Data network virtualization (DNV) is a well-emerging data infrastructure environment, consisting of data center network topology, virtualized data center and traditional ISP. DNV is described by the network topology, routing and protocols, is a collection of virtual hardware networking resources. DNV is organized in a tree-like topology connecting to consecutive k-pods for k/2 edge switches: making complex aggregation switch topology, provides virtual networks consisting virtual nodes and virtual links: the propagation delay between virtual nodes becomes valuable when data virtual networks is congested with data, multi-packet forwarding schemes are used to spread the data among different virtual network paths: presence of fault-packet forwarding between network nodes are intolerance and service migration is required to balance the data load among the data virtual nodes. This paper, presents a switch hierarchical provider network which allows each data virtual nodes providing a separate logical DN routine to reduce the propagation delay through virtual-hierarchical topology utilising complex multi-path topology reducing switching complexity, and proposed traffic congestion-less schemes to reduce the fault-tolerance and load sharing. Our model evaluates a network virtualization infrastructure addressing the real word DNV, critical analysis of network level routing algorithm and data virtualization solution to deploy DNV platforms with different platforms.
