How often have you been on a VoIP call only to experience dropouts or garbled sound? Or endured a video conference with pixelated images or even a frozen screen? The expanding use of Unified Communications (UC) applications has placed increased pressure on IT to deliver an exceptional user experience to employees. But when user experience deteriorates enough, it results in a flood of calls to the IT help desk. Delivering consistent, high quality real-time communications is difficult, if not impossible, with a traditional router-centric wide area network architecture.
Why? Because conventional routers can’t overcome inevitable packet loss that negatively impacts quality voice and video communication quality and the user’s experience and productivity. WAN architectures based on traditional routers typically backhaul all traffic to a headquarters-based data center, adding latency or delay that contribute to poor quality.
