Abstract: A communication method includes: A transmit end device receives a first packet from a receive end device via a router, where the first packet includes a first field that indicates signal strength of the receive end device, and further includes a second field that indicates signal strength of the router. The transmit end device determines a distance between the receive end device and the router based on the first field, determines a distance between the router and the transmit end device based on the second field, and establishes a signaling connection to the receive end device through a local area network when the foregoing two distances meet a specific condition. In this way, a success rate of establishing a signaling connection by an electronic device through a local area network can be ensured as much as possible.

Abstract: A first switch port receives a first control packet, a header having a source media access control (MAC) address of a first MAC of a first interface of a sending device and a payload containing a second MAC of a second interface of the same sending device. The first and second interfaces form a bonded interface for failover purposes on the sending device. A second switch port receives a second control packet, a header having the second MAC as its source MAC and a payload containing the first MAC. The switch associates the first and second MAC addresses as related MAC addresses associated with the bonded interface. The switch facilitates failover between the secure interfaces via multiple uplinks while maintaining the port security on the switch by allowing transmission of data from either the first or second MAC address, associated as related MAC addresses, without triggering a port security violation.

Abstract: Examples described herein relate to a method for creating and managing a plurality of Multiple Basic Service Set Identifier (MBSSID) groups. The method may include configuring the MBSSID groups by setting a Maximum BSSID indicator to a value such that each of the plurality of MBSSID groups is allowed to utilize VAP slots up to a VAP capacity of the AP so long as the VAP capacity of the AP is not fully exhausted. Accordingly, when a request to create a VAP in a given MBSSID group is received, and the VAP capacity of the AP is not fully exhausted, the AP may create the VAP at any available VAP slot. The VAP is created such that a BSSID of the VAP is determined based on the Maximum BSSID indicator and a BSSID index relative to a transmit VAP of the given MBSSID group.

Abstract: Systems are methods are provided for implementing load balancing of IPsec security associations (SAs) SAs between different heterogeneous cores, for example in a multiple controller systems. The balancing of IPsec SAs are performed using software implementations of IPsec offloading and/or hardware implementations of IPsec offloading. By balancing the processing functions related to orchestration of IPsec SAs between hardware (e.g., IPsec hardware accelerator) and software (e.g., IPsec software accelerator), the methods realize increased optimization, improved user experience, and enhanced product performance in networks using IPsec. For example, an IPsec session is initiated, and it is determined whether a resource limitation for a hardware-based IPsec accelerator has been reached. If the limitation for the hardware-based IPsec accelerator has been reached, processing for the IPsec SA for the initiated IPsec session is offloaded to a software-based IPsec accelerator.

Abstract: Example implementations relate to connecting an IoT device to a wireless network using Device Provisioning Protocol (DPP). An authentication server receives a DPP network access authorization request including a connector identifier from an Access Point (AP) in communication with the IoT device. The connector identifier is a hash of the public network access key of the IoT device. If the connector identifier is valid, the authentication server determines a configurable policy from a set of configurable policies that is applicable to the IoT device. The authentication server transmits network permissions defined in the configurable policy to the AP. The IoT device is connected to the wireless network by the AP based on the network permissions.
