Segregation and isolation of mission critical devices and services are among the main security concerns in cloud computing environments. Private Virtual LAN (PVLAN) offers the ability to efficiently support segregation and isolation among end devices. Link aggregation on PVLAN promiscuous ports reduces the risk of single point of failure for the entire PVLAN network. This research focuses on improving security and availability of nodes within the PVLAN domain and layer three devices by combining multiple PVLAN promiscuous ports as a single logical port using Software Defined Networking protocols. Our approach enables cloud platform to implement PVLAN by incorporating link aggregation to extend and support PVLAN features for optimal load balancing and path selection of inbound and outbound traffic. It also helps to reduce network inefficiencies which might occur from multiple traffic utilizing a single communication uplink. Simulation results show the effectiveness of our approach.
