Abstract

A method of providing a quality of service (QoS) service of an internet service provider (ISP) system comprises a step where an internet protocol (IP) address allocation system included in the ISP system verifies information on a type of a terminal and information on a type of the service which are transmitted through a network equipment included in the ISP system by network bootstrap operation of the terminal; and a step where the IP address allocation system provisions QoS service policy information about the terminal via the network equipment based on the verified information on the type of the terminal or information on the type of the service.

Description

TECHNICAL FIELD [0001] The present invention relates to a method of providing a QoS service of an ISP system, and an IP address allocation server of an ISP system for providing a QoS service,

The present invention relates to a machine-to-machine communication (M2M) technology, and more particularly, to an Internet protocol (IP) -CCTV (Closed Circuit Television) or home monitoring (QoS) defined by an ISP system (ISP network) for an end-to-end interval between a terminal (or gateway) and a service or application server (e.g., a smart home service server) A method of providing a QoS service by an ISP system for providing a service policy, and an IP address allocation server of an ISP system for providing a QoS service.

The M2M market or M2M solution range is gradually expanding from the enterprise center to the consumer market. Telematics, telemetry, or location tracking have been the mainstream, but nowadays, due to the expansion of user terminals targeting consumers, it is becoming increasingly important that u-health, e-book, or smart home The consumer market is rapidly expanding.

As the M2M market is increasingly becoming a sensitive consumer for quality of service (QoS), controversy over quality of service (QoS) becomes an issue. There is currently a discussion on the QoS provision method for the M2M market, which is currently being discussed by standards bodies such as ETSI (European Telecommunications Standards Institute), but there is no clear direction. The M2M terminal is subject to network quality competition with a general purpose terminal (for example, a PC (personal computer)) on the basis of a best effort service (the best service such as an Internet service), and in a network congestion The terminal can not provide the service. In particular, terminals related to security controls such as security (e.g., home security) or monitoring (e.g., home monitoring) are associated with an individual's life, property, or safety, .

With regard to the QoS-related progress of the M2M standards bodies described above, the requirements of the QoS field are still not established in the M2M standards bodies. The reason for this is that the standard group (ETSI, etc.) activities are mainly working on vendor oriented terminal / gateway (GW) and platform standards, and the activity of Internet service provider (ISP) The requirements of the QoS field in the ISP's network domain may not be easy to obtain. Therefore, in the standards body, the requirements of QoS automatic provisioning and M2M device / GW provided by the ISP should be established in order to guarantee QoS in the network congestion situation.

1 is a diagram showing an example of a QoS service configuration according to the prior art.

Referring to FIG. 1, a home network service providing method can be described as follows. The service data of the application service server (application / svc server), which is a web server, is transmitted to the M2M terminal or the M2M gateway terminal through the network equipment included in the ISP, (Best Effort), which is the same level of quality of service (QoS) as a general-purpose terminal. That is, all the terminals in the general-purpose terminal and the M2M device or gateway provided by the ISP network are provided with the same service quality (service data). Therefore, the service system shown in FIG. 1 has a structure in which M2M data is lost in a network congestion with general traffic due to Best Effort competition. Therefore, in the service system of FIG. 1, data such as a home security service In the event of a loss, it may directly lead to personal property or life, resulting in serious consequences.

In another example of the related art, a method of provisioning a QoS policy between a terminal and a platform (service server) by a home service provider or a solution sales company irrespective of an ISP system (ISP network) has been proposed. Although the QoS scheme can be guaranteed in the home network domain, the service scheme can not provide a QoS service from the end-to-end viewpoint between the terminal and the service server.

More specifically, a QoS service is provided between a specific service terminal and a platform (service server) regardless of the QoS policy of the ISP system. In the service providing method as described above, a service to be guaranteed by the QoS system from the ISP system can be provided with the same quality of service (QoS) as a general purpose terminal.

The prior art has the following problems.

First, in establishing a QoS policy of a specific service provider or solution vendor that is not related to an ISP (Internet Service Provider) system, a specific service provider / solution sales company establishes a QoS policy that distinguishes a terminal type (terminal type) QoS in a domain (for example, a home network domain) may be guaranteed, but it may not be possible to provide an end-to-end QoS service. In addition, since the QoS policy determination is performed in the bootstrap process of the terminal for providing a specific service, the corresponding process can also be a structure in which QoS loss in the local domain can not be guaranteed due to traffic loss in the network congestion process .

Second, in the ISP system, it may not be possible to establish a QoS policy for a specific service provider or solution vendor. Because the terminal type or service provided by a specific service provider / solution vendor is indistinguishable, the QoS policy establishment by the ISP system may not be possible in the prior art.

Third, the prior art may have a structure in which it is impossible to collaborate with a service provider and ISP in order to provide end-to-end QoS. Providing an end-to-end QoS service in a situation where the service provider and the ISP (or NSP: Network Service Provider) are physically or logically separated may not be possible in the prior art.

The technical problem to be solved by the present invention is not a QoS policy arbitrarily set by a user or a network service provider but a case where a terminal such as an M2M terminal accesses an ISP system through a network bootstrap process A method of providing a QoS service of an ISP system in which an ISP system determines a QoS policy of the terminal and provision thereof, and an IP address allocation server of an ISP system for providing a QoS service.

According to an aspect of the present invention, there is provided a method of providing a Quality of Service (QoS) service of an Internet Service Provider (ISP) system, Confirming the type information or service type information of the terminal transmitted through the network equipment included in the ISP system by a network bootstrap operation of the ISP system; And provisioning QoS service policy information to the terminal through the network equipment based on the type information or the service type information of the terminal determined by the IP address assignment system.

The method for providing a QoS service of the ISP system is a method for allowing the network equipment of the ISP system to confirm the trust of the provisioned QoS service policy information when the terminal requests an Internet service through the network equipment And checking QoS service policy information using a QoS mapping table including a prefix corresponding to type information or service type information of the UE.

The terminal may include an IP address assignment request information item having vendor specific information of a DHCP option field including type information or service type information of the terminal in the IP address assignment system, .

The ISP address assignment system may further include a QoS policy information management unit for managing the QoS policy information of the M2M terminal in a case where the type information of the terminal is a machine to machine communication (M2M) terminal and the service type information of the terminal is a security service, It is possible to determine the low-QoS silver policy information.

The ISP address assignment system may be configured such that when the type information of the terminal is the M2M gateway terminal, the QoS service policy information of the home monitoring terminal connected to the M2M gateway terminal is set to a bronze policy And determine the QoS service policy information of the appliance connected to the M2M gateway terminal as the best effort policy information with lower QoS than the bronze policy information.

According to an aspect of the present invention, there is provided an IP address assignment server of an ISP system for providing a QoS service, comprising: a storage unit for storing QoS service policy information corresponding to type information or service type information of a terminal; A communication unit for receiving IP address allocation request information including terminal type information or service type information from a terminal through a network equipment included in the ISP system; And a control unit for referring to the QoS service policy information for type information or service type information stored in the storage unit corresponding to the type information or service type information of the terminal included in the IP address allocation request information of the terminal received by the communication unit, Determining QoS service policy information of the terminal, assigning an IP address corresponding to the IP address allocation request information of the terminal received in the communication unit, and transmitting the QoS service policy information and the assigned IP address of the determined terminal to the communication unit And a controller for controlling the terminal to be provisioned to the terminal through a network device.

The IP address assignment request information may include vendor designation information of a DHCP option field including type information or service type information of the terminal.

If the type information of the terminal is the M2M terminal and the service type information of the terminal is the security service, the control unit may determine the QoS service policy information of the M2M terminal as the lower-level silver policy information than the gold policy information.

Wherein the control unit determines QoS service policy information of a home monitoring terminal connected to the M2M gateway terminal as bronze policy information having lower QoS than silver policy information when the type information of the terminal is an M2M gateway terminal, The QoS service policy information of the home appliances connected to the home network can be determined as the best effort policy information with lower QoS than the bronze policy information.

The method for providing a QoS service of an ISP system according to the present invention and the IP address assignment server of an ISP system for providing a QoS service are methods for configuring an ISP network for providing an M2M terminal and a gateway QoS service, It is possible to guarantee end-to-end QoS provided according to the QoS policy. Therefore, the present invention can establish an infrastructure for providing a QoS policy to the M2M market or an infrastructure for providing a high quality at a reasonable cost without incurring a separate investment cost for various facilities. That is, the present invention can enable various business models related to service quality and new revenue sources through provision of a network (ISP) driven QoS policy rather than a market (specific service provider) driven. Also, the present invention can ensure integrity or reliability of service provision through QoS mapping table management.

The present invention can improve the quality of the M2M service according to the provision of the selective QoS policy for the terminals in the M2M Device / Gateway domain. More specifically, the present invention can improve quality of service through providing selective QoS according to the type of terminal or service type of terminal in M2M object communication. The present invention can improve differentiated service provision and reliability by providing QoS mapped to a terminal type or a terminal service type. That is, high quality services can be provided and reliability of services can be improved through QoS guarantee of mission critical services such as security or security.

The present invention is an efficient QoS providing method for ensuring quality of service, and can solve the constraints and implementation constraints of the conventional local service quality assurance method in the local domain.

The present invention can establish QoS requirements in a standard entity such as ETSI and establish QoS requirements in an end-to-end view rather than a QoS provision method in a local domain.

2 is a view for explaining a QoS service providing system 100 to which a QoS service providing method of an ISP system according to an embodiment of the present invention is applied.

2, a QoS service providing system 100 is a smart home system, for example, including a terminal / gateway domain 110 and a network domain 145, . The QoS service providing system 100 may be an ISP network configuration system for providing a QoS service for the M2M terminal and the gateway.

A terminal and a gateway domain 110 are terminal and gateway systems installed in a home, for example, as an M2M terminal (M2M device) which can be installed on a front door of a home, A sensor information collecting terminal (M2M device) 125, which is an M2M terminal, and an M2M gateway terminal 130. The IP- The sensor information collecting terminal (M2M device) 125 can collect sensor information from various sensor devices 120 such as an image camera (for example, an infrared image camera) that can be installed in a window of a home . The M2M gateway terminal 130 is provided with a home monitoring terminal 135 such as a web camera that can be installed in a PC (personal computer) such as a room in a home via a wireless communication network or a wired communication network, household appliance such as refrigerator 140 which is general purpose M2M terminal is connected.

The network domain 145 is a network system that includes an IP address assignment system 150 and network equipment 155 included in the ISP system and an application or service system 160 (application / svc system) . The application / svc system 160 includes a CCTV service server (CCTV), a security service server (SEC), a home monitoring service server (MON), and a home appliance service server (HOME).

The CCTV service server (CCTV) may be a server that manages security information (security video information) collected by the IP-CCTV 115 or operation control such as on or off of the IP-CCTV 115. The security service server SEC may be a server for managing security sensor information collected by the sensor information collection terminal 125 or operation control such as on or off of the sensor information collection terminal 125. The home monitoring service server MON may be a server that manages security information (security image information) collected by the home monitoring terminal 135 or operation control such as on or off of the home monitoring terminal 135. The home appliance service server (HOME) may be a server that manages operation control such as on or off of the home appliance 140.

The IP-CCTV 115, the sensor information collecting terminal (M2M device) 125 and the M2M gateway terminal 130 are connected to the network device 155 and the IP address assigning system 155 included in the network domain 145, The IP address assignment system 150 may access the IP-CCTV 115, the sensor information collection terminal (M2M device) 125 via the network equipment 155, , And the M2M gateway terminal 130, respectively, in order to provide QoS service policy information.

After the QoS provisioning is performed, each of the IP-CCTV 115, the M2M device 125 and the M2M gateway terminal 130 transmits an application / svc System 160 to transmit or receive information related to the service. QoS priority, which is QoS service policy information, in a service packet when the IP-CCTV 115, the sensor information collecting terminal (M2M device) 125, and the M2M gateway terminal 130 use the corresponding service, (Or QoS level) is marked (or set). The network equipment 155 may remark (or modify) the QoS for the unregistered terminal accessing the network equipment 155. That is, the network equipment 155 can modify the QoS priority of the corresponding terminal when the QoS priority, which is the QoS service policy information, is not the QoS priority registered in the corresponding terminal, in the delivered service packet.

2, an embodiment of a QoS service providing method of an ISP system according to the present invention can be described as follows.

An embodiment of the QoS service providing method of the ISP system includes an M2M gateway 125 connected to the IP-CCTV 115, a sensor information collecting terminal (M2M device) 125 and a home monitoring terminal 135 and a home appliance 140 A step of identifying the type of the corresponding terminal or the service type of the terminal in the IP address allocation system 150 of the ISP system through a network bootstrap process of the terminal 130, Determining QoS policies (QoS service policy information) mapped to a service type of the service system by an IP address assignment system 150 of an ISP system, and transmitting the mapped QoS (Or applying) the QoS policy information to the mobile station, and for remarking the QoS of the unauthorized terminal to secure the reliability of the mapped QoS policy, And mapping the QoS policy of the corresponding terminal in the network equipment 155 of the terminal. Through the above process, the M2M gateway terminal 130 connected to the IP-CCTV 115, the sensor information collecting terminal (M2M device) 125, the home monitoring terminal 135 and the household appliances 140 The QoS policy provided by the ISP system provides QoS (End-to-End) between the device / gateway domain 110 and the application / svc system 160, You can use guaranteed services.

(E.g., IP-CCTV 115) or M2M gateway terminal 130 for QoS policy determination in the ISP system's IP address assignment system 150 or the type of service of the terminal , The present invention uses Network Bootstrap (dynamic host configuration protocol (DHCP), etc.) which is an essential element for providing Internet service in ISP. Since Network Bootstrap is a necessary process for providing Internet service, it can be mapped with high QoS priority (for example, gold rating). An option field that can distinguish the type of the terminal or the service type of the terminal from DHCP, which is a standard protocol for allocating the IP address, may be used. That is, the type of the terminal or the service type of the terminal can be distinguished through the DHCP option 60 (vendor class identifier) or the option 77 (user class identifier) field.

The IP address assignment system 150 of the ISP system determines the QoS policy through the type of the specific terminal or the service classification included in the value of option 60 or 77 field of the DHCP, which is an IP address assignment protocol. The IP address assignment system 150 of the ISP system can determine the QoS policy using the vendor specific information (vendor specific information set in the DHCP option) of the DHCP option used in the network bootstrap process. If the field value is not mapped in the IP address assignment system 150 of the ISP system, automatic provisioning of the QoS policy for the terminal is not performed.

Meanwhile, the network equipment 155 included in the Access Network and the Core Network of the Network Domain 145 manages a QoS mapping table for providing a QoS policy in order to ensure integrity and reliability of the QoS policy. That is, the arbitrarily set QoS policy is not trusted.

In the QoS remarking policy performed by the network device 155, the QoS priority generated in the UE not registered in the QoS mapping table is not trusted, and the QoS priority is remarking with the best effort )do.

As described above, the QoS service providing method of the ISP system according to the present invention provides the QoS policy (QoS service policy information) for the M2M terminal in the Device / Gateway Domain 110. More specifically, the present invention provides QoS priority to terminals (for example, IP-CCTV 115 and sensor information collecting terminal (M2M device) 125), which are related to personal property or life, The Bronze (Bronze) class of the QoS middle priority is provided to the simple home monitoring terminal 135 with a high priority (Gold class or Silver class) ), And can provide a best effort service, which is a QoS lower priority, for the general purpose M2M terminal (for example, the refrigerator 140, the audio, or the PC).

The present invention also provides QoS policy determination and automatic provisioning operations for an M2M terminal using a network bootstrap process in an IP address allocation system 150 of an ISP system for providing E2E (end-to-end) QoS, . Generally, since the network bootstrap process is directly related to the use of the Internet service, the IP address allocation system 150 of the ISP system sets the QoS priority to a high value (generally, a Gold Priority is set). Therefore, the network bootstrap process, which has no possibility of data loss in the initial stage of service, can be utilized in QoS policy determination and provisioning process. The present invention also provides a method for identifying the type of M2M terminal (e.g., IP-CCTV 115) or M2M gate terminal 130 or the service type of the terminal in the Network Bootstrap process, To perform QoS policy determination and automatic provisioning. The M2M terminal or the M2M gateway terminal may apply the QoS policy provisioned in the ISP system's IP address assignment system 150 to its own terminal.

The present invention can also provide the integrity and reliability of the QoS policy determined by the IP address assignment system 150 of the ISP system. That is, the present invention can confirm the integrity and reliability of the QoS policy applied to the M2M terminal (for example, the IP-CCTV 115) or the M2M gateway terminal 130 via the network equipment 155 of the ISP system. There is a possibility of misuse or abuse of QoS when the QoS policy is arbitrarily set by the user side. Therefore, in order to secure the integrity or reliability of the determined QoS in the network equipment 155 of the ISP system, a QoS mapping table of the terminal, Can be managed.

In addition, the present invention can constitute an infrastructure for providing end-to-end QoS. That is, the present invention performs QoS prioritization and QoS priority automatic provisioning of the M2M terminal or the M2M gateway terminal using the Network Bootstrap process in the IP address allocation system 150 of the ISP system, And provides the integrity and reliability of the QoS policy through the network equipment 155 of the ISP system in the network domain 145 and provides the integrity of the QoS policy to the terminal Network Network Domain 145, To-end QoS service between ISP system ↔ Application Domain (160).

3 is a view for explaining a QoS service providing method of an ISP system according to an embodiment of the present invention.

3 and 2, an ISP platform capable of supporting an IP address allocation system 150 of the ISP system, which is an ISP network, includes a broadband home router (BHR), which is a gateway of a home network, (Such as a video providing terminal) connected to the ISP platform by a network bootstrap operation via the network equipment of the ISP network (155 in FIG. 2) and the IP-CCTV 115 ) Or a type or service type of a PC (e.g., a personal computer (PC) having the lowest QoS priority), determines a QoS policy for the terminal, and transmits the determined QoS Provisioning the policy. A home service provider corresponding to the application or service system of FIG. 2 (160 of FIG. 2) can be connected (connected) to the ISP platform via the network. When the video providing terminal starts the corresponding Internet service after applying the provisioned QoS policy, the network equipment 155 confirms the integrity and reliability of the video traffic. Since the video data has high QoS priority (reliability), video traffic is not lost in a network congestion situation. When the PC sets the QoS (for example, a silver grade) arbitrarily without applying the provisioned QoS policy and starts the corresponding Internet service, the network equipment 155 determines the integrity of the PC data Confirm the reliability. The PC data may be set (registered) to the best effort with the lowest QoS priority in the network equipment 155 or the QoS policy of the PC may not be set in the QoS policy of the network equipment 155, 155 may corrupt PC traffic in a network congestion situation by remarketing the QoS policy of PC data to untrusted best effort. Accordingly, the present invention provides an end-to-end QoS service from a home terminal (for example, a video providing terminal or a PC), which is an M2M terminal disposed in a home, to a home service system serving as a service provider using the ISP platform and the network equipment Can be guaranteed.

4 is a view for explaining an example of a QoS providing method compared with the present invention shown in FIG.

Referring to FIG. 4, there is shown an example of providing a QoS service provided between a home service system (home service provider) and a terminal independent of an ISP system (ISP network). In the case of the system shown in FIG. 4, a QoS policy between a terminal and a home service provider is provisioned by a home service provider (a QoS manager of a home service provider) independent of an ISP system. Therefore, since the QoS policy operates independently of the ISP system, QoS in a device / gateway domain including a video providing terminal and a PC can be guaranteed. However, the QoS providing system shown in FIG. 4 is an ISP system And the QoS can not be guaranteed by the QoS remarking policy of FIG. In other words, the ISP network (the network equipment of the ISP network) can remark out (modify) the unreliable QoS policy value. As a result, loss of video or PC traffic can occur in a network congestion situation in the ISP network.

An operation example of the QoS service providing method of the ISP system shown in FIG. 2 or FIG. 3 is described as follows.

2 or 3, the IP address allocation system 150 of the ISP system determines a QoS policy mapped to the terminal type of the M2M terminal or the M2M gateway terminal or the service type of the terminal, And provisioning is automatically performed to the terminal or the M2M gateway terminal. The QoS policy decision mapped to the type or service type of the M2M terminal can be made through the M2M terminal type or the service type prefix (or identifier) of the M2M terminal within the ISP system.

For example, if the prefix is M2M_SEC_xxxx, the terminal type is M2M and the service is an SEC (security) indication, so that the QoS policy can be determined as a silver policy. If the prefix is M2M_HOME_MON_xxxx (or M2M_HOME_SEC), the terminal type is M2M and indicates that the service is home monitoring, so that the QoS policy can be determined as a Bronze policy. If the prefix is M2M_GW_TOTAL, the terminal type is M2M and indicates that it corresponds to the gateway (130 in FIG. 2), so that the QoS policy can be determined as a multi-QoS policy. That is, if the prefix is M2M_GW_TOTAL and M2M_HOME_SEC is the QoS policy is determined as the Bronze policy and the prefix is M2M_GW_TOTAL, M2M_HOME_REFRI, the QoS policy can be determined as the Best Effort service. For other terminals, it can be determined as Best Effort which is a low QoS policy. In the case of QoS policy automatic provisioning, the analyzed information can be provisioned through a network bootstrap process. In the case of automatic provisioning of the QoS policy, the QoS policy value mapped to the type or service type of the M2M terminal is included in the dynamic host configuration protocol (DHCP) option 43 (vendor specific information) The controller 150 may perform provisioning to the M2M terminal or the M2M gate terminal.

The integrity and reliability management operation of the QoS policy by the network equipment 155 of the ISP system is described as follows.

In the case of QoS mapping table management, a prefix for managing the QoS mapping table is set in the network equipment 155 in the network domain 145 as shown in FIG. That is, when the specific option value starts with 'M2M_' in the network bootstrap process by the M2M terminal, it is set to manage in the QoS mapping table. This can mean pre-configuration. 5 is a table illustrating an example of a QoS mapping table structure. M2M_HOME_MON_xxx in FIG. 5 may indicate M2M_HOME_SEC in FIG.

In the QoS remarking operation performed by the network equipment 155 of the ISP system, the QoS policy generated in the UE managed in the QoS mapping table is trusted and does not perform remarking. However, the QoS policy that is not managed by the QoS mapping table is not trusted, and remarks are performed with Best Effort.

The QoS policy determined by the IP address assignment system 150 of the ISP system by the Network Bootstrap process is transmitted to the M2M terminal or the M2M gateway terminal 130 such as the IP-CCTV 115 of FIG. And is applied to the terminal or the M2M gateway terminal. The M2M terminal or the M2M gateway terminal generates service or application data mapped to the applied QoS policy. However, after managing the QoS profile, the M2M gate terminal must generate data corresponding to the QoS mapped to the corresponding M2M terminal connected to the M2M gate terminal.

FIG. 6 is a diagram (information flow chart) for explaining an operation example of the QoS service providing system 100 to which the QoS service providing method of the ISP system shown in FIG. 2 or FIG. 3 is applied. FIG. 6 illustrates a method for marking with a relatively high QoS (high QoS) such as an M2M terminal 115 including DSCL (Device Service Capabilities Layer) and optionally a silver class (silver policy information) (Or set) the service flow of the PC. The M2M terminal 115 may include any one of the IP-CCTV 115 and the M2M terminal 125 shown in FIG.

Referring to FIG. 6, FIG. 2, FIG. 3 or FIG. 5, first, the network equipment 155 included in the access network sets a QoS rule such as a Gold Queue or a Silver Queue, 150) maps the type of the UE or the service type of the UE with the QoS policy.

Next, the M2M terminal 115 performs the following network bootstrap process. The M2M terminal 115 requests the IP address assignment system 150 via the network equipment 155 to assign an IP address with the DHCP option 60: M2M_SEC_xxxx. The network device 155 responds to the IP address allocation request of the M2M terminal 115 by using the QoS mapping table included in the network device 155 such as the QoS mapping table of FIG. Lt; RTI ID = 0.0 > 115). ≪ / RTI > In response to the IP address assignment request of the M2M terminal 115 through the network device 155, the IP address assignment system 150 may determine the DHCP option and determine the QoS policy (QoS service policy information) to be Silver have. The IP address allocation system 150 then provisions the QoS policy determined by the IP address and Silver to the M2M terminal 115 via the network equipment 155.

Next, the M2M terminal 115 enforces (or enforces) the QoS policy in response to the provisioning information of the IP address assignment system 150 so that the security included in the application or the service system 160 And requests the network equipment 155 for a security service connection to the security system (CCTV or SEC in FIG. 2). In response to the request, the network device 155 confirms the trust mapping through the QoS mapping table of the network device 155, such as the QoS mapping table of FIG. 5, it is possible to always guarantee the silver QoS priority even in the network congestion situation with respect to the Internet communication service between the security system 160 and the Internet service.

A personal computer (PC) whose QoS is marked as silver requests Internet service to the network equipment 155. The network device 155 responds to the request of the PC and confirms mismatch of the trust mapping through the QoS mapping table of the network device 155 such as the QoS mapping table of FIG. The QoS is remarked with Best Effort. As a result, in a network congestion situation, traffic (data) between the PC and servers in the network domain may be lost. The QoS policy of the PC may be stored (registered) in the QoS mapping table as best effort or not stored in the QoS mapping table.
