The Network panel shows the logins, connections and movement of data on the Unix system:

Logins

The number of users currently logged on to the machine.

Connections

The number of external programs with which the machine is currently communicating. The types of connections shown are:

Established	The total number of TCP/IP connections to this machine in the ESTABLISHED state.
TIME_WAIT	The total number of TCP/IP connections to this machine in the TIME_WAIT state, where the local socket has closed, and it is waiting for the remote end to signal that it has done the same.
CLOSE_WAIT	The total number of TCP/IP connections to this machine in the CLOSE_WAIT state, where the remote end of the connection has shut down, and it is waiting for the local end to do the same.

NIC Bandwidth

The rate at which data is moving through the NICs (network interface cards).

Packets	The rate of network packets being received and sent for the network card on this host that has the highest rate of packet transfers.
Errors	The rate of erroneous network packets being received and sent for the network card that has the highest rate of packet transfers.
Packets	If more than one network card is installed on this host, this is the rate of network packets being received and sent for the network card that has the second-highest rate of packet transfers.
Errors	If more than one network card is installed on this host, this is the rate of erroneous network packets being received and sent for the network card that has the second-highest rate of packet transfers.

Data flows between the Network panel and CPU panel

Network (Network to CPU)	Rate of incoming network data The incoming rate of data to the server. Note: Spotlight contributes to the data traffic as part of its diagnostic activities.
Network (CPU to Network)	Rate of outgoing network data The outgoing rate of data from the server. Note: Spotlight contributes to the data traffic as part of its diagnostic activities.
Network Errors (Network to CPU)	Rate of incoming network errors The rate at which errors are received from the network.
Network Errors (CPU to Network)	Rate of outgoing network errors The rate at which errors are sent from the machine to the network.
