QUESTION

I have implemented a TCP/IP application and I am using the PING utility to send periodic pings to the system. On a high ping rate it appears that packets are lost. Is this normal behaviour.

ANSWER

The TCP/IP stack provides the module ANet_Debug.c that may be used for debugging of the TCP/IP stack. When you send pings at a very high rate, the TCP/IP stack may output error text and due to the error output via a serial interface, the system may get slow.

To make sure that this is not the case on your computer, disable all debug output. Alternatively you may use a terminal program (such as Hyperterm) and analyze the debug output of your system. If there is a lot of output, your system may slow down.
