Techniques for performing optimized handovers of a client device between access points in wireless networks are provided. A first access point exchanges packets with a client device. The first access point receives a disassociation notice from the client device. In response to the disassociation notice, the first access point buffers one or more packets received for the client device in a first buffer. The first access point receives an indication from a controller to transmit the one or more packets in the first buffer to a second access point. In response to the indication, the first access point transmits the one or more packets in the first buffer to the second access point.

Handovers in wireless controller-based systems

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 random IP address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a random IP address that cannot be used to identify the endpoint device or service. The client device may then communicate data packets to the server using the random IP address as the destination address, and a gateway that works in conjunction with DNS can convert the random IP address to the actual IP address of the server using NAT and forward the data packet onto the server.

Randomizing server-side addresses

In one embodiment, an apparatus comprising networking circuitry adapted to receive, at a mobile network operated by an SP, flows associated with enterprise applications executing on device(s) in an enterprise network, the device(s) including a CPE and/or one or more devices behind the CPE, and processing circuitry adapted to vary, during a duration in which there is IP connectivity between the CPE and the mobile network, a pool of dedicated bearers for binding the flows, in response to at least part of changes occurring during the duration with respect to the flows, wherein the changes include variations during the duration in number of the flows and/or differences during the duration in detected characteristics of the flows, the detected characteristics of the flows having been detected based on inspection of respective packet(s) of the flows, and bind at least part of the flows to respective dedicated bearers included in the pool.

Adaptive quality of service for enterprise traffic

Techniques are provided for operator specific customization of a network service configuration. In some embodiments, an operator defines a mapping between an application executing on a user equipment (UE) and a network service configuration. In some embodiments, the network service configuration indicates whether the application is to be supported via a UPF instance located within the core network or deployed at a network edge. The mapping is then provided to the UE, and passed back to the core network, for example, when the UE establishes a connection on behalf of the UE application. The core network then supports the UE application consistent with the configuration specified by the mapping.

Techniques for binding operator-defined network service configurations to applications

A user plane function (UPF) node may receive a packet for traffic associated with a user equipment (UE). During packet classification, the UPF node may identify that a packet filter for the packet is not found in a packet filter set of an existing Quality of Service (QoS) Flow. In response, the UPF node may configure the packet filter in the packet filter set of the QoS Flow based on a flow tuple of the packet. The UPF node may send, to a control plane function node, a message which indicates a request for adding the flow tuple to the QoS Flow. The message may be for triggering communication of a message which indicates a session modification command for receipt by the UE, for adding an uplink packet filter that is based on the flow tuple for the QoS Flow.
