Abstract: Some embodiments provide a novel way to insert a service (e.g., a third party service) in the path of a data message flow, between two machines (e.g., two VMs, two containers, etc.) in a public cloud environment. For a particular tenant of the public cloud, some embodiments create an overlay logical network with a logical overlay address space. To perform a service on data messages of a flow between two machines, the logical overlay network passes to the public cloud's underlay network the data messages with their destination address (e.g., destination IP addresses) defined in the logical overlay network. The underlay network (e.g., an underlay default downlink gateway) is configured to pass data messages with such destination addresses (e.g., with logical overlay destination addresses) to a set of one or more service machines. The underlay network (e.g.

Abstract: The described technology is generally directed towards adaptively selecting a repetition level in wireless communications, based on events to improve coverage range via the repetition level while not unnecessarily reducing throughput. One such event can include a current signal-to-noise-ratio, e.g., as reported in a channel quality indicator report from a user equipment. Another such event can comprise a number of consecutive hybrid automatic repeat request acknowledgments or negative acknowledgments (HARQ ACKS/NACKS), in which consecutive ACKs tend to indicate good signal quality, while consecutive NACKs tend to indicate poor signal quality. A combination of channel quality indicator-based adaptive repetition level and HARQ ACK/NACK-based adaptive repetition level can be employed.

Abstract: A first communication device generates a first portion and a second portion of a wakeup radio (WUR) wakeup packet. The first portion of the WUR wakeup packet corresponds to a wireless local area network (WLAN) legacy preamble, and spans a first frequency bandwidth. The second portion of the WUR wakeup packet spans a second bandwidth that is less than the first bandwidth, and is configured to cause a WUR of a second communication device to cause a WLAN network interface device of the second communication device to transition from a low power state to the active state. Generating the second portion of the WUR wakeup packet includes i) generating a sync portion having a plurality of sync symbols, and ii) generating a wakeup packet body. The first communication device transmits the WUR wakeup packet.

Abstract: An emulation mode for network devices is described as a means of isolating a defective network device from real network traffic, while continuing to transmit faux traffic to the defective network device, wherein the faux traffic is intentionally dropped. The emulation mode allows the defective network device to be tested in an environment that appears real, without impacting user traffic. A management server can control one or more neighbor network devices and place them in the emulation mode as a way to isolate and test the defective network device. In the emulation mode, the neighbor network device monitors for packets that, based on previous routing history, would be sent to the defective network device and, instead, routes them to functioning network devices using a current FIB. A virtual RIB/FIB can also be used to route the same packets to the defective network device.

The network device provides, to the user device, an attach accept, that includes the rules, to permit the user device is to connect with the network and to utilize the rules.

Abstract: A computer-implemented method for communicating data between computer systems in the functions of a source computer system and of a target computer system is performed by a data modification engine in a gateway computer that is communicatively connected between the computer systems. The engine receives an original data package from the source computer system with elements that are arranged according to a pre-defined data-structure. The engine accesses a rule template that corresponds to the data-structure and that provides a plurality of pre-defined rules. The engine separates the original data package into elements, processes the elements by digitally transforming them according to the rules, combines them to a modified data package and sends the modified data package to the target computer system.

Abstract: A first communication device generates a media access control (MAC) frame that includes an indication of a change in a block acknowledgment (BA) session that was previously established between the first communication device and a second communication device. The first communication device transmits the MAC frame to the second communication device. The MAC frame is configured to cause the second communication device to adopt the change in the BA session in response to receiving the MAC frame.

Abstract: A first device determines whether an indicator is configured to allow use of an increased value for an information unit pacing credit that is greater than a default value for the information unit pacing credit, where the information unit pacing credit indicates a number of information units that a second device is allowed to send to the first device without waiting for any additional response from the first device. In response to determining that the indicator is configured to allow use of the increased value for the information unit pacing credit that is greater than the default value for the information unit pacing credit, the first device adjusts the information unit pacing credit via a response sent from the first device to the second device, to the increased value that is greater than the default value.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may establish a configuration for at least one carrier based on multiple transmission time interval (TTI) lengths. Several TTI lengths may be associated in a TTI group, and aspects of the configuration may be the same for all TTIs having a TTI length in the TTI group. The device may then communicate using the carrier configuration based on the TTI group. In some cases, a second TTI group with different TTI lengths from the first group may also be identified, and the device may communicate using TTI from the second group using a different TTI group configuration. Aspects of a TTI group configuration may include a common control channel format, resource allocation granularity, hybrid automatic repeat request (HARQ) process, HARQ timing, soft buffer size, channel state information (CSI) reporting configuration, or an uplink control channel.
