Real-Time Expert

Retransmissions and lost packets are flagged in red for quick identification. The packet

display can contain either a brief or detailed view of each packet’s contents.

To access Connection Dynamics, right-click on a conversation in either the TCP Events or

the UDP Events and select C

ONNECTION DYNAMICS. Once a conversation has been

displayed in Connection Dynamics, it can be reviewed by clicking the C

YNAMICS button on the Expert button bar.

The Connection Dynamics display consists of the graphical display and a status bar that

changes as you hover your mouse over a particular packet. When no packet is under the

mouse, the status bar displays the type of conversation in the display (TCP or UDP), the

conversation’s duration (in seconds), and packet count.

network administrator to see if there might be a problem, particularly if there are

several purple-coded packets.

• Red—a definite problem, in terms of response time, CRC error, skipped packets,

excessive retransmission, or other functionality. Real-Time Expert believes that there

is a problem with this packet, and the network administrator should investigate to
