Abstract
The present disclosure provides for a loop avoidance technique that implements an upstream neighbor check to detect any forwarding inconsistencies. When a message is received from a neighbor routing element, an upstream neighbor check is performed to determine whether the neighbor routing element is an upstream neighbor toward a content provider of a datastream identified in the message. If the check determines that the neighbor routing element is not an upstream neighbor, then a forwarding inconsistency is not detected. If the check determines that the neighbor routing element is an upstream neighbor, then a forwarding inconsistency is detected.
