UC Implementation Readiness – Step 1: Evaluate Existing Network Equipment FactorsConsiderations ThroughputThe required bandwidth depends on your estimated number of simultaneous calls and your system configurations. Network Latency Latency is the time it takes for a sound to reach the listener. It can be impacted by network equipment, slow links, congestion, and other factors. No more than 100ms is the target. Packet Jitter Jitter is the difference in latency between voice packets or the difference in the time between the arrival of packets. Jitter should be minimized by engineering the capacity and QOS mechanisms. Packet Loss Packet Loss is the networks reliability measure. When voice packets are lost, there are gaps in conversation. Networks need less than 1% packet loss. Maintain autonomy between network equipment and unified communications applications decisions
