Automated topology formation in a dynamic distributed environment. The automatic topology formation includes receiving by an application of a first entity having an initial topology role, topology information from a master node. The first entity has an initial topology role and the received topology information varies based the initial topology role. A local topology representation information is derived from the received topology information wherein the local topology representation information comprises any one of: a first entity topology role as any one of a not-a-node, root node, a prime node or a leaf node for the topology; a list of entities that are parents of the first entity in the topology, or a list of entities that are subordinates to the first entity in the topology; and setting the local topology representation information at the first entity.

Automated topology formation in dynamic distributed environments

A method for automated topology formation in a dynamic distributed environment includes configuring a master node in an active topology having nodes and intercommunication paths between the nodes. The master node includes an automated topology formation application including a predefined topology policy definition and a representation of the active topology. The master node receives a communication from an entity, the communication including a topology event notification indicating an event affecting the active topology. Using the automated topology formation application, it is determined that the topology event notification affects a topology portion of the active topology and, based on the topology event notification, the representation of the affected topology portion of the active topology is modified according to the predefined topology policy definition.
