The technological arm of the world has been extended to every nook and corner of the globe through the widespread use of the Internet. Businesses, corporate sectors, educational institutions, and homes are all engulfed by the Web. In such a scenario, certain key factors involved in the functioning and application of Wide Area Networks (WANs) are worth highlighting. Routers are those network devices that handle the task of routing messages between two or more networks. ADSL (Asymmetric Digital Subscriber Line) Router is a type of router, which is used to connect one or more computers to a data line in order to make use of ADSL services. It is an effective mode of data transmission, and is fast. An ADSL Router also called ADSL modem or DSL modem, connects a computer or router to a DSL phone line and avails an ADSL service. A feature of ADSL is that the download speed is greater than the upload speed. Some ADSL Routers have the capability to connect and also share the ADSL service with a group of computers on a network. An ADSL router would have the following hardware components: transformer, data connection (Ethernet or USB), digital data pump, line driver, filter, and micro controller. It also has a functional block called ADSL Terminal Unit-Remote (ATU-R or transceiver), which performs functions such as demodulation, modulation, and framing. Specific functions like IP routing and bridging are done by other functional blocks. A combination of high-speed ADSL technology and a robust router would yield superior connectivity. However, the speed of an ADSL Router is determined by the ISP one has. ADSL modems permit higher data rates than regular modems since they use a different modulation technology. Wireless ADSL Router has a wireless access point for connecting to the network, which further enhances the functionality and flexibility of these devices. An ADSL Router does not require an IP address, but it is assigned one for the sake of management. It can be configured manually through opening a Web page in the browser. These provisions make this device more suited to businesses. The key business imperative that ensures the business continuity for companies is robust WAN connectivity. Ultimately, what matters most is providing uninterrupted services amid probable service outages. Companies that are totally dependent on their online service find ADSL Routers beneficial. Since the ADSL technology offers higher speed in the “download” direction, end users can avail information quickly. In a nutshell, these devices (ADSL Routers) integrate an ADSL modem for Internet connection, Ethernet switch connectivity to LAN devices, and a router functionality to interlock the two networks. As apparent from the set up, the ADSL Router routes messages efficiently and provides fairly good uninterrupted connectivity. FatPipe Networks, a technology solutions provider, is the inventor of router clustering technology, which provides highly redundant, reliable and high-speed Internet access for mission-critical applications. Over the years, it has gained wide acceptance from industries due to the superior technology and reliability. The robustness of WANs determines the business continuity in companies and hence FatPipe solution is sought exclusively to ensure the same. FatPipe can cluster the routers of multiple datalines irrespective of the quality or the speed of the DSL lines. It ensures that the data flow is smooth and uninterrupted in the event of failures. FatPipe makes use of DSL technology and brings in efficiency with its many options for load balancing datalines. It positions itself on the forefront of the technological revolution and benefits end users with its wide array of technological products.
