The most valuable feature would be the ability to deep-dive into the network stack, reasonably quickly, reasonably effectively, and generate useful transaction data for troubleshooting and analysis.
For example, if you have a transmission between yourself and a customer, oftentimes there might be latency, there might be whatever the connectivity issue is. There are millions of different things that could happen. Using NetMaster it's easy to dig into the TCP/IP stack and generate useful data to troubleshoot where the problem is. That allows you to fix the solution based on targeted troubleshooting because there's so much data there, versus just pointing fingers and saying "Hey it's your problem," "No it's your problem."
