1. An edge device comprising:
one or more User-to-Network Interface (UNI) ports;
a plurality of Network-to-Network Interface (NNI) ports;
a processing device; and
a memory device configured to store a computer program having instructions that, when executed, allow the processing device to:
provide an end-to-end network security on a Media Access Control (MAC) layer, the end-to-end network security defined by the MAC Security (MACsec) protocol, and
provide network path protection by enabling packet routing over multiple paths via the plurality of NNI ports on a network layer by enabling continuity of the MACsec across the plurality of NNI ports from the one or more UNI ports.
