Description of various IP stack test applications
|
||
|
|
=================================================
|
||
|
|
|
||
|
|
echo_server
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The echo server test implements a network server that listens
|
||
|
|
UDP sockets. If that socket receives data, the server reverses
|
||
|
|
the data and sends it back.
|
||
|
|
|
||
|
|
The echo client can be running in the host system in which
|
||
|
|
case you need to use SLIP to connect to qemu. This usage scenario
|
||
|
|
is described in net/ip/tools/README file. This is the default
|
||
|
|
if you type "make qemu" in echo_server test application directory.
|
||
|
|
The network IP stack hooks right under IP stack (network level)
|
||
|
|
and sends the IP packet to host using SLIP. The layer 2 is the
|
||
|
|
SLIP layer in this case, no radio layer is simulated or used.
|
||
|
|
|
||
|
|
The echo server qemu instance can also be running against echo
|
||
|
|
client that is running in another qemu. For this you need two
|
||
|
|
terminal windows. In terminal 1 go to echo_server directory
|
||
|
|
and type "make server". This will start the echo server and setup
|
||
|
|
qemu pipes in suitable way and it will also start monitor application
|
||
|
|
that will store the transferred network traffic into pcap file
|
||
|
|
for later analysis. Then in terminal 2 go to echo_client directory and
|
||
|
|
type "make client". This will start the echo client that will
|
||
|
|
start to send data to the server and verify that it has received
|
||
|
|
the data back correctly. In the two qemu case we are simulating
|
||
|
|
the whole radio network meaning that the saved pcap file will
|
||
|
|
contain 802.15.4 network packets.
|

||
|
|
echo_client
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The echo client test implements a network client that will
|
||
|
|
send UDP data to the echo server. The client verifies that
|
||
|
|
it has received data to the sent message and that the data
|
||
|
|
is correct.
|
||
|
|
|
||
|
|
The echo server can be running in the host system in which case
|
||
|
|
you need to use SLIP to connect to qemu. This usage scenario
|
||
|
|
is described in net/ip/tools/README file. This is the default
|
||
|
|
if you type "make qemu" in echo_client test application directory.
|
||
|
|
The network IP stack hooks right under IP stack (network level)
|
||
|
|
and sends the IP packet to host using SLIP. The layer 2 is the
|
||
|
|
SLIP layer in this case, no radio layer is simulated or used.
|
||
|
|
|
||
|
|
The echo client qemu instance can also be running against echo
|
||
|
|
server that is running in another qemu. This test scenario is
|
||
|
|
described in echo_server chapter above.
