1. A method comprising:
determining path-specific delay variations in a computer communication network between a time-sensitive nexus node and a plurality of time-sensitive non-nexus nodes;
determining, by the time-sensitive nexus node based on the path-specific delay variations, a plurality of copy-specific delay alignment compensations for a plurality of copies of a multi-destination communication packet, wherein the plurality of copies of the multi-destination communication packet is to be sent by the time-sensitive nexus node to the plurality of time-sensitive non-nexus nodes respectively;
using, by the time-sensitive nexus node, the plurality of per-copy delay alignment compensations to perform a plurality of per-copy delay alignment operations with respect to the plurality of copies of the multi-destination communication packet;
sending, by the time-sensitive nexus node, each copy of the multi-destination communication packet in the plurality of copies of the multi-destination communication packet to a respective time-sensitive non-nexus node in the plurality of time-sensitive non-nexus nodes after a respective per-copy delay alignment operation in the plurality of per-copy delay alignment operations is performed for the copy of the multi-destination communication packet.
