As you may know, ITU-T SG15 has previously approved G.8031 – Ethernet Linear Protection
Switching. At our June 2007 SG15 plenary, an amendment to G.8031 was consented.
The scope of the G.8031 Amendment is to add enhancements about response to EXER and DNR,
and the location of protection switching process. It also presents additional descriptions about
management information (MI) signals.
Q9 suggests that the protection mechanisms of G.8031 may be useful to consider in your
development of P802.1Qay.
