at least one memory storing instructions, and
at least one processor configured to execute the instructions to;
receive sensor information from a sensor device that collects packets transferred between a wireless terminal and a first access point and between the wireless terminal and a second access point, the sensor information being generated based on the collected packets;
manage the first access point and the second access point in association with the wireless terminal when the wireless terminal performs communication with the first access point and the second access point by applying redundancy to a communication path; and
generate information regarding a communication state of redundant communication paths by using the sensor information regarding the first access point and the second access point.
2. The server device according to claim 1 , wherein the at least one processor is further configured to execute the instructions to manage a first BSSID used by the wireless terminal for communication with a first access point and a second BSSID used by the wireless terminal for communication with a second access point in association with each other.
3. The server device according to claim 1 , wherein the at least one processor is further configured to execute the instructions to combine first sensor information regarding a first communication path with the first access point and second sensor information regarding a second communication path with the second access point, average the first sensor information and the second sensor information, or select a maximum value or a minimum value of the first sensor information and the second sensor information, and generate information regarding the communication state.
4. The server device according to claim 3 , wherein, when the wireless terminal performs communication by switching between the first communication path and the second communication path, the at least one processor is further configured to execute the instructions to generate information indicating the number of times of switching in a predetermined period as information regarding the communication state.
5. The server device according to claim 3 , wherein, when the wireless terminal performs communication by switching between the first communication path and the second communication path, the at least one processor is further configured to execute the instructions to generate information indicating an establishment state of a wireless link in the first communication path or the second communication path that is not used for communication as information regarding the communication state.
6. A monitoring method in a server device, comprising:
receiving sensor information from a sensor device that collects packets transferred between a wireless terminal and a first access point and between the wireless terminal and a second access point, the sensor information being generated based on the collected packets;
managing the first access point and the second access point in association with the wireless terminal when the wireless terminal performs communication with the first access point and the second access point by applying redundancy to a communication path; and
generating information regarding a communication state of redundant communication paths by using the sensor information regarding the first access point and the second access point.
7. The monitoring method according to claim 6 , further comprising, when managing the first access point and the second access point in association with the wireless terminal, managing a first BSSID used by the wireless terminal for communication with a first access point and a second BSSID used by the wireless terminal for communication with a second access point in association with each other.
8. The monitoring method according to claim 6 , further comprising, when generating information regarding the communication state, combining first sensor information regarding a first communication path with the first access point and second sensor information regarding a second communication path with the second access point, averaging the first sensor information and the second sensor information or selecting a maximum value or a minimum value of the first sensor information and the second sensor information, and generating information regarding the communication state.
9. A non-transitory computer-readable medium storing a program that causes a computer to execute:
receiving sensor information from a sensor device that collects packets transferred between a wireless terminal and a first access point and between the wireless terminal and a second access point, the sensor information being generated based on the collected packets;
managing the first access point and the second access point in association with the wireless terminal when the wireless terminal performs communication with the first access point and the second access point by applying redundancy to a communication path; and
generating information regarding a communication state of redundant communication paths by using the sensor information regarding the first access point and the second access point.
