The management device 1 includes a storage unit 11 and a control unit 12.

  The storage unit 11 is, for example, a read only memory (ROM) and a random access memory (RAM). The storage unit 11 stores various programs for causing the management device 1 to function. For example, the storage unit 11 stores a management program that causes the control unit 12 of the management apparatus 1 to function as an address assignment unit 121, an authentication unit 122, a priority reception unit 123, and a transmission unit 124 described later.

  The control unit 12 is, for example, a CPU (Central Processing Unit). The control unit 12 controls various functions related to the management apparatus 1 by executing various programs stored in the storage unit 11. The control unit 12 functions as an address assignment unit 121, an authentication unit 122, a priority reception unit 123, and a transmission unit 124 by executing a management program.

  The address assignment unit 121 assigns an IP address to the user terminal 4 in response to the user terminal 4 being connected to the network in the first base. In the present embodiment, the address assignment unit 121 assigns an IP address to the user terminal 4, but the present invention is not limited to this. For example, the first base-side CE router 3 may assign an IP address to the user terminal 4.

  When the use of the user terminal 4 is started, the authentication unit 122 accepts the user ID and the password, and authenticates the user. The storage unit 11 stores login information in which a user ID and a password are associated with each other. When receiving the user ID and the password from the user terminal 4, the authentication unit 122 authenticates the user by determining whether or not the user ID and the password are associated with each other in the login information.

  If the authentication unit 122 determines that the user ID accepted from the user terminal 4 is associated with the password during login, it determines that the authentication is successful, and determines that the user ID and the password are not associated. , It is determined that the authentication has failed. When determining that the authentication of the user is successful, the authentication unit 122 associates the IP address assigned to the user terminal 4 with the user ID and causes the storage unit 11 to store the IP address as address information.

  The priority receiving unit 123 receives, from the user terminal 4, the user ID and the priority related to the communication of the user. The priority receiving unit 123 associates the received user ID with the priority and causes the storage unit 11 to store the received user ID as priority information. The priority receiving unit 123 may receive, for example, the user ID and the priority from a management terminal (not shown) used by a manager who manages the network of the first base.

  The transmitting unit 124 transmits the address information and the priority information to the communication path setting device 2. For example, in response to the IP address included in the address information being updated, the transmitting unit 124 transmits the address information corresponding to the IP address to the communication path setting device 2. In addition, the transmitting unit 124 transmits the priority information corresponding to the priority to the communication path setting device 2 in response to the update of the priority included in the priority information.

[Configuration Example of Communication Route Setting Device 2]
FIG. 3 is a diagram showing the configuration of the communication route setting device 2 according to the first embodiment.
The communication path setting device 2 includes a storage unit 21 and a control unit 22.

  The storage unit 21 is, for example, a ROM, a RAM, and the like. The storage unit 11 stores various programs for causing the communication path setting device 2 to function. For example, the storage unit 21 causes the control unit 22 of the communication route setting device 2 to function as an address specification unit 221, a priority specification unit 222, a quality measurement unit 223, a route selection unit 224, and a route update unit 225 described later. Store the setting program.

  The control unit 22 is, for example, a CPU. The control unit 22 controls various functions related to the communication path setting apparatus 2 by executing various programs stored in the storage unit 21. The control unit 22 functions as an address specifying unit 221, a priority specifying unit 222, a quality measuring unit 223, a route selecting unit 224, and a route updating unit 225 by executing a route setting program.

  The address specifying unit 221 specifies the IP address of the user terminal 4 used by each of the plurality of users. The address specifying unit 221 receives the address information corresponding to the user from the management device 1 at the timing when the user terminal 4 accesses the management device 1 and the user starts using the user terminal 4. Identify the IP address of.

  The address identification unit 221 causes the storage unit 21 to store the address information received from the management device 1. The storage unit 21 stores an address table for storing address information of each of the plurality of user terminals 4. FIG. 4 is a diagram showing an example of the address table according to the first embodiment.

  The address specifying unit 221 reflects the received address information in the address table. For example, when the user ID included in the received address information is not stored in the address table, the address specifying unit 221 stores the address information in the address table. Further, when the user ID included in the received address information is stored in the address table, the address specifying unit 221 determines that the IP address associated with the user ID is the IP address included in the received address information. Update to

  The priority specifying unit 222 specifies the priority of communication of each of a plurality of users. For example, the priority specifying unit 222 specifies the priority by receiving the priority information transmitted from the management device 1 in response to the management device 1 receiving the priorities of the plurality of users. . Here, the priority is 10 levels of 1 to 10, 1 indicates the lowest priority, and 10 indicates the highest priority.

  The priority specifying unit 222 stores the priority information received from the management device 1 in the storage unit 21. The storage unit 21 stores a priority table storing priority information of each of the plurality of user terminals 4. FIG. 5 is a diagram showing an example of the priority table according to the first embodiment.

  The priority specifying unit 222 reflects the received priority information in the priority table. For example, when the user ID included in the received priority information is not stored in the priority table, the priority specifying unit 222 stores the priority information in the priority table. Further, when the user ID included in the received priority information is stored in the priority table, the priority specifying unit 222 includes the priority associated with the user ID in the received priority information. Update to the current priority.

  The quality measurement unit 223 measures the communication quality of each of the plurality of communication paths at predetermined time intervals. Specifically, when there are a plurality of PE routers to which a CE router can be connected, the quality measurement unit 223 measures the communication quality of the communication path between the CE router and each of the plurality of PE routers. In the example shown in FIG. 1, the quality measurement unit 223 is a communication path between the first base CE router 3 and the first base PE router 7A, the first base CE router 3 and the first base PE router 7B. The communication quality of the communication route between the first base CE router 3 and the first base PE router 7C is measured.

  For example, the quality measurement unit 223 causes each of the plurality of first base PE routers 7 to perform ping on the first base CE router 3. The quality measurement unit 223 indicates the response time from the transmission of the packet by the first base PE router 7 to the reception of the response packet as the execution result of Ping from each of the plurality of first base PE routers 7. Receive information The quality measurement unit 223 measures the communication quality of the communication path between each of the plurality of first base PE routers 7 and the first base CE router 3 based on the received information indicating the response time.

  The quality measurement unit 223 classifies the measured communication quality into any of a plurality of quality levels. For example, the quality level is one of five levels of 1-5, with 1 indicating the lowest priority and 5 indicating the highest priority. The quality measurement unit 223 distributes the measured communication quality to any of five quality levels based on a predetermined threshold.

  Also, the quality measurement unit 223 measures the throughput of each of the plurality of communication paths based on the data amount of the packet transmitted and received at the time of execution of Ping and the response time.

  The quality measurement unit 223 associates the measured quality level of the communication quality, the throughput, and the route identification information for identifying each communication route, and stores them in the storage unit 21 as communication quality information. FIG. 6 is a diagram showing an example of communication quality information according to the first embodiment. For example, as route identification information shown in FIG. 6, "7A-3" indicates a communication route between the first base PE router 7A and the first base CE router 3.

  The route selection unit 224 transmits the address of the user terminal 4 used by each of the plurality of users based on the communication quality measured by the quality measurement unit 223 and the priority specified by the priority specification unit 222. Or select the communication path of the communication to be the transmission destination.

  For example, the path selection unit 224 assigns users to communication paths with high communication quality in order from the user with the highest priority. Here, the route selection unit 224 is the sum of the predicted communication volumes of the plurality of users allocated to the communication route based on the throughput of the communication route measured by the quality measurement unit 223 and the predicted communication volumes of the plurality of users. Assign a user to the communication path so that the throughput of the communication path is not exceeded.

  For example, the quality levels and throughputs of the communication paths between the plurality of first base PE routers 7A to 7C and the first base CE router 3 are shown in FIG. 6, and the priorities of the plurality of users are Suppose that it is shown in FIG. Also, the predicted communication volume per second of the user with user ID “u001” is 100 Mbps, and the predicted communication volume per second of the user with user IDs “u002” and “u003” is 50 Mbps. Do.

  In this case, the path selection unit 224 selects the communication path between the first base PE router 7A and the first base CE router 3 as the communication path of the user whose user ID is "u001". Further, the route selection unit 224 selects the communication route between the first base PE router 7B and the first base CE router 3 as the communication route of the user whose user ID is "u002" or "u003".

  In addition, the path selection unit 224 reselects, at a predetermined timing, a communication path of communication in which the address of the user terminal 4 used by each of the plurality of users is the transmission source or the transmission destination. For example, the route selection unit 224 refers to the communication quality information stored in the storage unit 21 and, when determining that the quality level indicating the communication quality measured by the plurality of quality measurement units 223 has changed, re-selects the communication route. select. By doing this, the communication route setting device 2 can dynamically change the communication route according to the change of the communication quality.

  Further, the route selection unit 224 refers to the address information stored in the storage unit 21 and determines whether the IP address identified by the address identification unit 221 has changed. When determining that the IP address has changed, the route selection unit 224 reselects the communication route. Further, the route selection unit 224 refers to the priority information stored in the storage unit 21 and determines whether the priority specified by the priority specification unit 222 has changed. When determining that the priority has changed, the route selection unit 224 reselects the communication route. By doing this, the communication route setting device 2 can dynamically change the communication route in response to the change of the state of the user terminal 4.

  When the communication path is selected by the path selection unit 224, the path update unit 225 updates, based on the communication path, the routing information of the communication device that configures each of the plurality of communication paths. For example, the communication path between the first base PE router 7A and the first base CE router 3 as a communication path of a user whose network configuration is shown in FIG. 1 and whose user ID is "u001", the user ID It is assumed that the communication path between the first base PE router 7B and the first base CE router 3 is selected as the communication path of the user of “u002” and “u003”. In this case, communication paths corresponding to the user terminals 4A to 4C corresponding to the respective user IDs are as shown in FIG. The route update unit 225 updates the routing information of the first base CE router 3 and the second base PE router 8.

  The path update unit 225 updates, for example, the routing information of the communication of each of the plurality of user terminals 4 as the transmission source as shown in FIG. As shown in FIG. 8, when the IP address corresponding to the user ID "u001" is the transmission source, the first base-side PE router 7A is defined as the transmission destination device, and the user ID "u002" and "u003" are supported. When the IP address to be transmitted is the transmission source, it can be confirmed that the first base-side PE router 7B is defined as the transmission destination device.

  Also, after selecting the communication route as shown in FIG. 7, a failure occurs in the communication route between the first base PE router 7A and the first base CE router 3, and the quality level is from "5". It is assumed that it has changed to "1". Also, it is assumed that the quality levels and throughputs of other communication paths in this case are as shown in FIG. 6, and the priorities of a plurality of users are as shown in FIG. Also, the predicted communication volume per second of the user with user ID “u001” is 100 Mbps, and the predicted communication volume per second of the user with user IDs “u002” and “u003” is 50 Mbps. Do.

  In this case, the path selection unit 224 selects the communication path between the first base PE router 7B and the first base CE router 3 as the communication path of the user whose user ID is "u001". Further, the route selection unit 224 selects the communication route between the first base PE router 7C and the first base CE router 3 as the communication route of the user whose user ID is "u002" or "u003". In this case, communication paths corresponding to the user terminals 4A to 4C corresponding to the respective user IDs are as shown in FIG. The route update unit 225 updates the routing information of the first base CE router 3 and the second base PE router 8.

As described above, the communication route setting device 2 according to the third embodiment identifies the application being executed in the user terminal 4, and based on the priority associated with the identification information of the application in the storage unit 21. Then, the priority of the communication of the user who uses the user terminal 4 is specified. Then, when determining that there is a change in priority, the communication route setting device 2 determines the address of the user terminal 4 used by each of the plurality of users based on the measured communication quality and the specified priority. A communication path of communication to be a transmission source or a transmission destination is selected. By doing this, the communication route setting device 2 can set the communication route of the user based on the execution status of the application.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It is apparent to those skilled in the art that various changes or modifications can be added to the above embodiment.

  For example, in the above embodiment, the storage unit 21 of the communication path setting device 2 associates the user ID for identifying the user of the user terminal 4, the address information in which the IP address is associated, the user ID, and the priority. Although it was decided to store the priority information, it is not limited to this. For example, the communication path setting device 2 stores the priority information in which the department ID for identifying the department to which the user belongs, the address information in which the IP address is associated, the department ID, and the priority. The communication path may be selected for each department to which the user belongs.

  Further, in the second embodiment, the priority receiving unit 123 of the management device 1 receives from the user terminal 4 the user ID, the priority related to the communication of the user, and the time when the priority is applied. Not limited to this. The priority receiving unit 123 may receive a time slot to which the priority is applied instead of the time when the priority is applied. Then, the priority specifying unit 222 of the communication path setting device 2 stores, in the storage unit 21, priority information in which the user ID, time zone information indicating a time zone, and user communication priority in the time zone are associated. It may be stored, and the priority specifying unit 222 may specify the priority of each communication of the user in the current time zone based on the priority information stored in the storage unit 21.

  In addition, the specific embodiment of the distribution and integration of the devices is not limited to the one illustrated above, but all or part of the embodiments according to various additions or the like, or according to the functional load, in arbitrary units. It can be configured to be distributed or integrated functionally or physically.
