Computing device and method for performing a secure neighbor discovery
Computing devices and method for performing a secure neighbor discovery. A local computing device transmits an encrypted local node identifier and an encrypted local challenge to a remote computing device. The remote computing device generates a local challenge response based on the local challenge; and transmits an encrypted remote node identifier and an encrypted local challenge response to the local computing device. The local computing device determines that the received local challenge response corresponds to an expected local challenge response generated based on the local challenge. The remote computing device further transmits an encrypted remote challenge. The local computing device generates a remote challenge response based on the remote challenge; and transmits an encrypted remote challenge response to the remote computing device. The remote computing device determines that the received remote challenge response corresponds to an expected remote challenge response generated based on the remote challenge.

System and method of applying policy based, targeted prefix advertisements via internet protocol version 6 (IPv6) stateless address auto-configuration (SLAAC) router advertisement (RA) poisoning
Systems and network devices configured to use Stateless Address Auto-Configuration (SLAAC) to provide different internet protocol (IP) address information to user equipment (UE) devices that are connected to the same local area network (LAN). A network device (e.g., default router, etc.) may determine whether a UE device is eligible to receive special treatment based on a link-layer address of the UE device. The network device send the UE device an unicast router advertisement that includes a special prefix in response to determining that the UE device is eligible to receive special treatment. The network device may send the UE device an unicast router advertisement that includes a base prefix for the LAN in response to determining that the UE device is not eligible to receive special treatment.
DISTRIBUTED AUTOMATIC MULTICAST ADDRESS ASSIGNMENT DEVICE AND METHOD
A solution is disclosed for providing automatic multicast address assignment and conflict resolution for AV streams multicast over a networked AV system. The solution includes a device for monitoring the system for messages associated with AV streams multicast over the system and implementing a conflict resolution protocol when a conflict of multicast addresses is detected, where the conflict resolution protocol utilizes automatically randomly selecting a preliminary multicast address from a defined range of addresses.

TRACKING NETWORK TRAFFIC OF LOCAL AREA NETWORK (LAN) SUBNETS IN A WIRELESS WIDE AREA NETWORK (WWAN)
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for tracking network traffic for local area network (LAN) subnets in a wireless wide area network (WWAN). In some implementations, a UE of the WWAN may assign a unique public IP address to each router of the LAN. The UE may transmit network traffic received from the LAN to the WWAN. The network traffic originating from any router of the LAN may be associated with the unique public IP address that was assigned to that router. The WWAN may use the unique public IP addresses to generate network traffic information that may indicate amounts of network traffic flowing from each router of the LAN. The WWAN, for example, may use the network traffic information to determine billing information for any router in the LAN.
ADDRESS ROTATION AWARE DYNAMIC HOST CONTROL PROTOCOL
A method comprises, at a wireless network controller of wireless access points through which wireless client devices that are wireless communicate with the controller: upon receiving, from a wireless client device, a dynamic host configuration protocol (DHCP) request having a media access control (MAC) address, determining whether the wireless client device rotated its MAC address from a previous MAC address to the MAC address; when the wireless client device rotated its MAC address, forwarding, to a DHCP service, the DHCP request with a notification of a MAC address rotation to cause the DHCP service to reassign a previously assigned Internet Protocol (IP) address to the wireless client device; and upon receiving, from the DHCP service, a DHCP offer asserting the previously assigned IP address, forwarding the DHCP offer to the wireless client device.
METHOD AND APPARATUS FOR CONFIGURING MEDIUM ACCESS CONTROL (MAC) ADDRESS FOR ULTRA-WIDEBAND (UWB) COMMUNICATION
Disclosed is a method of a first ultra-wideband (UWB) device, including identifying an extended MAC address of the first UWB device, generating a short MAC address of the first UWB device based on the extended MAC address, selecting one of the short MAC address and the extended MAC address as a MAC address identifying the first UWB device, and performing UWB communication with a second UWB device, using the MAC address, wherein the second UWB device operates as a controller defining and controlling a control message for UWB ranging, and wherein the first UWB device operates as a controlee using information included in the control message.
PROACTIVE NOTIFICATION OF WIRELESS CLIENT ADDRESS ROTATION
A network controller provides proactive notification of a wireless client device's address rotation to layer 2 (L2) and/or layer 3 (L3) devices. Traditional methods of device address discovery rely on broadcasting of address queries across a plurality of links until a path to a device having the queried address responds. As device address changes become more frequent in an effort to improve user privacy, traditional methods of address discovery impose a large burden on networks, reducing their performance and efficiency. By proactively propagating address changes to upstream devices, the need for broadcast oriented address discovery techniques is reduced, resulting in improved network performance.
Method and apparatus for management of extended mobile device identity information
A method of operating a terminal device to establish a radio resource control connection with network infrastructure equipment in a wireless telecommunications network, wherein the terminal device is associated with a previously-allocated temporary identifier that identifies the terminal device within the wireless telecommunications network; the method comprising: transmitting a first message to the network infrastructure equipment comprising an indication of a first portion of the temporary identifier; and transmitting a second message, which is separate from the first message, to the network infrastructure equipment comprising an indication of a second portion of the temporary identifier.
