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.

Abstract: In a wireless network, such as a WiFi network, having a root node and at least one extender, as part of the execution of a factory reset of the root node, the root node automatically transmits a “clear configurations” message to each extender and, in response to receiving such message, each extender clears its configurations including any home SSIDs, any guest SSIDs, any gaming SSIDs, and any port-forwarding configurations. In this way, a factory reset of the root node can be used to prevent non-primary UEs from accessing the network using previous non-primary configurations.
