Abstract: Methods, systems, and devices for wireless communications are described for a two-step random access channel (RACH) procedure in which uplink random access preamble and message transmission occasions may span multiple transmission slots. Reference signal resources for transmitting a reference signal with a first random access message of the two-step RACH procedure may include at least one symbol in each of the multiple transmission slots. The reference signal resources, reference signal sequence, or both, may be identified based on a particular uplink random access message transmission occasion, random access preamble transmission occasion, random access preamble sequence configuration, or any combinations thereof.

Abstract: Systems and methods for providing multicast group (MCG) membership relative to partition membership in a high performance computing environment. In allowing a subnet manager of a local subnet to be instructed that all ports that are members of the relevant partition should be set up as members for a specific multicast group, the SM can perform a more efficient multicast-routing process. It is also possible to limit the IB client interaction with subnet administration conventionally required to handle join and leave operations. Additionally, subnet manager overhead can be reduced by creating a spanning tree for the routing of multicast packets that includes each of the partition members added to the multicast group, instead of creating a spanning tree after each multicast group join request is received, as conventionally required.

Abstract: The disclosure relates to methods for improving the DRX operation of a UE by introducing an additional DRX wake-up cycle, which runs in parallel to the short and/or long DRX cycle. The DRX wake-up cycle defines time intervals after which the UE starts monitoring the PDCCH for a wake-up duration of time; the UE does not perform any other operation during the wake-up duration apart from monitoring the PDCCH. The time intervals of the wake-up cycle between the wake-up durations are preferably shorter than the one of the DRX long cycle, and may have the same or a shorter length than the ones of the DRX short cycle. The wake-up duration may be as long as the on-duration of the DRX short/long cycle, or may be preferably much shorter, such as only one or a few subframes.

Abstract: A system of multi-modal transmission of packetized data in a voice activated data packet based computer network environment is provided. A natural language processor component can parse an input audio signal to identify a request and a trigger keyword. Based on the input audio signal, a direct action application programming interface can generate a first action data structure, and a content selector component can select a content item. An interface management component can identify first and second candidate interfaces, and respective resource utilization values. The interface management component can select, based on the resource utilization values, the first candidate interface to present the content item. The interface management component can provide the first action data structure to the client computing device for rendering as audio output, and can transmit the content item converted for a first modality to deliver the content item for rendering from the selected interface.

Abstract: An information processing apparatus and a communication terminal can carry out first wireless communication and second wireless communication. The first wireless communication is established when a distance between the information processing apparatus and the communication terminal is equal to or less than a first distance. The information processing apparatus determines whether data communication is to be carried out over the first wireless communication or the second wireless communication. When the data communication is to be carried out over the first wireless communication, the information processing apparatus carries out the data communication over the first wireless communication.

Abstract: Aspects of the present disclosure include systems, methods, computing devices, computer-implemented methods, and the like for modeling and/or simulating performance of a telecommunications network during one or more failure scenarios that reduces computational time and/or power over previous simulation techniques. Modeling and simulating the network may include generating an initial network model from network data information and applying one or more transformations to the initial network model to reduce the size of the model. Following transformation, simulation methods may be applied to the generated network model based on routing characteristics of the components of the network. To reduce the computations utilized to simulate such components and/or routing decisions in the network, one or more simulation algorithms may be applied to the transformed network model to reduce the number of routing decisions simulated.

Abstract: A system for facilitating enhanced virtual channel switching in a node of a distributed computing environment is provided. During operation, the system can allocate flow control credits for a first virtual channel to an upstream node in the distributed computing environment. The system can receive, via a message path comprising the upstream node, a message on the first virtual channel based on the allocated flow control credits. The system can then store the message in a queue associated with an input port and determine whether the message is a candidate for changing the first virtual channel at the node based on a mapping rule associated with the input port. If the message is a candidate, the system can associate the message with a second virtual channel indicated in the mapping rule in the queue. Subsequently, the system can send the message from the queue on the second virtual channel.

Abstract: Techniques of time-sensitive data delivery in distributed computing systems are disclosed herein. In one example, a server can disseminate the same information to multiple endpoints in a distributed computing system by transmitting multiple packets to the multiple endpoints hosted on additional servers in the distributed computing system. The multiple packets individually include a header field containing a delivery time before which the packets are not forwarded to corresponding final destinations and a payload containing data representing copies of information identical to one another destined to the multiple endpoints hosted on the additional servers.

Abstract: A traffic shaping circuit regulates packets transferred by a transmission resource into a network (e.g., a network on a chip) on behalf of a client. The packet transfers are selectively enabled or disabled based on a current budget value. The budget value is modified based on a packet-transfer cost in response to transferring a packet into the network. The rate of packet transfers into the network is monitored. A cost-adjustment signal is generated based on the rate of packet transfers. The packet-transfer cost is modified in response to the cost-adjustment signal for accounting for a subsequent-packet transfer into the network. The cost-adjustment signal may indicate an increase or decrease of the packet-transfer cost and/or a budget limit, both of which are read from a cost table comprising records ordered based on respective packet-transfer cost values. The packet-transfer cost and/or a budget limit are configurable.

Abstract: In a method for managing a VPN, a routing device establishes a BMP session with a BMP server. The routing device allocates a VPN label associated with a VPN instance, wherein the VPN instance is used for communication between the routing device and another routing device. Then, the routing device sends, to the BMP server, a BMP message that carries the VPN label. Because the routing device sends the VPN label through the BMP message, the routing device does not need to establish a BGP peer relationship with the BMP server to send the VPN label.

Abstract: Approaches, techniques, and mechanisms are disclosed for improving operations of a network switching device and/or network-at-large by utilizing queue delay as a basis for measuring congestion for the purposes of Automated Queue Management (“AQM”) and/or other congestion-based policies. Queue delay is an exact or approximate measure of the amount of time a data unit waits at a network device as a consequence of queuing, such as the amount of time the data unit spends in an egress queue while the data unit is being buffered by a traffic manager. Queue delay may be used as a substitute for queue size in existing AQM, Weighted Random Early Detection (“WRED”), Tail Drop, Explicit Congestion Notification (“ECN”), reflection, and/or other congestion management or notification algorithms. Or, a congestion score calculated based on the queue delay and one or more other metrics, such as queue size, may be used as a substitute.

Abstract: Systems and methods provide congruent bidirectional Segment Routing (SR) tunnels, namely congruent and fate-shared traffic forwarding for bidirectional SR tunnels. A bidirectional SR tunnel, as described herein, includes two unidirectional SR tunnels where the forward and reverse traffic directions follow the same path through the network when forwarded based on prefix and adjacency Segment Identifiers (SIDs). The term “congruent” is used herein to refer to the fact that the two unidirectional SR tunnels, i.e., the forward and reverse traffic directions, follow the same path through the network but in opposite directions. The guarantee of congruency is based on modification of the Segment Identifier (SID) configuration at the source nodes of each tunnel. Accordingly, the present disclosure maintains compatibility with existing Segment Routing configurations with the modifications solely at the source nodes.
