Title: LAYER-2 CONNECTION DEVICE, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD
Abstract:
Provided is a connection device capable of communication with an L2 switch such as one that does not use LAG, even when a plurality of links of differing communication quality are bundled. A traffic dispersion unit (103) determines a bulk port (102) for transmitting a packet that is received by a LAN port (101) and addressed to a device (1b). An SA-MAC rewriting unit (104) rewrites a MAC address of a device (1a) set as the transmission origin in the packet to the MAC address of the determined bulk port (102), and causes the packet to be transmitted from the determined bulk port (102). A packet transfer unit (108) rewrites the MAC address of the bulk port (102), which was set as the destination for the packet addressed to the device (1a) received from the bulk port (102), to a MAC address corresponding to an upper layer address of the device (1a) set as the destination of the packet, and causes the packet to be transmitted from the LAN port (101).
