WAN Redundancy
The network-linked community is reliant on the global information database and the Internet, to meet its growing demands in each hemisphere of life. Wide Area Networks (WAN), the most popular network, extends to a broad area and makes use of common communication links (telephone lines, wireless, microwave links, and satellite channels) to transmit data. A robust WAN considerably increases application performance and ensures business continuity. WAN Redundancy is a critical construct that is a pivot than ensures business continuity and general overall performance of networks.
The paradigm shift in recent times is characterized by the letter ‘e’ preceding most of the normal business activities, for instance, e-commerce, e-mail, e-governance, among others. While hard copy will be around for a long time, its importance has diminished with the advent of networks and their linkages. There are infinite technological improvements in all fields, and a virtually created new world of opportunities. While the world is becoming ‘electronic’ it is essential that businesses are equipped with the right technology solutions and gadgets to survive in the highly competitive global business era. A WAN is the global network for information transaction and WAN Redundancy is an indispensable constituent.
Network traffic is rapidly increasing due to the amount of data transfer, information sharing, and other web-based applications. This invariably results in network congestion and the performance of single WAN connections add to the list of potential weak spots in global network architecture. Large enterprises need WAN redundancy and multiple WAN connections to keep their business processes going forward without interruption. Redundancy may be defined as the secondary backup system, which takes over seamlessly in the event of any of the WAN failing connections or system outages and executes similar functions as the primary system. WAN Redundancy is primarily a back up system over a network setting, which enables continuous ‘uptime’ and undisrupted flow of business operations.
A WAN is capable of extensive scalability, which makes it distinct from a Local Area Network (LAN). A Redundant Wide Area Network can reach the intended destination with relative ease and with no disruptions, be it network outage or system failure. While WAN Redundancy is the core, there are enhanced technology solutions available in today’s market place that offer high levels of reliability, security, and bandwidth management coupled with ease of deployment. FatPipe Networks is a pioneer in providing WAN optimization solutions, catering to the technology requirements of a broad clientele.
WAN optimization techniques can enhance the performance of WANs and offset latency and other technical issues. High data throughput and WAN Redundancy are crucial factors that determine business continuity in organizations. Delays in transmission of data result in low throughput, which in turn can have a profound impact on productivity and profitability. Redundancy in WANs helps businesses to avert disruptions in network services. With WAN Redundancy in place, when there is a network outage, the system immediately switches over to the active WAN link and load balances if more WAN connections are present.
WAN Redundancy is integral for enterprises to run mission critical applications over the Internet. The ubiquitous usage of the Internet demands that the systems constitute a robust and secure WAN infrastructure, which is capable of high availability. It is essential for large enterprises to give due importance to WAN Redundancy while planning business strategies. One of the salient features of WAN Redundancy is that there is ‘uninterrupted service’ or ‘constant uptime.’
FatPipe Networks, as a technology solutions leader is the inventor and patent holder of router clustering technology. FatPipe devices allow multiple and varied connections to ISPs. They take disparate connections (DSL, T1, ISDN, T3, Cable Modem, Wireless, ATM etc.) and dynamically load balance across the lines. FatPipe technology also facilitates failing over of network traffic to available lines if any of the connections fail. The WAN infrastructure is strengthened and FatPipe provides the highest level of reliability and redundancy for inbound and outbound IP traffic. WAN efficiency is thus increased and businesses improve productivity.
