- Improved Cluster Support with fine-grained data per Diameter Application;
- Support for more 3GPP Applications (Gq', Rx, Gx, S6a) and improved/updated existing;
- Support for Diameter RELAY / PROXY / REDIRECT Agents;
- Performance improvement of over 9 times (now handling up to 9000 requests/second in Dev Machine, C2D @ 3.06GHz / 4GB RAM, no special setup);
- Added several configuration parameters to optimize for different scenarios (regular usage vs high load vs small footprint, etc);
- 100+ miscellaneous fixes to improve overall compliance and stability of the Mobicents Diameter Stack and it's JAIN SLEE Resource Adaptors;
- Also important, Mobicents (including Diameter) license has changed from GPL to LGPL, which is generally good news for the users!
Still, there's a lot of work and improvements to be done for the upcoming 1.4.x series. To name a few:
- Support for TLS security in Mobicents Diameter Stack (existing in 1.4.0.FINAL as experimental);
- Support for SCTP transport in Mobicents Diameter Stack (initial patch already contributed);
- Support pluggable Load Balancing algorithms for Mobicents Diameter Stack; Integrate with Mobicents Load Balancer;
- Create integration/real-world examples, eg, integrate with Mobicents JAIN SLEE B2BUA, continue work on Mobicents HSS and integrate it with Mobicents SIP Presence;
- Improve documentation for developers using Mobicents Diameter Stack;
As you can see, there's a lot that has been improved but there's also a lot more to improve on, with our ambition aiming higher. Feel free to help us with your feedback and contributions to a better Mobicents Diameter!
