A Dante system is running on a converged enterprise network. Clocking and discovery are working OK, but audio only passes in unicast. You conclude that a firewall is blocking your multicast audio packets. What port would you ask the IT administrator to unblock?

The correct answer is UDP 4321.

Explanation:

TCP port 4321 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP / IP networks. TCP is a connection-oriented protocol, you need the handshake to determine communications from beginning to end. Only when the connection is determined, the user data can be sent bidirectionally by the connection.

Attention! TCP port 4321 guarantees the delivery of data packets in the same order, in which they were sent. The communication guaranteed by TCP port 4321 is the major difference between TCP and UDP. The UDP port would not guarantee communication as TCP.

UDP port 4321 provides an unreliable service and datagrams can arrive in duplicate, broken down or lost without notice. UDP port 4321 thinks, that the verification and correction of errors is not necessary or fulfilled in the application to avoid the overhead for processing at the network interface level.
