NSAF: An Approach for Ensuring Application-Aware Routing Based on Network QoS of Applications in SDN
Table 6
Execution time of the NSAF.
| Framework element | Execution time |
| Collecting network status information | Collect network status information from the SDN controller every 10 s | Determining application QoS violations | Perform within 0.4 s to derive results | Route discovery to meet application QoS | Dijkstra’s algorithm: calculate one path within 0.3 s; genetic algorithm: derive various paths satisfying the QoS within 5 s |
