Redundancy & High Availability: Difference between revisions

Revision as of 12:49, 14 February 2011

This article describes TelcoBridges' VoIP Gateway high availability features. TelcoBridges' products 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 & Redundancy

TelcoBridges High Availability & Redundancy should be seen as a collection of 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:

TMG800 Features

TMG3200 Features

TMG7800 Features

Installation, Maintenance and Provisioning

This section will show how to install, upgrade and configure a high availability system.

First, we will look at the software installation and provisioning (Host redundancy).

Installing a host redundancy system

Upgrading a host redundancy system

Configuring a host redundancy system
