Mobicents SIP and HTTP Load Balancing

The topic of High Availability and Fault Tolerance is always interesting as the set of use cases evolves and the infrastructure available to support various solutions varies. Vladimir Ralev, Mobicents architect, discusses some essential aspects of SIP Load Balancing and converged SIP + HTTP load balancing in a pretty thorough presentation (42 slides):



Comments to this exciting topic are most welcome.

Mobicents Cloud Communications

For the last 6 months there has been a great amount of activity in the Mobicents community on the topic of Cloud Communications.

To provide an overview of our current state and future roadmap to community members interested in the topic, we created a short (under 4 minutes) video.

For a more technical discussion of Mobicents for Cloud Communications, take a look at the research thesis by Thibault Leruitte at Universit e catholique de Louvain: Migration of Mobicents SIP Servlets on a Cloud Platform.

As always, looking forward to feedback, criticism, suggestions and most of all code contributions :)

Rancore Technologies wins Red Hat Innovation Award

Congratulations to Aayush Bhatnagar and his team at Rancore Technologies for winning the 2011 Red Hat Innovation Award for Outstanding Open Source Architecture! This is a well deserved acknowledgment for a cutting edge telecom platform for 4G/LTE networks and applications. I am happy to have Aayush on the Mobicents core team. His input is essential to the project's roadmap, priorities and architecture.

A few excerpts from the award web page:

"Headquartered in Navi Mumbai, India, Rancore Technologies a leading technology R&D firm focused on 4G telecom networks and services. Rancore is a privately held company and a subsidiary of Reliance Industries Limited (RIL), a fortune 500 firm and India's most valuable company."

"Telecom features and services were implemented on top of the Mobicents Stack (JAIN SLEE) which was in-turn deployed on JBoss Application server. Mobicents provided a rich suite of resource adaptors which acted as Telco protocol connectors. JAIN SLEE RAs such as HTTP, XCAP, SIP, SMPP and DIAMETER were extensively used in the products. Rancore also contributed code, patches, bug fixes and knowledge to the Mobicents community and hence acquired a seat in the Mobicents core team."

"This project is going to be part of one of one of the largest 4G LTE/IMS deployments in the world - and in the world's biggest telecom market – India. Rancore's SDP is designed to be suitable for mission critical 4G deployments, where high throughput and low latency are desired. By showing quite clearly that a low-cost, high-throughput, mission- critical fault tolerant system can be built with the right use of open source technology, Rancore is the first company in India to utilize open source technology to build a Service Delivery Platform based on 4G standards. Lastly, Rancore has also contributed code, patches, bug fixes and knowledge to the Mobicents community - a strong testament to its belief in open source philosophy."

Congratulations, Aayush! Looking forward to hearing more about the market success of Rancore Technologies.

LGPL 2.1 license for all Mobicents projects: effective March 1, 2011

The Mobicents team has decided to align its licensing policy with the rest of the JBoss projects and convert all of its source code files to LGPL 2.1 Open Source license.

The decision is effective immediately!

I would like to thank everyone who has shared their thoughts on this subject over time. Congratulations to all LGPL advocates who have made their arguments clear. Victory well deserved! :)

Do you have a cool Mobicents based application? Let's show it to the world!

JBoss World 2011 is around the corner. It will be the biggest JBoss event ever. If you have a great telco app based on Mobicents, let me know. We will work together to propose it for the show floor at JudCon - the Alpha Geek event preceding JBoss World. All proposals have to be compiled by the end of February 2011. Let's not waste time. Let the best and bravest stand out!

OKI Japan becomes core contributor to Mobicents

After several years of active engagement with the Mobicents community, OKI Japan, one of the pioneers of the SIP Servlets technology, made a decision to contribute a hugely useful telco developer framework. It allows Web developers, to quickly add telecom features to their applications, without going through a steep learning curve. I am very happy to welcome OKI to the Mobicents Core team. You can learn more from the OKI press release: http://www.oki.com/en/press/2010/06/z10009e.html.
