[Serusers] SER or OpenSER

[Daniel-Constantin Mierla]

I will add few remarks related to project's policy and evolution.

OpenSER is driven by a board with members from different companies which
will ensure project's independence and survival when one company changes
its interest in the public project. Also, the project has a clear
roadmap, major changes being discussed on development mailing list.
People leading the project are two of the five core developers of SER
and four main contributors of SER.

The release policy is guided by changes and it is about one major
release every 6-8 months. This type of releasing allow easy migration
from older version to new one, otherwise the administrators will have
nightmares to update to totally new configuration and database structure
- small steps guarantee better results when dealing with production
environments.

The contributions are accepted if they follow a recognized standard from
IETF/ITU/ETSI or other standardization groups, or is general interesting
feature. No company can stop it for private interest.

In this way we are able to implement geographic distributed VoIP
platforms with the latest OpenSER, have a significant number of database
types supported as backend via the unixodbc module in the stable
version, these and may others only from third party contributions. Other
important scalability features added in about one year of OpenSER:
number of location entries which can be managed by OpenSER compiled with
default flags grew from about 4000 entries as it was when it forked from
SER to about 120 000, and now this number scales linear with available
memory (for 120000 online users, OpenSER uses about 40MB memory, while
the old architecture required about 256MB). I am sure you can find more
on project's web site ...

Cheers,
Daniel
