Memory/Hardware Requirements - Snom ONE IP Technical Manual

Deploying the snom ONE IP Telephone System
2
The system is easily portable to most operating systems and requires only a small
amount of memory. Due to the need for speed, snom technology does not use a tradi-
tional database to store its information. Doing database lookups can be slow in a very
busy system. Having a data structure in memory with the necessary information to
authenticate a phone is much faster.
The snom ONE telephone system is a software-based solution and executes several mea-
sures to preserve call quality:
•
A high-scheduling priority is used with applications that are real-time critical.
•
The snom ONE measures CPU usage and rejects calls if the load becomes too
high.
•
When too many calls are coming in during a short period (call bursts), the
system also rejects calls.
While these measures are important, the performance of the software depends largely
on the hardware being used.

Memory/Hardware Requirements

The snom ONE system consumes only a small amount of memory. In the image shown
below, a snom ONE system uses under 50 MB of RAM, which is not unusual for a
lightly loaded system.
