Enterprise: Voice over IP (VoIP)

Toll Grade VoIP over any WAN

VoIP is a real-time application based on UDP that is highly sensitive to WAN traffic quality – jitter, latency and packet loss. As a result, it is not enough to simply reduce the bandwidth usage of other applications in order to make room for VoIP traffic over the WAN. Rather, it is a requirement to maintain LAN-like network characteristics over what will be an over-subscribed or congested WAN, without inducing added latency.

Silver Peak employs a variety of tools to ensure toll grade VoIP performance over the WAN.  This includes advanced Quality of Service (QoS) and loss mitigation techniques to ensure proper traffic handling of real-time voice traffic - even during periods of heavy congestion. In addition, Silver Peak's data reduction techniques work on all IP traffic, including UDP applications, to maximize available bandwidth when compression and deduplication are possible.
