This comprehensive diagram provides an overview of the virtualization of the VDTN network model.
However, there are the challenges of mobility management, resource management, and network overhead management in the virtualization of the Internet.
With these goals in mind, one could think of several applications that can benefit from the virtualization of sensor network infrastructures.
This network leverages the virtualization of network functions and concepts.
Modern technologies such as software-defined networking (SDN) enable virtualization of the network, the ability to optimize paths, schedule transfer jobs, and the ability to contain data flows with specific security characteristics.
The characteristics required for multitenancy in wide-area networks are scalability to the large number of physical OpenFlow switches and applicability to the virtualization of multiple administration networks.
The relevant practices might include robust data encryption; two-factor authentication for customers and employees; the virtualization of networks at all levels, including applications and data; and adequate monitoring, so that breaches can be addressed quickly.
The AutoVFlow mechanism is suitable for the virtualization of multiple administrator networks, because AutoVFlow proxies manage the mapping of header values for virtualization autonomously.
This interface is used by the SDRAN controller to enforce different policies according to requests from the virtual operators and realize effective virtualization of the access network and resource, enable quick configuration of network parameters.
For example, VWNs encompass in the context of cellular networks, the virtualization of 4G/5G RAN[156], WiMAX BS[157], and LTE[158]; in a similar vein, virtualized abstractions have been proposed for WLAN environments such as the virtual NIC abstraction[159] and the virtual access point (AP) abstraction[160].
