NTP (Network Time Protocol) implements IETF RFC-5905 (Network Time Protocol Version 4: Protocol and Algorithms Specification).

There are two--brief--parts to this Inline Activity:

First, gain an overall understanding of the basic operations of NTP; then, In the space below: Write a BRIEF description of the similarities and differences in the way(s) NTP uses broadcast vs. Multicast protocols.

Second, gain a specific understanding of NTP-Multicast's use of the TTL parameter. [IMPORTANT: Be sure you understand what is the default setting for TTL.] Then, in the space below (regardless of whether you believe it is feasible, or not), describe what would happen if a node listening for NTP messages consumed three versions of the same message: Version 1, from the first "hop" (TTL = TTL_DEFAULT - 1). Version 2 from the middle "hop" (TTL_DEFAULT/2). Version 3, from the final "hop" (TTL_DEFAULT - TTL_DEFAULT).
