Abstract: Method, apparatuses, and computer program products provide for configuration of failsafe behavior for autonomous navigation. In particular, an active failsafe home is repeatedly established from a plurality of failsafe homes, and an autonomous vehicle is configured to travel to the active failsafe home when a communication fault occurs. An example method includes determining a location of the autonomous vehicle and determining whether a particular failsafe home of a plurality of failsafe homes associated with the autonomous vehicle satisfies a pre-determined visibility condition with respect to the location of the autonomous vehicle and one or more constraint areas. The method further includes, in accordance with a determination that the particular failsafe home satisfies the pre-determined visibility condition, establishing the particular failsafe home as an active failsafe home for the autonomous vehicle.

Abstract: SR-enabled network nodes capable of replicating and recombining data packets in a manner that enables reliable, low-latency communications. In an example embodiment, a replicator node transmits to a combinator node multiple copies of a payload over different respective network paths, with the SR headers of the corresponding packets each having a replication segment identifier or a respective SID stack that includes the replication segment identifier. The combinator node delivers/forwards to the corresponding application/destination only the first-to-arrive payload copy and discards any subsequent payload copies based on the replication segment identifier. Some embodiments may beneficially reduce latency and packet loss concurrently and consistently. For example, packet loss may be reduced due to the transmission of multiple copies of the same payload over multiple network paths. Effective latency may be reduced due to the selection of the first-to-arrive payload copy for delivery/forwarding.
