Can anyone recommend a textbook or online resource for learning the current state of multicast technology, from the perspective of a network engineer/designer?
The 'bible' that most of my more experienced colleagues seem to use is Developing IP Multicast Networks, by Williamson, which was published in 1999. Has multicast technology really not moved on since then? Or are the same principles and protocols still in use, without only incremental changes not warranting a newer text?
