The most common place where I have encountered that would involve differing AUPs on different links.
For example, if one has a link which is built on an amateur radio layer 1, one cannot carry commercial, pornographic, encrypted, or certain other kinds of traffic on that link. I believe Internet2 vs. public transit may also pose some such requirements. Other situations I’ve seen involve data privacy concerns and/or security zone issues. Common? Not in my experience. Usually done with a combination of ACLs, Routing Policy, etc. Owen > On May 6, 2015, at 3:56 PM, Randy Bush <ra...@psg.com> wrote: > > a fellow researcher wants > >> to make the case that in some scenarios it is very important for a >> network operator to be able to specify that traffic should *not* >> traverse a certain switch/link/group of switches/group of links >> (that's true right?).
