Voice over Wireless LANAerohive Solutions by Use Case
Successfully deploying an application like voice over wireless LAN requires the underlying infrastructure to be highly available, and have low latency and sophisticated quality-of-service (QoS) capabilities. Aerohive's unique stateful high availability, mesh redundancy, and stateful failover ensure that the network is always up. The best path forwarding ensures the data path is continuously optimized to provide the lowest latency, and the lack of a controller means there is no added latency or jitter due to backhauling the wireless traffic.
While standards-based IEEE 802.11e/ WMM (Wireless Multi-Media) extensions are also implemented – WMM alone isn't enough. To manage the flow of traffic into the WMM queues, Aerohive implements sophisticated QoS, with eight queues per client station right at the network edge where they can immediately respond to the dynamically changing RF link, rather than at a centralized controller multiple hops away from the radio.
Aerohive Networks cooperative control architecture's unique stateful high availability, mesh redundancy, path resiliency and proactive session synchronization ensure that the network is always up. The architecture's best path forwarding ensures the data path is optimized to provide the lowest latency and the lack of a controller means there is no added latency or jitter due to backhauling the wireless traffic. Sophisticated QoS, with eight queues per client station in addition to the standards-based IEEE 802.11e/WMM (Wireless Multi-Media) extensions, is enabled at the network edge, in the Aerohive AP, where it is able to instantaneously respond to changes in the wireless signal. This is a far superior approach for supporting mission-critical applications, such as VoWLAN, than relying on a centrally located controller to do policy enforcement or queuing after the traffic has already traversed the network or too far from the AP radio to respond to RF throughput fluctuations.
Together with a robust set of voice classification, resiliency, quality and power saving features Aerohive's cost effective architecture and wireless mesh cababilities allows the enterprise to provide whole enterprise wireless LAN coverage, even in hard to wire and RF challenged locations. This combination of wireless LAN network availability, coverage and performance allows Aerohive Networks to deliver the underlying infrastructure able to support VoWLAN with the high levels of voice quality and availability expected by the enterprise.
