WAN redundancy - How does it impact VoIP?

Achieving WAN redundancy to improve VoIP Adding WAN redundancy to your organization’s network is becoming a fundamental component for today’s demanding applications. But WAN redundancy is probably most important for VoIP or any other real-time applications because of the business-critical nature of those IP apps.

Recently I wrote a contributed article titled “Achieving Quality VoIP from the Cloud” for the publication Business Communications Strategies. Here is a brief excerpt that examines the WAN redundancy approach for VoIP:

“…Fortunately, there are new and emerging technologies that can optimize performance without the need for costly upgrades to premium Internet services. These technologies also protect VoIP services from jitter, latency caused by slow network links, and other common unpredictable behaviors of IP networks that impact VoIP performance. For example, Broadband Bonding, a technique that bonds various Internet lines into a single connection via WAN redundancy, boosts connectivity speeds and improves management of the latency within an IP tunnel. Advanced algorithms can closely monitor WAN links and are able to make intelligent decisions about each packet of traffic, ensuring nothing is ever late or lost during communications…

…Broadband Bonding and SD-WAN is a recent technique that melds various numbers of Internet lines into a single connection adding WAN redundancy. Using this technique provides faster connectivity via the sum of all the line speeds, as well as intelligent management of the latency within the tunnel.  The solution is cost-effective, even for global firms that have hundreds of branch offices scattered around the world, because it can be used with existing infrastructures, enabling disparate offices to have the same level of connectivity as the headquarters without the outlay of too much capital. The end result is a faster connection with multiple built-in redundancies that can automatically shield negative network events and outages from applications such as VoIP. Broadband Bonding also combines the best attributes of the various connections, boosting speeds and reliability.

Additionally, new “armor” technology has been developed to shield VoIP services from the negative effects of IP jitter, latency, packet drops, link disconnects and other issues. This technology relies on Network Calculus, a unique research field of study in electrical engineering that is able to model and optimize communication resources. Through decision algorithms, it monitors traffic and refines routing in the aggregated, bonded pipe by enforcing application-specific goals, whether it’s throughput or reduced latency…”
