Currently, we see the following failure:
make[3]: Entering directory '/build/openbsc/tests/mgcp'
CC mgcp_transcoding_test.o
CC mgcp_test.o
In file included from ../../include/openbsc/gsm_data.h:176:0,

#include <osmocom/abis/e1_input.h>
^
compilation terminated.
as gsm_data.h includes gsm_data_shared.h, which includes the e1_input.h
from libosmo-abis, we need to list libosmo-abis in the CFLAGS.

In gsm_lchant_name(enum gsm_chan_t), use the gsm_chan_t_names value strings
from libosmocore instead of redefining the same strings. The list from
libosmocore is also more complete, including CCCH and PDTCH.
Add a todo comment to move to libosmocore.
In consequence, libosmogsm linkage needs to be added to osmo-bsc_mgcp,
mgcp_test, mgcp_transcoding_test and smpp_mirror, smpp_test.

Use the same trick as done by the dlopen check to not
have everyone link against the library.
|
|
When libosmo-netif and/or libosmo-abis are installed in distinct
prefixes, the build failed with non-found headers.

This patch moves the files relevant to transcoding from
src/osmo-bsc_mgcp to src/libmgcp and src/include/openbsc. Makefiles
and include directives are being updated accordingly.

This patch adds test cases for transcoding and repacking.

This patch adds the voice muxer. You can use this to batch RTP
traffic to reduce bandwidth comsuption. Basically, osmux transforms
RTP flows to a compact batch format, that is later on decompacted
to its original form. Port UDP/1984 is used for the muxer traffic
between osmo-bsc_nat and osmo-bsc_mgcp (in the BSC side). This
feature depends on libosmo-netif, which contains the osmux core
support.
Osmux is requested on-demand via the MGCP CRCX/MDCX messages (using
the vendor-specific extension X-Osmux: on) coming from the BSC-NAT,
so you can selectively enable osmux per BSC from one the bsc-nat.cfg
file, so we have a centralized point to enable/disable osmux.
First thing you need to do is to accept requests to use Osmux,
this can be done from VTY interface of osmo-bsc_nat and
osmo-bsc_mgcp by adding the following line:
mgcp
...
osmux on
osmux batch-factor 4
This just initializes the osmux engine. You still have to specify
what BSC uses osmux from osmo-bsc_nat configuration file:
...
bsc 1
osmux on
bsc 2
...
bsc 3
osmux on
In this case, bsc 1 and 3 should use osmux if possible, bsc 2 does
not have osmux enabled.
Thus, you can selectively enable osmux depending on the BSC, and
we have a centralized point for configuration from the bsc-nat to
enable osmux on demand, as suggested by Holger.
At this moment, this patch contains heavy debug logging for each
RTP packet that can be removed later to save cycles.
The RTP ssrc/seqnum/timestamp is randomly allocated for each MDCX that
is received to configure an endpoint.

With the current multiplication we might end up with 19999 as
time on i386. When we round it ends up as 20000 on i386 and
should work the same on AMD64.

This patch extends the test_messages test to show the number of dummy
packets that has been passed to sendto(). This way, dummy packets are
even being counted when sendto() itself failes (e.g. due to the fd
being -1).

Since automake 1.13 INCLUDES is depricates and causes a warning
|
|
The quality of the tests is of different value but it is good to
get started and improve from here.
|
|
... and make sure tests work again after restructuring
