Abstract: Low latency wireless communications may be provided. A client device may be authorized for a first association in response to the client device making a first concurrent association request that may include a first Media Access Control (MAC) address. In response to authorizing the client device for the first association, an Endpoint Identifier (EID) associated with the client device may be registered with a first Routing Locator (RLOC) in a map server, the first RLOC being associated with the first MAC address. The client device may then be authorized for a second association in response to the client device making a second concurrent association request that includes a second MAC address. In response to authorizing the client device for the second association, the EID associated with the client device may be registered with a second RLOC in the map server, the second RLOC being associated with the second MAC address.

Abstract: Multiple authenticated identities for a single wireless association may be provided. First, an Access Point (AP) may provide an association with a client device. The AP may then establish, on the association, a first authenticated session for the client device based on a first media access control (MAC) address and a first identity. Next, the AP may establish, on same the association, a second authenticated session for the client device based on a second MAC address and a second identity.

Abstract: A network management center includes a Dynamic Host Configuration Protocol (DHCP) server. The network management center obtains from an identity server, client information indicating authentication of a client device in a wireless network that is connected to a network fabric. The network management center obtains from an edge node in the network fabric an Internet Protocol (IP) address request for the client device. The IP address request including a fabric domain identifier associated with the edge node. The network management center allocates an IP address for the client device based on the client information obtained from the identity server and the fabric domain identifier contained in the IP address request obtained from the edge node. The network management center provides to the edge node an Identifier Locator Addressing (ILA) address based on the IP address.

Abstract: Dynamic policy mapping is provided via mapping, by an Access Point (AP), a plurality of applications to a set of privilege groups for Quality of Service (QoS) levels in a network; transmitting the mapping of the privilege groups to a client device; receiving packets from the client device including QoS markers; and in response to determining that the QoS markers received from the client device do not match the privilege groups for the packets, performing a corrective action on the client device, wherein the corrective action includes one or more of: disassociating the client device from the network; and retransmitting the set of privilege groups to the client device. In some embodiments, the privilege groups are transmitted before the client device is associated with the AP, enabling the client device to select what AP to associate with based on the privilege groups.

Abstract: Techniques are described for extending a cellular quality of service bearer through an enterprise fabric network. In one example, a method obtaining, by a first switch of a network, a packet to be delivered to a client connected to the network via a cellular access point; identifying quality of service (QoS) bearer information associated with the packet, wherein the QoS bearer information is associated with a radio access bearer for the client and the QoS bearer information comprises a bearer indicator and a QoS class identifier; providing a fabric tunnel encapsulation for the packet, wherein the bearer indicator and the QoS class identifier are included within the fabric tunnel encapsulation of the packet; and forwarding the packet within the fabric tunnel encapsulation toward a second switch of the network via a fabric tunnel, wherein the cellular access point is connected to the network via the second switch.

Abstract: Techniques are described for integrating cellular access within an enterprise fabric. In one example, a method includes obtaining, by a cellular termination function via a cellular access point, a request from a client for data plane connectivity via a network, wherein the cellular access point is registered within the network and is in communication with a first switch of the network; obtaining, by the cellular termination function, cellular policy information and enterprise policy information for the client; obtaining, by the cellular termination function, an Internet Protocol (IP) address for the client; and establishing data plane connectivity for the client with the network via the cellular access point, the first switch of the network, and a second switch of the network based, at least in part, on the IP address for the client, wherein the second switch connects the network with one or more data networks.
