Attention is currently required from: jolly, dexter. Hello Jenkins Builder, dexter, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-mgw/+/33548 to look at the new patch set (#2). Change subject: ASCI: Support conference briding with 1..n connections ...................................................................... ASCI: Support conference briding with 1..n connections An RTP bridge may have 1 or many endpoints. Each endpoint may receive, send or echo audio back. Because transcoding is not supported, it must be assumed that only connection receives RTP in a conference with more than 2 connections. A connection that receives RTP into the endpont will have "send" pointer set to (one of) the other connection that shall send out RTP. All connection that send RTP have "send_next" pointer set to the next or first connection that sends RTP. They are linked in a ring. Regular bridge with two connections: Each connection forwards audio towards the other connection and only towards the other connection. The "send_next" pointers are set to NULL or pointing to the other endpoint. connection A connection B ("sendrecv") ("sendrecv") conn->send ---------------------------> <------------------------------------- conn->send conn->send_next ----------------------> <------------------------------------- conn->send_next Conference bridge with three connections: Each connection forwards audio to itself and also towards all other connection. connection A connection B connection C ("confecho") ("confecho") ("confecho"); conn->send --\ conn->send --\ conn->send --\ <-----------/ <-----------/ <-----------/ conn->send_next --> conn->send_next --> <------------------------------------- conn->send_next The same conference bridge but without echo: Each connection forwards auto to all other connection but not to itself. connection A connection B connection C ("confecho") ("confecho") ("confecho"); conn->send -------> conn->send -------> <------------------------------------- conn->send conn->send_next --> conn->send_next --> <------------------------------------- conn->send_next Change-Id: Ic99a55ab5a3a6170e940403fadd52697e99f2f3a --- M include/osmocom/mgcp/mgcp_trunk.h M src/libosmo-mgcp/mgcp_endp.c M src/libosmo-mgcp/mgcp_network.c M src/libosmo-mgcp/mgcp_protocol.c M src/libosmo-mgcp/mgcp_trunk.c 5 files changed, 190 insertions(+), 60 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-mgw refs/changes/48/33548/2 -- To view, visit https://gerrit.osmocom.org/c/osmo-mgw/+/33548 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-mgw Gerrit-Branch: master Gerrit-Change-Id: Ic99a55ab5a3a6170e940403fadd52697e99f2f3a Gerrit-Change-Number: 33548 Gerrit-PatchSet: 2 Gerrit-Owner: jolly &lt;andreas(a)eversberg.eu&gt; Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: dexter &lt;pmaier(a)sysmocom.de&gt; Gerrit-Attention: jolly &lt;andreas(a)eversberg.eu&gt; Gerrit-Attention: dexter &lt;pmaier(a)sysmocom.de&gt; Gerrit-MessageType: newpatchset
