Hereinafter, a real-time entry permissible number management apparatus according to an embodiment of the present invention will be described.

FIG. 1 is a view schematically showing a network system 1 in which a real-time entry permission management apparatus 10 according to an embodiment of the present invention is used.

As shown in FIG. 1, the network system 1 according to the embodiment of the present invention includes a service server 100 and a real-

The real-time entry permissible number management device 10 includes a traffic control server 200 and a user environment-based control server 300.

The service server 100 is a server for allocating resources to user terminals 510, 520, 530,... Connected through the network 400 to enable service use. The service server 100 may be a general-purpose server.

The traffic control server 200 controls traffic of the user terminals 510, 520, 530, ... connected to the service server 100 through the network 400. [ That is, the traffic control server 200 accesses the service server 100 to the user terminals 510, 520, 530, ... according to the resource use state of the service server 100, the number of previous users, Or instructs to wait for connection. In this way, the traffic control server 200 can control the number of users of the user terminal 510, 520, 530, ... to the service server 100 according to the resource use state of the service server 100, Techniques for controlling traffic are well known and will not be described in detail here.

The user environment based control server 300 collects response time from each user terminal 510, 520, 530, ... connected to the service server 100 through the network 400, To the traffic control server 200, information on access allowance adjustment for controlling the access allowable number accessible to the service server 100 through the network 400 in real time. Here, the response time of the user terminals 510, 520, 530, ... is determined by the user terminals 510, 520, 530, ... transmitting a request signal for the service to the service server 100 through the network 400 Represents the time taken to receive a response signal from the service server 100. [ The response times of the user terminals 510, 520, 530, ... are collected when the user terminals 510, 520, 530, ... access the service server 100 through the network 400. A method for the user environment-based control server 300 to collect the response time of each of the terminals 510, 520, 530, ... will be described later in detail.

The traffic control server 200 adjusts the entry allowable number of the service server 100 according to the entry allowable number control information transmitted from the user environment based control server 300.

2, the user environment-based control server 300 includes a response time collection unit 310, a storage unit 320, a service quality determination unit 330, a traffic information collection unit 340, (350).

The response time collection unit 310 collects response time from the user's terminal 510, 520, 530,. There are various ways in which the response time collection unit 310 collects the response time for each user, and this method will be described later.

The storage unit 320 stores the response time of the user terminal 510, 520, 530, ... collected by the response time collection unit 310, that is, the response time of the user, ,...) Using the minimum value (MIN) and the maximum value (MAX). At this time, the response time zone set through the response time of the user's terminal 510, 520, 530, ... and the response time set to the minimum value and the maximum value in the response time zone, It should be clear that the number of services can be variously set according to the service number related to service number and the policy set by the user.

The service quality determination unit 330 determines the response time of the user terminal 510, 520, 530, ... collected in the response time collection unit 310 and the minimum value of the response time domain stored in the storage unit 320 And determines the service quality of the user terminal 510, 520, 530, ... using the maximum value. This service quality is determined to be good when the response time of the user terminal 510, 520, 530, ... is within the minimum value from 0, and is judged to be normal when it is between the minimum value and the maximum value. . Of course, it is also possible to divide the response time domain into a larger number of intervals rather than a minimum value and a maximum value to judge the service quality in various forms. However, in the embodiment of the present invention, It is assumed that it is divided into three quality domains.

The traffic information collection unit 340 collects the number of waiters waiting for connection from the traffic control server 200 to the service server 100 and the request amount information requesting the connection. The waiting number information may vary depending on the manner in which the traffic control server 200 implements the access permission and wait for the user terminal 510, 520, 530, ... to the service server 100, In addition to waiting, you can collect more waiting time. The request amount information is a sum of an entry request amount for entering the service server 100 through the network 400 and a request amount for requesting access to the service server 100 among waiters waiting to be connected to the service server 100 . It will be obvious to those skilled in the art that the configuration included in the request amount may vary depending on the manner of implementing the standby system.

The allowable number control unit 350 receives the service quality of the user's terminal 510, 520, 530, ... determined by the service quality determination unit 330 and the number of waiters collected by the traffic information collection unit 340, Information for controlling the number of allowed accesses in the service server 100 according to the amount information, and transmits the information to the traffic control server 200. The entering permission control information may be variously set according to the service policy of the service server 100. In the embodiment of the present invention, for convenience of description, when the allowable number control unit 350 determines that the service quality is good by the service quality determination unit 330 and there is a waiting number, the allowable number to the service server 100 is increased And if there are no waiters, it decides to reduce the entry allowance only if the requested amount is larger than the entry allowance.

If the service quality is determined to be normal, it is determined that the number of accesses is increased when there is a waiter, but it is determined that the number of accesses is decreased when there is no waiter.

In addition, when it is determined that the service quality is poor, it is determined that the unconditional entry allowable number is decreased. Here, increasing, maintaining, or reducing the number of allowable accesses to the service server 100 according to the status of the service quality, the number of waiters, and the requested amount can be more variously set according to the service policy of the service server 100 have.

In addition, the allowable number control unit 350 generates information indicating the degree of control of the entering allowable number together with the entering allowable control information, that is, information on the allowable entering control degree, based on the service quality of the user terminal 510, 520, 530, To the traffic control server (200). For example, when it is determined that the quality of service of the user terminal 510, 520, 530,... Is good, the degree of goodness will vary depending on the response time of the user terminal 510, 520, 530,. That is, although the response time is smaller than the minimum value, there will be a difference in the actual response time. In this case, if the response time is smaller, the degree of entry allowance adjustment will be set so that the entry allowable number can be further increased.

The standby management unit 210 manages the user terminals 510, 520, 530,... That are not allowed to access but are waiting for connection even though the service server 100 requests the connection. Therefore, the wait management unit 210 can transmit the number of waiters, which is the number of the user terminals 510, 520, 530, ... waiting for connection, to the user environment based control server 300.

The traffic control unit 220 determines the connection traffic of the user terminals 510, 520, 530, ... to the service server 100 according to the resource use state of the service server 100, . That is, the traffic control unit 220 controls the connection of the user terminals 510, 520, 530, ... to the service server 100 according to the resource use state of the service server 100, Or controls the connection wait. At this time, the user terminals 510, 520, 530, ... waiting for connection are controlled to be managed through the standby management unit 210. Also, the traffic control unit 220 may transmit the connection request amount to the user environment-based control server 300 as the request amount information.

The allowable number control information receiving unit 230 receives the allowable water control information and the allowable water control extent information transmitted from the user environment based control server 300. [

The entry allowance control unit 240 adjusts the entry allowable number used in the traffic control unit 220 in real time according to the allowable water control information and the allowable water control degree information received by the water control information receiving unit 230. [

Accordingly, the traffic control unit 220 can control the network 400 based on the entry allowable number adjusted in real time according to the response time of the user terminals 510, 520, 530, ... collected by the user environment based control server 300 The traffic of the user terminals 510, 520, 530, ... connected to the service server 100 can be controlled.

As described above, according to the embodiment of the present invention, when a request to the service server 100 for a user's network service is busy, It is possible to protect resources and provide a smooth service to users.

Further, in the embodiment of the present invention, according to the service quality state of the user, which is represented by the user environment on the user terminal (510, 520, 530, ...) It is possible to provide a stable network service which can be easily sensed by the user according to the user environment by adjusting the entry allowable number to the server 100 in real time.

Hereinafter, a method for managing a real-time entry allowable number based on a user service quality according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 8 is a flowchart of a method for managing a real-time entry allowable number based on a user service quality according to an embodiment of the present invention. Prior to the description, the previous user-specific response time information is stored in the storage unit 320 of the user environment-based control server 300, and based on the response time information, the response time zone and the minimum value And the maximum value are stored.

Referring to FIG. 8, the response time collection unit 310 collects the response time of the user's terminal 510, 520, 530,..., The response time of the user (S100). At this time, the response time collection unit 310 can collect the response time of the user's terminal 510, 520, 530, ... through the user's terminal 510, 520, 530, have.

Next, the service quality determination unit 330 determines the user service quality using the minimum value and the maximum value of the response time zone stored in the storage unit 320 with respect to the response time collected by the response time collection unit 310 (S110). These quality of service will be judged as good, moderate and bad.

Next, the traffic information collecting unit 340 collects information on the number of queues waiting for connection from the traffic control server 200 to the service server 100 and request amount information requesting connection (S120).

The allowable number control unit 350 controls the service server 100 based on the service quality of the user determined by the service quality determination unit 330 and the number of waiters and the request amount information collected by the traffic information collection unit 340, (S130). ≪ / RTI >

Then, the allowable number control unit 350 sets the entry allowable control degree information according to the service quality, the number of waiters and the requested amount for each user, and transmits the control information to the traffic control server 200 (S140).

Therefore, the traffic control server 200 adjusts the entry allowable number of the service server 100 according to the entry allowable number control information and the entry allowable control degree information transmitted from the allowable number control unit 350, (S150).

The process of determining service quality per user in step S110 will be described in more detail with reference to FIG.

FIG. 9 is a flowchart illustrating a process of determining a service quality per user shown in FIG.

9, if the response time collected by the response time collection unit 310 is smaller than the minimum value MIN (S111), the service quality determination unit 330 determines that the service quality of the corresponding user is good S112).

However, if it is determined in step S111 that the response time per user is equal to or greater than the minimum value MIN, it is determined whether the response time per user is less than the maximum value MAX in step S113. The service quality of the user is determined to be normal (S114).

If the response time per user is equal to or greater than the maximum value MAX in step S113, the service quality of the corresponding user is determined to be bad in step S115.

Next, a process of determining the entry allowable number adjustment of the service server 100 in step S130 will be described in more detail with reference to FIG.

FIG. 10 is a flowchart of a process of determining the entry permissible number adjustment of the service server 100 shown in FIG.

10, first, the allowable number control unit 350 determines whether the request amount, which is information collected by the traffic information collection unit 340, is smaller than a preset default value (S1310). If the request amount is larger than the default value, It is determined whether the quality of service judged by the quality judging unit 330 is good (S1320).

If it is determined that the service quality is good, the permissible number control unit 350 determines whether there is a waiting party based on the number of waiting queues (information collected by the traffic information collecting unit 340) (S1330). If it is determined that there is a waiting queue It is determined to increase the entry allowable number of the service server 100 (S1340).

If it is determined in step S1330 that there is no waiting person, it is determined whether the request amount is larger than the already entered allowable number (S1350). If it is determined that the requested amount is larger than the entering allowable number, (S1340). However, if the request amount is less than the entry allowable number, it is determined that the entry allowable number is decreased (S1370).

If it is determined in step S1320 that the service quality is not good, it is determined whether the service quality is normal again (S1380). If it is determined that the service quality is normal (S1390) .

If it is determined that there is a waiting person, the allowable number control unit 350 determines to increase the entry allowable number (S1400).

However, if it is determined that there is no waiting queue or the requested amount is smaller than the default value in the step S1310 or the service quality is not normal in the step S1380, it is determined to decrease the entering allowable number (S1410) .

Thereafter, the information determined in the above steps S1340, S1360, S1370, S1400, and S1410 is set as entry allowable control information (S1420).

In the above description, when the traffic control server 200 controlling the traffic of the service server 100 uses the idle mode for the user terminals 510, 520, 530, ... connected to the service server 100 The technical scope of the present invention is not limited thereto but may be applied to a server or a switch for controlling traffic to user terminals 510, 520, 530, ... connected to the service server 100 in various ways .

11, in the network system 2, the traffic control server 600 of the access allowance management apparatus 20 is connected to the service server 100 through a user terminal (for example, 510, 520, 530, ...), instead of using the waiting method, the traffic is controlled in such a manner that the connection is permitted when the number of access requests increases within the entry allowable number but is waited for requests exceeding the entry allowable number Server. For the traffic control server 600, the user environment based control server 700 checks the response time of the user terminals 510, 520, 530, ... to determine the service quality. If it is determined that the service quality is good, The access control unit 601 determines that the access control unit 600 determines that the access quality is poor and determines that the access control unit 600 determines that the access quality is poor, It is possible to adjust the entry allowable number of the server 100.
