The professor is technically right - it is not a function of routing. The fact that many implementations draw on associated technology doesn't stop the device being a router, but it does not mean Bandwidth Management is a defining function of the router - it is a nice to have ancillary function.
OSPF, BGP, RIP, and so on most definitely are implementations of routing functions - they assist in the passing of packets from one network to another. DNS cache, bandwidth management, and bridging do not maintain routing tables, alert neighbours, or deliver packets between networks. What they do is enhance the networking experience by adding features which are best implemented at the point of routing. The strength of a particular implementation, and LEAF is a perfect example, should be viewed as the richness of these ancillary functions. What they do is increase the breadth of the product, taking it beyond a paper routing tool into a valuable asset. Because it adds to the functions of a paper router rather than altering them, LEAF remains a router. Had LEAF altered the basic functions of routing, say by operating only at layer 2, then LEAF would cease being a router. It hasn't. In this respect LEAF is the richest routing environment available because it adds more and better ancillary functions than anything else, while maintaining near perfect base routing functions. The same could be said of Operating Systems, the Gnu tool sets are not part of the Unix/Linux operating system per sae, but it would be a miserable world without them. Rather an academic distinction but then this was a university lecture.
