A Dual-Node Interconnection (DNI) PW is provisioned between the dual-homing Provider Edge (PE) nodes for carrying traffic when failure occurs in the Attachment Circuit (AC) or PW side. In order for the dual-homing PE nodes to determine the forwarding state of AC, PW and the DNI PW, necessary state exchange and coordination between the dual-homing PEs are needed. The PW dual-homing local protection mechanism is complementary to the existing PW protection mechanisms.}, }
