Abstract
Aspects of a method and system for tunneling MACSec packets through non-MACSec-enabled nodes are provided. In this regard, aspects of the invention may be utilized for transmitting MACSec Ethernet packets over MACSec and/or non-MACSec-enabled network nodes. In one embodiment of the invention, additional header information may be inserted into a MACSec packet before transmitting the MACSec packet to a non-MACSec-enabled node. Accordingly, aspects of the invention may remove the additional header information from a packet received from a non-MACSec-enabled node to distinguish the packets comprising inserted additional header information, which may comprise a distinguishing Ethertype.
