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.
1. A method comprising:
dynamically determining, via a processor, a link connecting two adjacent nodes of a loop in a communication network in accordance with a predefined criterion,
wherein determining the link comprises collecting link capacities of each link of the loop, and calculating the link for breaking the loop using the link capacities collected, the link being optimal with regard to the predefined criterion,
wherein calculating the link comprises:
computing, for each link in the loop, a minimum of an available capacity of a node when the loop is broken at that link,
identifying, for the loop, an overall maximum of the minimum available capacities calculated for each link, and
specifying, as the optimal link for breaking, the link whose minimum available capacity calculated corresponds to the overall maximum capacity identified; and
wherein the method further comprises causing the loop to be reconfigured so that the loop is broken at the determined link.
