1. A method comprising:
determining, by a network node for a flow, a remaining survival time for the flow;
determining, by the network node, a plurality of different reliability targets,
determining, by the network node, reliability target information, wherein the determining, by the network node, the plurality of different reliability targets is based on at least a portion of the reliability target information for the flow, and each reliability target of the plurality of different reliability targets is associated with a different value or a different range of values of the remaining survival time for the flow,
wherein the reliability target information comprises at least one of:
information identifying a target packet error ratio (PER) for each of a plurality of values or ranges of the remaining survival time for the flow;
a maximum or minimum reliability target after the remaining survival time for the flow is zero or has expired; and
a maximum allowed PER after the remaining survival time for the flow is zero or has expired, where the remaining survival time for the flow is zero or has expired when an elapsed time, during which one or more consecutive packet transmission errors for the flow have been detected, is greater than or equal to the remaining survival time for the flow; and
selecting, by the network node, a next reliability target, of the plurality of different reliability targets, for a next packet transmission for the flow based on the remaining survival time for the flow.
