摘要： A wireless device can achieve higher predictability for its transmissions by inserting a placeholder frame in a transmission queue before time sensitive data has been received. In addition, a contention countdown associated with the placeholder frame can start before the time sensitive data is ready for transmission. Once the data is available, the device can insert the data into the payload of the placeholder frame, thereby reducing the wait time before the data can be transmitted wirelessly. Additionally, the device can improve reliability by transmitting data using multiple subcarrier RUs in a channel. The data blocks and the duplicative data can be transmitted in parallel using the subcarrier RUs. If a subset of the subcarrier RUs are blocked because of narrowband interference, the receiving device can nonetheless recover the data blocks and reconstruct the packet from the data transported on the RUs that did not have interference.

摘要： Embodiments herein describe techniques for testing optical components in a photonic chip using a testing structure disposed in a sacrificial region of a wafer. In one embodiment, the wafer is processed to form multiple photonic chips integrated into the wafer. While forming optical components in the photonic chips (e.g., modulators, detectors, waveguides, etc.), a testing structure can be formed in one or more sacrificial regions in the wafer. In one embodiment, the testing structure is arranged near an edge coupler in the photonic chip such that an optical signal can be transferred between the photonic chip and the testing structure. Moreover, the testing structure has a grating coupler disposed at or near a top surface of the wafer which permits optical signals to be transmitted into, or received from, the grating coupler when an optical probe is arranged above the grating coupler.

摘要： A method to operate a core network element, such as a Session Management Function (SMF) of a 5G core architecture. The method includes establishing a session between a user equipment and a core network element, determining, on the core network element, an activity pattern for the session, and based on the activity pattern, one of maintaining context information for the session in cache memory of the core network element and off-loading the context information for the session from the cache memory of the core network element to a database that is different from the cache memory.

摘要： Techniques for routing Internet Protocol security (IPsec) data packets. An index is assigned to a Security Parameter Index (SPI) header of the IPsec data packet. The index includes information for routing the data packet to a particular Encapsulating Security Payload (ESP) processor. The data packet can be routed using techniques that are analogous to conventional routing protocols such as IPv4 routing protocol. This allows the data packet to be routed using less expensive routing protocols rather than relying solely on more expensive load balancing techniques to route the data packet. This also advantageously allows the data packet to be routed employing routing techniques developed over decades of routing protocol development.

摘要： The disclosed technology relates to determining a period in which a network is busier relative to other periods. The method may comprise analyzing network utilization data from a network segment of the network. The network utilization data may be collected over a first duration. The method may further comprise of determining, from the network utilization data, a baseline network utilization. The baseline network utilization may be a persistent quantification of network utilization present throughout the first duration. The method may further comprise identifying at least a reoccurring period that is characterized by network utilization data indicating consecutive network utilization that is above the baseline network utilizations; and configuring a network controller to designate the at least the reoccurring period as a busy period.

摘要： Disclosed are systems, apparatuses, methods, and computer-readable media for configuring network groups without software-based processing and management. A method includes: transmitting a topology request from a first leaf node to a first spine node; in response to receiving a network topology reply from a second leaf node, generating a network topology identifying a group of leaf nodes, the network topology reply including network information associated with the second leaf node, and in response to a request to send a message from a first network node connected to the first leaf node to a second network node connected to the second leaf node, transmitting the message to the second leaf node based on the network information from the network topology reply. In some aspects, the first spine node or a second spine node are configured to receive the message and transmit the message to the second leaf node.

摘要： Techniques are provided to inform a mobile packet core of the access network/radio access technology (AN/RAT) change with the use of in-band signaling along the user plane and hence reduce signaling between radio access network and mobile packet core network. A new extension header content is defined to signal the AN/RAT change information, Cell Group changes and acknowledging the same. Further still, a method is provided to handle AN change notification for split bearer scenarios by introducing a split bearer flag for the mobile packet core to be notified of the predominant access type serving the subscriber data session in 5G Non-Stand Alone (NSA) Option-3, Option-3A and Option-3X, so that static or dynamic configurations can be applied by the mobile core network accordingly.

摘要： Energy savings through adjustment of link speed may be provided. A utilization of a port may be monitored. The port may be configured to run at a plurality of speeds. Based on monitoring the utilization of the port, it may be determined that the utilization of the port has dropped, for a first predetermined time period, below a supported speed lower than a current port speed. Energy consumed by the port may be lowered, in response to determining that the utilization of the port has dropped, for the first predetermined time period, below a supported speed lower than the current port speed. Lowering the energy consumed by the port may comprise re-configuring the port to run at a second speed comprising a supported speed below the current speed. When the utilization of the port exceeds a predefined threshold over a second predetermined time period, the port speed may be increased.
