  • Patent number: 11910360
    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may utilize opportunistic cooperative relaying to support exchanging packets between UEs without establishing or maintaining beamforming alignment between the UEs. Specifically, a source UE may invite nearby UEs (e.g., helper UEs) that receive a sidelink transmission (e.g., a packet meant for a different destination UE) to perform a single frequency network (SFN)-type transmission to opportunistically relay the packet to the destination UE. The helper UEs may receive, decode, and transmit the sidelink signaling from the source UE without establishing or configuring a relay agreement with the source UE. The destination UE may receive the sidelink signaling via cascading, SFN-type transmissions by one or more helper UEs. The destination UE may respond to the sidelink signaling with feedback information via one or more helper UEs or directly to the source UE.

  • Patent number: 11876852
    Abstract: Described embodiments provide for dynamically optimizing the number of application layer streams that may be multiplexed into a single transport layer connection, providing the advantages of application layer multiplexing without incurring unnecessary congestion-based network delays. A device may monitor net bandwidth and packet loss rates for a connection, and may dynamically increase and decrease a number of concurrent application layer streams to balance throughput and congestion avoidance. As congestion increases, the device may reduce concurrent stream limits in order to spawn additional transport layer connections, allowing faster congestion recovery and reduced performance impairment.

  • Patent number: 11871238
    Abstract: Described herein are systems and methods to improve multicast network performance by improving bootstrap message (BSM) in a bootstrap router (BSR). After BSR election, all candidate Rendezvous Points (C-RPs) send their group-to-RP mapping information to the elected BSR (E-BSR). The E-BSR collects the group-to-RP information from C-RPs and forms bootstrap message (BSM) comprising information of a RP set. A global flag and one or more group flags are incorporated into the BSM to indicate whether the BSM has changed since last transmission and which part of the BSM has changed. The length of the BSM to be transmitted may be dynamically determined. Upon receiving the BSM, each multicast router may operate according to the flags embedded in the BSM. Therefore, the processing process for the BSM at multicast router side may be simplified.

  • Patent number: 11665092
    Abstract: Some embodiments provide a method that generates different network measurements data (e.g., network topology, bandwidth estimation of different paths, etc.) for a pair of endpoints upon receiving a network administrative request (e.g., an application programming interface (API) request) or by other means (e.g., automatically and without intervention of a user). In some embodiments, the method is implemented by a network measurement agent operating on each endpoint and a centralized service component (e.g., web service layer) executing on a network manager machine (e.g., a controller) that responds to measurement requests. The network measurement agent probes the network periodically (i.e., in certain time intervals) or upon an API request that it receives through the network manager machine to gather the measurement data of a particular network topology between a pair of endpoints.

  • Patent number: 11665091
    Abstract: Apparatuses and methods are provided in which a CE protocol communication session is established, at a first provider edge network device (PE), for customer equipment device (CE) multi-homed to the first PE and one or more second PEs. The first PE is an owner of the CE protocol communication session. The first PE signals to the one or more second PEs an ownership message indicating that the first PE is the owner of the CE protocol communication session. The ownership message includes parameters that enable one or more second PEs to install in their respective forwarding tables a redirect policy to instruct the respective PE to forward packets of this session to the first PE via an overlay segment. The first PE receives the packets of the session via the overlay segment based on the ownership message.

  • Patent number: 11627091
    Abstract: Virtual application and desktop delivery may be optimized by supplying application metadata and user intent to the device between a client and a server hosting resources for the delivery. The data packets used to deliver the virtual application or desktop may be also tagged with references to the application. By supplying the metadata and tagging packets with the metadata, an intermediary network device may provide streams of data packets at the target QoS. In addition, the device may apply network resource allocation rules (e.g., firewalls and QoS configuration) for redirected content retrieved by the client out of band relative to a virtual channel such as the Internet. The network resource allocation rules may differ for different types of resources accessed. The device may also control a delivery agent on the server to modify communication sessions established through the virtual channels based on network conditions.

  • Patent number: 11622135
    Abstract: Techniques for allocating bandwidth for low latency content and buffered content are described. In accordance with various embodiments, a bandwidth allocation method is performed at a device (e.g., a server) with one or more processors and a non-transitory memory. The server determines available bandwidth for delivering content to a client device in a stream, where the stream includes low latency content and buffered content. The server further identifies characteristics of the low latency content. The server then allocates a first portion of the available bandwidth to the low latency content and a second portion of the available bandwidth to the buffered content based on the characteristics of the low latency content.

  • Patent number: 11588663
    Abstract: A Controller Area Network (CAN) transceiver determines a voltage differential signal from analog signaling and provides a digital output signal at a receiver output to a CAN controller based on the voltage differential signal. The analog signaling received from the CAN bus can operate with a first voltage level scheme of a first CAN protocol and a second voltage level scheme for a second CAN protocol. A first comparator compares the voltage differential signal to a first threshold which is set to a value which differentiates between a logic low bit and logic high bit in accordance with the second CAN protocol. Filtering circuitry selectively filters an output of the first comparator based on detection of noise on the CAN bus to provide a first digital signal indicative of activity on the CAN bus according to the second CAN protocol.

  • Patent number: 11561823
    Abstract: In general, the disclosure describes techniques for lockless management of immutable objects by multi-threaded processes. A device comprising a processor may implement the techniques, where the processor execute a multi-threaded process including a producer thread and a consumer thread. The producer thread may instantiate an immutable object, and provide, to the consumer thread, a reference to the immutable object. The producer thread may also increment a reference counter to indicate that the reference has been provided to the consumer thread, where the reference counter is local to the producer thread and inaccessible to the at least two consumer threads. The producer thread may receive, from the consumer thread, a notification that the consumer thread has finished processing the immutable object, and decrement, responsive to receiving the notification, the reference counter. The producer thread may then delete, based on the reference counter, the immutable object.

  • Patent number: 11563692
    Abstract: A communications method enables a path computation element (PCE) to notify path computation clients (PCCs) about the shared resources of independent label switch paths by allowing a PCE to send an association object with a new association type to PCC. A PCE Communication Protocol extension that associates label-switched paths (LSPs) whose ingress, or egress, or both ingress and egress are different for resource sharing to avoid path computation failures or duplicate allocation of resources during common links for new LSPs created during an update of end-to-end (E2E) LSP. The PCC employs Resource Reservation Protocol (RSVP) for LSP signalling, PCC forwards path message information along with association object to the RSVP for LSP signalling. The RSVP uses the association object in its reservation message for LSP setup.
