Abstract: In some implementations, an ingress network device of a multiprotocol label switching (MPLS) network may receive a packet destined for a destination network device. The ingress network device may determine, based on the packet, a secure function to secure the packet and a label associated with a label-switched path (LSP) from the ingress network device to an egress network device of the MPLS network that is associated with the destination network device. The ingress network device may encrypt, using the secure function, the packet to generate an encrypted packet. The ingress network device may generate an MPLS packet comprising: an MPLS header that includes the label and a secure function indicator, a secure MPLS data header that includes information identifying the secure function, and an MPLS payload that includes the encrypted packet. The ingress network device may forward, based on the label, the MPLS packet.

Further, which is available to the network nodes throughout the wireless network. Thereby, any network node in the wireless network, such as the first network node, is able to perform distribution of a paging message to all network nodes that support a particular RANA, as registered in the database.

Abstract: A system receives vehicle metric data from a gateway device connected to a vehicle via a network connection. In a first power mode, the vehicle gateway device gathers vehicle metric data related to operation of the vehicle and/or location data and sends requested vehicle metric data to the system. Based on a lack of input, the vehicle gateway device enters a standby power mode to reduce the power consumption of the vehicle gateway device. The vehicle gateway device reduces the power consumption by reducing activity of the vehicle gateway device. Instead of reinitiating a network connection periodically to receive requests for vehicle metric data from the system, the vehicle gateway device maintains the network connection by sending keep alive messages between the vehicle gateway device and the system. The system uses the maintained network connection to request vehicle metric data.
