Quality of Service for VoIP Networks

Quality of Service for VoIP Networks

NetVanta routers and switches offer Quality of Service (QoS) for prioritizing delay-sensitive, mission-critical traffic, such as Voice over IP (VoIP). These routers prioritize traffic using Low Latency, Weighted Fair, or Class-based Weighted Fair queuing. NetVanta platforms with an integrated switch also support 802.1p Class of Service (CoS) standards, using Weighted Round Robin and Strict Priority queuing. In addition, to help monitor and troubleshoot VoIP issues, the NetVanta routers support Voice Quality Monitoring (VQM), which is a graphically-intuitive interface to track Mean Opinion Score (MOS), jitter, delay, and packet loss statistics.
