Smart Technologies Smart Bridgit 4.5 - Manual (Page 71)

Verifying communication protocol
SMART Bridgit software uses three types of network protocols:
l
TCP for data and video
l
UDP for VoIP audio
l
HTTP if a client is unable to connect to the server using TCP
Communications using TCP and UDP have lower network delays than those using HTTP protocol,
and using them helps to prevent latency issues.
Use SMART Bridgit software’s troubleshooting tool to determine the network protocol you’re using.
See Using the SMART Bridgit troubleshooting tool on page 58.
Ensure that values appear in the TCP Port and UDP Port fields. If these fields have N/A in them, or if
the Proxy Connection option is selected, contact your administrator to open the TCP and UDP ports
to connect to SMART Bridgit server. See Administering the server software on page 37. See
SMART Bridgit and firewalls on page 11 for information about configuring firewalls and proxy servers.
Checking for firewalls
g To determine if the client is behind a firewall
1. On the client computer, open the SMART Bridgit troubleshooting tool. See Using the
SMART Bridgit troubleshooting tool on page 58.
The Connection area displays the ports and protocols the client computer is using to
communicate with the server. If a client is communicating through a proxy server or if the
client’s UDP and secondary TCP ports are blocked by a firewall, the Proxy Connection check
box is selected.
2. Contact your administrator to open the TCP and UDP ports to connect to SMART Bridgit
server
Measuring latency and packet loss
Packet loss occurs when one or more packets of data traveling across a computer network fail to
reach their destination. Packet loss rates depend on factors including bandwidth, communication
path reliability and router buffer size. When packets are lost, latency increases as the network
devices try to recover the information.
