Methods, devices and systems for determining a target path in a network
Aspects of the subject disclosure may include, for example, embodiments and a method. The method includes iteratively providing messages to each Node Processor. Each Node Processor represents a node of a group of nodes. The iteratively providing of the messages comprises providing first messages. Each first message includes a cost associated with a path of nodes visited by each first message. A selected path is obtained from each node having a lowest cost of a group of common endpoint costs for paths having common endpoints. A next group of messages includes the selected path. The iteratively providing of the messages results in selected paths. Also, the method include determining a target path from a remaining path. Other embodiments are disclosed.
