Application-aware traffic engineering in software-defined network

摘要: Software-defined Networking (SDN) is a network paradigm to resolve the challenges of traditional networks. SDN can utilize its concept control and data plane separation improve Quality Service (QoS) certain traffic efficiently. Because engineering in promising way satisfy requirement well, we propose an application-aware system that cooperates with Deep Packet Inspection (DPI). In system, port number DPI-based classification are used identify application or service flows. The improves QoS identified flows by distributing them multiple queues different priorities each switch port. A admin define mapping table between flow priority (queue) system. To demonstrate feasibility designed implemented constructing controller entities. results experiment shows increased throughput reduced packet delay for traffic.
