COMMUNICATION SYSTEM, COMMUNICATION APPARATUS, AND COMMUNICATION METHOD

摘要

There is provided a communication apparatus including a hardware processor configured to: count numbers of transmissions and receptions of a measurement frame assigned between frames when a communication of an active system is performed, by an active system counter, count numbers of transmissions and receptions of the measurement frame when a communication of a standby system is performed, assign switchover indication information for indicating an occurrence of the switchover from the active system to the standby system, to the measurement frame to be transmitted to other communication apparatus, and measure a data loss based on a count value of the active system counter or the standby system counter, by excluding frames transferred during a period of time from a transmission of the switchover indication information to a reception of the reception indication information transmitted from the other communication apparatus which has received the switchover indication information, from a measurement target.

主权项

1. A communication system comprising:
a first communication apparatus capable of performing a switchover of a communication path from an active system to a standby system, and configured to include a first hardware processor configured to: count a number of transmissions and a number of receptions of a measurement frame assigned between frames transferred on the communication path when a communication of the active system is performed, by an active system counter, count the number of transmissions and the number of receptions of the measurement frame when a communication of the standby system is performed, by a standby system counter, measure a data loss based on a count value of the active system counter or the standby system counter, and assign switchover indication information for indicating an occurrence of the switchover from the active system to the standby system, to the measurement frame to be transmitted; and a second communication apparatus capable of performing a switchover of a communication path from an active system to a standby system, and configured to include a second hardware processor configured to: assign reception indication information for indicating a reception of the switchover indication information, to a measurement frame to be transmitted to the first communication apparatus according to reception, from the first communication apparatus, of the measurement frame to which the switchover indication information is assigned, wherein the first hardware processor measures the data loss by excluding frames which are transferred during a period of time from a transmission of the switchover indication information to a reception of the reception indication information, from a measurement target.
