1. A method, comprising:
identifying traffic received at an endpoint in a network having a reactive path selection policy defining actions to apply in transmitting a plurality of different types of received traffic from the endpoint;
determining one or more actions of the actions that are applicable in managing transmission of the traffic from the endpoint;
reactively selecting, by the endpoint, a path of a plurality of paths from the endpoint for transmitting the traffic from the endpoint based on the one or more actions, comprising:
dropping the traffic in response to lack of valid available path to transmit the traffic;
applying, when a valid path is available, a path loss action to the traffic in response to the presence of a path loss action in the reactive path selection policy; and
forwarding, in the absence of further eligibility criteria limiting forwarding of the traffic, any traffic remaining to be sent after the applying.
