  • Patent number: 11129036
    Abstract: Methods and apparatuses estimating pathloss of PUSCH in a wireless communication system are disclosed herein. In one method, the UE receives a first configuration of a first serving cell and a second serving cell, wherein the second serving cell is a pathloss reference for the first serving cell. The UE receives a second configuration of multiple downlink bandwidth parts of the second serving cell, wherein a downlink bandwidth part among the multiple downlink bandwidth parts is an active downlink bandwidth part. The UE estimates (or derives) a pathloss for an uplink transmission in an uplink bandwidth part of the first serving cell based on a reference signal in the downlink bandwidth part.

  • Patent number: 11106562
    Abstract: A system and method for detecting anomalies in task workflows uses a directed acyclic graph constructed using metrics for a workflow of a task collected from software entities that perform operations to execute the task. A feature signature of the task workflow is generated using key values extracted from the directed acyclic graph, which is then used to compute a similarity value by comparing the feature signature with a reference feature signature for a baseline task workflow. The similarity value is then used to diagnose any performance issues in the workflow of the task executed by the software entities.

  • Patent number: 11032249
    Abstract: A server in a captive portal accepts a connection from a user device to the IP address of the server and receives a HTTP or HTTPS request over the connection. The connection may be a result of the user device being previously determined to be not logged in, and consequently provided the IP address of the server as a DNS resolved IP address, the user device thereafter caching the IP address of the server. The server responds with requested content if the target host of the request is a local host. If the target host is a remote destination, the server queries a login database to determine whether the user device is logged in. The server acts as a transparent proxy between the user device and the remote destination if the user device is logged in, else the server sends alternate content to the user device over the connection.

  • Patent number: 10742555
    Abstract: A method and corresponding apparatus for detecting network congestion. The method includes capturing, using a local clock of a sender device, a send time of an outgoing packet sent from the sender device to a receiver device through a forward route, and capturing, using the local clock of the sender device, a receive time of an acknowledgment packet sent from the receiver device to the sender device through a backward route. The acknowledgment packet contains timing information, generated using a local clock of the receiver device, for determining an internal latency of the receiver device. A round trip time is computed as a difference between the send time and the receive time. The internal latency is subtracted from the round trip time to compute a total propagation time. If the total propagation time is above a threshold, the forward route and the backward route are changed.

  • Patent number: 10721034
    Abstract: In a cable network, embodiments detect and remediate a non-responsive customer premise equipment (CPE) device in a customer's premise with minimal or no interaction with a customer. Embodiments may detect and remediate a non-responsive CPE device without rebooting the non-responsive CPE device or the associated cable modem. Embodiments include troubleshooting a data link layer (e.g., Open System Interconnection (OSI) layer 2, or media access control (MAC) layer) and a network layer (e.g., OSI layer 3, or Internet layer) between a service operator network and the non-responsive CPE device. Embodiments include a guided integration and a proactive integration method, computer program product, and system to reduce and/or eliminate the need for a customer service representative to reboot a cable modem, and/or for a customer to reboot a non-responsive CPE device resulting in a fast and less disruptive service experience for the customer.

  • Patent number: 10715205
    Abstract: A method and a testing device for determining signal-to-noise headroom of a pair of conductors are provided. In the method and testing device, a gain of electric signal transmissions over a pair of conductors is varied to reach a first gain. Prior to reaching the first gain a transition between reception failure and successful reception of the electric signal transmissions does not occur. A first electric signal having the first gain is transmitted over a first end of the pair of conductors and it is determined that the transition between reception failure and successful reception of the first electric signal occurred. A signal-to-noise ratio (SNR) headroom for the pair of conductors is determined based on the first gain at which the transition between reception failure and successful reception occurred.

  • Patent number: 10693809
    Abstract: System and method for representing performance management agent (PMA) attributes as subnet management agent (SMA) attributes in a high performance computing environment. In general legacy systems, performance metrics, as collected by a performance management agent, can only be collected via the use of general data packets traversing a subnet. In accordance with an embodiment, by configuring a SMA attribute to comprise the same performance metrics as collected by a PMA, a subnet manager, or another management component, can access the performance metrics in-band via the use of a subnet management packet.

  • Patent number: 10673718
    Abstract: Disclosed herein are systems, methods, and apparatus for performing a new kind of traceroute. This traceroute is referred to herein as a “reverse” traceroute, as it enables a given network node to determine the path of packets sent to it from another node. Preferably, an encapsulating tunnel between the two nodes is leveraged. Preferably, a given network node (“first node”) performs the reverse traceroute by sending encapsulated inner packets in the tunnel to another network node (“second node”). The second node reflects the inner packets back to the first node. Preferably, the inner packets are configured such that their IP header TTLs expire at intermediate nodes (such as routers), and such that the resulting error messages are reported to the first node. In this way, the first node obtains information about the topology of the network and the path taken by inbound packets.

  • Patent number: 10601688
    Abstract: A method and apparatus are provided for detecting a fault condition in a network, making use of standard parameter data generated by a network termination device of a user of the network, the method comprising, in a training phase, the remote retrieval of selected parameters from a predetermined set of users' network termination devices in order to generate one or more representative models of expected operational status using the retrieved parameters and, in a monitoring phase, determining a measure of operational status for the set of users at some future time and comparing that with a corresponding expected model measure. Parameter retrieval takes place over substantially the same path through the network as used to supply services to a respective network termination device so that the models are generated in respect of communications over those elements of network infrastructure likely to affect operational status of the respective set of users in the event of a fault condition.
