Abstract
Systems and methods for ring protection switching in a network based on selectively blocking and unblocking a port include forwarding traffic via the port over a data channel that utilizes a first service identifier, wherein the data channel is routed in the network along a closed loop; and selectively blocking and unblocking traffic on the port to provide the ring protection switching over the closed loop, wherein the selectively blocking and unblocking is performed based on a management channel that utilizes a second service identifier that is a different type from the first service identifier.
