2 PIRC Sublayer in MAC Block Diagram

3 Network Diagram Stations A & B are protection group on the primary ring Station A is the “0” member and station B is the “1” member Stations C & D are protection group on the secondary ring Station C is the “0” member and station D is the “1” member

4 PIRC Sublayer Logic on the Path MAC  Client if (bit 40 of the RPR DA is set) then if (PG state is “both active”) then if ((hash modulo result) != (member type)) then discard frame else if ((MAC is on secondary ring) and (RPR SA is the mate MAC addr)) discard frame else forward frame else if (PG state is “self down” or “hold-off”) then discard frame else forward frame else forward frame
