Abstract: A system, method and computer-readable medium by-passing the public switched telephone network when routing a call from a carrier network to an enterprise network are provided. A carrier gateway server is communicatively coupled with an enterprise gateway server. The enterprise gateway server is adapted to publish direct inward dial numbers assigned to enterprise extensions to the carrier gateway server. Once published, call setups originated in the carrier network may be routed directly to an enterprise network having a terminal assigned the dialed number of the call setup. Advantageously, the carrier network operator does not incur any inter-connect fee from any public switched network operator.
Abstract: The invention pertains to communication among stations interconnected by a ring of physical links, operating at a base symbol rate. Each station has an upstream and a downstream link and relays messages originating from the upstream link to its downstream link. Logical links are provided on the ring, each associated with a symbol rate divisor and a link index. Each station transmits messages composed of a strings of symbols on a selected logical link by transmitting the message on its downstream link at the base symbol rate divided by the symbol rate divisor associated with the selected logical link, and offset by the link index of the selected logical link.

Abstract: The application relates to allocating transmission resources in communication networks that provide low latency services. A terminal receives, from a base station time-frequency resource division information, which indicates a division of a time-frequency resource that is allowed to be used by another service. The division of the time-frequency resource includes one or more resource units in time domain and one or more resource units in frequency domain. The terminal further receives from the base station time-frequency resource indication information, which indicates that, in the time-frequency resource that is allowed to be used by the other service, at least one time domain resource unit and at least one frequency domain resource unit are occupied by the other service. The terminal communicates with the base station using the time-frequency resource except the at least one time-domain resource unit and at least one frequency-domain resource unit that are occupied by the other service.
Abstract: Techniques are described for using compositional reasoning techniques to perform role reachability analyses relative to collections of user accounts and roles of a cloud provider network. Delegated role-based resource management generally is a method for controlling access to resources in cloud provider networks and other distributed systems. Many cloud provider networks, for example, implement identity and access management subsystems using this approach, where the concept of “roles” is used to specify which resources can be accessed by people, software, or (recursively) by other roles. An abstraction of the role reachability analysis is provided that can be used as input to a model-checking application to reason about such role reachability questions (e.g., which roles of an organization are reachable from other roles).

Abstract: A method and system for allocating tasks among processing devices in a data center. The method may include receiving a request to allocate a task to one or more processing devices, the request indicating a required bandwidth for performing the task, a list of predefined processing device groups connected to a host server and indicating availability of the processing device groups included therein for allocation of tasks and available bandwidth for each available processing device group, assigning the task to a processing device group having an available bandwidth greater than or equal to the required bandwidth for performing the task, and updating the list to indicate that each of the processing device group to which the task is assigned and other processing device group sharing at least one processing device is unavailable. The task may be assigned to an available processing device group having a lowest amount of power needed.

Abstract: Methods, devices and systems are provided for performing a random access (RA) procedure. A wireless transmit/receive unit (WTRU) may be configured to receive RA resource sets, where each of the RA resource sets is associated with a node-B directional beam, select an RA resource set from among the RA resource sets, and initiate an RA procedure based on the selected RA resource set. The RA procedure may include selecting multiple preambles which include a preamble for each resource of a plurality of resources corresponding to the selected RA resource set. The WTRU may be configured to sequentially transmit the selected multiple preambles in sequential RA transmissions, and may be configured to receive, from a node-B, in response to the RA transmissions, at least one RA response (RAR), where each of the received at least one RAR corresponds to one of the transmitted multiple preambles.

Abstract: In one embodiment, a device obtains, from a plurality of routers in a network, a set of routing patches that collectively specify a first set of paths in the network, a second set of paths in the network, and time periods during which traffic is to be rerouted from one of the first set of paths to one of the second set of paths in the network. The device identifies overlapping path segments of the second set of paths in the network. The device makes, based in part on the overlapping path segments, a prediction that two or more of the set of routing patches will cause congestion along paths with overlapping path segments. The device adjusts, based on the prediction, the set of routing patches, to avoid causing the congestion.

Abstract: This disclosure describes techniques for managing path counts at a router. The techniques include monitoring available storage space at a router for storing per prefix routes. In an instance where the available storage space at the router may be inadequate to support continued, stable network operations, the techniques include reducing an amount of per prefix routes that are advertised to the router. The techniques may also include withdrawing previously advertised per prefix routes from the router. As such, path count management concepts may help prevent overload of storage space at a router.
Abstract: Provided are a data transmission method, apparatus and computer readable storage medium. The method includes: sending, by a terminal, a random access preamble to a base station, and receiving a random access response sent by the base station; and sending, by a terminal, a first request message carrying uplink data to the base station.
Abstract: In the method of present application, a terminal device obtains resource indication information. The resource indication information indicates frequency domain resources of a data channel of a terminal device. The resource indication information comprises S bits, where S is a positive integer. The terminal device determines the frequency domain resources of the data channel of the terminal device based on the resource indication information.
Abstract: A network element includes at least one communication port and a processor. The communication port is configured to communicate with a peer communication port of a peer network element. The processor is configured to support a full-boot mode and a fast-boot mode, to establish, by negotiation with the peer network element, whether the fast-boot mode is supported both for the communication port and for the peer communication port, and, in response to finding that the fast-boot mode is supported both for the communication port and for the peer communication port, to coordinate with the peer network element a boot of the communication port and of the peer communication port, both using the fast-boot mode.
