Joe, To close the loop and make the document forward, we simply say the following: Infrastructure multicast is a capability needed by networking services, such as Address Resolution Protocol (ARP), Neighbor Discovery (ND). All we need is to differentiate multicast messages originated from users/applications from the infrastructure multicast at the introduction section. Not intended to describe in detail of the Infrastructure multicast.

It might be useful to describe them all as "services", though. I.e., to replate "network protocols" with "services" (or maybe even "networking services" - to distinguish them from OS services, but not give the impression they belong at the "network" layer).

Application-specific multicast traffic are originated and consumed by user applications.

Even if you do not consider them relevant for this framework, perhaps you should briefly mention them? [Linda] I don’t think we can enumerate all network protocols (many of them use multicast). The purpose is to differentiate multicast originated by network nodes and the multicast originated by applications. DHCP and mDNS are applications ("L7"). Network nodes don't originate anything; their protocol layers do (link, network, transport, application). It might be useful to focus on the difference being "network infrastructure" vs "user applications" as the better way to describe the difference. I don't think "network nodes vs. applications" is clear or meaningful. Joe
