A Life-cycle Component Management (LCM) system associated with Kubernetes can employ a universal operator to aid in the management of any software system, no matter the size or complexity. Specifically, the LCM system includes a universal operator, which eliminates the need for a human software developer to implement a set of workflows. The universal operator dynamically computes and runs the disclosed workflow set, based upon the description of the current state of the system (i.e., the 'begin state') and the new desired state of the system (i.e., the “end state”). Thereby, this universal model enables LCM for large Kubernetes software systems, which require excessive workflow sets due to the intrinsic complexity of large software systems and the plurality of vendors that contribute to such systems.

The present invention relates to a communication system and method and, more particularly, to a fault tolerant network element for providing fault tolerant call connections in the event of a failure of, for example, a Gatekeeper or other part of a network. Calls set up across a network consume large amounts of resources both throughout the network and at the devices which form the end points of the network. Therefore, even though a call connection may be supported, in the event of the failure of a network element, it is often the case that there is an ungraceful failure or use of resources throughout the network. Accordingly, an aspect of the present invention provides a method for preserving a connection context at a first layer of a communication protocol; the communication protocol comprising a second, higher, signalling layer in which, in response to a switch-over from an active host to a standby host in the event of failure of the former, the connection is terminated in response to receipt of a signalling layer signal other than a disconnect or terminate signal.
