  • Patent number: 11411863
    Abstract: Metadata may be embedded in a service chain header (SCH) appended to a packet that is forwarded over a service chain path. The metadata may include information that is used to process the packet at a downstream service function chain (SFC) entity on the service chain path. The metadata TLV field may identify a service action to be performed by a downstream SFC entity. For example, the metadata TLV field may instruct the downstream SFC entity to drop the packet, to redirect the packet (or a traffic flow associated with the packet), to mirror a traffic flow, to terminate a communication connection, to start or stop a packet accounting, and/or to apply a higher grade of service. Alternatively, the metadata TLV field specifies an OAM service action list that identifies service actions that have been performed on the packet.

As such, the advantages of both formats can be combined with suitable design complexity and implementation. In an embodiment, data is arranged in a sequence of rows and stored in a first storage format at the primary database. The data arranged in the sequence of rows is also stored in a second storage format at the replica database. The sequence of rows is determined according to the first storage format or the second storage format. The first storage format is a row store (RS) and the second storage format is a column store (CS), or vice versa. In an embodiment, the sequence of rows is determined to improve compression efficiency at the CS.

  • Patent number: 11405283
    Abstract: Disclosed herein are various embodiments for constructing an abstract domain topology. In one embodiment, a Path Computation Element (PCE) is configured as a parent PCE to at least one child PCE. Each of the child PCEs is responsible for providing path computational services for a domain. Communication is established between the parent PCE and the at least one child PCE. The parent PCE receives from each of its child PCEs domain connection information corresponding to the domain of each child PCE. The parent PCE builds and maintains an abstract domain topology based on the domain connection information that it receives from its child PCEs. In one embodiment, the domain connection information is communicated from the child PCE to the parent PCE by adding a new notification-type (NT) and notification-value (NV) to a notification object in a Path Computation Element Communication Protocol (PCEP) notification message.

  • Patent number: 11362959
    Abstract: Latency Based Forwarding (LBF) techniques are presented for the management of the latencies, or delays, of packets forwarded over nodes, such as routers, of a network. In addition to a network header indicating a destination node for receiving the packet, a packet also includes an LBF header indicating the packets accumulated delay since leaving the sender, a maximum latency for the entire journey from the sender to the receiver and a minimum latency for the entire journey from the sender to the receiver. When a packet is received at a node, based on the accumulated delay, the maximum latency, and the minimum latency, the node places the packet in a forwarding queue to manage the delays between the sender and the receiver. The LBF can also indicate a policy for the forwarding node to used when determining the enqueueing of the packet.

  • Patent number: 11336347
    Abstract: Embodiments of this disclosure provide techniques for determining a device's beam correspondence status. As used herein, a device is considered to have “beam correspondence” when the device's TX and RX antennas satisfy a calibration criteria. In one example, a device's TX and RX antennas satisfy the calibration criteria when a difference between quality parameters corresponding to reference signals transmitted and received using corresponding TX and RX beams is less than a threshold. In another example, a device's TX and RX antennas satisfy the calibration criteria when a list of indices ranking the device's TX beams matches a list of indices ranking the device's RX beams. The lists of indices may be derived by transmitting and receiving references signals according to the devices RX and TX beams, and then generating list of indices based on quality parameters of the respective RX and TX beams.

  • Patent number: 11334355
    Abstract: Technology for providing data to a processing unit is disclosed. A computer processor may be divided into a master processing unit and consumer processing units. The master processing unit at least partially decodes a machine instruction and determines whether data is needed to execute the machine instruction. The master processing unit sends a request to memory for the data. The request may indicate that the data is to be sent from the memory to a consumer processing unit. The data sent by the memory in response to the request may be stored in local read storage that is close to the consumer processing unit for fast access. The master processing unit may also provide the machine instruction to the consumer processing unit. The consumer processing unit may access the data from the local read storage and execute the machine instruction based on the accessed data.

The UE is configured to be a synchronization source and transmit a first device-to-device synchronization signal (D2DSS) by using a synchronization resource that comprises a time resource, a frequency resource or a time and frequency resource. The base station instructs the first UE to transmit the first D2DSS using the synchronization resource. The base station signals the UE to configure the UE separately from the signal to transmit the D2DSS, and both of the signals are performed with radio resource control signaling from the base station to the UE.
