Measurement Surveys
NOTE
These fields are only displayed when data transfer is happening between the Client – AP link. Data transfer must be
enforced by the user. For more information, check the section "Enforcing data transfer and Server-coupled
Measurements".
Data Tab.
This tab appears while using AP Performance Server data transfer method only.
The Data tab contains the following information and options:
Statistics/Value - Displays the following real-time measurement data statistics:
●
My IP Address - IP address of the machine that the client is running on.
■
My Name - Displays the network name associated with the client's machine.
■
Maximum Bandwidth - Throughput in bits per second that the TCP Stream protocol attempts to
■
match its bandwidth usage. This setting is only used by the TCP Stream mode. Note that this is
not the actual throughput, only an upper limit that the AP Performance Server attempts to match
the actual throughput to. This upper limit can be changed by using the TCP Stream Configure
option on the Network tab
Auto Logging Status - This option indicates whether the client has enabled or disabled auto
■
logging.
Auto Logging Interval - This option displays the information how often the client saves data
■
markers if auto logging is enabled.
Network Tab.
This tab appears while using AP Performance Server data transfer method only.
The Network tab contains options and provides information for:
Connecting to a Measurement Server.
●
Setting the Protocol mode for TCP and UDP measurements:
●
Protocol.
TCP Stream: Configure - Opens the TCP Stream Setup dialog box. From this dialog box, you can
●
modify the Client/Server Packet Size, specify the TCP packet Maximum Bandwidth Usage, and adjust the
packet Averaging Interval. The TCP Stream protocol calls for the client and server to exchange
information using TCP over IP instead of UDP packets. Most common network applications such as
browsing the web, performing file transfers, and checking E-mail are all TCP-based programs.
The packet size settings that you can change are the packet size that the client sends to the server
●
(Client Packet Size) and the packet size that the server sends back to the client (Server Packet Size.)
The packet size is the number of bytes of raw data in every packet that is sent. By selecting one of
these options from the Packet Size drop-down list you can set the amount of data sent in the
payload of a test packet.
The Maximum Bandwidth Usage setting allows the TCP Stream client to match real bandwidth usage
●
with the value that you specify from the drop-down menu. This allows Summit WMScanner to be
tailored to simulate the bandwidth usage of a wide range of network applications and users. The
Averaging Interval alters how long a client will average network statistics before sending results to
the server.
