An electronic device connects to another electronic device using a communication link, such as a Wi-Fi link as provided by a Wi-Fi access point. The electronic device includes a transport monitoring module that monitors outgoing communications (e.g., Transmission Control Protocol (TCP) packets) from the electronic device. When the other electronic device disconnects from the Wi-Fi access point, the transport monitoring module determines that a transport anomaly has occurred. In response to determining that the transport anomaly has occurred, a probe module of the electronic device sends a probe (e.g., an Internet Protocol Security (IPSec) dead peer detection probe) to determine whether the other electronic device is reachable.

Disclosed is a monitoring system, having: a keybox configured to store a key; a monitoring device, wherein via a monitoring device controller, the monitoring device is configured to: detect a first alert condition indicative of the keybox being outside a communication range of shortwave radio; and transmit a first alert to a remote implement that is indicative of an occurrence of the first alert condition.

Systems and methods for improving data transmission rates in communication networks are disclosed. In an 802.11 wireless communication network, where a source node of the wireless network transmits TCP data to a destination node of the wireless network, the destination node does not transmit TCP acknowledgments (ACKs) for the TCP data if 802.11 ACKs indicate that the destination node received the TCP data. If a source outside the wireless network transmits TCP data to the destination node within the wireless network through an intermediate device, such as an access point, the destination node suppresses transmitting TCP ACKs. The intermediate device transmits TCP ACKs as proxy for the destination node to the source. The intermediate device also suppresses TCP ACKs where a source node within the wireless network sends the TCP data to a destination node outside of the wireless network.

Method and apparatus for controlling migration of a Quick User Datagram Protocol (UDP) Internet Connections (QUIC) connection between a server and a neighboring server of a content delivery network (CDN). The server and the neighboring server comprise respective cache memories, are comprised in the CDN and have a same server IP-address. The QUIC connection is identifiable by a connection identifier (CID) and is established to a migrating wireless device having a client IP-address. The method for controlling migration of the QUIC connection comprises receiving static key information representative of the QUIC connection; determining context transfer state information for the QUIC connection; and controlling transmission of a stateless reset token for the QUIC connection based on the determined context transfer state.

Multi-level beam scheduling in a wireless communications circuit, particularly for a wireless communications system (WCS), is disclosed. The WCS includes a central unit(s) and a wireless communications circuit(s) configured to reduce beamforming overhead and improve radio frequency (RF) coverage in a wireless communications cell(s) based on a multi-level beam scheduling scheme. In a non-limiting example, the multi-level beam scheduling scheme includes a first level (L1) scheduler, a second level (L2) scheduler, and a third level (L3) scheduler configured to perform cross-cell beam scheduling, in-cell beam scheduling, and in-beam user equipment (UE) scheduling, respectively. By employing the multi-level beam scheduling scheme in the WCS, it may be possible to reduce processing overhead and improve resource usage, data throughput, and system adaptability of the wireless communications circuit(s), thus helping to optimize capacity and throughput in the wireless communications cell(s).
