Abstract: Systems and methods for allocating assets to a plurality of devices are presented. In one embodiment, devices may be communicatively connected to one another through a device loop. Each device may be configured for determining a portion of an asset that it will use. A controller may also be communicatively connected to the communication medium and configured for determining a capacity of the asset.

In another embodiment, each of the devices may be communicatively connected directly to the controller rather than to one another.

Abstract: The present invention extends to methods, systems, and computer program products for optimizing access to federation infrastructure-based resources. Various different layers within a federation infrastructure can signal location change events indicating the hosting location and/or access location for a resource is to be optimized. In response to a location change event, redirection information for accessing the resource is updated within the federation infrastructure. The redirection information is used to redirect resource access requests to appropriately optimized locations within the federation infrastructure. Redirecting resource access requests reduces communication within the federation infrastructure.

Abstract: A common access ring (CAR) network includes a main ring and one or more sub-rings. The main ring includes one or more masters, one or more slaves, and one or more bridges. Each sub-ring is coupled to the main ring through a corresponding bridge. Each node of the CAR network is assigned a unique identifier, thereby implementing a global flat address space. One or more masters may issue requests on the CAR network, such that multiple transactions are simultaneously pending. Multiple masters may simultaneously issue requests to the same slave. However, each master cannot make more than one request at a time, and must wait until a current request is completed before making another request. The ring architecture ensures that no more than one request arrives at a slave at any given time. Requests received by busy slaves are returned to the originating masters, and may be subsequently re-sent.

Abstract: A common access ring (CAR) architecture that supports multiple masters and slaves is provided. One or more masters may make a request on the ring at the same time, such that multiple transactions are simultaneously pending. Moreover, multiple masters may simultaneously make a request to the same slave. However, each master cannot make more than one request at a time, and must wait until a current request is completed before making another request. The ring architecture ensures that no more than one request arrives at a slave at any given time. If a request arrives while a slave is processing a previous request, the arriving request is not serviced, and the master that originated the arriving request is asked to retry the request at a later time. Atomic shadow-write operations are supported by including all shadow registers in a dedicated sub-ring of the CAR architecture.

A tunnel interface may optionally be applied to a data packet upon egress.

Abstract: The present invention extends to methods, systems, and computer program products for broadcasting communication within a rendezvous federation. Embodiments of the invention include inter-ring and intra-ring communication. Inter-ring communication includes sending a message to destination rings included in a node's Collateral Ring Set entry table. When a node identifies a destination ring that has not yet received a message, the node can send a ring notification message. The ring notification message propagates towards a publishing node until a responsible node in the message path to the publishing node is identified. The responsible node updates its entry table to include the ring and forwards the message to the destination ring. Intra-ring communication can include recursively partitioning ranges of nodes within a ring and forwarding the message to nodes included the partitioned ranges.

The transmission apparatus determines whether any transmission apparatus has already been registered as parent apparatus in the child apparatus, and also determines whether the designated parent apparatus has already been registered as a child apparatus in the child apparatus. The transmission apparatus then requests the designated parent apparatus to transfer the control data in the designated parent apparatus to the child apparatus, when the designated parent apparatus is not registered in the child apparatus.
