Verifyingcommunication protocol
SMART Bridgit software uses threet ypes of network protocols:
lTCP for data andvideo
lUDP for VoIP audio
lHTTP if a client is unable to connect to the server using TCP
Communicationsusing TCP and UDP have lower network delays than those usingH TTP protocol,
andusing them helps to preventlatency issues.
Use SMART Bridgit software’s troubleshootingtool to determinet henetwork protocol you’re using.
SeeU singt heSMAR TBridgittroubleshootingtool on page58.
Ensurethat values appearin t heTCP P ort andUDP Port f ields. If these fields have N/A in them, or if
theProxy Connection option is selected, contact your administratort o openthe TCP and UDP ports
to connectt o SMART Bridgit server. See Administeringthe server software on page 37. See
SMARTBridgitand firewalls on page 11 for informationabout configuringfirewalls and proxy servers.
Checkingfor firewalls
gTo determinei f theclient is behind a firewall
1. On the client computer,open the SMART Bridgit troubleshootingtool. See Using the
SMARTBridgittroubleshootingtool on page58.
TheConnection area displays the ports andprotocols the client computer is using to
communicatewith t hes erver.If a client is communicating througha proxy server or if the
client’s UDP and secondaryTC P ports areblocked by a firewall, t heProxy Connection check
boxis s elected.
2. Contact your administratorto open the TCP and UDP ports to connect to SMAR T Bridgit
server
Measuringlatency and packetloss
Packet loss occursw henone ormore packets of datatraveling across acomputer networkf ailto
reachtheir destination. Packet loss rates dependon factors including bandwidth, communication
pathreliability and routerbuffer size. W henpackets are lost, latency increases as the network
devices try to recover the information.
