摘要: Software-Defined Networking (SDN) controllers are nowadays expected to manage large infrastructures and services in a practical, efficient, optimized way. To achieve such control, SDN networks should increase the automation of orchestration functions fullfil both service network management lifecycles. However, applications have stringent resource demands that orchestrators need honor. Most available focus on high-level approaches rely exclusively Northbound API (NB-API). A few strategies also been designed optimize controllers’ internal mechanisms through features enabled by Southbound (SB-API). solutions do not optimal information delivery orchestrator, crucial property provide prompt feedback response events, potentially drive self-healing auto-scaling properties. address need, we present NOTORIETY, an system provides abstraction for real-time controller event message handling. NOTORIETY is able maximize capabilities including innovative processing delivering information. NOTORIETY’s design consists empower SDN-controlled entities applying filtering rules efficiently control data flows provided controller. We implemented testbed assess our proposal following guidelines RFC 8456, benchmark its performance over three (OpenDaylight, ONOS, Floodlight). The evaluation results reveal effectiveness reducing execution time requests, load processing, overall marshaling volume several scenarios.
