For figure 2 example SRAD operation can be made as followings;
Node F calculates the BER of each route and selects the route with the lowest BER (which is A-B-C-F) as the first candidate route, then compares the following routes with the first route:
A-B-D-F
A-E-D-F
A-E-D-B-C-F
Node F selects the route of A-E-D-F as the second route for the connection pair A-F because this route has no common node with the first route A-B-C-F. Later, node F sends two RoC frame copies, one into each route to confirm the route selection.
Thereafter, node A duplicates each frame that needs to send it to node F and send these copies out, one to each route (to node B and node E).
