| This article will describe the TelcoBridges High Availability feature. The hardware and software are design with the following 2 goals in mind:
| |
| | |
| # First and foremost, to recover from a system failure to minimize the system down time or instability as much as possible. This is achieve with a fault tolerant and redundancy architecture.
| |
| # Secondly, to keep active calls open after a fail-over whenever possible.
| |
| | |
| | |
| | |
| == TelcoBridges High Availability ==
| |
| | |
| TelcoBridges High Availability should be seen as a collection of high availability and redundancy features instead of one single feature. This means that customer can go as little or as far as they want to create a high availability system.
| |
| | |
| == Definitions ==
| |
| | |
| Here is a list of terms used in the description of the high availability features:
| |
| * [[Primary/Secondary]]
| |
| * [[Master/Slave]]
| |
| * [[Active/Standby]]
| |
| * [[Load Sharing]]
| |
| * [[Switchover]]
| |
| * [[Switchover Period]]
| |
| * [[Active Calls]]
| |
| * [[Transient Calls]]
| |
| * [[Resynchronization]]
| |
| | |
