Abstract: One embodiment performs longest prefix matching operations in one or more different manners that provides packet processing and/or memory efficiencies in the processing of packets. In one embodiment, a packet switching device determines a set of one or more mask lengths of a particular conforming entry of a multibit trie or other data structure that matches a particular address of a packet via a lookup operation in a mask length data structure. A conforming entry refers to an entry which has less than or equal to a maximum number of different prefix lengths, with this maximum number corresponding to the maximum number of prefix lengths which can be searched in parallel in the address space for a longest matching prefix by the implementing hardware. The packet switching device then performs corresponding hash table lookup operation(s) in parallel in determining an overall longest matching prefix for the particular address.

Abstract: In an example, a system is described which includes a centralized controller, a first agent controller, and a second agent controller. The centralized controller executes a routing application to control routing of network traffic across links of a wide area network. The first agent controller is deployed at a branch location of the wide area network to notify the routing application when a host at the branch location requests membership in a multicast group. The second agent controller is deployed at a headend of the wide area network to modify a forwarding rule in response to an instruction from the routing application. The forwarding rule controls an interaction between the headend location and an upstream router to redirect network traffic associated with the multicast group in a manner that joins the host to the multicast group.

Abstract: Systems and methods for supporting inter subnet partitions in a high performance computing environment. In accordance with an embodiment, a fabric manager can define a range of P_Key values, among a plurality of P_Key values, as a inter subnet partition (ISP) P_Key range. The fabric manager can communicate this defined range of P_Key values to a number of subnets, via their subnet managers. The subnet managers in each subnet retain management over their subnets. As there is no central management that configures each side of inter subnet communication, subnet managers on within participating subnets can set up ISP membership, and then exchange information with the other subnet.

Abstract: A mobile device, wireless network and their method of operation provide suggestion of corrective actions of the network based on performance evaluation of communications between a connected mobile device and the communications network. The communications network tracks location of mobile devices and stores performance data of connections between the mobile devices and the network. The performance data is referenced to expected performance data to determine whether a fault exists and a corrective action is suggested when the fault exists. Access to the location information by another computer is controlled by a preference flag set in response to a communication from the mobile device.

Abstract: In one embodiment, a labeling service receives traffic feature data for a cluster of endpoint devices in a network. A device classification service forms the cluster of endpoint devices by applying machine learning-based clustering to the feature data. The labeling service selects a subset of the endpoint devices in the cluster, in an effort to maximize diversity of the traffic feature data of the selected endpoint devices. The labeling service sends a control command into the network, to trigger a traffic behavior by the selected subset. The labeling service receives updated traffic feature data for the selected subset associated with the triggered traffic behavior. The labeling service controls whether a label request is sent to a user interface for labeling of the cluster of endpoint devices with a device type, based on the updated traffic feature data for the subset of endpoint devices in the cluster.

The UE-initiated HO procedure may include a PUSH mechanism in handoff. Alternatively, the UE-initiated handoff procedure comprises a PULL mechanism in handoff.

Abstract: Establishment of integrated links comprising integrated wireless backhaul communications links and access communications links is facilitated by transmitting multiplexed sync signals to enable synchronization between the relay transmission point devices, and using a random access channel procedure to complete the establishment. The integrated wireless backhaul communications links and access communications links can be maintained by measuring channel characteristics of the backhaul communications links using a measurement reference signal.

Abstract: Aspects of the present disclosure disclose techniques for implementing a wideband reference signal to improve the narrowband channel estimation performance associated with narrowband demodulation reference signal (DMRS) for the data channel in NR communications. Specifically, because the wideband reference signal may occupy wider bandwidth than the DMRS, the channel estimation realized may be more accurate than solely relying on the narrowband DMRS. In some examples, the wideband reference signal, which may be control reference signals (CRS), channel state information (CSI) reference signal (CSI-RS) in downlink or uplink sounding reference signal (SRS), may be associated with a corresponding narrowband DMRS in a data channel. The wideband reference signal may be either included in the control channel region or the data channel region.

Abstract: Described herein are systems, methods, and software to enhance secure communications between computing systems. In one implementation, a communication service identifies a communication request from an application on the computing system to transfer data to a second application on a second computing system. In response to the communication request, the communication service identifies a communication group of a plurality of communication groups associated with the application and the second application. Once the communication group is identified, the communication service identifies a communication quality of service based on the identified communication group, and transfers the data associated with the communication request to the second computing system in accordance with the communication quality of service.

Abstract: Improved network event tagging for mobile communications is described herein. By way of example, a mobile network can be configured to take periodic geographic positions of a mobile terminal operating within the mobile network. Network events occurring between the periodic geographic positions, otherwise partially unknown in position, can be estimated by referencing topographical information and estimating a route of travel of the mobile device. Estimated speed of the mobile device can be utilized to place the mobile device on a road network, cycling route, pedestrian walkway, or the like, and refine the estimated position of the mobile device at the time of the network event. Such estimates can be refined from traffic information or other real-time travel data. An estimated position of the mobile device can be output as an approximation of the network event to facilitate event modeling for the mobile network.
