Title: Failure recovery method and system of controlled apparatus in system in which control apparatus and controlled apparatus are connected
Inventor: NAGANO TOMOYUKI
IPC: H04L45/586
Filed: 2019-06-27
Abstract: To provide a technique for recovering without causing a communication error even if a mismatch of session information occurs between a control apparatus and a controlled apparatus due to a failure occurred in the controlled apparatus.SOLUTION: A controlled apparatus 11 is duplexed by an active function unit and a standby function unit. A control apparatus 12 transmits a request signal including a sequence number that is incremented for each transmission to the controlled apparatus. As an asynchronous method, after the active function unit of the controlled apparatus replies an acknowledgment signal including the sequence number to the control apparatus, the active function unit duplicates communication establishment information and the sequence number to the standby function unit. When a failure occurs in the active function unit of the controlled apparatus, the standby function unit transmits the sequence number stored by itself to the control apparatus. The control apparatus transmits, to the standby function unit of the controlled apparatus, a deletion request for deleting the communication establishment information up to the sequence number stored in the control apparatus itself which is later than the sequence number received from the standby function unit of the controlled apparatus.SELECTED DRAWING: Figure 3
