Service Creation Environment (SCE ) for SIP Applications

I hoped of making a SIP application Development environment a year back and worked towards it earnestly . Sadly I wasn’t able to complete the job yet I have decided to share a few things about it here .

Aim :

Develop  a SCE ( Service Creation Environment ) to addresses all aspects of lifecycle of a Service, right from creation/development, orchestration, execution/delivery, Assurance and Migration/Upgrade of services.

Similar market products :

• Open/cloud Rhino
• Mobicents and Telestax

Limitations of open source/other market products:

• Free versions of the Service Creation Environments do not offer High Availability.
• High Cost of Deployment grade versions.

Solution Description

I propose a in-house Java based Service Creation Environment “SLC SCE”. The SLC SCE will enable creation of JAINSLEE based SIP  services. It can be used to develop and deploy carrier-grade applications that use SS7 and IMS based protocols such as INAP, CAP, Diameter and SIP as well as IT / Web protocols such as HTTP and XML.

Benefits:

• Service Agility
• Significantly Lower price points
• Open Standards eliminate Legacy SCP Lock-in

Timeline

• Java-based service creation environment (SCE) – 1.5 Months
• Graphical User Interface (GUI) and schematic representations to help in the design, maintenance and support of applications – 1.5 months
• SIP Resource Adapter – 1 month

Architecture

In essence it encompasses the idea of developing the following

1. SIP stack
2. Javascript API’s
3. Java Libraries for calling SIP stack
4. Eclipse plugin to work with the SIP application development process
5. Visual Interface to view the logic of application and possible errors / flaws
6. SDKs (  Service Development Kit) , which are development Environment themselves

Extra Effort required to put in to make the venture successful

1. Demo applications for basic SIP logic like Call screening , call rerouting .
2. tutorial to create , deploy and run application from scratch . Aimed at all sections ie web developer , telecom engineer , full stack developer etc .
3. Some opensource implementation on public repositories like Github , Google code , SourceForge
4. Perform active problem solving on Stackoverflow , CodeRanch , Google groups and  other forums .
