APS
The APS module implements the protocol and linear protection switching mechanisms for point-to-point VLAN-
based ETH SNC (Subnetwork Connections) in Ethernet transport networks. The APS (Automatic Protection
Switching) protocol is used to ensure that switching is done bidirectionally in the two ends of a protection group,
as defined in ITU-T G.8031.
This Recommendation specifies linear 1+1 protection switching architecture and linear 1:1 protection switching
architecture. The linear 1+1 protection switching architecture operates with either unidirectional or bidirectional
switching. The linear 1:1 protection switching architecture operates with bidirectional switching.
