Virtual Router Market: Up-to-Date Analysis of Latest Trends in Market

The market for virtual routers is primarily being driven by the growing popularity for software defined networking (SDN) and NFV globally. Such growth in NFV and SDN popularity has led to development of several advanced virtual router software solutions. These solutions allow for encapsulation of traffic through IP based tunnels and thus utilize an ‘overlay’ approach. Also several virtual routers have penetrated the market, which has Wide Area Networking (WAN) applications. Also, these advanced virtual router solutions can be installed in industry standard hardware, allowing for wider applications.

Virtual routers refer to a routing framework, based on software, which acts a normal hardware router. When virtual router software is installed in a device, such as a laptop or a server, it utilizes the hardware of the host to perform the network and packet routing functionalities, performed by a general router. Each virtual router is identified through a unique virtual router identifier, which is present at the last byte of the address. To improve the reliability of the network, virtual routers may be implemented by the Virtual Router Redundancy Protocol (VRRP).

The VRRP functions to automatically assign to a participating host, any available Internet Protocol (IP) router. Virtual routers thus enables virtual routing, a form of Network Functions Virtualization (NFV). Virtual routing instances are independent in nature and hence allows for overlapping of IP addresses, without any conflict with each other. Virtual routers are software which can be run on commercial off-the shelf (COTS) hardware and enable the hardware to function like a general hardware based network appliance.

Virtual routing enables the free relocation of routing functions across a network, since IP routing function is liberated from any specific software. In case of basic routing functions, addition of virtual router software to a commodity server allows the server to function as a router. In complex and advanced distributed routing environments, parts of the virtual router can be moved across the whole network, while being controlled from a centralized control location. From such an evolution it can be inferred that routing functions can be dynamically configured or adapted to the network needs. Open source emerging technologies are being designed to enable the routing functionalities to be integrated into software solutions and thus allowing for distribution throughout the network.
