Relay device and relay method

Japanese Patent JP6362424

B2

PROBLEM TO BE SOLVED: To switch a communication path without reducing bandwidth or causing billing.SOLUTION: Relay devices (gateways X and Y) are arranged in a base 10 connected with another base 20 via redundant communication paths 31, 32 and are equipped for the respective redundant communication paths. The relay devices (gateways X and Y) are an L2 transmission type and connected with a communication device (server 14) arranged in the base via a path selection device (L2 switch 13) that selects a path referring to a data link layer. If one of the relay devices is notified that it newly becomes active by switching of a communication path, it transmits a packet of which a transmission source is the MAC address of a communication device (client 23) included in the other base and of which a transmission destination is the MAC address of a relay device other than the relay device notified that it newly becomes active via the path selection device (L2 switch 13), thereby changing a path selected by the path selection device.
