The initial days of MMS was nothing more than JAIN SLEE Resource Adaptor (RA) on top of JMF project and was shipped with early versions of Mobicents JAIN SLEE Server. The RA was un-stable and more over JMF is project to fulfill the media needs of a desktop application. For something to truly serve the needs of telco applications we needed much more robust and scalable server. We also explored the FMJ project but that too didn't meet the requirements we had. We searched around to see if there are already existing Open Source Media Server's on top of which we can build our own or re-use it as its. But there were none and hence we decided to build our own Media Server :)

We released first Alpha version of MMS on end of Feb 2008 and took approx 13 months to come up with first stable release. Thanks to all those who has contributed, provided valuable feed-backs and big thanks to Mobicents Core Team. Last but not least a big thank you to MMS users. MMS 1.0.0.GA is the first Open Source Media Server that has passed MGCP TCK test.

MMS 1.0.0.GA has all the features from simple announcement, recording, IVR to complicated ones like Conference. MMS has support for majority of audio codecs used in industry today like PCM-U, PCM-A, G729, GSM, Speex. MMS can be easily used with JAIN SLEE Server with either MGCP Resours Abaptor or MSC Resource Adaptor or it can be integrated with Sip Servlets using the MSC API.

With release of 1.0.0.GA the life-cycle for 1.x.y comes to an end and we will be actively doing development for version 2.x.y

Going Forward....

The support for video has already begun (check out code from SVN trunk). MMS is also actively developing endpoints for SS7 support. Have a look at wiki page http://groups.google.com/group/mobicents-public/web/mobicents-ss7-roadmap. The first Alpha release of 2.0.0 will also have initial support for JSR-309. JSR-309 is protocol agnostic API for Media Server Control. The MMS implementation for JSR - 309 will be on top of MGCP.

Mobicents Media Server Performance better than targeted for GA release

Just few days back MMS CR6 was released with much improvements on performance. I did a quick performance test of CR6 using SipP tool for load generation, a wonderful tool called sysstat for CPU recording http://pagesperso-orange.fr/sebastien.godard/tutorial.html#section1 and our own tool for RTP Jitter recording.

The test was run for approximately 10 min with intention to measure the jitter at load of 100 ~ 110 concurrent announcements and at same time measure the CPU usage on MMS Server.

While the Jitter was under control the CPU never crossed more than 25%. The attached graph shows the idle% CPU recorded after every 5 secs.

Here are the jitter graphs taken randomly while running the test tool.
