Over the past couple of decades, the Computer networking industry has seen many trends come and go. Looking at how things stand today, the core skill sets of Routing and Switching look likely to become dated as the number of experts proliferate the market and the task of routing the packets through the Internet has become a commodity for so many deployments. Fundamentally, the core job of routing remains the same, from the perspective of a device. For it, a packet (or data) comes in and it needs to make a decision on where to send it out to. The USP for any device resides in the speed with which it can make this decision and the speed with which the packet can be forwarded out another interface, towards its ultimate destination. As with so many other technology industries that reaped the benefits of Moore's law, it was the same with the High Performance Networking industry. Shrinking space for the transistors used for switching meant that so many more operations could be performed...
