SCALABLE VIRUTAL NETWORKS IN SDN-BASED ETHERNET NETWORKS USING VLANS

摘要

Various embodiments are related to a kind of method, equipment, and machine-readable storage medium includes: the instruction for receiving a configuration request from an edge device, wherein configuration request identifies a traffic flow in addition to edge device between at least two end devices; For distributing the instruction of Virtual Local Area Network identifier to traffic flow; Instruction is used to configure the given VLAN identifiers of edge device addition to outgoing frame associated with traffic flow, and wherein outgoing frame is the frame that will be propagated by edge device to a core network. Various embodiments also comprise at least one the additional edge device for removing VLAN identifiers from incoming frame associated with traffic flow in distribution VLAN identifiers for instruction configuration response below, and wherein incoming frame is the frame for having already passed through at least one core node of core network.
