A novel frame switching model based on virtual MAC in SDN

Abstract MAC address spoofing has plagued LAN communication for a long time. Many attacks use it as springboard to carry out subsequent attacks. The main reason this kind of attack is the exposure address. If source node can be hidden during frame forwarding, effectively prevented. This study proposes virtual switching (VMS) solution problem. VMS uses multi-address hopping technology make change continuously in forwarding process. Its unique generation format makes other nodes unable record or speculate real node, so cannot launch an attack. Experiments show that close typical SDN switches terms delay, throughput, and overhead higher security level.
