Description

[0001] The present invention relates to a method and system for managing VNF licenses in an NFV service environment,

The present invention relates to a network function virtualization (NFV) technology, and more particularly, to a VNF license management method and system for efficiently managing a VNF (Virtualization Network Function) license in an NFV service environment.

As Internet use explosively increases, structural problems inherent in existing Internet such as mobility, security, and quality guarantee limit are revealed. In order to solve this problem, it is required to construct a future-oriented network and service infrastructure that enables various future application services to be used quickly and safely. In response, Network Function Virtualization (NFV) technology is being developed. The following Patent Document discloses a method for processing a large amount of data and constructing a high performance NFV system.

Network Functional Virtualization (NFV) is a software virtualization control and management of network functions. NFV is a technology that virtualizes telecommunication service providers in a way that enables them to control and manage software by separating various functions within the network equipment. NFV is implemented in a variety of ways, but in a common way, the functions within a network device are separated into a firewall, a large server, a mass storage device, and a large capacity switch located in a data center, and access is made by a standard method. It also creates a network structure that automatically installs, operates, and moves software functions developed on these devices.

The biggest advantage of the NFV-based system is that it can virtualize a general-purpose hardware-based server resource in the form of a virtual machine, and build and expand a virtual machine on-demand as the service usage increases It is a point. In this way, telecom operators can reduce capital expenditure (CAPEX) and OPEX (operating expense) costs by building equipment at minimum cost. Furthermore, it is possible to establish an environment that can respond quickly to various services through a flexible infrastructure.

Virtualization Network Function (VNF) in the NFV Architecture refers to the network function developed by software to support various applications. For example, a media resource function (MRF), a call session control function (CSCF), a home subscriber server (HSS), a packet gate wire (P-GW), a unified threat management (UTM), a web application firewall Intrusion Prevention System). These VNFs gather to provide NFV services.

Each of these VNFs is provided by different vendors. In order to mount the corresponding VNF on the client server, the license must be purchased from the vendor and the VNF must be mounted on the server in the form of a virtual machine.

In order to install a large number of VNFs on a server of a customer, conventionally, each vendor installer visits the site, installs a VNF on a customer server, and registers a license. However, this method not only requires a lot of labor, but also takes a long time, which causes a delay in the overall service of the client server. In addition, since the customer must directly manage the VNF-specific licenses registered in his / her server, it is difficult to manage the VNF installed in the client server.

At this time, the client terminal 110 records the required capacity of the virtual CPU, the required capacity of the virtual memory, the service usage period, the IP address of the customer server, and the necessary VNF (Virtualization Network Function) information necessary for executing the NFV service And transmits the service request information to the VNF license management system 200.

The customer server 120 is a server that provides NFV services to subscribers based on cloud computing, and may be installed separately in a customer company or may be mounted in a cloud server system commonly used as a virtual server.

The customer server 120 receives one or more VNF images from the VNF license management system 200 and installs one or more virtual machines that implement each VNF by installing one or more VNF images. In addition, the customer server 120 registers the license for each VNF by controlling the VNF license management system 200, sets an operating environment for each VNF, and transmits the NFV service by the VNF to the client terminal 110 to provide.

The vendor system 300 is a system built by a manufacturer or a vendor that develops or sells one or more VNFs and provides its own VNF license to the VNF license management system 200. When the vendor system 300 is requested to verify the validity of the VNF license from the customer server 120, the vendor system 300 verifies whether the license is valid and provides the verification result to the customer server 120. At this time, if it is verified that the license is valid, the vendor system 300 transmits information allowing the use of the VNF to the customer server 120, so that the customer server 120 normally uses the VNF.

The VNF license management system 200 acquires a VNF license from each vendor system 300, and manages and distributes the acquired VNF license to the customer. Specifically, when the VNF license management system 200 receives an NFV-based service request from the client terminal 110, the VNF license management system 200 analyzes the requested service and identifies one or more NFVs required for the analyzed service. In addition, the VNF license management system 200 can identify the NFV images required for each NFV to be loaded, send the NFV images to the customer server 120, and provide one or more virtual machines .

In addition, the VNF license management system 200 registers the VNF license with the customer server 120 in which the virtual machine is installed. In one embodiment, the VNF license management system 200 may pre-store NFV-specific licenses and register such pre-stored VNF licenses with the customer server 120. In another embodiment, the VNF license management system 200 requests the corresponding VNF license to the vendor system 300 at the time the service is requested from the client terminal 110, obtains the VNF license in real time, To the customer server (120).

In addition, the VNF license management system 200 sets the operating environment (e.g., IP address, etc.) of the VNF virtual machine so that the virtual machine can execute the VNF normally.

2 is a diagram illustrating a configuration of a VNF license management system according to an embodiment of the present invention.

As shown in FIG. The VNF license management system 200 includes a service verification unit 210, a license management unit 220, an image providing unit 230, an environment setting unit 240, and a database 250, Or through a combination of hardware and software.

The database 250 stores various data for providing NFV-based services and includes a license pool 251 and a management table 252 as storage devices. The database 250 may store NFV-specific images. That is, the database 250 may store NFV-specific images provided by each vendor system 300. [ The NFV image is software for mounting the corresponding NFV on a server in the form of a virtual machine.

The license pool 251 stores NFV-specific licenses. The license pool 251 stores the license information distributed to the customer (that is, in use), information on the unused license, and the usable period of the license together.

The management table 252 is a table for storing usage records for licenses in use, and includes a license distribution date, a license expiration date, license information, customer information, vendor information, license identification information, and the like.

The service confirmation unit 210 performs a function of confirming a service requested from the client terminal 110. [ When receiving the service request message from the client terminal 110, the service verifying unit 210 extracts the virtual CPU capacity, the virtual memory capacity, the service utilization period, the IP address of the customer server 120, and the required VNF Check the information. The service confirmation unit 210 may also receive the service change information from the client terminal 110. [

The license management unit 220 identifies the NFV required for the NFV service requested by the customer and selects the license of the identified NFV in the license pool 251. [ Specifically, the license management unit 220 identifies the VNF required for the NFV service of the client terminal 110 based on the VNF information confirmed by the service verification unit 210, identifies the unused VNF among the plurality of licenses corresponding to the identified VNF, It determines whether a license exists in the license pool 251 and selects any one of the unused VNF licenses as a license to be provided to the client server 120 if it exists. In addition, when a license of a specific VNF is selected, the license management unit 220 records usage information (for example, in-use) in the license pool 251 to update the license pool 251. In addition, the license management unit 220 maps the license issuance date, license expiration date, customer information, vendor information, and the like to the management table 252 and stores them.

The image providing unit 230 transmits one or more VNF images to the client server 120, and mounts a virtual machine for realizing the VNF in the client server 120. That is, the image providing unit 230 sends one or more VNF images, which correspond to the requested virtual CPU capacity and virtual memory capacity, and in which the requested VNF can be mounted on the customer server 120 in the form of a virtual machine, (120). The image providing unit 230 may extract the VNF image from the database 250 and transmit the extracted VNF image to the client server 120.

The environment setting unit 240 sets the operating environment of the VNF virtual machine when the VNF virtual machine is installed in the customer server 120. Specifically, the environment setting unit 240 transmits operating environment setting information including VNF virtual IP address, network setting information such as a subnet mask, VNF license, and the like to the client server 120 to obtain a license of the VNF virtual machine And sets the operating environment of the VNF virtual machine.

On the other hand, the environment setting unit 240 can change the operating environment of the VNF virtual machine installed in the customer server 120 based on the service change information, when receiving the service change information from the service check unit 210. For example, the environment setting unit 240 can change the virtual CPU capacity, the virtual memory capacity, the virtual IP address, etc. of the virtual machine mounted on the customer server 120 based on the service change information.

3 is a flowchart illustrating a method of managing a VNF license in a VNF license management system according to an exemplary embodiment of the present invention.

3, the client terminal 110 transmits an NFV service request message including the number of virtual CPUs, the number of virtual memories, the service utilization period, the IP address of the customer server 120, one or more VNF information, etc. to the VNF license management To the system 200 (S301).

Then, the service checking unit 210 checks the requested NFV service based on the respective information included in the NFV service request message (S303). That is, the service checking unit 210 checks the number of virtual CPUs, the number of virtual memories, the service usage period, the IP address of the customer server 120, and the required VNF information included in the service request message to check the requested NFV service do.

Then, based on the VNF information included in the NFV service request message, the license management unit 220 identifies a VNF required for the service of the client terminal 110 among the plurality of VNFs. The license management unit 220 checks whether an unused license among a plurality of licenses corresponding to the identified VNF is present in the license pool 251. If the unused license exists in the license pool 251, (S305). Then, the license manager 220 records usage information (for example, in-use) in the license pool 251 and updates the license pool 251 (S307). Also, the license management unit 220 maps the license issuance date, the license expiration date, and the customer information to the management table 252 and stores them.

Meanwhile, if the license corresponding to the identified VNF is being used, the license management unit 220 can notify the client terminal 110 that the service can not be provided. As another embodiment, if the license management unit 220 confirms that the license corresponding to the identified VNF is being used and is being used in the license pool 251, the vendor system 300 that manufactures or sells the VNF may transmit a new VNF license May be requested and obtained.

When the license selection is completed, the image providing unit 230 transmits the VNF image corresponding to the requested service to the client server 120 (S309). That is, the image providing unit 230 transmits the VNF image, which is the base on which the VNF including the virtual CPU capacity and the virtual memory capacity are mounted, to the customer server 120. At this time, the image providing unit 230 may extract the VNF image corresponding to the identified VNF image from among the plurality of VNF images stored in the database 250, and transmit the extracted VNF image to the client server 120. As another example, the image providing unit 230 may reconfigure the VNF image extracted from the database 250 to match the service requirement (i.e., the virtual CPU capacity and the virtual memory capacity) (120).

The customer server 120 receiving the VNF image drives the virtual machine based on the VNF image and mounts the VNF in the form of a virtual machine (S311).

When the VNF implemented as a virtual machine is loaded in the client server 120, the configuration unit 240 connects to the client server 120 and proceeds to set the operating environment of the VNF. That is, the environment setting unit 240 transmits the operating environment setting information including the network setting information such as the virtual IP address of the VNF, the subnet mask, and the selected VNF to the client server 120 to the client server 120 (S313).

Next, the customer server 120 registers the license of the VNF based on the operating environment setting information (S315), and changes the network or the like to set the operating environment of the VNF (S317). When the setting of the operating environment is completed, the customer server 120 requests the vendor system 300 that manufactured or sold the VNF to verify the validity of the VNF (S319). At this time, the customer server 120 transmits the registered VNF license to the vendor system 300, thereby requesting the validity verification of the VNF.

Next, the vendor system 300 analyzes the license of the VNF received from the customer server 120, verifies whether the VNF license is valid, and transmits the verified result to the customer server 120 (S321 ).

If the verification result received from the vendor system 300 is confirmed to be a failure, the customer server 120 outputs to the monitor that the license of the VNF is not normal. In addition, the VNF license management system 200 notifies the VNF license management system 200 of the new license Request deployment.

If the verification result received from the vendor system 300 is confirmed to be successful, the client server 120 sets the VNF to an available state and provides a service by the VNF to the client terminal 110 (S323).

As described above, according to the embodiment of the present invention, the VNF license management system 200 integrates and manages the VNF license, and when a VNF service request is received from a customer, the VNF license management system 200 transmits a VNF virtual machine And registering the VNF license in the customer server 120, the NFV service can be provided to the customer more conveniently and quickly.

Meanwhile, distributing the VNF license requested by the customer to the customer while purchasing the VNF license from the vendor in advance and storing it in the license pool 251 may cause unnecessary expenses to the NVF service provider. That is, if the VNF license is not distributed to the customer while the VNF license is pre-purchased from the VNF provider (i.e., vendor) and stored in the license pool 251, the NFV service provider pays for the license fee do.

In another embodiment below, VNF license management methods and systems that do not increase the license purchase cost of an NFV service provider are described.

The database 470 stores various data for providing NFV-based services and includes a management table 471 as a storage device. The database 470 may store NFV-specific images. The management table 471 is a table for storing usage records for licenses in use, and includes a license distribution date, a license expiration date, license information, customer information, vendor information, and the like, which are mapped on a VNF basis.

Upon receiving a request for an NFV service from the client terminal 110, the license acquisition unit 450 acquires a VNF license required for the NFV service from the vendor system 300. That is, when the NFV service is requested from the client terminal 110 and the VNF information is confirmed by the service verification unit 210, the license acquisition unit 450 identifies the vendor system 300 that manufactures or sells the VNF, And requests the vendor system 300 to license the VNF. At this time, the license acquisition unit 450 confirms the service use period requested by the client terminal 110, requests the vendor system 300 for a usable VNF license in the service use period, and transmits the VNF license from the vendor system 300 . Also, the license acquisition unit 450 maps the license issuance date, license expiration date, customer information, vendor information, and the like to the management table 471 and stores it.

The expense settlement unit 460 performs post-processing of the license purchase cost. That is, based on the management table 471 of the database 470, the cost settlement unit 460 postpones each license purchase cost to the vendor. The cost settlement unit 460 confirms the usage period for each VNF license in the management table 471 and pays the VNF license fee to each vendor.

Then, the service checking unit 210 checks the requested NFV service based on the respective information included in the NFV service request message (S503). That is, the service checking unit 210 confirms the requested service by checking the virtual CPU capacity, the virtual memory capacity, the service utilization period, the IP address of the customer server 120, and the necessary VNF information included in the NFV service request message .

Then, the license obtaining unit 450 identifies one or more VNFs necessary for the service of the client terminal 110 based on the VNF information included in the NFV service request message. Then, the license management unit 220 confirms the vendor system 300 that manufactures or sells the identified VNF, and requests the vendor system 300 to issue the license of the identified VNF (S505). At this time, the license acquisition unit 450 confirms the service use period requested by the client terminal 110, and requests the vendor system 300 for a usable VNF license in the service use period.

Next, the vendor system 300 transmits the license of the VNF used in the service utilization period to the VNF license management system 200 (S507), and the license acquisition unit 450 receives the VNF license, Obtain the VNF license required for the NFV service. Next, the license obtaining unit 450 maps the license issuance date, the license expiration date, the customer information, the vendor information, and the like to the management table 471.

Then, when the license acquisition is completed, the image providing unit 230 transmits the VNF image corresponding to the requested service to the customer server 120 (S509). That is, the image providing unit 230 transmits the VNF image for mounting the VNF including the virtual CPU capacity and the virtual memory capacity to the virtual machine to the customer server 120.

The customer server 120 receiving the VNF image drives the virtual machine based on the VNF image, and mounts the VNF in the form of a virtual machine (S511).

When the VNF implemented in the virtual machine is loaded in the customer server 120, the environment setting unit 240 transmits the network setting information such as the virtual IP address and the subnet mask of the VNF to the client server 120, And transmits the operating environment setting information including the obtained VNF license to the customer server 120 (S513).

Next, the customer server 120 registers the license of the VNF based on the operating environment setting information (S515), and changes the network or the like to set the operating environment of the VNF (S517). When setting of the operating environment is completed, the customer server 120 requests the vendor system 300 that manufactured or sold the VNF to verify the validity of the VNF (S519). At this time, the customer server 120 transmits the registered VNF license to the vendor system 300, thereby requesting the validity verification of the VNF.

Next, the vendor system 300 analyzes the license of the VNF received from the customer server 120, verifies whether the VNF license is valid, and transmits the verified result to the customer server 120 (S521 ).

If the verification result received from the vendor system 300 is confirmed to be successful, the customer server 120 sets the VNF to an available state and provides a service by the VNF to the client terminal 110 (S523).

As described above, according to another embodiment of the present invention, the VNF license management system 200 requests and issues a license to the vendor system 300 at a point in time when a VNF license is required, This can reduce the cost of licensing management that occurs.
