Abstract: The present disclosure describes a networking switch of a network and method for operating the networking switch. The networking switch communicates within the network using datagrams, such as packets and/or frames. The frames include packets of a first communication protocol or layer having headers of the first communication protocol or layer. In some situations, the packets of the first communication protocol or layer are embedded with packets of a second communication protocol or layer. Often times, one or more fields of headers of the first communication protocol or layer convey substantially similar or redundant information, such as routing information to provide an example, as one or more fields of headers of the second communication protocol or layer. In these situations, the networking switch can compress the one or more fields of the headers of the first communication protocol or layer

Abstract: A system and method for limited the processing of interrupt-causing messages within a communication device. A user is able to set various values for dictating the bounds of a leaky bucket processor. The leaky bucket maintains and monitors a count, and dictates whether message processing is permitted or prohibited based on the count. When a message is processed, the count is decremented. When a predetermined time passes without processing a message, the count is incremented. If the count ever reaches a predetermined low threshold value, message processing is prohibited for a predetermined time On the other hand, if the count returns to a predetermined high threshold value, processing is permitted.

The at least one processor circuit may be configured to identify that a packet is scheduled to be received by a receiver and retrieve at least one transmission indicator that indicates whether at least one transmitter is transmitting, where the at least one transmitter is collocated with the receiver within a device. The at least one processor circuit may be further configured to select a first gain table for reception of the packet by the receiver when the at least one transmission indicator indicates that the at least one transmitter is transmitting, otherwise selecting a second gain table for reception of the packet by the receiver. The at least one processor circuit may be further configured to apply gain to the receiver based at least on the selected gain table.

Abstract: A near field communications (NFC) device is disclosed that is capable of optimizing a gain for received signals. Measurements are made of signals received from an NFC environment and are compared to one or more threshold hold values. Based on the comparison, it is determined whether the measurements indicate underamplification or overamplification. Depending on the results of the analysis, one or more components within the NFC device is adjusted to increase or decrease the gain, respectively. The measurements may be taken during an unloaded baseline state or during loading, and may be compared to previous measurements to estimate their accuracy.

Abstract: A wireless communication device (alternatively, device) includes a processing circuitry configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. A device communicates with other devices informing them of energy, power, etc. management operation (e.g., with respect to low power or sleep mode). When the device receives responses from each of the other devices that they are informed of the operation of the device, then device performs such energy, power, etc. management. Alternatively, when response(s) are not received from all of the other devices, the device performs such energy, power, etc. management after a period of time (e.g., number of beacon intervals (BIs)).
