 Replication and elimination works by spreading the data across several explicit paths and reassembling them in-order near the destination.Sequence number or timestamp is added to DetNet flow or transport protocol packet, then duplicate packets are eliminated and out-of-order packets are reordered, based on sequencing information and transmission logs, 
Adhering to the flow latency constraints also imposes constraints on misordering, as out-of-order packets impact the jitter and require additional buffering.Different path lengths also require additional buffering to equalize the delays and ensure bandwidth constrains after failure recovery.
