Rerouting network traffic based on detecting offline connection

A method comprising:

• communicating, by processing circuitry of a first adapter device, with a router device in accordance with a communication protocol that is different than the Media Access Control Security (MACsec) protocol, wherein the router device is incapable of communicating in accordance with the MACsec protocol;
• establishing, by the processing circuitry, an encrypted connection in accordance with the MACsec protocol between the first adapter device and a remote device, wherein the processing circuitry is configured to receive information from the router device in accordance with the communication protocol and forward the information to the remote device in accordance with the MACsec protocol, and receive information from the remote device in accordance with the MACsec protocol and forward the information to the router device in accordance with the communication protocol;
• determining, by the processing circuitry, that the encrypted connection is offline;
• outputting, by the processing circuitry, a message to the router device that the encrypted connection is offline;
• and
• communicating, by the router device, with the remote device via a second adapter device configured to communicate in accordance with the MACsec protocol and bypass the first adapter device.

A non-transitory computer-readable medium comprising instructions for causing one or more programmable processors of a router device and a first adapter device to:

• communicate with the router device in accordance with a communication protocol that is different than the Media Access Control Security (MACsec) protocol, wherein the router device is incapable of communicating in accordance with the MACsec protocol;
• establish an encrypted connection in accordance with the MACsec protocol between the first adapter device and a remote device, wherein the processing circuitry is configured to receive information from the router device in accordance with the communication protocol and forward the information to the remote device in accordance with the MACsec protocol, and receive information from the remote device in accordance with the MACsec protocol and forward the information to the router device in accordance with the communication protocol;
• determine that the encrypted connection is offline;
• output a message to the router device that the encrypted connection is offline;
• and
• communicate with the remote device via a second adapter device configured to communicate in accordance with the MACsec protocol and bypass the first adapter device.
