Wide area network (WAN) is a form of computer networking that enables transmission of data and information over a wide range. It can either link local area networks (LAN), MANS or any other small range computer networking protocol. Both private and public ventures have well embraced the WAN communication connectivity since its inception in the early 90’s due to its amazing cost-saving capabilities. Three types of WAN connectivity are well understood and used worldwide to offer useful communication modes. With proper configuration and connectivity, WAN promises a seamless communication avenue that overtakes the challenges associated with other computer networking protocols.
WAN link connects computers and devices belonging to an organization over cities, countries or even globally. Virtual protected network (VPN) is vital in connecting computers in the WAN systems since it provides a substantial sense of security to users. Lately, WAN links have exhibited more reasonable protection thus the incorporation of fiber optics cables as they guarantee enhanced security and better performance. It is a very costly undertaking, and WAN communication must be maintained efficient and optimal in performance. Network redundancy is critical to maintaining a WAN network productivity and reliability to users; it ensures network availability in case of system failure thus surety of timeless connection. Therefore, it provides a leeway out of network failover.
WAN Link Failover
Network disruption is a common phenomenon in many organizations and has led to enormous losses. Some of these losses could be avoided with proper preparation and mounting preventive mechanisms. The extensive nature of connectivity in WAN further predisposes to frequent downtimes and network failures, and a defensive arrangement is thus not negotiable to organizations wishing to keep their services up and running even amidst disruptions. WAN Failover comes in handy as it is an essential preventive method for keeping disruptions at bay. It helps explicitly to minimize interferences and interruptions by monitoring WAN, identification of any improper configurations and outages, rerouting traffic as required and generally optimizing communication within the network.
WAN link failover is especially vital in curbing user frustrations, loss of production and delays in production commonly witnessed in lacking communication networks. It does this by transferring traffic from a compromised connection to a redundant network component thus communication is always maintained at topnotch. Meanwhile, diagnostic procedures are run, and degraded systems get restored. WAN link failover is therefore critical in ensuring availability and reliability of network which is essential in maintaining communication as well as production.
Competition among businesses get fierce daily, and it is essential that every enterprise maintain maximal productive uptime. Reliable network and communication is an integral component of ensuring access to services and products in organizations thus it is now even more paramount that every business venture should have a robust network system. Technologies and strategies to keep network performance and communication optimal continue to be invented and implemented in computer networking to help realize a five nines uptime. WAN redundancy is one such initiative that has soon remarkably excellent result in maintaining connectivity.
Redundancy involves system design duplication to ensure viable options in case of system failures. Components of the system that can be duplicated include data, hard disk drives, switches, operating systems and many more. Such are called redundant network system components and in most instances are very important in the smooth operation of a business or an organization. In layman’s language, redundancy provides a source of back up; thus we can have different forms of redundancy ranging from data redundancy, server redundancy and network redundancy where WAN redundancy is conspicuous.
WAN redundancy is majorly a network backup system that ensures minimal service interruptions. In case of downtimes or network outage, WAN redundancy will switch to the more active network and maintain nearly constant uptime. During this switch, troubleshooting is done, and operators get notified of the interruptions and corrective measures mounted to rectify the possible problem. Redundancy, therefore, help systems avoid disruptions in network services. The level of redundancy you incorporate in your network will depend on how large your company is and the diversity you wish for in your system. Some of the requirements in incorporating WAN redundancy include a router and a WAN provider for backup bandwidth.
Switching between connections in case of system failure require a meekly designed versatile backup link referred to as a redundant link. So what is a redundant link? A redundant link is a connection that provides different avenues of executing a given task. It offers different viable options through which a given function can be performed in the event of failure of one route. Redundant links in a system are achieved by integration of multiple switches or multiple links between the main switches. Redundancy of a connection in an enterprise is satisfied if its presence or absence does not alter the natural operation mechanism of the system. A striking proof redundant link in networking is that it enhances the reliability of the connection. However, on the other side of the coin, redundancy limits advancement as it is challenging to include complex and sophisticated devices or technologies in such systems.
Proper Configuration Facilitate Optimal Network Functionality
To fully exploit redundancy, system simplification and less complicated arrangement are inevitable. The redundant NIC function will initialize a failover when a cable fault or a hard error occurs on the adapter. A failover triggers the driver to switch traffic from the active adapter to the backup adapter. The dynamic and backup roles get alternated between the adapters of the redundant pair. How well redundancy works in WAN networking depends mostly on the proper alignment of components; switches, routers, and servers as well as coordination.
Redundancy in networking is proving essential to companies and should be quickly embraced. Importance of redundancy especially in WAN link coupled with the vast benefits it offers should entice you into accessing it and trying it out. However, financial considerations should remain a priority, and hence you should only incorporate it if the pros outweigh the cons for your particular entity.
