  • Patent number: 10791018
    Abstract: A buffer box can be configured for an edge switch that is connected to one or more downstream nodes of a stateful stream processing system. Various upstream nodes can transmit data to downstream nodes for processing. At various locations in the data streams, the upstream nodes can include markers to indicate when a checkpoint should be generated or updated for the state of the data. Between markers, the data can be copied to a respective buffer box for the downstream node and edge switch. In the event the downstream node fails, the downstream node can obtain the checkpoint data to update state, and can receive the recent data from the local buffer box, rather than the corresponding upstream nodes. This can improve bandwidth usage and recovery time versus conventional recovery approaches, and can minimize impact of the recovery on other nodes across the network.

  • Patent number: 10743259
    Abstract: Wireless transition timers associated with wireless transition states are adaptively controlled in relation to use of applications by user equipment (UE). A UE can include a transition management component (TMC) that can adaptively control wireless transition timers associated with wireless states based on application type, session content, or other factors. The TMC monitors data flow associated with an application and, for a current or subsequent communication session, controls the length of wireless transition timers and switching between wireless states to improve UE, application, and/or network performance while maintaining QOE for the user. The TMC can access a timer look-up table that maps wireless transition timers to application type, content type, user behavior, or other factors. The TMC also can desirably control maintaining persistence or always-on connections by controlling switching between wireless states using the adapted wireless transition timers.

  • Patent number: 10708875
    Abstract: A half-duplex radio device (100) generates a repetitive transmission of an uplink message to a base station (150) of the cellular network. The radio device (100) splits the repetitive transmission of the uplink message into a sequence of multiple transmit periods and configures at least one measurement gap between the transmit periods. In the transmit periods, the radio device (100) sends the repetitive transmission to the base station. In the at least one measurement gap configured between the transmit periods, the radio device (100) temporarily switches to receiving at least one downlink signal from the base station (150). Based on the received at least one downlink signal, the radio device (100) estimates a frequency error of a reference frequency source of the radio device (100).

  • Patent number: 10694414
    Abstract: A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/receive unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQI feedback period based on the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU based on the uplink and downlink transmission needs and sends a command to the WTRU to change the CQI feedback period of the WTRU.

  • Patent number: 10693770
    Abstract: Techniques are described for providing session-aware, stateful network services to subscriber packet flows. Devices within a service provider network direct subscriber packets along service chains. Each tunnel is established to direct traffic according a particular ordered set of network services for the corresponding service chain. An ingress device for the tunnels encapsulate the subscriber packets and embed opaque session cookies that each uniquely identifies a collection of packet flows of a subscriber session amongst other packet flows transported by a given service tunnel. Each service node need only identify the tunnel on which a tunnel packet was received and the session cookie embedded within the tunnel packet to uniquely associate the encapsulated subscriber packet with a subscriber session, without needing to further inspect the encapsulated subscriber packet, and to index or otherwise retrieve state and statistics required to enforce the network service the service nod is programmed to deliver.

  • Patent number: 10673767
    Abstract: Conventional internet routing is handled using routing protocols such as the Border Gateway Protocol (BGP). However, simple BGP does not account for latency, packet loss, or cost. To address this problem, smart routing systems that route traffic fast and in a cost-effective manner are implemented. In one approach, smart routing systems measure, compare, and analyze round-trip latencies and other metrics between a customer premises and one or more endpoints. Optimal inbound and outbound transit providers are selected for each endpoint based on these measurements. Other smart routing systems collect and analyze Real User Monitoring (RUM) data to predict latency performance of different content origins for serving data to a particular client based on the client's IP address and the content origins' IP addresses, which are ranked by performance.
