Methods and systems are disclosed for communicating in a wireless communications system utilizing a plurality of frequency bands for downlink (DL) transmission and a plurality of frequency bands for uplink (UL) transmission. In an embodiment, a mobile device receives a DL signal via a DL frequency band. The DL signal contains DL-UL frequency-band association information. The DL signal is decoded to obtain the DL-UL frequency-band association information which is used to determine a UL frequency band for UL transmission. The mobile device configures its radio-frequency (RF) circuitry to operate in the UL frequency band for UL transmission.

A network slice managing entity, comprising means configured to obtain a service request for a network slice, the service request defining service requirements; request network slice descriptions from a database and selecting at least one network slice which support said service requirements according to the descriptions; generate a resource graph comprising nodes representing infrastructure resources and links representing connections between the nodes, the resource graph depicting resources needed for providing the service, wherein the generating is carried out based on a network slice description of the selected at least one network slice; transmit the resource graph to an infrastructure manager for mapping a topology of said network infrastructure onto said resource graph and determining at least one subset of said network infrastructure; and, receive a mapping result from said infrastructure manager containing said at least one subset of said network infrastructure.

In some examples, a control network for one or more network segments of a network comprises a plurality of controllers each including one or more processors. The plurality of controllers receive service requests that each comprises a definition for a service provided by the network to connect at least two endpoints over a path traversing at least one of the one or more network segments, wherein the control network operates according to a control model by which the plurality of controllers provision services in the one or more network segments to satisfy the service requests. The plurality of controllers dynamically adapt, based on network conditions including the service requests, the control model for the control network. The plurality of controllers provision, according to the adapted control model, services for the service requests.

A system includes a plurality of agents to control managed equipment of a geographically distributed data center. A controller communicates management data with the plurality of agents via a management network. The controller and the plurality of agents are configured in a hierarchical topology. A first subset of the plurality of agents relay management data on behalf of a second subset of the plurality of agents. The controller is further configured to: communicate with a new agent to be provisioned into the plurality of agents; generate reconfiguration instructions that indicate an allocated parent agent of the plurality of agents to be associated with the new agent; and facilitate a provisioning of the new agent in accordance with the reconfiguration instructions, to connect the new agent to the allocated parent agent of the plurality of agents via the management network and disconnect the new agent from the controller.

Technologies for composing a managed node with multiple processors on multiple compute sleds to cooperatively execute a workload include a memory, one or more processors connected to the memory, and an accelerator. The accelerator further includes a coherence logic unit that is configured to receive a node configuration request to execute a workload. The node configuration request identifies the compute sled and a second compute sled to be included in a managed node. The coherence logic unit is further configured to modify a portion of local working data associated with the workload on the compute sled in the memory with the one or more processors of the compute sled, determine coherence data indicative of the modification made by the one or more processors of the compute sled to the local working data in the memory, and send the coherence data to the second compute sled of the managed node.

Disclosed herein are various embodiments for constructing an abstract domain topology. In one embodiment, a Path Computation Element (PCE) is configured as a parent PCE to at least one child PCE. Each of the child PCEs is responsible for providing path computational services for a domain. Communication is established between the parent PCE and the at least one child PCE. The parent PCE receives from each of its child PCEs domain connection information corresponding to the domain of each child PCE. The parent PCE builds and maintains an abstract domain topology based on the domain connection information that it receives from its child PCEs. In one embodiment, the domain connection information is communicated from the child PCE to the parent PCE by adding a new notification-type (NT) and notification-value (NV) to a notification object in a Path Computation Element Communication Protocol (PCEP) notification message.

Initializing a graph for providing proof of space includes generating an initial graph at a device. The initial graph is acyclic. Content of a first node in the initial graph is generated based at least in part on (1) a predecessor node that is a predecessor of the first node and (2) on a godparent node. A position of the godparent node is based at least in part on content of the predecessor node. It further includes storing at least a portion of the initial graph on the device.
