Network virtualization (NV) creates orderly, virtual networks which can be decoupled in the underlying network hardware to make sure the network can integrate with and support environments that are virtual.
With virtualization, businesses are able to benefit from agility and the efficiencies of software-based storage and compute resources.
Virtualization is the capability to model a hardware platform, including storage device, a server or network resource . All the functionality is split in the hardware and modeled as a "virtual case," using the capability to function just like the conventional, hardware option would. Obviously, someplace there's host hardware supporting the virtual examples of the resources, yet this hardware may be general, off the shelf platforms. Additionally, one hardware platform may be used to support machines or multiple virtual devices, which are not difficult to spin down or up as needed. Because of this, an option that is virtualized is usually a lot more mobile, scalable and cost effective when compared to a conventional hardware-based option.
Virtual Extensible LAN (VXLAN) is a network virtualization technology that attempts to ameliorate the scalability problems connected with large cloud computing deployments. It uses a VLAN- like encapsulation technique to encapsulate MAC-established OSI layer 2 Ethernet frames within layer 4 UDP packets, using 4789 as the default IANA-assigned destination UDP port number.[1]
VXLAN is an evolution of efforts to standardize on an overlay encapsulation protocol. Scalability increases up to 16 million rational networks and allows for layer 2 adjacency across IP networks. Multicast or unicast with HER (Head End Replication)[2] is utilized to flood rat (broadcast, multicast unknown destination address,) traffic.
The VXLAN specification was initially created by VMware, Arista Networks and Cisco.[3][4] Other backers of the VXLAN technology contain Huawei[5], Broadcom, Citrix, Pica8, Cumulus Networks, Dell, Mellanox[6] OpenBSD,[7] Red Hat[8] and Juniper Networks.
