Network troubleshooting: Network traffic
Two main types of communication occurs in the CARESCAPE Network:
Broadcast and Unicast.
Broadcast traffic is sent from one device to all devices on the

network. Examples of CARESCAPE broadcast traffic are device
discovery, alarms, and time synchronization.
Unicast traffic is sent from one device to another specific device on

the network. An example of CARESCAPE unicast traffic is patient
waveforms.
Upstream broadcast: The Dash patient monitor sends broadcasts to

other network devices.
Downstream broadcast: The Dash patient monitor receives

broadcasts from other network devices.
Most of the Dash network problems are broadcast related. If broadcast is
not working, it is unlikely that unicast communication can work.
