Network virtualization may be used in application development and testing to mimic real-world hardware and system software. In application performance engineering, network virtualization enables emulation of connections between applications, services, dependencies, and end users for software testing.
In October 2012, a group of telecom operators published a white paper [4] at a conference in Darmstadt, Germany, on software-defined networking (SDN) and OpenFlow.The Call for Action concluding the White Paper led to the creation of the Network Functions Virtualization (NFV) Industry Specification Group (ISG) [5] within the European Telecommunications Standards Institute (ETSI).
Initially, network virtualization only involved the separation of the control plane and the forwarding plane (management and packet transmission) within networking devices like switches. This has shifted to include the totality of virtualizing a network, including how the network is programmed, administered, and deployed, be it hardware ...
Virtual eXtensible LAN (VXLAN) is a network virtualization technology that uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA-assigned destination UDP port number, [1] although many implementations that predate the IANA assignment use port 8472.
The Crossbow project software, combined with next generation network interfaces like xge and bge, enable network virtualization and resource control for a single system. By combining VNICs with features such as exclusive IP zones or the Sun xVM hypervisor, system administrators can run applications on separate virtual machines to improve performance and provide security.
A management component decides how communication stacks get composed and the scheduling scheme. To support decisions a management interface is provided to integrate the management system in software-defined networking contexts. NPV has been further investigated as a central element of LPWAN Internet of Things (IoT) scenarios.
OVN is a network virtualization platform that separates the physical network topology from the logical one. [2] Users are able to connect virtual and physical interfaces with logical switches and routers, regardless of the underlying physical topology. Users are also able to define security policies and load-balancing to these logical instances.
Network Virtualization using Generic Routing Encapsulation (NVGRE) is a network virtualization technology that attempts to alleviate the scalability problems associated with large cloud computing deployments. It uses Generic Routing Encapsulation (GRE) to tunnel layer 2 packets over layer 3 networks. [1] Its principal backer is Microsoft. [2]
