Link Load Balancing for Optimizing Internet Bandwidth
Internet connectivity today, is the fundamental part of every business operation, and a critical component that needs to be highly reliable and always available. Link load balancing helps maintain redundant, easily managed links to meet business needs, ensuring consistent availability without having to rely solely on Internet service providers. It provides an efficient, cost-effective, and easy-to-use solution to capitalize on utilization and availability of Internet access while curtailing cost.
Most enterprises lease two ISP links connecting the internal network to the Internet to increase the reliability of internet access. While the primary link is being utilized, the other link acts as a back-up. By providing backup capacity for use during ISP link failures this solution enhances reliability. Link load balancing offers a powerful solution with quick return on investment, for enterprise customers that want to avoid the challenges of BGP routing without the wastefulness of idle backup ISP link. BGP or Border Getaway Protocol is complicated to manage and necessitates distinctive knowledge and active cooperation of the ISPs. It does not offer an efficient solution despite the complexities and challenges.
How to optimize Internet Bandwidth with link load balancers
Advanced link load balancers use end-to-end proximity measures and service response time to determine the best link to service any given application transaction. The other elements include the following.
* In bound and out bound traffic is balanced efficiently with link load balancing. It uses all the accessible ISP links with intelligent traffic management.
* Based on vital performance metrics, links are selecting using load balancing methods. Metrics that have a direct positive impact on the business like bandwidth limit, link weight, bandwidth cost and ISP pricing model, etc. are a criterion point.
* To ensure reliability, enterprise customers do not have to rely on low-risk, high-cost ISP services. By aggregating bandwidth of several links from various ISPs, there is a cost reduction and an overall improvement in reliability and accessibility.
* Failure risk associated with any one link is eliminated as all the links are used at the same time. With the losing of a link there is only a reduction in the obtainable bandwidth not in the access availability and performance.
* Monitoring the performance and well being of ISP links are done by the intelligent checks used by link load balancers. They energetically switch traffic to healthier and better performing links. Link load balancers are usually positioned at the intersection of the internal and external network to provide security, as network and application security is a critical enterprise need. It is essential to make certain that link load balancers do not become single points of failure, as enterprises deploy link load balancers to eliminate performance bottlenecks and inadequate links from their Internet access infrastructure. Link balancing is the perfect technology for today’s organizations and is effective with almost any network.
