1 is a schematic block diagram of a global network slice management system according to an embodiment of the present invention.

As shown in FIG. 1, the identification system registration unit 100 generates and transmits a local network slice identification system through grouping of attribute information constituting the local network slice, and stores the transmitted local network slice identification system. An identification system management unit 200 integrating the local network slice identification system of the network and storing the integrated network slice identification system as a global network slice identification system; And an identification system update unit 300 for updating the stored local network slice identification system and the global network slice identification system. Here, a local network slice refers to a physical or virtual network created for performing a specific service on a local network domain, and the local network slice is one or more nodes included in the network, an interface per node, and a link connected to the interface. It can be configured as.

The identification system registration unit 100 generates the local network slice identification system by grouping the attribute information constituting the local network slice.

More specifically, the identification system registration unit 100 collects attribute information constituting a local network slice generated for performing a specific service on a local network domain, and generates a local network slice identification scheme through grouping of the collected attribute information. Done. That is, the identification system registration unit 100 includes attribute information including a name of a local network for the corresponding local network, a name of one or more physical or virtual nodes included in the network, a name of an interface for each node, and a name of a link connected to the interface. In this way, the local network slice identification system is generated by performing grouping through the sequential arrangement of the collected attribute information. Here, in the case of the local network slice identification scheme, it has the structure of [local network {:: node {: interface: link}}], and after the name of the local network, the number of nodes and interfaces included in the local network slice in the {} symbol. As many times as it consists of at least one set of {}. For example, in a local network called 'KREONET', a local network slice is composed of two virtual nodes 'V-Node1' and 'V-Node2', and the 'V-Node1' node is configured with a 'V-IF1' interface. The 'V-IF1' interface is connected to the link 'V-Link1', and the 'V-IF2' interface of the 'V-Node2' is connected through the link 'V-Link1' and the 'V- If the IF2 'interface is connected to the' V-Node2 'node, in the case of a grouped local network slice identification scheme,' [KREONET :: V-Node1: V-IF1: V-Link1 :: V-Node2: V- ' IF2: V-Link1] '.

Furthermore, the identification system registration unit 100 transmits the generated local network slice identification system to the identification system management unit 200 to request registration.

More specifically, the identification system registration unit 100 transmits the local network slice identification system generated as described above to the identification system management unit 200 to request registration, and identifies the local network slice abbreviation for the transmitted local network slice identification system. The system is received from the identification system management unit 200 to map and manage the local network slice. On the other hand, the identification system registration unit 100 when a plurality of local network slice identification systems delivered to the identification system management unit 200 is integrated, and managed by a global network slice shortened identification system, from the identification system management unit 200 to the global network A short identification scheme for a slice identification scheme is received, and each local network slice constituting the global network slice identification scheme and the received global network short identification scheme are mapped and managed. In this regard, when the newly registered local network slice identification system is newly registered, the identification system registration unit 100 transmits the local network slice address and the grouped local network slice identification system to the identification system management unit 200. On the other hand, the identification system registration unit 100, if a registered local network slice identification system is changed, or if each local network slice identification system included in the global network slice identification system is changed or deleted, the corresponding local network slice shortened identification system Alternatively, by transmitting the changed local network slice identification system together with the global network slice reduction identification system to the identification system update unit 300, the identification system update unit 300 stores the global information stored in the identification system management unit 200 based on the transmitted information. Allow network identification to be updated.

The identification system management unit 200 stores a local network slice identification system transmitted from the identification system registration unit 100.

More specifically, the identification system management unit 200 stores the local network slice identification system transmitted from the identification system registration unit 100 and identifies local network slices stored using, for example, MD5 hash algorithm of RFC1321, which is an international standard of the IETF. Create a short identification system for the system. In addition, the identification system management unit 200 maps and stores the local network slice shortened identification system and then transfers the local network slice shortened identification system to the corresponding local network slice through the identification system register 100, thereby allowing the identification system register 100 to identify the local network slice shortened identification. You can manage the scheme by mapping it to the local network slice. On the other hand, the identification system management unit 200 generates and identifies a shortened identification system for the updated local network slice identification system, as described above, when the local network slice identification system previously registered by the identification system update unit 300 is updated. Through the system registration unit 100 is delivered to the local network slice.

In addition, the identification system management unit 200 generates a global network slice identification system by integrating the local network slice identification system.

More specifically, the identification system management unit 200 when the contraction identification system of the local network slice identification system transmitted from the identification system registration unit 100 matches the contraction identification system mapped with the registered local network slice identification system, Each local network slice identification system is integrated and stored as a global network slice identification system. For example, when a local network slice identification system such as '[NEW-NET :: V-Node1: V-IF1: V-Link1]' is newly created and registered, it is already known as '[KREONET :: V-Node1: V-IF1'. If there is a previously registered local network slice sharing the same shorthand scheme as the newly registered local network slice, such as: V-Link1 :: V-Node2: V-IF2: V-Link1] ' By connecting and integrating the network identification system, '[KREONET :: V-Node1: V-IF1: V-Link1 :: V-Node2: V-IF2: V-Link1] [NEW-NET :: V-Node1: V-IF1: V-Link1] 'will be stored and managed by the global network slice identification system. On the other hand, in the case of the integrated global network identification system as described above, as the local network slices are added, they are continuously interconnected and lengthened, resulting in poor scalability and difficulty in management. Therefore, the identification system management unit 200 generates a short identification system for the integrated global network slice identification system using the MD5 hash algorithm of RFC1321, which is an international standard of the IETF, and generates the generated global network slice short identification system. Are stored by mapping each other with the stored global network slice identification system. Subsequently, the identification system management unit 200 transmits the global network slice reduction identification system to each local network slice constituting the global network slice identification system through the identification system registration unit 100, thereby causing the identification system registration unit 100. Each local network slice constituting the global network slice identification system and the global network slice shortened identification system may be mapped and managed. On the other hand, the identification system management unit 200 generates a shortened identification system for the updated global network slice identification system, as described above, even when the global network slice identification system registered by the identification system update unit 300 is updated. The identification system registration unit 100 delivers the updated global network slice identification system to each local network slice.

The identification system update unit 300 updates the local network slice identification system or the global network slice identification system that is registered in the identification system management unit 200.

More specifically, the identification system updating unit 300 detects a change state of the local network slice identification system pre-registered in the identification system registration unit 100 or of each local network slice identification system included in the global network slice identification system. When the change or deletion state is detected, the local network slice identification system or the local network slice identification system is changed from the identification system registration unit 100. Based on this, the identification system updater 300 extracts the local network slice identification system mapped to the identification system management unit 200 based on the received shortened identification system and stores the extracted local network slice identification system in the changed local network. Update to reflect network slice identification. Meanwhile, when a specific local network slice identification system included in the global network slice identification system is changed or deleted, the specific local network slice mapped and stored in the identification system management unit 200 based on the shortened identification system for the specific local network slice. After extracting and updating the identification system, the global network slice identification system mapped to the identification system management unit 200 is stored and extracted based on the global network slice shortening identification system, thereby reflecting the update status.

Hereinafter, with reference to FIG. 2, a more detailed configuration of the identification system registration unit 100 (identification system registration device) according to an embodiment of the present invention will be described.

That is, the identification system registration unit 100 includes an attribute information collection module 110 for collecting attribute information constituting the local network slice; An identification system generation module 120 for generating a local network slice identification system; And an identification scheme registration module 130 for registering the generated local network slice identification scheme.

More specifically, the attribute information collection module 110 includes a name of a local network for the corresponding local network, a name of one or more physical or virtual nodes included in the network, a name of an interface for each node, and a name of a link connected to the interface. Collect attribute information.

The identification system generation module 120 generates a local network slice identification system through grouping of the collected attribute information.

More specifically, the identification system generation module 120 includes a name of a local network for the corresponding local network, a name of one or more physical or virtual nodes included in the network, a name of an interface for each node, and a name of a link connected to the interface. A local network slice identification system is generated by performing grouping through a sequence of attribute information. Here, in the case of the local network slice identification scheme, it has the structure of [local network {:: node {: interface: link}}], and after the name of the local network, the number of nodes and interfaces included in the local network slice in the {} symbol. As many times as it consists of at least one set of {}. For example, in a local network called 'KREONET', a local network slice is composed of two virtual nodes 'V-Node1' and 'V-Node2', and the 'V-Node1' node is configured with a 'V-IF1' interface. The 'V-IF1' interface is connected to the link 'V-Link1', and the 'V-IF2' interface of the 'V-Node2' is connected through the link 'V-Link1' and the 'V- If the IF2 'interface is connected to the' V-Node2 'node, in the case of a grouped local network slice identification scheme,' [KREONET :: V-Node1: V-IF1: V-Link1 :: V-Node2: V- ' IF2: V-Link1] '.

The identification system registration module 130 transmits the generated local network slice identification system to the identification system management unit 200 to request registration.

The identification system is received from the identification system management unit 200 to map and manage the local network slice. On the other hand, the identification system registration module 130 is integrated with a plurality of local network slice identification system delivered to the identification system management unit 200, if managed by a global network slice shortened identification system, from the identification system management unit 200 to the global A shortened identification system for the network slice identification system is received, and each local network slice constituting the global network slice identification system and the received global network shortened identification system are mapped and managed. In this regard, when the newly registered local network slice identification system is newly registered, the identification system registration module 130 transmits the local network slice address and the grouped local network slice identification system to the identification system management unit 200.

In addition, the identification system registration module 130 supports updating of a registered local network slice identification system or a global network slice identification system.

More specifically, the identification scheme registration module 130, when the registered local network slice identification scheme is changed, or when each local network slice identification scheme included in the global network slice identification scheme is changed or deleted, the corresponding local network slice By transmitting the changed local network slice identification system together with the shortened identification system or global network sliced shortened identification system to the identification system update unit 300, the identification system update unit 300 based on the information transmitted to the identification system management unit 200 Updates the global network identification system stored in the system.

Hereinafter, a detailed configuration of the identification system management unit 200 according to an embodiment of the present invention will be described with reference to FIG. 3.

That is, the identification system management unit 200 generates an identification system storage module 210 for storing the generated local network slice identification system, and an identification system management for generating and providing a shortened identification system minimized by compressing the stored local network slice identification system. Has a configuration that includes a module 220.

The identification system storage module 210 stores the local network slice identification system transmitted from the identification system registration unit 100.

More specifically, the identification system storage module 210 stores the local network slice identification system transmitted from the identification system registration unit 100, and at this time, the shorthand of the local network slice identification system transmitted from the identification system registration unit 100 is reduced. If the identification scheme matches the abbreviated identification scheme mapped with the registered local network slice identification scheme, each local network slice identification scheme is integrated and stored as a global network slice identification scheme. For example, when a local network slice identification system such as '[NEW-NET :: V-Node1: V-IF1: V-Link1]' is newly created and registered, it is already known as '[KREONET :: V-Node1: V-IF1'. If there is a previously registered local network slice sharing the same shorthand scheme as the newly registered local network slice, such as: V-Link1 :: V-Node2: V-IF2: V-Link1] ' By connecting and integrating the network identification system, '[KREONET :: V-Node1: V-IF1: V-Link1 :: V-Node2: V-IF2: V-Link1] [NEW-NET :: V-Node1: V-IF1: V-Link1] 'will be stored and managed by the global network slice identification system.

In this regard, the identification system management module 220 generates and provides a shortened identification system for the stored local network slice identification system and the global network slice identification system.

More specifically, the identification system management module 220 generates a shortened identification system for the stored local network slice identification system, for example, using the MD5 hash algorithm of RFC1321, which is an international standard of the IETF. In addition, the identification system management module 220 maps and stores the local network slice shortened identification system and then transfers the local network slice shortened to the corresponding local network slice through the identification system register 100, thereby allowing the identification system register 100 to shorten the local network slice. It can be managed by mapping the identification system to the corresponding local network slice. On the other hand, the identification system management module 220 generates an abbreviated identification system for the updated local network slice identification system, as described above, when the local network slice identification system registered by the identification system update unit 300 is updated. Through the identification system registration unit 100 is delivered to the local network slice. In addition, the identification system management module 220 generates a short identification system for the integrated global network slice identification system using the MD5 hash algorithm of RFC1321, which is an international standard of the IETF, and generates the shortened global network slice short identification. The system is mapped to the stored global network slice identification system and stored. Subsequently, the identification system management module 220 transmits the global network slice reduction identification system to each local network slice constituting the global network slice identification system through the identification system registration unit 100, thereby to the identification system registration unit 100. It is possible to map and manage each local network slice constituting the global network slice identification scheme and the global network slice short identification scheme. On the other hand, the identification system management module 220 generates a shortened identification system for the updated global network slice identification system, as described above, even when the global network slice identification system registered by the identification system update unit 300 is updated. Then through the identification system registration unit 100 is delivered to each local network slice constituting the updated global network slice identification system.

Hereinafter, a detailed configuration of the identification system updater 300 according to an embodiment of the present invention will be described with reference to FIG. 4.

In other words, the identification system update unit 300 includes a variation checking module 310 for checking a change state of the local network slice identification system or the global network slice identification system, and a registered local network slice identification system or the global network slice identification system. It has a configuration including an identification system update module 320 for updating.

The change checking module 310 checks the change state of the local network slice identification system or the global network slice identification system which is registered in the identification system registration unit 100.

More specifically, the change checking module 310 detects the change state of the local network slice identification system pre-registered in the identification system registration unit 100 or changes each local network slice identification system included in the global network slice identification system. Alternatively, when the deleted state is detected, the local network slice identification system may be received from the identification system registration unit 100 along with the corresponding local network slice short identification system or the global network slice short identification system.

The identification system update module 320 updates the local network slice identification system or the global network slice identification system stored in the identification system management unit 200.

More specifically, the identification system update module 320 extracts the local network slice identification system mapped to the identification system management unit 200 based on the received short identification system and stores the extracted local network slice identification system in the changed local network. Update to reflect network slice identification. On the other hand, the identification system update module 320, if a specific local network slice identification system included in the global network slice identification system is changed or deleted, to the identification system management unit 200 based on the shortened identification system for the specific local network slice. After extracting and updating the mapped and stored specific local network slice identification system, the updated network state is extracted by mapping the stored global network slice identification system to the identification system management unit 200 based on the global network slice shortened identification system to reflect the update status. .

As described above, according to the global network slice management system according to the present invention, by automatically generating and dynamically updating the end-to-end global network slice identification system using attribute information of the local network slice, Uniquely identify virtualized network resources and entities based on future Internet and cloud computing environments. In addition, by collecting attributes of local network slices to automatically create and shorten local identification schemes and dynamically manage global identification schemes, it is possible to improve the efficiency of comparison and retrieval as well as to identify identical entities. It supports the ability to identify end-to-end global slices that change gradually over time.

Hereinafter, a global network slice management method according to an embodiment of the present invention will be described with reference to FIGS. 5 to 8. Here, the configurations shown in FIGS. 1 to 4 will be described with reference to corresponding reference numerals for convenience of explanation.

First, a method of operating a global network slice management system according to an embodiment of the present invention will be described with reference to FIG. 5.

First, the identification system registration unit 100 generates a local network slice identification system by grouping attribute information constituting a local network slice generated for performing a specific service for each local network domain (S110-S120).

Preferably, the identification scheme registration unit 100 collects attribute information constituting the local network slice generated for performing a specific service on the local network domain, and generates a local network slice identification scheme through grouping of the collected attribute information. Done. That is, the identification system registration unit 100 includes attribute information including a name of a local network for the corresponding local network, a name of one or more physical or virtual nodes included in the network, a name of an interface for each node, and a name of a link connected to the interface. In this way, the local network slice identification system is generated by performing grouping through the sequential arrangement of the collected attribute information. Here, in the case of the local network slice identification scheme, it has the structure of [local network {:: node {: interface: link}}], and after the name of the local network, the number of nodes and interfaces included in the local network slice in the {} symbol. As many times as it consists of at least one set of {}. For example, in a local network called 'KREONET', a local network slice is composed of two virtual nodes 'V-Node1' and 'V-Node2', and the 'V-Node1' node is configured with a 'V-IF1' interface. The 'V-IF1' interface is connected to the link 'V-Link1', and the 'V-IF2' interface of the 'V-Node2' is connected through the link 'V-Link1' and the 'V- If the IF2 'interface is connected to the' V-Node2 'node, in the case of a grouped local network slice identification scheme,' [KREONET :: V-Node1: V-IF1: V-Link1 :: V-Node2: V- ' IF2: V-Link1] '.

Then, the identification system registration unit 100 transmits the generated local network slice identification system to the identification system management unit 200 to request registration (S130).

Preferably, the identification system registration unit 100 transmits the local network slice identification system generated as described above to the identification system management unit 200 to request registration. In this regard, when the newly registered local network slice identification system is newly registered, the identification system registration unit 100 transmits the local network slice address and the grouped local network slice identification system to the identification system management unit 200.

Then, the identification system management unit 200 stores the local network slice identification system transmitted from the identification system registration unit 100, and provides a short identification system for the local network slice identification system (S140-S160).

More specifically, the identification system management unit 200 stores the local network slice identification system transmitted from the identification system registration unit 100 and identifies local network slices stored using, for example, MD5 hash algorithm of RFC1321, which is an international standard of the IETF. Create a short identification system for the system. In addition, the identification system management unit 200 maps and stores the local network slice shortened identification system and then transfers the local network slice shortened identification system to the corresponding local network slice through the identification system register 100, thereby allowing the identification system register 100 to identify the local network slice shortened identification. You can manage the scheme by mapping it to the local network slice.

In addition, the identification system management unit 200 integrates the local network slice identification system to generate and provide a global network slice identification system (S170-S190).

More specifically, the identification system management unit 200 when the contraction identification system of the local network slice identification system transmitted from the identification system registration unit 100 matches the contraction identification system mapped with the registered local network slice identification system, Each local network slice identification system is integrated and stored as a global network slice identification system. For example, when a local network slice identification system such as '[NEW-NET :: V-Node1: V-IF1: V-Link1]' is newly created and registered, it is already known as '[KREONET :: V-Node1: V-IF1'. If there is a previously registered local network slice sharing the same shorthand scheme as the newly registered local network slice, such as: V-Link1 :: V-Node2: V-IF2: V-Link1] ' By connecting and integrating the network identification system, '[KREONET :: V-Node1: V-IF1: V-Link1 :: V-Node2: V-IF2: V-Link1] [NEW-NET :: V-Node1: V-IF1: V-Link1] 'will be stored and managed by the global network slice identification system. On the other hand, in the case of the integrated global network identification system as described above, as the local network slices are added, they are continuously interconnected and lengthened, resulting in poor scalability and difficulty in management. Therefore, the identification system management unit 200 generates a short identification system for the integrated global network slice identification system using the MD5 hash algorithm of RFC1321, which is an international standard of the IETF, and generates the generated global network slice short identification system. Are stored by mapping each other with the stored global network slice identification system. Subsequently, the identification system management unit 200 transmits the global network slice reduction identification system to each local network slice constituting the global network slice identification system through the identification system registration unit 100, thereby causing the identification system registration unit 100. Each local network slice constituting the global network slice identification system and the global network slice shortened identification system may be mapped and managed.

Then, the identification system update unit 300 updates the local network slice identification system or the global network slice identification system that is registered in the identification system management unit 200 (S200-S220).

Preferably, the identification system updating unit 300 detects a change state of the local network slice identification system pre-registered in the identification system registration unit 100 or of each local network slice identification system included in the global network slice identification system. When the change or deletion state is detected, the local network slice identification system or the local network slice identification system is changed from the identification system registration unit 100. Based on this, the identification system updater 300 extracts the local network slice identification system mapped to the identification system management unit 200 based on the received shortened identification system and stores the extracted local network slice identification system in the changed local network. Update to reflect network slice identification. Meanwhile, when a specific local network slice identification system included in the global network slice identification system is changed or deleted, the specific local network slice mapped and stored in the identification system management unit 200 based on the shortened identification system for the specific local network slice. After extracting and updating the identification system, the global network slice identification system mapped to the identification system management unit 200 is stored and extracted based on the global network slice shortening identification system, thereby reflecting the update status.

Thereafter, the identification system management unit 200 generates and provides a shortened identification system for the updated local network slice identification system or the global network slice identification system (S230-S240).

Preferably, the identification system management unit 200 generates a shortened identification system for the updated local network slice identification system as described above when the local network slice identification system previously registered by the identification system update unit 300 is updated. It is delivered to the local network slice through the identification system registration unit 100. On the other hand, the identification system management unit 200 generates a shortened identification system for the updated global network slice identification system, as described above, even when the global network slice identification system registered by the identification system update unit 300 is updated. The identification system registration unit 100 delivers the updated global network slice identification system to each local network slice.

Hereinafter, an operation method of the identification system registration unit 100 (identification system registration device) will be described with reference to FIG. 6.

First, the attribute information collection module 110 includes an attribute including a name of a local network for a corresponding local network, a name of one or more physical or virtual nodes included in the network, a name of an interface for each node, and a name of a link connected to the interface. Information is collected (S310).

The identification system creation module 120 then includes the name of the local network for the local network, the name of one or more physical or virtual nodes included in the network, the name of the interface for each node, and the name of the link connected to the interface. Grouping through the sequential arrangement of the attribute information is generated to generate a local network slice identification system (S320).

Then, the identification system registration module 130 transfers the generated local network slice identification system to the identification system management unit 200 to request registration, and identifies a local network slice shortening identification system for the delivered local network slice identification system. Received from the system management unit 200 is mapped to the local network slice to manage. On the other hand, the identification system registration module 130 is integrated with a plurality of local network slice identification system delivered to the identification system management unit 200, if managed by a global network slice shortened identification system, from the identification system management unit 200 to the global A shortened identification system for the network slice identification system is received, and each local network slice constituting the global network slice identification system and the received global network shortened identification system are mapped and managed (S330-S340).

Next, when the identification system registration module 130 changes the registered local network slice identification scheme or changes or deletes each local network slice identification scheme included in the global network slice identification scheme, the local network slice abbreviation is reduced. By transmitting the changed local network slice identification system together with the identification system or the global network slice shortened identification system to the identification system update unit 300, the identification system update unit 300 to the identification system management unit 200 based on the transmitted information. It is possible to update the stored global network identification system (S350-S360).

Subsequently, the identification system registration module 130 receives the abbreviated identification system for the updated local network slice identification system from the identification system management unit 200, maps it to the corresponding local network slice, and manages the updated global network slice identification system. When the shortened ID scheme is received, each local network slice constituting the global network slice ID scheme and the received global network shortened ID scheme are mapped and managed (S370).

Hereinafter, an operation method of the identification system management unit 100 (identification system management apparatus) will be described with reference to FIG. 7.

Then, the identification system management module 220 generates a shortened identification system for the stored local network slice identification system using, for example, the MD5 hash algorithm of RFC1321, which is an international standard of the IETF (S420).

Then, the identification system storage module 210, if the shortened identification system of the local network slice identification system delivered from the identification system registration unit 100 matches the shortened identification system mapped to the registered local network slice identification system, Each local network slice identification system is integrated and stored as a global network slice identification system (S430-S440).

Next, the identification system management module 220 generates a shortened identification system for the integrated global network slice identification system, and stores the generated global network slice shortened identification system by mutually mapping the stored global network slice identification system (S450). ).

Then, the identification system management module 220 delivers the global network slice reduction identification system to each local network slice constituting the global network slice identification system through the identification system registration unit 100, thereby identifying the identification system registration unit 100. It is possible to map and manage each local network slice constituting the global network slice identification system and the global network slice shortened identification system (S460).

On the other hand, the identification system management module 220 identifies the local network slice abbreviation identification system, if the short identification scheme of the local network slice identification scheme does not match the reduced identification system mapped to the registered local network slice identification scheme. By transmitting to the local network slice through the registration unit 100, the identification system registration unit 100 can be managed by mapping the local network slice shortened identification system to the local network slice (S470).

Thereafter, the identification system management module 220 generates a shortened identification system for the updated local network slice identification system, as described above, when the local network slice identification system previously registered by the identification system update unit 300 is updated. Through the identification system registration unit 100 is delivered to the local network slice. In addition, the identification system management module 220 generates a shortened identification system for the updated global network slice identification system, as described above, even when the global network slice identification system previously registered by the identification system update unit 300 is updated. Then through the identification system registration unit 100 is transmitted to each local network slice constituting the updated global network slice identification system (S480-S500).

Hereinafter, an operation method of the identification system updater 300 (identification system updater) will be described with reference to FIG. 8.

First, when the change state of the registered local network slice identification system is detected in the identification system registration unit 100 or when the change or deletion state of each local network slice identification system included in the global network slice identification system is detected, the change is changed. The identification module 310 receives the changed local network slice identification system together with the corresponding local network slice shortened identification system or the global network slice shortened identification system from the identification system registration unit 100 (S510).

Then, the identification system update module 320 extracts the local network slice identification system mapped to the identification system management unit 200 based on the received shortened identification system and stores the extracted local network slice identification system in the changed local network. Update to reflect slice identification. On the other hand, the identification system update module 320, if a specific local network slice identification system included in the global network slice identification system is changed or deleted, to the identification system management unit 200 based on the shortened identification system for the specific local network slice. After extracting and updating the mapped and stored specific local network slice identification system, the updated network state is extracted by mapping the stored global network slice identification system to the identification system management unit 200 based on the global network slice shortened identification system to reflect the update status. (S520-S540).
