Embodiments of the present disclosure describe a system and method for dynamically duplicating network packets onto a reliable link. Network devices can be connected by a primary link and by a secondary link. As the network quality of the first link degrades, the system can adaptively duplicate network packets onto the second link. As a high priority link, the secondary link can have less total bandwidth when compared to the primary link. Accordingly, all the traffic traversing the primary link may not be able to be duplicated onto the secondary link to preserve network reliability when the quality of the first link degrades. The present solution can effectively manage the bandwidth of the secondary link and set duplication rates that control the duplication of the packets onto the secondary link.
