Managed service is a service provider that constructs an IT operation environment for enterprise customers and operates and maintains the IT operation environment. Customers using these managed services can save on initial setup costs and save manpower and costs to maintain their IT operating environment through service providers.

The existing managed service installs the customer premises equipment (CPE) at a place designated by the customer, sets the IT operating environment through the customer premises equipment, and provides the managed service to the customer do. However, such a customer-specific CPE is not only expensive, but also has difficulty in remotely managing the CPE and controlling the service.

Accordingly, a virtualization-based managed service has been developed in which a customer service CPE is constructed in a management node (for example, a cloud center) and the managed service is provided to the customer through the CPE. Through this, it is possible to reduce the service provision and operation cost by sharing one CPE device built in the management node by several customers.

However, when the customer service CPE is located in the management node, the management node and the customer company use the internet network, which poses a security threat in the transmission path section. In addition, since all packets generated by the customer are transmitted to the external network via the management node, the number of hops on the transmission path increases, thereby causing transmission delay.

The infrastructure manager 200 identifies the detailed functions for realizing the managed service requested by the customer and distributes the detailed functions to the smart CPE 100 and the cloud centers 300 and 400-N. At this time, the infrastructure manager 200 confirms the type of the managed service requested by the customer, and confirms the detailed functions for realizing the service type. Then, the infrastructure manager 200 determines the detailed functions The functions to be mounted on the smart CPE 100 or the cloud center 300 and 400-N, respectively.

In addition, the infrastructure manager 200 checks whether the service requested by the customer is a localized service, and if the localized service is the localized service, the local cloud center 400-N closest to the customer is selected as a service providing cloud center , And some or all of the detailed functions are mounted on the selected local cloud center 400-N. On the other hand, if the service requested by the customer is not a localized service, the infrastructure manager 200 selects the central cloud center 300 as a service providing cloud center, and the selected central cloud center 300 Some or all of them.

2 is a diagram illustrating a configuration of an infrastructure manager according to an embodiment of the present invention.

2, the infrastructure manager 200 according to an exemplary embodiment of the present invention includes a service acceptance unit 210, a storage unit 220, a profile management unit 230, a center selection unit 240, (250) and a status monitoring unit (260), and these components may be implemented in hardware or software, or a combination of hardware and software.

The infrastructure manager 200 may include a memory and one or more processors and includes a service acceptance unit 210, a storage unit 220, a profile management unit 230, a center selection unit 240, a function setting unit 250, And the state monitoring unit 260 may be stored in the memory and implemented in the form of a program executed by the one or more processors. In addition, the components of the infrastructure manager 200 may be implemented in a separate server or device, or may be installed in a specific cloud center 300 or 400-N or a server.

The service acceptance unit 210 receives a service subscription from a customer and performs a service contract with a customer. The service accepting unit 210 communicates with the terminal owned by the customer and stores the information such as the name of the customer (or company name), the telephone number of the customer, the identification information of the smart CPE 100 owned by the customer, Service subscription information including information and SLA ratings can be received from the customer. In addition, the service acceptance unit 210 may provide the customer's service profile generated by the profile management unit 230 as a customer, and may receive a service agreement, a service change, or an idle service from the customer.

The storage unit 220 is a storage unit such as a database, a disk unit, a memory, and the like. The storage unit 220 stores a service profile for each customer and stores location information for each of the cloud centers 300 and 400-N.

In addition, the storage unit 220 stores the SLA grade concluded with the customer for each customer. In addition, the storage unit 220 stores a number of detailed functions required for the managed service by the managed service type. The storage unit 220 may store the VNF image as a detailed function. In addition, the storage unit 220 may store a detailed function ratio to be installed in the smart CPE 100 according to the SLA level. As the SLA rating increases, the detailed function ratio to be loaded on the CPE 100 is recorded high and stored in the storage unit 220. [

The profile management unit 230 generates a service profile of a customer and stores the service profile in the storage unit 220 or changes the service profile of the customer. Specifically, the profile management unit 230 identifies the type of the managed service in the service subscription information, extracts a plurality of detailed functions corresponding to the service type from the storage unit 220, and then determines the SLA rating of the customer, And the functions to be installed in the smart CPE 100 and the cloud center 300 and 400-N, respectively. At this time, the profile managing unit 230 can increase the number of detailed functions mounted on the smart CPE 100 as the higher the SLA grade service quality is required. On the other hand, if the SLA rating is low, the profile management unit 230 can reduce the number of detailed functions mounted on the smart CPE 100. In addition, the profile management unit 230 functions as a function to the smart CPE 100, such as a detailed function (e.g., a mobile private branch exchange, a P-LTE, etc.) that is sensitive to transmission delays and requires a high quality of service (E.g., DPI (Deep Packet Inspection), IPS (Intrusion Prevention System), IDS (Intrusion Detection System), and the like) to the smart CPE 100 The profile management unit 230 may classify the extracted functions as functions to be installed in the smart CPE 100. The characteristics of each detailed function, the amount of traffic generated by the detailed functions, The required QoS class and whether or not security is required are set by the administrator in advance.

At this time, the profile management unit 230 confirms the detailed function mounting ratio of the smart CPE 100 corresponding to the customer SLA class in the storage unit 220, and stores the functions corresponding to the number corresponding to the detailed function mounting ratio The smart CPE 100 may be provided with a function to load the selected detailed functions in the cloud center 300 or 400-N. The profile management unit 230 may classify the detailed functions by adjusting the first-classified detailed functions in consideration of the service security, the QoS, and the traffic amount among the first-classified functions. That is, when the detailed functions (e.g., firewall, DRM, etc.) requiring security are classified as being mounted on the cloud centers 300 and 400-N among the first-classified detailed functions, (I.e., a detailed function requiring security) to the smart CPE 100. [ In addition, the profile management unit 230 has a function of mounting a detailed function (e.g., a mobile private branch exchange, a P-LTE or the like) that is sensitive to a transmission delay and requires high QoS guarantee to the cloud centers 300 and 400-N It is possible to adjust the detailed function to the function of mounting the smart CPE 100 on the smart CPE 100. In addition, the profile management unit 230 may include a detailed function that causes a large amount of traffic to be installed in the cloud center. If the primary function is classified, the profile management unit 230 may adjust the detailed function to be installed in the smart CPE 100.

As another embodiment, the profile management unit 230 may load a function requiring security among a plurality of extracted detailed functions in the smart CPE 100. The function that is sensitive to a transmission delay and requests a high QoS is a smart CPE The smart CPE 100 is classified into a function to be loaded on the smart CPE 100 and a function to cause a large amount of traffic to be loaded on the smart CPE 100. Then, Or the functions to be mounted on the cloud centers 300 and 400-N. At this time, the profile management unit 230 confirms the functional loading ratio of the smart CPE corresponding to the SLA rating of the customer in the storage unit 220, and stores a part or all of the detailed functions not classified to match the functional loading ratio As a function to be loaded on the smart CPE 100, the remaining functions can be ultimately classified into functions to be mounted on the cloud centers 300 and 400-N.

In addition, the profile management unit 230 determines whether or not to perform redundancy based on the SLA rating of the customer. That is, the profile management unit 230 checks whether the SLA rating of the customer is equal to or higher than a certain grade, and determines whether to support the redundancy if the grade is higher than a certain grade.

On the other hand, the profile management unit 230 requests the center selection unit 240 to select a cloud center, identifies the cloud center identification information selected by the center selection unit 240, detailed function information to be installed in the cloud center, A service profile including detailed function information, customer information (e.g., customer name or company name, address, etc.), and information on whether or not to support redundancy, and stores the generated service profile in the storage unit 220.

The center selection unit 240 identifies the type of the managed service included in the service subscription information, determines whether the service requested by the customer is a region-based service based on the managed service type, The local cloud center 400-N or the central cloud center 300 is selected as a cloud center to provide services. At this time, if the managed service requested by the customer is a region-based service (for example, a local telephone service), the center selecting unit 240 confirms the location of the customer, and the local cloud center 400- N) as a cloud center to provide services. The area-based service is a service limited to a specific area to which the service is to be used. Examples of the area-based service include a local telephone service and a local private network service. The service type list corresponding to the area- And stored in advance. On the other hand, if the center selecting unit 240 is not the service area based service requested by the customer, the center selecting unit 240 selects the central cloud center 300 as a cloud center to provide the service.

When the customer agrees to conclude the contract, the function setting unit 250 loads some of the detailed functions required for the management service requested by the customer into the smart CPE 100 based on the customer's service profile stored in the storage unit 220 And the remaining detailed functions are loaded on the cloud center 300, 400-N. Specifically, in the service profile of the customer, the function setting unit 250 may include information on detailed functions to be loaded on the smart CPE 100, information on functions to be mounted on the cloud center, information on whether to support redundancy, Identify the identity of the cloud center you provide. In addition, the function setting unit 250 transmits data (for example, VNF image or VNF setting information) about the detailed functions to be mounted on the smart CPE 100 to the smart CPE 100, ). The function setting unit 250 recognizes the cloud centers 300 and 400-N corresponding to the identification information of the cloud center and transmits data (e.g., VNF image or VNF setting information) of the detailed functions to be mounted on the cloud center To the recognized cloud centers 300 and 400-N, and controls the corresponding functions to be mounted on the cloud centers 300 and 400-N. At this time, the function setting unit 250 requests one or more virtual machine assignments for realizing the detailed functions to the recognized cloud center 300 and 400-N, and allows the detailed functions to be loaded through the virtual machine .

The function setting unit 250 may also mount the detailed functions loaded on the smart CPE 100 in the recognized cloud center 300 and 400-N when duplication support information is recorded in the customer's service profile, Thereby duplicating the detailed functions mounted on the smart CPE 100. At this time, the function setting unit 250 controls the functions installed in the smart CPE 100 to operate in the active mode, and controls the detailed functions of the smart CPE 100 installed in the cloud center to operate in the standby mode. Accordingly, when a failure occurs in any one of the detailed functions of the smart CPE 100, detailed functions of the cloud center 300 and 400-N corresponding to the failed function operate in the active mode in the standby mode, Provide managed services to customers.

The state monitoring unit 260 continuously monitors the operation state of each detailed function mounted on the smart CPE 100 and the operation state of each possibility mounted on the cloud center. That is, the status monitoring unit 260 continuously checks the state of each of the detailed functions installed in the smart CPE 100 and the cloud center to determine whether a failure has occurred in each detailed function. The state monitoring unit 260 notifies the operator or the customer of the occurrence of a failure when a failure occurs in a specific detailed function.

3 is a flowchart illustrating a method for providing a managed service to a customer based on a managed service characteristic and an SLA in a managed service system according to an exemplary embodiment of the present invention.

3, the customer accesses the infrastructure manager 200 using his or her own terminal, and then displays the name of the customer (or company name), the telephone number of the customer, and the number of the smart CPE 100 owned by the customer Identification information, customer location information, managed service type information, and service subscription information including the SLA rating to the infrastructure manager 200 (S301).

Then, the service acceptance unit 210 of the infrastructure manager 200 receives the service subscription information from the customer, and the profile management unit 230 confirms the managed service type and the SLA rating included in the subscription information (S303). Examples of the managed service type include an internal computerized management service, a video conference service, a customer management service, and a shopping mall service.

Then, the profile management unit 230 extracts the detailed functions corresponding to the managed service type from the storage unit 220 and confirms the detailed functions required for the service requested by the customer (S305). Next, the profile management unit 230 loads a part of the detailed functions into the smart CPE 100 in consideration of the SLA rating of the customer and the characteristics of each detailed function (i.e., the amount of traffic, QoS grade, security necessity, etc.) (S307), and the remaining functions are classified into functions to be loaded on the cloud centers 300 and 400-N. Specific embodiments in which the profile management unit 230 classifies the detailed functions will be described later with reference to FIGS. 4 and 5. FIG.

Then, the profile management unit 230 confirms the SLA rating of the customer, and determines whether or not to support redundancy of the detailed function mounted on the smart CPE 100 (S309). That is, the profile management unit 230 determines whether the SLA rating of the customer is equal to or higher than a set grade. If the SLA rating of the customer is lower than a predetermined grade, the profile management unit 230 determines that the customer does not support the redundancy. It is determined to support redundancy.

Next, the profile management unit 230 requests the center selection unit 240 to select a cloud center. Then, the center selection unit 240 identifies the managed service type included in the service subscription information, determines whether the service requested by the customer is a region-based service based on the managed service type, And selects the nearest local cloud center 400-N or the central cloud center 300 as a cloud center to provide the service (S311). At this time, if the managed service requested by the customer is a region-based service (e.g., a local telephone service or the like), the center selecting unit 240 confirms the location of the customer and stores the location of the customer in the cloud center And selects a local cloud center 400-N located nearest to the customer as a cloud center to provide the service. On the other hand, if the center selecting unit 240 is not the service area based service requested by the customer, the central cloud center 300 is selected as the cloud center to provide the service. In the description with reference to FIG. 3, it is explained that the center selecting unit 240 selects the central cloud center 300 as a service center.

When the selection of the cloud center is completed in the center selection unit 240, the profile management unit 230 receives the cloud center identification information selected by the center selection unit 240, information of the detailed functions to be installed in the cloud center, A service profile including information on functions, customer information (e.g., customer name or company name, address, etc.), information on whether to support redundancy, and SLA rating information is generated and stored in the storage unit 220 (S313).

Then, the service acceptance unit 210 provides the generated service profile of the customer to the customer and requests final approval of the managed service from the customer (S315).

Then, after reviewing the service profile, the customer transmits a consent, rejection, or service change request to the managed service to the infrastructure manager 200 (S317). In the description with reference to FIG. 3, it is described that the customer agrees with the managed service.

If the customer declines the service, the service acceptance unit 210 of the infrastructure manager 200 deletes the customer service profile stored in the storage unit 220, and may terminate the procedure thereafter. On the other hand, when the customer requests the service change, the profile management unit 230 of the infrastructure manager 200 changes the service profile of the customer in accordance with the change, and the service acceptance unit 210 transmits the changed service profile of the customer to the customer To request the customer's final consent.

When the infrastructure manager 200 receives the service agreement from the customer, the function setting unit 250 obtains information on the detailed functions to be mounted on the smart CPE 100, Information on detailed functions to be mounted on the cloud center 300, information on whether or not to support redundancy, and identification information of the central cloud center 300 providing the service. Then, the function setting unit 250 recognizes the central cloud center 300 corresponding to the cloud center identification information, and transmits data (e.g., VNF image or VNF setting information) of the detailed functions to be mounted on the central cloud center 300 To the central cloud center 300, and controls the corresponding detailed functions to be loaded on the central cloud center 300 (S319). At this time, the function setting unit 250 requests the central cloud center 300 to allocate one or more virtual machines for realizing the detailed functions, and loads the detailed functions into the central cloud center 300 through the virtual machine .

Then, the function setting unit 250 transmits data (e.g., VNF image or VNF setting information) about the detailed functions to be mounted by the smart CPE 100 to the smart CPE 100, (S321).

When the detailed functions required for the managed service requested by the customer are distributed and installed in the smart CPE 100 and the central cloud center 300, the detailed functions are linked with each other to provide the managed service to the customer.

The function setting unit 250 loads the detailed functions to be loaded on the smart CPE 100 into the central cloud center 300 and transmits the detailed functions to the smart CPE 100, To duplicate the functions installed in the system. At this time, the function setting unit 250 controls the detailed functions mounted on the smart CPE 100 to operate in the active mode, and controls the duplicated detailed functions to operate in the standby mode in the central cloud center 300. Accordingly, when a failure occurs in one of the detailed functions of the smart CPE 100, the detailed function of the central cloud center 300 corresponding to the detailed function of the failure operates in the active mode in the standby mode, To the customer.

When each of the detailed functions is installed in one of the central cloud center 300 and the smart CPE 100, the status monitoring unit 260 monitors the operation status of each detailed function installed in the smart CPE 100, The operation state of each of the possibilities mounted on the cloud center 300 is continuously motorized to monitor the failure. When a failure occurs in a specific function, the status monitoring unit 260 notifies the operator or the customer of the failure.

4 is a flowchart illustrating a method of classifying detailed functions required for a managed service in a managed service system according to an embodiment of the present invention.

Referring to FIG. 4, the profile management unit 230 identifies the managed service type in the service subscription information of the customer, and extracts a plurality of detailed functions corresponding to the managed service type in the storage unit 220 (S401).

Then, the profile management unit 230 confirms the customer SLA rating included in the service subscription information (S403). And the profile management unit 230 checks the SLA rating of the customer in the storage unit 220 by the profile management unit 230, based on the functional placement ratio of the smart CPE 100 corresponding to the customer SLA rating. As the SLA rating is higher, the detailed function ratio to be loaded on the CPE 100 is recorded higher and stored in the storage unit 220.

Then, the profile managing unit 230 arbitrarily selects the detailed functions corresponding to the number corresponding to the function loading ratio among the extracted detailed functions, loads the selected functions into the smart CPE 100, The detailed functions are classified into functions to be mounted on the cloud centers 300 and 400-N (S405). For example, the profile management unit 230 arbitrarily selects five of the detailed functions when the functional coverage ratio of the smart CPE corresponding to the SLA class is 50% and the extracted detailed functions are 10, It can be classified as a function to be mounted, and the remaining five functions can be classified as a function to be mounted in the cloud center.

Next, the profile management unit 230 determines whether or not functions (for example, a firewall, a CRM, and the like) requiring service security are firstly classified as being mounted on the cloud centers 300 and 400-N among the first- (S407). If it is determined that the detailed functions requiring service security are installed in the cloud centers 300 and 400-N as a result of the determination, the detailed functions are adjusted to functions to be mounted on the smart CPE 100 (S409). That is, if the detailed function requiring service security is classified as being mounted on the cloud center 300 or 400-N, the profile management unit 230 may divide the detailed function into the smart CPE 100 Adjust it with the function to be mounted.

Next, the profile management unit 230 loads a detailed function (for example, a mobile private branch exchange, a P-LTE, or the like), which is sensitive to a transmission delay, (S411). If it is determined that a detailed function requiring a high QoS level equal to or higher than the critical grade is installed in the cloud center, the function is adjusted to a function of loading the smart CPE 100 (S413). In other words, when detailed functions requiring high QoS guarantee are mounted in the cloud centers 300 and 400-N, transmission delays due to an increase in the number of hops are generated, and due to the characteristics of the cloud center, It can be difficult to receive. Accordingly, the profile management unit 230 adjusts the function to be installed in the smart CPE 100 when the detailed function requiring a guarantee of a QoS higher than the critical grade is firstly classified as being installed in the cloud center

Then, the profile management unit 230 determines whether the detailed functions that cause a large amount of traffic in excess of the threshold traffic amount set in advance are first classified by the functions installed in the cloud center (S415) If it is determined that the function is installed in the cloud center 300 or 400-N, the detailed function is adjusted to a function mounted on the smart CPE 100 (S417). That is, the profile management unit 230 adjusts the detailed function to be installed in the smart CPE 100 so that the smart CPE 100 dedicated to the customer processes the detailed function that causes a large amount of traffic.

On the other hand, the profile management unit 230 does not load the detailed functions requiring security to the cloud centers 300 and 400-N, and the detailed functions that require QoS higher than the critical grade are not installed in the cloud centers 300 and 400-N If it is determined that the detailed functions that cause a larger amount of traffic than the critical traffic volume are not yet established in the cloud centers 300 and 400-N, the adjustment of the first-classified detailed functions is not performed (S419).

5 is a flowchart illustrating a method of classifying functions required for customer service in a managed service system according to another embodiment of the present invention.

Referring to FIG. 5, the profile management unit 230 identifies a managed service type in the service subscription information of the customer, and extracts a plurality of detailed functions corresponding to the managed service type from the storage unit 220 (S501).

Then, the profile management unit 230 determines whether there is a function requiring service security among the extracted detailed functions, and classifies the detailed function that requires service security as a function to be loaded on the smart CPE 100 (S503 ).

If there is a function that causes a larger amount of traffic than the critical traffic amount among the unclassified functions, the profile management unit 230 classifies the detailed function as a function to be loaded on the smart CPE 100 (S505) . Then, the profile management unit 230 determines whether there is a function that is sensitive to a transmission delay and is required to guarantee a higher QoS than a threshold level among the unclassified functions, and if the function exists, the profile management unit 230 transmits the detailed function to the smart CPE 100, (S507).

Next, the profile management unit 230 confirms the SLA rating of the customer (S509), and confirms the functional placement ratio of the smart CPE corresponding to the SLA rating in the storage unit 220. [ The profile management unit 230 is a function that loads some or all of the detailed functions not classified to fit the function loading ratio into the smart CPE 100 and transmits the remaining functions to the cloud centers 300 and 400- Finally, the function to be mounted is classified (S511). For example, if the function placement ratio of the smart CPE corresponding to the SLA class is 80% and five unclassified detailed functions remain, the profile management unit 230 randomly selects four of the detailed functions, And the remaining one detailed function may be classified as a function to be mounted on the cloud center.

As described above, in the managed service system according to the embodiment of the present invention, a detailed function that requires security or assures a high QoS or generates a large amount of traffic is based on the SLA rating of the customer, The detailed functions that are installed in the smart CPE 100 and require no security, low QoS grade, or low traffic volume are mounted in the cloud centers 300 and 400-N, thereby optimizing them according to the customer's managed service environment Managed services. In addition, if the managed service is a region-based service, the managed service system according to the embodiment of the present invention provides the managed service through the local cloud center 400-N closest to the customer, do. In addition, the managed service system according to the embodiment of the present invention may be configured such that the detailed functions mounted on the smart CPE 100 are installed in the cloud centers 300 and 400-N and the detailed functions of the smart CPE 100 are duplicated, Thereby improving the availability of the smart CPE 100.
