You can hear the difference
VoIP (Voice over Internet Protocol) has revolutionized the way phone calls are made. VoIP saves businesses and consumers money over traditional calling plans while specialty services such as Skype offer voice and video at no charge.
VoIP quality is often limited by the quality and quantity of bandwidth. New codecs (algorithms that convert sounds to packets and back again) deliver excellent audio. But VoIP data packets need to flow smoothly over the link otherwise packets arrive out of order or not at all. Competing demands for Internet bandwidth (simultaneous use of VoIP, email, surfing, file transfer, etc.) can create congestion which leads to dropped packets. When packets get dropped, calls get choppy.
Managing Quality of Service
Quality of Service (QoS) in a router or modem allows the device to prioritize traffic. QoS allots bandwidth to time sensitive content such as voice and video ahead of email or web surfing. But QoS on a complex network requires time consuming customization and assumes a constant Internet connection. Speeds on many Internet services (particularly satellite, 3G, 4G and LTE), fluctuate as demand goes up and down. As a result, QoS may not properly manage bandwidth resulting in poor quality VoIP experience.
Enter Adaptive Queue Management
Acceleration Systems has the first commercial release of Adaptive Queue Management (AQM) technology. AQM monitors the speed of the Internet connection and adjusts the rate at which applications on the LAN send data to the gateway router. Controlling the rate that data arrives at the gateway avoids the backup of packets – what is referred to as buffer bloat. When the buffer fills, packets can time out or not be detected by the queue manager on a timely basis.
Since the queue manager cannot prioritize packets it does not see, balancing the flow of data from applications to match the immediate (and changing) capacity of the Internet connection insures time sensitive packets, such as voice and video, get the bandwidth they need without being delayed. Adaptive Queue Management is especially helpful on extreme links like satellite where the speed of the outbound connection changes widely and often. It is also very helpful on other contested links including wireless technologies and busy cable/fiber connections.
As good as it is, you need more than Adaptive Queue Management to maximize throughput over your Internet connection. Acceleration Systems cloud-based bandwidth optimization includes a full suite of optimization procedures that increase the data capacity as much as 250%. That extra capacity insure there is always sufficient bandwidth for calls. Find out for yourself with a free 14 day on-site trial.
