Network function virtualization, or Network Function Virtualization (NFV), separates the hardware and software components of the network and virtualizes the functions of the physical networking facilities to provide a number of virtual machines (VMs) Ding is a concept that runs on a computer.

According to this, various network devices such as routers, load balancers, firewalls, intrusion prevention, and virtual private networks can be implemented as software on general servers, thereby avoiding the vendor dependency of the network configuration. Expensive dedicated equipment can be replaced by general-purpose hardware and dedicated software. Furthermore, it has the advantage of being able to quickly cope with traffic change as well as equipment operation cost reduction.

Software-defined networking (SDN) technology, on the other hand, separates the complexity of the control plane from the data plane. According to this, the complicated functions of the control plane are processed by software, and the data plane can perform only simple functions indicated by the control plane, such as transferring, ignoring, and changing network packets. With these changes, software can develop new network functions without complex hardware constraints, while at the same time making various attempts that were not possible with previous network architectures.

The NFV and the SDN are separate technologies, but can complement each other. This is because various network functions implemented by software by NFV can be efficiently controlled using SDN.

It is to be understood that the present invention is not limited to the description of the embodiments described below, and that various modifications may be made without departing from the technical scope of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

In the drawings, the same components are denoted by the same reference numerals. And in the accompanying drawings, some of the elements may be exaggerated, omitted or schematically illustrated. It is intended to clearly illustrate the gist of the present invention by omitting unnecessary explanations not related to the gist of the present invention. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a configuration of a wireless router 100 according to the present invention.

The wireless router (100) according to an embodiment of the present invention may include a communication unit (110) and a control unit (140).

In the example of Fig. 1, the communication unit may include a wireless LAN module for transmitting / receiving signals with the client device via network hardware, and a physical port for connecting the network.

The control unit may support a software switch module 142 and / or a plurality of virtual network functions (VNF) modules 149 as computing hardware.

The virtual network function 149 can perform functions that the conventional hardware-based network equipment such as load balancing, virtual private network, firewall, intrusion prevention function, and the like provide individually in the wireless router. In the example of FIG. 1, the network function of the wireless router is assumed to be implemented by software, but the present invention is not limited thereto. That is, a module for providing a network service may be provided on a hardware basis according to a conventional method.

Meanwhile, the software switch 142 is connected to a virtual network hub (Virtual Network Hub) that connects an external physical network with virtual network devices running on the server through the virtual network interfaces 151, 152, 153, 161, 162, ) Can play a role.

Meanwhile, the wireless router 100 basically divides one line into a plurality of devices to provide a network service. However, in the conventional wireless router, the user can not divide the circuit itself and resell it. In other words, if an individual user purchases a 10G line, even if only 3G is used, the remaining 7G can not be separated and sold again.

The present invention is intended to solve the above problems. According to an embodiment of the present invention, a network bandwidth allocated to a specific line can be divided through a wireless router to provide a service for renting to another user.

To this end, the wireless router 100 according to an embodiment of the present invention further includes a network rental module 148. [

In the example of FIG. 1, the network rental module 148 is shown implemented in the wireless router 100, but the present invention is not limited in this regard. That is, the network rental module may be installed in a separate network rental service server physically separated from the wireless router, and may control the wireless router 140 through the kernel module 170 of the wireless router.

The network rental module 148 according to an embodiment of the present invention generates an SSID for network renting, creates a virtual port for providing network service to the SSID, connects the created virtual port to the software switch, The flow that matches the ports can be defined to set the maximum bandwidth to be borrowed to the SSID.

For example, a user may consider reselling 7G of a 10G line. First, a user may execute a network rental service application according to an embodiment of the present invention in his / her smartphone.

The user can set the bandwidth to be resold to 7G and divide the bandwidth into two states, and set it to 5G for the first tag and 2G for the second tag through the application. Furthermore, the selling price may be set by bandwidth and / or by type.

At this time, the network renting module 148 according to the embodiment of the present invention can receive the information on the user setting and allocate the maximum bandwidth per each constituent.

More specifically, the network rental module 148 generates a per-SSID to provide independent network services for a plurality of subjects, generates a virtual network port for each SSID, and assigns the virtual network port to the SSID at a ratio of 1: 1 can be matched.

Furthermore, the network borrowing module can create one more virtual network port to control the bandwidth used by the user with the value set by the user. This is intended to limit the maximum bandwidth per timetable using the meter table protocol supported by the open flow standard.

More specifically, the network rental module generates a flow rule for matching the first virtual network interface to the second virtual network interface, and generates a meter table for limiting the maximum bandwidth for each flow, thereby limiting the maximum bandwidth per each . The meter table supported by the open flow standard may limit the maximum bandwidth to the flow, and the meter table may be implemented in the wireless router by the network rental module 148 according to conventional techniques.

In the previous example, in which the user divides the bandwidth of 7G into two, and sells 5G for the first, and 2G for the second, the network rental module assigns the first and second It is possible to generate two SSIDs and create two first virtual network ports and match them to the SSIDs in a one-to-one correspondence.

Furthermore, the network rental module creates two second virtual network ports to limit the maximum bandwidth to 7G for the first country and 2G for the second country, and transmits the first virtual network module and the second virtual network module You can create a matching flow table and create a meter table that limits the maximum bandwidth to 7G for the first flow and 2G for the second flow.

On the other hand, the network rental module 148 may purchase a line renting service, generate a web page in advance for setting a detailed item of the purchased service, and forward the web page to the client when a new client connects . The web page includes a billing function, and a description of bandwidth and / or fees may be provided.

Through these web pages, new clients can create network service accounts, purchase line rental services, and set details of resale services. For example, it is possible to register a plurality of devices to be used for the line, register the maximum number of connectable devices, and set a password or the like. That is, the new client can be provided with an independent service for the purchased line.

3 is a flowchart illustrating a method of providing a network rental service according to an embodiment of the present invention.

The wireless router according to the embodiment of the present invention may provide a network service for a specific line like a general wireless router in step 210. [

On the other hand, if the user wants to resell the bandwidth of the corresponding line in step 220, the user can install the network rental service application in the terminal of his / her own smart phone, tablet, PC, and the like and perform detailed setting.

For example, according to an embodiment of the present invention, a user can purchase a line reselling service in an open market, and a user who purchased a service can download an application for providing a network rental service to the terminal from a service server. Further, a network rental service server according to an embodiment of the present invention may install a software module for providing a network rental service to a wireless router supporting network function virtualization.

In step 230, the service server may generate an SSID for each of the participants in the wireless router according to the user setting, and may implement a virtual network interface for providing independent services for each of the groups, and may match the SSID with the SSID.

Furthermore, the service server can create a web page that can purchase and set network bandwidth. This will be forwarded to the new client when the new client connects to the router.

On the other hand, in step 240, the service server can limit the maximum bandwidth of the configurator in order to sell the bandwidth according to the user setup. More specifically, the service server can define the packet flow and set the maximum bandwidth for the flow using a meter table supported by the open flow standard.

More specifically, the service server can generate one set of the virtual network interface as many as the predetermined number. Furthermore, a flow rule for matching the first virtual network interface to the second virtual network interface may be generated to define a flow.

Furthermore, the service server can create a metric table that limits the maximum bandwidth per flow, thereby limiting the maximum bandwidth per each type. The metric table supported by the open flow standard may limit the maximum bandwidth to a flow defined by a port value or the like, and the metric table may be implemented by the network rental module 148 according to a conventional technique.

When the new client connects in step 250, the service server can forward the previously generated web page for service provision to the client. The client can purchase the resale network line through the web page and set the detailed network function.

More specifically, if the client does not have an account for the service, the client can create an account via the web page at step 260.

In step 270, the client can select a resale line and settle it, and can register a plurality of devices to use the line, register the maximum number of connectable devices, and set a password or the like. The wireless router can then provide the client with an independent network service for the resale line. (Step 280)
