Claim 9:
10. An apparatus, comprising:
one or more interfaces to communicate with a Layer-2 mesh;
a processor coupled to the one or more interfaces and configured to execute one or more processes; and
a memory configured to store a process that is executable by the processor, the process when executed configured to:
obtain a frame sent by a source toward a destination via the Layer-2 mesh;
make a classification of the frame;
modify, based on the classification, the frame to include a header associated with a virtual overlay for the Layer-2 mesh and to include a trailer that comprises a sequence number of the frame, an identifier for the source of the frame, and a unique flow identifier; and
send the frame modified by the apparatus to the virtual overlay toward the destination, wherein the frame is replicated along different paths in the virtual overlay and wherein a node in the virtual overlay performs deduplication with respect to two or more copies of the frame based on the trailer.
