The WOC market is rapidly maturing, but it is still dynamic with a high level of vendor innovation. This has led to different vendors offering different combinations of features. So, before choosing a vendor, ensure you understand the applications and services running on your network, and the protocols they use. Also conduct a detailed analysis of your network traffic to identify specific problems — for example, excessive latency, bandwidth oversubscription or lack of prioritization for certain types of traffic. Finally, insist on a real-life trial before committing to any purchase.
