Cloud datacenters resource request development have altered resource allocation and management efficiency, presenting a pertinent research topic. Hence, we innovatively outline Virtual Physical Switch-Software Defined Network (VPS-SDN), an application-aware resource allocation method, an innovative model tenants portraying Virtual Datacenter (VDC) network requirements, plus network framework and uplink and downlink bandwidth. Contrasting hose abstraction, VPS-SDN engenders models resembling physical network, neither the TAG abstraction modeling the actual pattern of communication of applications. The VPS-SDN model leverage per-tenant network structure and bandwidth requirements concisely and flexibly depicting actual networks. VPS-SDN engenders a heuristic switch-centered Virtual Network (vNetwork) to Physical Network (pNetwork) mapping diagram, permitting tenants to run their applications using cloud networking to simulate an enterprise environment cloud datacenters, thereby promoting comparable outcomes. Simulation results show that our proposed scheme achieves high network utilization and enable the substrate network to satisfy much larger virtual networks.
