The present invention relates to methods and apparatus for providing services in high density deployments using dynamic assignment Virtual Local Area Network (VLAN) stacking during client device authentication. An exemplary method includes the steps of: receiving wirelessly, by a first Access Point (AP), a first authentication request message including first user equipment device identification information from a first user equipment device; generating, by the first AP, a second message based on the first authentication request message, the second message including the first user equipment device identification information and location information for the first AP; transmitting, by first AP, the second message to a first server; and receiving in response to the second message, by the first AP, a third message, said third message including dynamically assigned stacked VLAN information including a first Service-VLAN Identifier and a first Customer-VLAN Identifier dynamically assigned to the first user equipment device.

Methods and apparatus for implementing VLAN stacking for seamless roaming in high density wireless networks

A broadband network gateway (BNG) implementing a plurality of virtual gateway routers, each virtual gateway router (VGR) operable to serve as a gateway router for a particular local area network (LAN) of a plurality of LANS, receives a human presence indicator from a customer premise equipment (CPE) of a LAN, the human presence indicator indicating one of that a human has been detected by the CPE or that no human has been detected by the CPE for a predetermined period of time. In response, the BNG performs a quality of service (QOS) action, on a VGR that serves as the gateway router for the LAN, that one of enhances a current QOS associated with the first LAN or decreases a current QOS associated with the first LAN.

Methods and systems proxy address resolution protocol processing in a distributive local area network is described. The method for proxy address resolution protocol processing includes sending, by a first subscriber device, an address resolution protocol processing broadcast to obtain a second subscriber device address, wherein the first subscriber device and the second subscriber device are in isolated routing prefix domains within a routing prefix, receiving, by the first subscriber device from a gateway, a second subscriber device proxy address for the second subscriber device, and communicating, between the first subscriber device and the second subscriber device via the gateway, using the second subscriber device proxy address.

Methods and systems for flexible nodal layer 3 overlay of layer 2 traffic is described. A network includes an access device for receiving layer 2 traffic from user devices, a packet inspection device for inspecting the layer 2 traffic, and a layer 3 tunnel instantiation device for encapsulating the layer 2 traffic into layer 3 traffic. The layer 3 tunnel instantiation device provides a first tunnel endpoint for a layer 3 tunnel, which is connected to a second tunnel endpoint instantiated at a network gateway. The layer 3 tunnel instantiation device establishes a moveable demarcation between a layer 2 domain and a layer 3 domain with respect to the packet inspection device, where the access device and the packet inspection device operate in the layer 2 domain. The layer 3 traffic is transmitted over the layer 3 tunnel.

Flexible nodal layer three overlay of layer two traffic

A bridged gateway coupled to a local area network (LAN) receives a layer 2 frame from a device coupled to the LAN. The bridged gateway forwards, to a network gateway router that provides layer 3 routing services for the LAN, the layer 2 frame via a layer 2 tunnel. The bridged gateway determines that the layer 2 frame comprises a dynamic host configuration protocol (DHCP) discover message, the DHCP discover message including an initial message in a four message sequence used by the network gateway router and the device to provide an internet protocol (IP) address to the device. The bridged gateway determines that the four message sequence between the device and the network gateway router did not complete. The bridged gateway, in response to determining the four message sequence did not complete, sends, to a destination, an alert that comprises information indicating a problem with the network gateway router.

Systems, methods, and devices for performing targeted filtering of network traffic generated by user equipment (UE) devices connected to a customer premise equipment (CPE) device in a communication system that includes a distributed residential gateway. A network server may determine that the communication system includes a UE device that is compromised, misconfigured, or operating outside normal communication parameters, identify the UE device, determine an Internet protocol (IP) address or a media access control (MAC) address of the identified UE device, generate a quarantine request message that includes the IP address or the MAC address of the identified UE device in response to determining that the preconfigured virtual local area network access control list (VACL) on the CPE lists source IP addresses from which the CPE will filter outbound traffic, and send the generated quarantine request message to a bridged residential gateway (BRG) associated with the CPE device.

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.

Various embodiments comprise systems, methods, mechanisms, and apparatus by which a network operator such as a wireline internet service provider (ISP) may determine that an endpoint device has one or more other wireless devices tethered to it, such as a mobile handset providing dual-Wi-Fi ad-hoc tethering (i.e., connected to a high-speed Wi-Fi network while simultaneously providing Wi-Fi connections to wireless devices tethered to the mobile handset), by monitoring Transmission Control Protocol (TCP)/IP traffic flow associated with endpoint devices (i.e., to or through endpoint devices), characterizing these traffic flows in accordance with one or more error indicative criteria to establish thereby a baseline profile of error indicative criteria that is indicative of a TCP/IP traffic flow associated with an endpoint device that is not associated with tethering (e.g., a rate or number of duplicate ACKs), wherein deviations from the baseline profile of error indicative criteria beyond a threshold are indicative of a TCP/IP traffic flow associated with an endpoint device that is associated with tethering.

Identifying a tethered device using TCP error transmissions

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 a solicited unicast router advertisement that includes a special prefix in response to determining that the UE device is eligible to receive special treatment based on the link-layer address. The network device may send the UE device a solicited unicast router advertisement that includes a base prefix in response to determining that the UE device is not eligible to receive special treatment based on the link-layer address.

Systems, methods, and devices for instantiating both a private network service (PrNS) gateway virtual network function (VNF) and a public network service (PuNS) gateway VNF for a user equipment (UE) device that is associated with a PrNS and communicatively attached a public WiFi network allow users to access the same set of feature-rich network services (including layer 2 services) when connected through a public hotspot WiFi network as when connected through a home or local area network WiFi network.
