Dual WAN VPN
Internet has revolutionized the world and ushered in many changes in businesses practices, technology, and the interdependence between them. There has been an influx of many technological devices and concepts that are aimed at equipping businesses with continuous Internet connectivity, thereby setting up a regime where there will be no network outages that disrupt business. Recently coined terms such as Broadband, Wide Area Network(WAN), Local Area Network(LAN), Virtual Private Network(VPN), Firewall, etc. all converge at one point - to cater to the goal of redundancy, reliability, security, and speed in WAN connectivity. A Dual WAN VPN is one of the concepts that add value to connectivity and data transmission, most of all enabling organizations to securely access the Internet for information.
A Virtual Private Network is a network, which makes use of the public telecommunication infrastructure to connect nodes and provide secure access between an internal network and the Internet. WANs are used as a medium to channel data from a VPN using encryption and other security features, so that data is secure and only authorized users can have access to information. A VPN maintains security at all levels through its intense security processes and tunneling protocols (Layer Two Tunneling Protocol). This technology comprises two wide area network links, actuating redundancy and speed. While a WAN VPN makes use of a local connection to the Internet Service Provider (ISP), a Dual WAN-VPN utilizes two wide area network connections and transports secure data to an organization’s network.
A Dual WAN-VPN can leverage a local network connection through tunneling, which is then connected to two wide area network links for Internet connectivity. It is possible to securely extend Wide Area Networks to remote locations by securing network traffic using VPN technologies. This accelerates WAN application performance and maximized bandwidth utilization. Enhanced IPSec feature can be used in order to allow data encryption across WAN-VPNs or dual WAN-VPNs.
Based on varying redundancy requirements and circuits, different WAN-VPN configurations are deployed. Its configuration may consist of any of the following: primary connectivity with backup, without backup, and backup that uses a circuit for primary connectivity. Some of the complexities of these devices were solved when incorporating high-end technology solutions such as those offered by FatPipe Networks. Although it can provide security and extensive administrative flexibility, FatPipe products can further add value to this functionality and make it all the more efficient.
With increased bandwidth, latency issues can be resolved and a WAN-VPN supports and maintains connectivity at all times. This is a strong plus point, as it aids in meeting business continuity standards. It also renders wide scalability and high reliability options. This can be a cost-effective solution providing secure primary and backup connectivity to remote sites. It also prevents network outages, thereby enabling businesses to accomplish their operations at a constant pace. In the past few decades, business continuity has emerged as a crucial concept that ensures the smooth functioning in businesses. While a dual Wide Area Network VPN considerably reduces downtime and maintains security over data transmission, it is still susceptible to connectivity issues.
FatPipe Networks’ technology solutions are widely deployed in large companies that require the highest level of wide area network integrity and uptime. It offers an elegant, flexible solution for WAN redundancy and dynamic load balancing of inbound and outbound data traffic. FatPipe devices, through constantly monitoring the response time of each dataline, intelligently choose which one to send the traffic on, thereby enabling maximum bandwidth utilization.
As characteristic of this technology, security features are provided by FatPipe at a more refined level. FatPipe’s patented MPVPN technology provides reliable, redundant and secure WAN data transmissions. The WAN infrastructure is strengthened and paves way for effective business continuity and communications.
