Link load balancing is simply the method of providing a single internet connection from multiple providers. For organizations that require maximum performance, high bandwidth for a large number of file transfers and busy networks that must consistently maintain high reliability, this type of solution is quite effective. Link load balancing is usually quite straightforward to implement for almost any type of organization. Since link load balancing helps manage several backend servers redundancy, reliability and productivity usually is increased.
One of the major reasons networks and organizations choose to implement link load balancing is due to increased reliability. The failure of a network even for a few hours can cost an organization dearly in productivity and business. With link load balancing, you can achieve extremely high uptime reliability (99.999%) and if a problem does occur and one of your providers does fail, switching from one provider to another is automated and instant. Not only do your customers remain able to conduct business or use your network resources, but even in the event of a WAN link outage, link load balancing can reroute your network traffic to ensure 24x7 uptime for all parties that relies on your network and servers.
There are many reasons why an organization can reduce costs with link load balancing, however, the biggest advantage is that link load balancing works with any type of broadband connection, whether T1, DS3, Cable, ISDN, Frame, DSL, etc. The only thing necessary is a simple Ethernet handoff which establishes your WAN link. By being able to utilize various forms of inexpensive broadband connections, you can keep non critical applications (e.g. email, internet web surfing) on less expensive broadband connections and more critical application on your more reliable connections.
Your organization can benefit from increased performance using link load balancing. In most cases your network can balance your incoming requests across your multiple WAN links. This is usually done with an Active DNS module, easily serving traffic between your broadband connections based on the best path available along with network metrics.
It’s easy to manage your networking information routing with link load balancing. Many link load balancing solutions come with software that offers advanced routing capabilities. An organization can easily determine its critical and non critical applications and route them efficiently. With link load balancing, splitting up your organizations network traffic by importance or application (e.g. VPN, VOIP, etc) is quite easy to achieve.
Link load balancing can be implemented and is effective with almost any network. With an increase in reliability, a reduction in costs and added performance and management, link load balancing is the perfect technology for today’s organizations.
