switches.

Among them, when virtualizing the media device PDU, it is necessary to complete the mapping from LFU to PDU and from VDU to LFU through the description of the LFU template and the description of the VDU template. The description of the LFU template and VDU template can be used for reference. Virtualization Model (Virtualization Model of Manufacturing Resource, VMMR). When describing the template, you can refer to the object-oriented idea to abstract a group of objects of the same nature. The template needs to contain at least the following six-tuples:

The global identifier refers to the global unique identifier (URI) of the template, and the template of this type can be found and accessed through the URI.

The basic information of the resource refers to the basic information (BasicInfo) of the template, which can visually explain information such as the name and function of the type described in the template.

The attribute set refers to the attribute set of the template, which specifically includes the attribute name (AttrName), the data type of the attribute (DataType), the initial value of the attribute (InitValue), and the constraint set of the attribute (ConstraintSet).

The operation set refers to a set of standardized interface descriptions for direct use, job scheduling, and information transfer after a certain type of resource is service-encapsulated. The standardized interface description set specifically includes the service interface name (Name), interface input ( Input), interface output (Output) and interface exception information (FaultMessage).

State collection refers to the collection of all possible states of resources, including the collection of various states of resources in use, idle, maintenance and other stages, and the state transition is completed by the interface.

Relationship collection, which is used to represent the inheritance relationship between templates. The lower template not only inherits all the attributes, operations, states and relationships of the upper template, but also extends it. Through the description of the inheritance relationship of the template, it can not only guarantee the same type of resource description The unity of the method can also enable some resources with special attributes to be effectively described and play a role.

After the template is described in the above manner, since the same type of device resources use the same template, the purpose of describing virtual resources by type can be achieved, and then the accurate description, good management and effective allocation of specific VDU and LFU resource virtualization can be achieved. The purpose of the class is to accurately query such device resources with similar functions and the same role by customizing templated query conditions, and in the use of device resources, the same interface is used for the device resources of the same template type, and the resources are normalized , making intelligent scheduling possible.

Among them, as shown in Figure 2, there are two types of mapping between PDU and LFU: 1:1 mapping, 1:n mapping, and there are three types of mapping between LFU and VDU: 1:1 mapping, 1:n mapping, n :1 mapping, where the VDU is composed of LFUs from the same or different PDUs, which is a new logical function generated by LFU reconstruction and exists independently of the PDU, that is to say, through the mapping algorithm, the functions provided by the PDU are abstracted into mutual The independent logical function unit LFU forms the VDU through the reorganization of the LFU.

Referring to Figure 3, an embodiment of a method for providing a service in the embodiment of the present invention includes:

101. The media controller determines the target virtual device unit VDU corresponding to the target service according to the service request sent by the media terminal.

It can be understood that the media terminal can determine the requested service according to the service requirements, and send a service request containing the target service to the media controller, and when receiving the service request sent by the media terminal, the media controller For the target service, determine the target VDU corresponding to the service.

102. The media controller searches for the target LFU corresponding to the target VDU according to the preset mapping relationship between the VDU and the LFU.

It can be understood that a VDU template is predefined in the media controller, wherein the mapping relationship between VDU and LFU is defined in the VDU template, and the VDU template can be manually defined in advance. The definition can be understood as giving A set of parameters; for example, the definition of the VDU template can be understood as giving the parameters of the VDU template; the definition of the mapping relationship between VDU and LFU can be understood as giving the mapping of VDU and LFU parameters of the relationship.

It can be known from the above that after the target VDU of the target service is determined, the target LFU corresponding to the target VDU can be determined according to the mapping relationship between the VDU and the LFU.

103. The media controller searches for the PDU set that provides the target LFU according to the preset mapping relationship between the LFU and the PDU set.

It can be understood that an LFU template is also predefined in the media controller, wherein the LFU template defines the mapping relationship between the LFU and the PDU set. The definition of the LFU template can be understood as giving the LFU template Parameters; the definition of the mapping relationship between the LFU and the PDU set can be understood as the parameters of the mapping relationship between the LFU and the PDU set.

It can be known from the above that after determining the target LFU to provide services, the PDU set corresponding to the target LFU can be determined according to the mapping relationship between the LFU and the PDU set, where the PDU set can be a type of PDU set or multiple Types of PDU sets.

It can be understood that after the media controller determines the PDU set providing the target LFU, it can use the functions provided by any PDU in the PDU set to process the service data corresponding to the target service, so as to ensure that the target service can be realized.

In the embodiment of the present invention, the media controller abstracts the media service into a logical or virtual entity VDU in advance by referring to NVF technology and SDN technology, and abstracts the functions of the same category of multiple media devices (PDUs), thereby defining logical functional units (LFU) set, and then map the VDU into the LFU set, when determining the target VDU corresponding to the service, use the mapping relationship between the VDU and the LFU to determine the target LFU, and then use the mapping relationship between the LFU and the PDU set to determine the provision of the target The PDU set of LFU, and then select the target PDU from the PDU set. Since the target LFU can be provided by different PDUs, when the target LFU provided by a certain PDU in the PDU set is occupied by other services, the target can be provided by other PDUs. LFU can execute the target service without waiting for other services to be completed, thus improving the efficiency of target service provision, and when a PDU in the PDU set cannot provide the target LFU, it can be provided by multiple PDUs, without adding new equipment, saving investment in equipment assets.

In the embodiment of the present invention, as a logical service, the VDU resource is associated with the LFU resource through a mapping relationship, and the physical resource PDU expresses a series of functions through abstraction. The tight coupling relationship between VDU services, that is, the source service capability is not directly related to specific physical resources, and the resource mapping is established by the intermediate control layer according to the mapping rules to establish the mapping relationship between services and physical resources, so as to improve the utilization of physical resources rate purposes.

Through the adaptation of the control layer middleware, specific PDU physical resources are encapsulated into various standard LFU functional resources, mapped with VDU service resources, registered and published as VDU services.

In order to realize the service classification description, define the VDU resource template, determine its attribute set and standardized interface. Use and manage such services to provide standard specifications.

In order to shield the heterogeneity of physical resource PDUs, the embodiment of the present invention standardizes and encapsulates the PDUs according to the LFU interface specification, registers and releases the supported LFU function set, and completes the mapping relationship between the PDUs and the LFUs.

Please refer to Figure 4, based on the embodiment method shown in Figure 3, another method for providing services in the embodiment of the present invention includes:

201. The media controller determines the target VDU corresponding to the target service according to the service request sent by the media terminal.

202. The media controller searches for the target LFU corresponding to the target VDU according to the preset mapping relationship between the VDU and the LFU.

203. The media controller searches for the PDU set that provides the target LFU according to the preset mapping relationship between the LFU and the PDU set.

In some embodiments of the present invention, when the target service requires multiple LFUs, that is, the target LFU includes multiple LFUs, for example, the target LFU may include a first LFU and a second LFU, and the PDU set is a PDU combination set, Each PDU in the PDU set is a PDU combination.

Optionally, step 202 in this embodiment may specifically include:

202a. The media controller searches for the first LFU and the second LFU corresponding to the target VDU according to the preset mapping relationship between the VDU and the LFU.

It can be understood that a VDU template is predefined in the media controller, and the mapping relationship between VDU and LFU is defined in the VDU template, and the mapping relationship between VDU and LFU is defined. It can be understood that the VDU A description of the mapping relationship with the LFU. According to the mapping relationship, the first LFU and the second LFU corresponding to the target VDU can be found; for example, when the target VDU is VDU1, the target LFUs corresponding to the VDU1 are LFU1 and LFU2.

The specific mapping relationship parameters between VDU and LFU are shown in Table 1 below:

VDU1 LFU1, LFU2 VDU2 LFU3, LFU4

In some embodiments of the present invention, the same LFU can be provided by multiple PDUs of the same type, therefore, one LFU can correspond to one PDU set.

Optionally, when step 202 is performed according to step 202a, step 203 in this embodiment may specifically include:

203a. The media controller searches for a first PDU set providing the first LFU and a second PDU set for the second LFU according to the preset mapping relationship between LFUs and PDUs.

It can be understood that after determining the target LFU to provide services, the first PDU set corresponding to the first LFU and the second PDU set corresponding to the second LFU can be determined according to the mapping relationship between the LFU and the PDU. For example, when the target LFU is determined When it is LFU1 and LFU2 in Table 1, according to the mapping relationship in Table 2, it can be determined that the PDU set providing the LFU1 includes PDU1 and PDU2, and the PDU set providing LFU2 includes PDU3 and PDU4.

The mapping relationship between LFU and PDU is shown in Table 2:

LFU1 PDU1 or PDU2 LFU2 PDU3 or PDU4

203b. Combine the first PDU set and the second PDU set according to a preset rule.

It should be noted that the combination rules for different types of PDUs can be preset in the media controller. For example, the rule is that PDU1 can only be used in combination with other PDUs on the same board, as shown in Table 2 Multiple PDUs, if PDU1 and PDU3, PDU2 and PDU4 come from two different boards, then according to this rule, after combining the first PDU set and the second PDU set, the obtained PDU set is PDU1 and PDU3, PDU2 and PDU3, PDU2 and PDU4.

In some embodiments of the present invention, when the VDU corresponds to only one LFU, that is, the target LFU is one LFU, one LFU can be provided by any one of multiple PDUs with the same function.

Optionally, step 203 in this embodiment may specifically include:

203b. The media controller searches for the PDU set that provides the target LFU according to the preset mapping relationship between the LFU and the PDU set.

It can be understood that after the target LFU providing the target VDU is determined, the PDU set corresponding to the target LFU can be determined according to the mapping relationship between the LFU and the PDU set, for example, when the target LFU is determined to be LFU1 in Table 1, according to the table The mapping relationship in 2 can determine that the PDU set providing the LFU1 includes PDU1, PDU2, PDU3 and PDU4.

Optionally, when step 203 is specifically executed according to 203b, step 204 in this embodiment may specifically include:

204c. Acquire load status information sent by each PDU in the PDU set, where the load status is used to indicate a current load value of each PDU.

Wherein, the media controller may obtain the load value of each PDU from the load status information sent by each PDU in the PDU set.

Table 5 below shows the load value of each PDU in the PDU set

Physical Equipment Unit load value PDU1 53 PDU2 89 PDU3 77 PDU4 41

204d. According to the load value of each PDU in the PDU set, select a PDU with the smallest load value from the PDU set as the first PDU.

As can be seen from Table 5, the PDU4 with the smallest PDU concentration load value is selected as the first PDU.

It should be noted that, the manner in which the media controller obtains the load value of each PDU in the PDU set may be that the media controller sends an instruction to each PDU to make the PDU return information containing the load value, or the PDU may periodically Actively report the information including the load value to the media controller.

In some embodiments of the present invention, after step 203, step 204 and step 205 may also be included:

204. Acquire load status information sent by each PDU in the PDU set, where the load status is used to indicate a current load value of each PDU.

Wherein, the media controller may obtain the load value of each PDU from the load status information sent by each PDU in the PDU set.

Table 4 below shows the load value of each PDU in the first PDU set and the second PDU set

PDU combination set load value PDU1 and PDU4 53 PDU2 and PDU3 89 PDU2 and PDU3 68

205. According to the load value of each PDU in the PDU set, select a PDU with the smallest load value from the PDU set as the first PDU.

As shown in Table 4, the combined load of PDU1 and PDU4 is the smallest. Therefore, selecting PDU1 and PDU4 with the smallest combined load of PDUs as the first PDU can avoid the instability of the target service due to the excessive combined load of PDUs.

It should be noted that, the manner in which the media controller obtains the load value of each PDU in the PDU set may be that the media controller sends an instruction to each PDU to make the PDU return information containing the load value, or the PDU may periodically Actively report the information including the load value to the media controller. Wherein, the load state information may include pressure from the memory to the bus, CPU load, and the like.

In some embodiments of the present invention, after step 205, step 206 and step 207 may also be included:

206. Acquire first information sent by the first PDU, where the first information is used to indicate a current running state of the first PDU.

Wherein, the first PDU may periodically or non-periodically feed back its own running state to the media controller, specifically, it may send first information to the media controller, and the first information is used to indicate the current running state of the first target PDU , the running status includes normal and abnormal.

It should be noted that the PDU may actively send the first information, or may passively send the first information when receiving an instruction from the media controller, which is not specifically limited here.

207. When it is determined according to the first information that the first PDU is running abnormally, select a second PDU from the PDU set, and the second PDU is the load value of the PDU set except the first PDU The smallest PDU, the second PDU is used to provide the target LFU.

It can be understood that when the first information sent by the first PDU indicates that the current working state of the first PDU is abnormal, the media controller selects the PDU with the smallest load value except the first PDU from the PDU set as the second PDU. Two PDUs, the second PDU is used to provide the target LFU. For example, when step 203 is performed according to 203a, PDU2 and PDU3 may be selected as the second PDU, and when step 203 is performed according to 203b, PDU1 may be selected as the second PDU.

It should be noted that, in this embodiment, when it is determined that the first PDU is abnormal, the media controller selects the PDU with the smallest load value as the second PDU. Avoid the problem of service instability caused by too much PDU load value. In practical applications, other PDUs in the PDU set may also be selected as the second PDU, which is not specifically limited here.

Optionally, before step 202 in this embodiment of the present invention, the media controller may also acquire third information, where the third information carries a mapping relationship between VDUs and LFUs. For example, copying or downloading data information including the mapping relationship between the VDU and the LFU from the external storage is to install the VDU service.

Optionally, before step 203 in the embodiment of the present invention, the media controller may also perform the following steps:

Receive the second information sent by the PDU, the second information is used to indicate the LFU provided by each PDU in the PDU set, and when the LFU provided by each PDU is the same, create a mapping relationship between the LFU and the PDU set according to the LFU template.

For ease of understanding, a method for implementing services in the embodiment of the present invention is described in detail below in conjunction with specific application scenarios. Please refer to FIG. 5-a to FIG. , MR) there are 4 in total (ie MR1, MR2, MR3, MR4). In the embodiment of the present invention, the process of using the media router to provide services includes:

301. The media controller encapsulates functional resources that can be provided by the media routers MR1, MR2, MR3, and MR4 into an LFU.

It can be understood that the media controller encapsulates the functional resources provided by the media routers MR1, MR2, MR3, and MR4 into LFUs, that is, the LFU template in the media controller maps the functional resources of MRs into LFUs, as shown in Figure 5- a. Encapsulate the functional resources in MR1 into access function, demultiplexing (demux) function, lossless extraction (remux) function, and encoding (encoder) function, and encapsulate the functional resources in MR2 into audio decoder (audio decoder) Function, graphic decoding (jpg decoder) function, demultiplexing (dumux) function, audio encoding (audio encoder) function, encapsulation of functional resources in MR3 into audio decoding (audio decoder) function, audio encoding (audio encoder) function, lossless Extraction (remux), decoding (decoder) functions, package functional resources in MR4 into access (access) function, audio encoding (audio encoder) function, lossless extraction (remux), decoding (decoder) function and other LFU resources.

302. The media controller determines the target LFU resource required by the screen transfer service according to the screen transfer service request sent by the media terminal.

In this embodiment, the media controller may determine that the target LFU resources required by the screen transition service are access, demux, audio decoder, and audio encoder according to the service deployment policy.

303. The media controller determines, according to the load value of the media routers, that MR1 and MR2 provide the target LFU resources.

It can be understood that the media controller can obtain the current load value of the media router where the LFU is located, such as detecting the load value of the media router through a pressure sensor. The load value can be the pressure from the memory to the bus or the CPU load, etc. The load values of MR1, MR2, MR3 and MR4 are shown in Table 6 below:

Table 6

MR1 43 MR2 42 MR3 55 MR4 47

It can be seen from Table 6 that among MR1 and MR4 where the access required for the screen transfer service is located, the load value of MR1 is smaller than that of MR4. Therefore, the access of MR1 is used as the LFU resource required for the screen transfer service. Similarly, the demux and MR1 of MR1 are selected. MR2's audiodecoder and audio encoder. As shown in Figure 5-b, the media controller selects the access and demux in MR1, and the audiodecoder and audio encoder in MR2 to provide the LFU resources required for the screen transfer service, and uses MR1 and MR2 to process the business data of the screen transfer service, Output the data required for the service to the media terminal, so as to realize the user-customized screen transfer service.

304. When it is determined that MR1 is running abnormally, select demux in MR2 and access in MR4 to provide the screen switching service.

It can be understood that the media controller can monitor and analyze the running status of the media router associated with the screen switching service through periodic sampling or an active notification mechanism to determine or predict whether a runtime exception occurs. Table 7 below shows the running status of each media router:

Table 7

MR1 abnormal MR2 normal MR3 normal MR4 normal

As shown in Figure 5-c, when the media controller determines that MR1 is abnormal, it will select the demux in MR2 and the access in MR4 to replace the demux and access in MR1, so as to continue to implement the screen transition service.
