WAN Load Balancing
The cyber era has seen a paradigm shift of businesses from a conventional to a model that has Web dependency to various extents. The Internet is used for a major part of business operations and companies require stable Wide Area Network (WAN) connections to ensure business continuity, which is the lynchpin of business growth. Increased bandwidth and continuous “uptime” in spite of outages are major requisites. Load balancing is the process of evenly distributing data across a computer network to maximize network efficiency. Load Balancing provides optimal resource utilization, high throughput and availability, and minimal latency in networks. The load balancing function is executed through a dedicated program or hardware device. Load balancing strives to ensure that data flows evenly across networks. Some of the common load balanced systems are File Transfer Protocol (FTP) sites that have high bandwidth, Network News Transfer Protocol (NNTP) servers, Domain Name System (DNS) servers, popular Websites, and Internet Relay Chat (IRC) networks. Load balancing is also utilized in redundant communications linkage and implementing failover.
