Intent-based networking and reactive forwarding performance comparison on resolving multi-link failure

This study adopted a different approach by leveraging forwarding mechanisms. Software-defined networking (SDN) had two scenarios for handling link failures: intent-based forwarding and reactive forwarding. This research focused on comparing intent-based forwarding and reactive forwarding in SDN-based networks. The study tested both forwarding mechanisms on three different topologies and deliberately disrupted one or more links to evaluate the failure resolution capabilities. The results indicated that intent-based forwarding excelled in recovery time, especially in topology C used in this study, for both single-link and multi-link scenarios. Therefore, for applications that required high-reliability service, intent-based forwarding was more recommended, despite having a more complex process compared to reactive forwarding.
