2. Assignment #5 Peer discovery using multicasting
refer to the on the class list for a primer on multicasting
consider getting a multicasting demo working before integrating into your peer
Multicasting parameters
address =
port = 1966
TTL = 2

3. Peer Discovery
Upon startup, peers will send a register verb to the multicasting address
they will also continually listen on this address
the multicasting address is for sending/receiving register verbs only; all other communication is done on the “regular” TCP address/port.
The GUI must allow for a “resend register now” capability as well as defining a timer (in seconds) to periodically resend a register verb
use 180 seconds as a default
