Abstract

A loop protection mechanism including dynamically determining a link connecting two adjacent nodes of a loop in a communication network in accordance with a predefined criterion, and reconfiguring the loop so that the loop is broken at the determined link which is an optimal link in terms of the predefined criterion. The breaking of the loop enables for example to utilize loop-free technologies (e.g. Ethernet) in a physical loop architecture.
