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.

The present invention takes advantage of unused storage space within the ESS cells to provide for the efficient and cost effective storage of downloadable content. Specifically, the system of the present invention generally includes a download grid manager that communicates with the ESS cells. Content to be replicated to the ESS cells, and characteristics corresponding thereto, are received on the download grid manager from a content owner (or the like). Based on the characteristics, a storage policy, and storage information previously received from the ESS cells, the download grid manager will replicate the downloadable content to unused storage space within the ESS cells.

A method, system, and computer program product for implementing community messaging services is provided. The method includes calculating a receiver pool for receiving a broadcast message, the receiver pool being a subset of a messaging community. The method also includes transmitting the broadcast message to the receiver pool and tracking any feedback from the receiver pool to determine if a satisfactory response has been received. A satisfactory response results when a response is received that addresses or resolves an issue or question presented in the broadcast message. The method further includes re-calculating the receiver pool to receive the broadcast message if the satisfactory response has not been reached after a specified period of time, the re-calculated receiver pool being a subset of the messaging community that has not yet received the message.

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.

A community-defined and managed communication network is provided. The community-defined and managed network includes creating a profile for a user of the network that includes a user-selected attribute and identifying a relationship between the attribute in the profile and data external to the profile. The identification includes analyzing user community-generated descriptors of the attribute and searching the external data for common descriptors. The community-defined and managed network further includes initiating an activity responsive to the analysis, which includes one or more of: prompting the user to invite a second user who is not a registered member of the communication network to join the communication network; prompting a third user to evaluate the user with respect to the attribute; and prompting the user to initiate a communication with a fourth user who is a registered member of the communication network.

The invention concerns apparatus and methods that determine availability and performance of entities providing services in a distributed system using filtered service-consumer feedback. In particular, apparatus and methods of the invention filter service-consumer feedback in order to reduce the effect of circumstances unique to individual service consumers or to groups of service consumers that do not accurately reflect the actual availability or performance of service-providing entities. In this way an accurate appraisal is gained regarding the performance and availability of a service-providing entity. Reactive methods of the invention can be combined with proactive methods such as, for example, active status probing, to further improve the accuracy of data concerning the status and availability of service-providing entities.
