Dear authors of draft-cheng-mpls-tp-shared-ring-protection_04,

Section 5.1 states that RPS requests are required to be sent in both directions. Does this mean on the paired working/protection paths (RcW/RaP or RaW/RcP), or on the clockwise and anti-clockwise protection paths (RcP/RaP)?

I presume the former, although this is different from linear APS in which only the protection path carries the coordination protocol.

Thanks,
Spence
