A first logical link path and a second logical link path between two endpoints are identified. The first logical link path and the second logical link path comprise an OSI layer 5 link path from source to destination including intermediate network devices. The first logical link path and the second logical link paths include at least a different intermediate network device. A communications session is established between the two endpoints. Data packets for the communications session are communicated using the first logical link path. A metric indicative of a time of receipt of packets on the first logical link path is determined. Based on the metric, presence of a network condition at the communications network that is indicative of a performance degradation of the first logical link path is determined. In response, data packets for the communications session are communicated on the second logical link path.
