摘要: A switch in a software-defined network (SDN) uses flow table for packet forwarding. The consists of entries decided by controller. As user requests with variety data types have been dramatically increasing, controller's CPU is overloaded to process those requests. users may not obtain real-time data. Furthermore, the control plane might be overflowed OpenFlow messages that correspond number can reduced scheme keep permanent switch. huge support forwarding function degrade other functions. This paper proposes reduce and generated proposed divides switches into several regional groups. It re-designs incorporated concept two multiprotocol label switching tags guide packets from sources destinations. One tag guides source an edge destination group. another local Performance evaluation shows 74% reductions entries, compared conventional keeps without inquiry Moreover, 81% reduced, inquires controller every time once request arrives at
