This read-only Gauge32 reports the current best one-way time (BOWT), in milliseconds, in the receive direction for this VPath. An admin uses this to understand the best-case latency for traffic arriving from a specific remote site, helping assess whether that site can support latency-sensitive inbound applications. For example, an increasing best one-way receive time from a branch signals the network path from that site is degrading even in its best case.
