Chapter 4 - MultiVOIP Software
Control Protocol (TCP) is a connection-oriented transport layer protocol used with FTP, Telnet, and
SNMP.
UDP makes use of the port concept and has no measures for flow control, reliability, or error recovery.
It is used when the full services of TCP are not required, and the reliability measures must be
assumed by another layer.
TCP works well in environments where the reliability measures are not assumed by other layers. It is
connection-oriented and has a full range of services.
For the most part these statistics are informational, and their use as a troubleshooting tool will be
contingent on the applications running in the upper layers. For example, if you were having problems
connecting to the MultiVOIP's web server, you would look under the TCP section to see if any
connections are being established. If not, that may indicate the web server is not enabled. Or, if you
were having problems establishing a remote connection through TFTP, you could look in the UDP
section to see if any packets are being received. If not, you may need to review your network
addressing.
