Our focus is on implementation and validation, not just theory. We have three main contributions. First, we implemented and deployed a GNS3-Mininet hybrid testbed for realistic network slicing validation. Second, we implemented and experimentally validated a RESTCONF-based automated fault detection and dynamic path recovery mechanism. Third, we functionally validated VLAN-based slice isolation and seamless traffic rerouting during node failures. The key differentiator of our work is that this is not just a theoretical framework - we built a proof-of-concept prototype that demonstrates automatic slice recovery without any manual intervention. |
