NSAF: An Approach for Ensuring Application-Aware Routing Based on Network QoS of Applications in SDN
Table 7
Comparison with the related studies.
| | Criteria | Interactive monitoring [28] | MonSamp [29] | PayLess [30] | NSAF |
| | Monitored targets | SDN controller and device | Traffic pattern | Application QoS | Application QoS and network path that satisfy application QoS |
| | Application QoS monitoring aspects | How to monitor QoS | Registration of the user traffic profile (configuration parameter setting) | Flow sampling application (switch flow rule) | Monitoring request object creation (specification) | NSLA based on the ontology (binding value at the ontology) | | Route control with QoS | Not supported | Feedback from the flow sampling application | Not supported (only monitoring) | Route control using NSAF | | How to ensure QoS | Not supported (visualization support about the monitoring result) | Not presented | Not presented (statistical result about monitoring) | (i) QoS violation detection using the ontology
(ii) Network routing with Dijkstra’s algorithm and GA considering QoS |
