The storage unit 21 stores an address table that stores the address information of each of the plurality of user terminals 4. FIG. 4 is a diagram showing an example of an 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 identification unit 221 sets the IP address associated with the user ID as the IP address included in the received address information. Update to.

The priority specifying unit 222 specifies the priority of each communication 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 priority of each of the plurality of users. .. Here, the priority is a level of 10 levels from 1 to 10, where 1 indicates the lowest priority and 10 indicates the highest priority.

Update to the priority you have.

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 the 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 side CE router 3 and the first base side PE router 7A, and the first base side CE router 3 and the first base side PE router 7B. The communication quality of the communication path between the user and the CE router 3 on the first base side and the PE router 7C on the first base side is measured.

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

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

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

The quality measurement unit 223 associates the measured communication quality quality level with the throughput and the route identification information for identifying each communication route, and stores the measured communication quality information 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 the route identification information shown in FIG. 6, "7A-3" indicates a communication route between the first base-side PE router 7A and the first base-side 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 identification unit 222. Alternatively, select the communication path of the communication to be the transmission destination.

For example, the route selection unit 224 assigns users to communication routes having high communication quality in order from users having high priority. Here, the route selection unit 224 is the total of the predicted communication amounts of the plurality of users assigned to the communication path based on the throughput of the communication path measured by the quality measuring unit 223 and the predicted communication amount of each of the plurality of users. However, users are assigned to the communication path so as not to exceed the throughput of the communication path.

For example, the quality level and throughput of the communication path between the plurality of first base side PE routers 7A to 7C and the first base side CE router 3 are shown in FIG. 6, and the priority of the plurality of users is shown. It is assumed that it is as shown in FIG. Further, it is assumed that the predicted communication volume per second of the user whose user ID is "u001" is 100 Mbps, and the predicted communication volume per second of the user whose user ID is "u002" and "u003" is 50 Mbps, respectively. To do.

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

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

Further, the route selection unit 224 refers to the address information stored in the storage unit 21 and determines whether or not the IP address specified by the address identification unit 221 has changed. When the route selection unit 224 determines 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 or not the priority specified by the priority specifying unit 222 has changed. When the route selection unit 224 determines that the priority has changed, the route selection unit 224 reselects the communication route. By doing so, the communication path setting device 2 can dynamically change the communication path according to the change in the state of the user terminal 4.

When a communication route is selected by the route selection unit 224, the route update unit 225 updates the routing information of the communication device constituting each of the plurality of communication routes based on the communication route. For example, the network configuration is shown in FIG. 1, and the communication path of the user whose user ID is "u001" is the communication path between the first base side PE router 7A and the first base side CE router 3, and the user ID. As the communication path of the users of "u002" and "u003", it is assumed that the communication path between the first base side PE router 7B and the first base side CE router 3 is selected. In this case, the 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 CE router 3 on the first base side and the PE router 8 on the second base side.

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

Further, after selecting the communication path as shown in FIG. 7, a failure occurs in the communication path between the first base side PE router 7A and the first base side CE router 3, and the quality level starts from "5". It is assumed that it has changed to "1". Further, it is assumed that the quality level and throughput of other communication paths in this case are shown in FIG. 6, and the priorities of a plurality of users are shown in FIG. Further, it is assumed that the predicted communication volume per second of the user whose user ID is "u001" is 100 Mbps, and the predicted communication volume per second of the user whose user ID is "u002" and "u003" is 50 Mbps, respectively. To do.

In this case, the route selection unit 224 selects the communication route between the first base side PE router 7B and the first base side CE router 3 as the communication route of the user whose user ID is "u001". Further, the route selection unit 224 selects a communication route between the first base-side PE router 7C and the first base-side CE router 3 as the communication route of the user whose user IDs are "u002" and "u003". In this case, the 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 CE router 3 on the first base side and the PE router 8 on the second base side.
