Discover services in network using UDP multicasts:

• Server sends UDP multicast periodically (once per 4 seconds or so).
• Clients listens for these - server’s address is IP from which the multicast was received.

Multicast content:

• Port number of the listening TCP/TLS socket and transport.
• IO network names which reply to multicast (first network name to be used, if client doesn’t know it’s network name).
• Time stamp
• Random number
