I worked for Cisco, and I agree. I was in what the local government had been told was a special research unit in order to get a billion dollar tax break, fixing decade old bugs in some stupid built-in ping tester that old customers liked. Cisco's innovation was weighted down by the solid gold boat anchor known as classic IOS. The biggest innovation I saw in my team was to carve out a piece of the 90's style C code from the embedded (i.e. untestable) system as a library and test it on Linux with C++ and valgrind.
