In an object-oriented program, the largest switch/case statement I've ever seen has more than 20 conditions. During the run, the code module executes all the conditions each time. Each condition is responsible for creating a new object that is used to communicate with the external use of the application API. After performing some general troubleshooting on one of them, I began to look at the interfaces implemented by the application. To my surprise, e

I believe many people are familiar with tracing network faults with traceroute ip addresses. This is based on the IP address (Layer 3) route tracking, and is suspected to be used to eliminate most network faults. The layer-2 route tracing is very similar to the layer-3 route tracing. One essential difference is that Layer 2 routing tracking is based on MAC addresses and solves Layer 2 connection faults. In determining the data transmission path in the second-layer topology, this second-layer rou
