NSAF: An Approach for Ensuring Application-Aware Routing Based on Network QoS of Applications in SDN

Table 2

Key requirements of the NSAF.

ID	Requirements	Description
R-01	Application profile management	Collects and analyzes the application type and application requirements
R-02	NSLA management	Manages network service-level agreement (SLA) for applications
R-03	Network status monitoring	Monitors node and link information in the network topology
R-04	Application-specific situation awareness	Ascertains QoS violation of the network route using application profile and NSLA
R-05	Application-specific path calculation	Calculates and determines path according to the network status
