Abstract
Preventing transmission loops in a ring network that utilizes label switching involves generating right side and left side ring packets from an ingress packet and setting right and left TTL values for the packets that prevent the packets from traveling on the same transmission link. Setting the right and left TTL values of the ring packets to values that prevent the packets from traveling on the same link transforms the physical topology of the ring into a logical arc. In an embodiment, the logical arc established by a network node can be dynamically rotated in response to various network conditions to avoid packet transmissions on a particular link of the ring network.
