    Abstract: In one embodiment, a system, apparatus, and method are described for requesting access authorization from an access network access point (AP) via an access network interface, generating at a processor a public-private key pair (320) to be used to generate a cryptographicaliy generated address (320) upon receiving the access authorization, sending a secure neighbor discovery (SeND) - neighbor solicitation (NS) to the AP via the access network interface after the public-private key pair has been generated (340), receiving a signed user location information (ULI) from the AP in response to the SeND- NS (360), and sending the signed L-l-.l to one of a 3GPP mobility controller or an emergency service via a 3GPP network interface (380). Related systems, apparatuses, and methods are also described.

    Abstract: In one embodiment, a method includes discovering at a network controller, a topology and link capacities for a network, the network controller in communication with a plurality of spine nodes and leaf nodes, the link capacities comprising capacities for links between the spine nodes and the leaf nodes, identifying at the network controller, a flow received from a source at one of the leaf nodes, selecting at the network controller, one of the spine nodes to receive the flow from the leaf node based, at least in part, on the link capacities, and programming the network to transmit the flow from the spine node to one of the leaf nodes in communication with a receiver requesting the flow. An apparatus and logic are also disclosed herein.

    Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a virtual IP (VIP) address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a virtual network of VIP addresses. The client device may then communicate data packets to the server using the VIP address as the destination address, and a virtual network service that works in conjunction with DNS can convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.
