Process for Detecting the Availability of Redundant Communication System Components

A method for detecting the availability of system components of a communications system, comprising:

• providing a plurality of hardware devices that operate the system components of the communication system at least in duplicate,
• wherein a portion of the components are active in the normal mode of the communication system, and
• wherein a portion of the components are redundant system components operating in standby mode and the redundant system components taking over the function of the previous actively components in the event of failure of at least one of the plurality of hardware devices;
• combining, relative to function or task, the system components and at least a communication channel, a software process and data used by the relative component into resource groups;
• wherein each resource group adapted to run on at least two hardware devices and, in normal mode and to verify the availability of the system components,
• wherein one resource of the resource groups is active on precisely one single hardware device, and
• wherein at least one redundant resource group is operated in standby mode on at least one other hardware device;
• and
• automatically replicating the data of the active resource group to the data of the redundant resource group.
