nullA kind of method that service is provided of embodiment of the present invention offer and media controller，It is mainly used in family's field of interconnection technologies，By using for reference network function virtualization (Network Function Virtualization，NVF) technology and software defined network (Software Defined Network，SDN) technology，It is a logic or pseudo-entity (Virtual Device Unit by abstract for media services (virtualization)，VDU)，By multiple media devices (Physical Device Unit，PDU) generic function carries out abstract，Thus define logic function unit (Logic Function Unit，LFU) collection，I.e. form the mapping between PDU and LFU，Again this VDU is mapped to a series of LFU，I.e. form the mapping between VDU and LFU，Make media controller when receiving service request，The mapping between the mapping between this VDU and LFU and PDU and LFU can be utilized，In the functional resources that existing equipment is had，Realize the functional resources needed for the service asked in service request is scheduling thus reach to improve the efficiency that service provides，And saving equipment cost.

Wherein, SDN technology is mainly by network function and Business Processing abstract, and the object of these abstracts is controlled by external controller, control and the forwarding of Network are separated, it is divided into control plane and Forwarding plane, and controls to provide between plane and Forwarding plane a standard interface；NFV technology is mainly by logic function and the decoupling of physical hardware, and the various network element normalizings in network are become the server of high power capacity, memorizer and the data switching exchane of standard by the virtualization of all network element devices in whole communication network.

Wherein, when media device PDU is virtualized, the description with VDU template that describes by LFU template is needed to complete the mapping of the mapping to LFU to PDU, VDU to LFU, the description of this LFU template and VDU template can use for reference manufacturing recourses virtualization model (Virtualization Model of Manufacturing Resource, VMMR).When carrying out template and describing, specifically it is referred to Target-oriented thought, the object of one group of same nature is carried out abstract, template needs to comprise following hexa-atomic group:

Global identifier, refers to the globally unique indications (URI) of template, can search and access the type template by URI.

Resource essential information, refers to the essential information (BasicInfo) of template, the information such as title and effect that type described by this template can be described intuitively.

Community set, refer to the community set of template, this community set specifically includes Property Name (AttrName), the data type (DataType) of attribute, the initial value (InitValue) of attribute, the constraint set (ConstraintSet) of attribute.

Operational set, refer to a certain resource type after serviceization encapsulates, for directly use, job scheduling, the standard interface description collections of information transmission, this standard interface description collections specifically includes the title (Name) of service interface, interface input (Input), interface output (Output) and the abnormal information (FaultMessage) of interface.

State set, refers to the set of the there may exist state of resource, comprises the resource set at the various different conditions in the stages such as use, free time, maintenance, and the conversion of state is completed by interface.

Set of relationship, for representing the inheritance between template, lower template not only inherits all properties of upper former, operation, state and relation, and it is extended, described by the inheritance of template, the uniformity in same type resource description mode can either be ensured, the resource of some specific properties can also be enable effectively to describe simultaneously, play a role.

After in the manner described above template being described, owing to same type of device resource uses same template, the purpose that virtual resource classifying type is described can be reached, and then reach the accurate description of concrete VDU and LFU resource virtualizing, good management and the purpose effectively sorted out, to this kind of functional similarity, act on identical device resource, accurately can be inquired about by the querying condition of custom built forms, and in device resource uses, device resource for same template type uses same interface, resource normalization so that intelligent scheduling is possibly realized.

Wherein, as Fig. 2 PDU has two types: 1:1 mapping, 1:n to map with the mapping relations between LFU, LFU has three types: 1:1 to map with the mapping relations between VDU, 1:n maps, n:1 maps, wherein, VDU is made up of the LFU from identical or different PDU, it it is the new logic function produced by LFU reconstruct, and exist independent of PDU, that is mapping algorithm is passed through, the function modeling that PDU provides is become separate logic function unit LFU, by the restructuring of LFU, form VDU.

Referring to Fig. 3, in the embodiment of the present invention, a kind of embodiment providing method of servicing includes:

101, the service request that media controller sends according to media termination, determines the target virtual devices unit VDU that destination service is corresponding.

It is understood that media controller is after determining the PDU collection providing described target LFU, it is possible to use the function that any PDU that this PDU concentrates is provided, process this destination service correspondence business datum, so that it is guaranteed that be capable of this destination service.

nullIn the embodiment of the present invention，Media controller use for reference NVF technology and SDN technology in advance by abstract for media services be a logic or pseudo-entity VDU，And the generic function of multiple media devices (PDU) is carried out abstract，Thus define logic function unit (LFU) collection，This VDU is mapped to this LFU collection again，When target VDU determining that service is corresponding，Utilize the mapping relations of VDU Yu LFU，Determine target LFU，The mapping relations of recycling LFU Yu PDU collection，Determine the PDU collection that described target LFU is provided，Then concentrate from PDU and choose target PDU，Owing to this target LFU can be provided by different PDU，When this target LFU that certain PDU that this PDU concentrates provides is accounted for by other services，This target LFU can be provided by other PDU，Could performance objective service after completing without waiting for other services，Therefore the efficiency that destination service provides is improved，And when the PDU that PDU concentrates cannot provide this target LFU，Jointly can be provided by multiple PDU，Without increasing new equipment，Save the input of asset of equipments.

In the embodiment of the present invention, VDU resource is as a kind of logical services, pass through mapping relations, together with LFU resource associations, physical resource PDU is by abstract, show a series of function, this association is loose coupling form, thus release the close coupling relation between PDU physical resource and VDU service, i.e. source service ability is not directly associated with concrete physical resource, resource maps by Intermediate Control Layer according to mapping ruler, sets up the mapping relations between service and physical resource, thus reaches to improve the purpose of physical resource utilization rate.

By the adaptation of key-course middleware, concrete PDU physical resource is encapsulated as the LFU functional resources of each class standard, sets up with VDU Service Source and map, register and be issued as VDU service.

Describe to realize classification of service type, definition VDU resource template, determine its community set and standard interface, this VDU resource template is not only the virtualization encapsulation of specific service in key-course and provides template and reference, and the structure use being upper layer application by standardized service interface manages such service etc. and provides standard criterion.

In order to shield the isomerism of physical resource PDU, PDU is standardized encapsulation according to LFU interface specification by the embodiment of the present invention, and externally the LFU function set supported is issued in registration, completes the mapping relations of PDU Yu LFU.

Referring to Fig. 4, based on the embodiment method shown in Fig. 3, in the embodiment of the present invention, another provides the method for service to include:

201, the service request that media controller sends according to media termination, determines target VDU that destination service is corresponding.

202, described media controller is according to the mapping relations of preset VDU and LFU, searches target LFU that described target VDU is corresponding.

203, described media controller is according to the mapping relations of preset LFU and PDU collection, searches the PDU collection providing described target LFU.

In some embodiments of the invention, when described destination service needs multiple LFU, the most described target LFU includes that multiple LFU, such as target LFU can include a LFU and the 2nd LFU, described PDU integrates as PDU combination of sets, and each PDU that described PDU concentrates is a PDU combination.

Alternatively, the step 202 in the present embodiment specifically may include that

202a, described media controller, according to the mapping relations of preset VDU and LFU, search a described target VDU corresponding LFU and the 2nd LFU.

It is understandable that, predefined in media controller have VDU template, the mapping relations of VDU Yu LFU defined in described VDU template, the described mapping relations defining VDU Yu LFU, can be understood as, give the description of the mapping relations of VDU Yu LFU, a target VDU corresponding LFU and the 2nd LFU can be found out according to these mapping relations；Such as, when target VDU is VDU1, target LFU corresponding for this VDU1 is LFU1 and LFU2.

The mapping relations parameter of concrete VDU Yu LFU, such as table 1 below:

VDU1	LFU1、LFU2
		VDU2	LFU3、LFU4

In some embodiments of the invention, same LFU can be provided by the PDU of multiple same types, and therefore, a LFU can a corresponding PDU collection.

Alternatively, when step 202 performs according to 202a, the step 203 in the present embodiment specifically may include that

203a, described media controller, according to the mapping relations of preset LFU and PDU, search the PDU collection providing a described LFU, the 2nd PDU collection of described 2nd LFU.

It is understandable that, after determining target LFU that service is provided, can be according to the mapping relations of LFU and PDU, determine a PDU collection corresponding for LFU with the oneth, 2nd the 2nd corresponding for LFU PDU collection, such as when determining that target LFU is LFU1, the LFU2 in table 1, may determine that according to the mapping relations in table 2 providing the PDU of this LFU1 to concentrate includes PDU1, PDU2, it is provided that the PDU of LFU2 concentrates and includes PDU3, PDU4.

The mapping relations of LFU Yu PDU such as table 2 below:

LFU1	PDU1 or PDU2
		LFU2	PDU3 or PDU4

203b, a described PDU collection and described 2nd PDU collection are combined according to presetting rule.

It should be noted that, the rule being combined between different types of PDU can be preset in media controller, such as this rule can only be applied in combination with other PDU on same veneer for PDU1, such as the multiple PDU be given in table 2, if PDU1 with PDU3, PDU2 with PDU4 are respectively from two different veneers, after being so combined according to this regular first PDU set and the 2nd PDU collection, the PDU obtained integrates as PDU1 and PDU3, PDU2 and PDU3, PDU2 and PDU4.

In some embodiments of the invention, as the most corresponding LFU of described VDU, the most described target LFU is a LFU, and a LFU can be provided by any one in multiple PDU with identical function.

Alternatively, the step 203 in the present embodiment specifically may include that

203b, described media controller, according to the mapping relations of preset LFU and PDU collection, search the PDU collection providing described target LFU.

It is understandable that, after determining target LFU that target VDU is provided, can be according to the mapping relations of LFU and PDU collection, determine the PDU collection that described target LFU is corresponding, such as when determining that target LFU is the LFU1 in table 1, may determine that according to the mapping relations in table 2 providing the PDU of this LFU1 to concentrate includes PDU1, PDU2, PDU3 and PDU4.

Alternatively, when step 203 specifically performs according to 203b, in the present embodiment, step 204 specifically may include that

204c, acquisition PDU concentrate the load status information that each PDU sends, and described load condition is used for indicating each PDU current loads value.

Wherein, media controller can obtain the load value of each PDU from the load status information that PDU concentrates each PDU to send.

Such as table 5 below, represent that PDU concentrates the load value size of each PDU

Physical equipment unit	Load value
		PDU1	53
PDU2	89
		PDU3	77
PDU4	41

204d, concentrate the load value of each PDU according to described PDU, concentrate from described PDU and choose the minimum PDU of load value as a described PDU.

As table 5 understands, choose the minimum PDU4 of PDU concentrated load value as a PDU.

It should be noted that, described media controller obtains PDU and concentrates the load value mode of each PDU, instruction can be sent by described media controller to each PDU, make PDU return the information comprising load value, it is also possible to be periodically the information comprising load value actively to be reported media controller by PDU.

In some embodiments of the invention, after step 203, it is also possible to include step 204 and step 205:

204, obtaining the load status information that PDU concentrates each PDU to send, described load condition is used for indicating each PDU current loads value.

Such as table 4 below, represent that a PDU collection and the 2nd PDU concentrate the load value size of each PDU

PDU combination of sets	Load value
		PDU1 and PDU4	53
PDU2 and PDU3	89
		PDU2 and PDU3	68

205, concentrate the load value of each PDU according to described PDU, concentrate from described PDU and choose the minimum PDU of load value as a described PDU.

As table 4 understands, the load value of PDU1 and PDU4 combination is minimum, therefore chooses minimum PDU1 and PDU4 of PDU concentrated load value as a PDU, can avoid because the excessive destination service causing realizing of PDU combination load is unstable.

It should be noted that, described media controller obtains PDU and concentrates the load value mode of each PDU, instruction can be sent by described media controller to each PDU, make PDU return the information comprising load value, it is also possible to be periodically the information comprising load value actively to be reported media controller by PDU.Wherein, this load status information can be stored to the pressure of bus, CPU load etc. in including.

In some embodiments of the invention, after step 205, it is also possible to include step 206 and step 207:

206, the first information that a described PDU sends, the state that the described first information currently runs are obtained for indicating a described PDU.

Wherein, the running status of self periodically or aperiodically can be fed back to media controller by the oneth PDU, specifically can send the first information to media controller, this first information is for indicating running status current for first object PDU, and this running status includes normal and exception two kinds.

It should be noted that this PDU can be actively to send this first information, it is also possible to be when receiving the instruction that media controller issues, passive this first information of transmission, it is not construed as limiting the most herein.

207, when determining a described PDU operation exception according to the described first information, concentrate from described PDU and choose the 2nd PDU, described 2nd PDU is that described PDU concentrates in addition to a described PDU, and the PDU, described 2nd PDU of load value minimum are used for providing described target LFU.

It is understandable that, when the first information that a PDU sends indicates a duty current for PDU for time abnormal, this media controller is concentrated from PDU and is chosen in addition to a PDU, and the PDU of load value minimum is used for providing described target LFU as the 2nd PDU, the 2nd PDU.Such as, when step 203 performs according to 203a, PDU2 and PDU3 can be chosen as the 2nd PDU, when step 203 performs according to 203b, PDU1 can be chosen as the 2nd PDU.

It should be noted that, in the present embodiment, when determining that a PDU occurs abnormal, media controller chooses the minimum PDU of load value as the 2nd PDU, so can play and both avoid target PDU run-time error to cause providing service, can avoid again because PDU load value is too big, and the problem causing service instability.In actual applications, it is also possible to choose PDU and concentrate other PDU as the 2nd PDU, be not construed as limiting the most herein.

Alternatively, before the step 202 of the embodiment of the present invention, this media controller can also obtain the 3rd information, and described 3rd information carries the mapping relations of VDU Yu LFU.Such as, from external storage, copy or the data message of the download package mapping relations containing this VDU and LFU, i.e. install VDU service.
