Business continuity is a concept that has emanated as a pivotal point for businesses in the technological arena. Enterprises and government organizations consider business continuity and disaster recovery planning as necessary requirements. The Wide Area Network (WAN), a geographically distributed telecommunication network, enables users around the globe to effectively share and transmit data. It allows businesses to carry out information transaction and business operations. A robust WAN infrastructure is a prerequisite of companies to conduct their business without disruptions. WAN backups are set up in the network infrastructure of these companies to ensure support for business continuity. The capability of a system to automatically switch over to a backup or redundant system in the event of a network outage or technical snag is called as WAN failover. This technology effectuates a redundant WAN, which is the backbone of business continuity. In simple terms, WAN Failover is the switch over from a primary system to a backup system upon the failure of an active system. A WAN backup unit considerably reduces operational risk. WAN Backups minimize revenue loss, employee productivity loss, and critical infrastructure loss due to network outages. Due to large amounts of data transfer, information sharing, and other web-based applications, there are large quantities of network traffic. This constantly results in network congestion and necessitates a redundant WAN to overcome the weak spot. WAN failover has the capacity to make the network resilient to breakdown. When there is a failure of any of the active WAN lines, it is possible to switch over to the other WAN lines with the aid of failover WAN. A redundant WAN will allow for fault tolerance in the network architecture, which enables the system to avoid data loss and downtime and continuing the functions even when failure occurs. Technology has grown over the years offering devices and solutions such as firewalls, routers, etc. to provide support to WANs. Large enterprises always use multiple WAN connections so that WAN Backup is available at all times. With failover WAN, there is no downtime in systems and the process flow is smooth. Innovators of technology such as FatPipe Networks provide advanced solutions for redundant WANs. FatPipe devices allow multiple and varied connections to ISPs. They take disparate connections (DSL, T1, ISDN, T3, Cable Modem, Wireless, ATM and EU standards such as E1 and E3 etc.) and dynamically load balance across the lines. This is an essential feature for WAN backups. The Internet has become the indispensable mode for communications and commerce. Both large and small enterprises depend on WANs to conduct their businesses. These companies require systems that support a strong and secure WAN infrastructure, with WAN failover options. A redundant WAN will facilitate “high availability” and provide continuous Internet connectivity. Failover WAN or Redundant WAN considerably maximizes WAN application performance across the Wide Area Networks. High data throughput, which is effected by WAN Backup methods, enables the avoidance of delays in data transmission. This eventually yields higher productivity in businesses. FatPipe Networks, a technology leader, has developed unique solutions, which provide high levels of redundancy and availability for the WAN infrastructure and also enable maximum bandwidth utilization. FatPipe products achieve aggregated speed, redundancy, and failover by bonding any combination of T3, T1, DSL, Cable, ISDN, or Wireless connections. FatPipe’s patented WARP technology intelligently senses the active link when failures occur and will automatically failover the active traffic. FatPipe products have an array of advanced product features including automatic line failover, dynamic load balancing of IP traffic, site-to-site and unit failover capabilities, which substantially increase the efficiency of WANs. WAN Backups driven by FatPipe products positively impact business continuity of companies since it ensures the highest levels of redundancy, reliability, speed, fault tolerance for mission-critical applications.
