The source files in this directory are copies of the programs that were
written for the Libtrace tutorial presented at PDCAT'08. Each demonstrates
a different feature of the Libtrace programming API, often by building upon
the previous examples.
The slides that accompany these programs can be found at
http://wand.net.nz/trac/libtrace/wiki/PDCAT08
Below is a full list of the examples in order of increasing complexity, along
with a brief description of the API features that are covered by each program.
createdemo:
Demonstrates how to create and start an input trace, plus how to detect
and handle errors with trace files.
readdemo:
Demonstrates how to read packets from an input trace.
timedemo:
Demonstrates how to get and use timestamps from packets.
lengthdemo:
Demonstrates how to get and use the different packet size measurements.
sourcedemo:
Demonstrates how to use the port, IP address and MAC address access
functions.
gettcpdemo:
Demonstrates how to use the protocol access functions.
writedemo:
Demonstrates how to create and start an output traces, and how to
write packets to the output trace.
filterdemo:
Demonstrates how to use BPF filters within Libtrace.
configdemo:
Demonstrates how to use the configuration system to configure both
input and output traces before starting them.
httpcount:
Demonstrates how to use the generic trace_get_transport function
rather than the shortcut trace_get_tcp shown in gettcpdemo
mplscount:
Demonstrates how to access a second link layer header using
trace_get_payload_from_layer2
mplstag:
Demonstrates how to iterate through multiple link layer headers.
headerdemo:
A much more complicated tool that puts a lot of the previously
demonstrated concepts together to create a useful tool.
