Applications and Built-in
Diagnostic Tools
The TCP/IP protocol suite includes a number of built-in diagnostic tools that
developers provide as associated applications running under the operating
system that supports the suite. Thus, the primary focus of this chapter is on
a core set of applications that can be used to obtain insight into the flow of
data across a TCP/IP network. Through the use of the application programs
discussed in this chapter, one can determine if the protocol stack is operating
correctly on a host, whether or not a host is reachable via a network, and the
delay or latency between different networks with respect ...
