Abstract: 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.

Abstract: 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.

Abstract: A method for providing a differentiated feature to a first user equipment (UE) connected to a local area network (LAN) implemented by a router connected to a customer premises equipment (CPE) provisioned with a default feature associated with a first service tier of a plurality of service tiers provided by an internet service provider includes obtaining data indicating the first UE has connected to the LAN and determining the first UE is eligible for a second service tier of the different tiers. In response to determining the first UE is eligible for the second service tier, the method includes causing the CPE to be dynamically provisioned for a differentiated service associated with the second service tier. The method includes sending a message to the router to configure the router to provide the differentiated feature to the first UE.

Abstract: 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.

Abstract: The presentation invention relates to methods and apparatus for a mobile device to discover the hidden SSID of a network. An exemplary method embodiment includes the steps of: receiving, at the mobile device, a first beacon frame having a Service Set Identifier (SSID) field set to NULL from a first Access Point; determining, at the mobile device, based on information received from the first Access Point that the mobile device is provisioned to connect to a first network advertised by the first beacon frame; discovering, by the mobile device, a first SSID name for the first network advertised by the first beacon frame for which the mobile device is provisioned. In another embodiment the mobile device associates with the first network after discovering the first SSID name.

Abstract: Automatic local gateway router backup of a network gateway router is disclosed. A local gateway router communicatively coupled to a local subnet determines that a network gateway router that serves as a default gateway router for the local subnet has stopped responding. The local gateway router and the network gateway router are configured to communicate with one another via a tunnel implemented by a tunneling protocol. In response to determining that the network gateway router has stopped responding, automatically switching, by the local gateway router, from a tunneling mode to a routing mode, such that the local gateway router becomes the default gateway router for the local subnet.

Abstract: A method for collecting duplicated packets from a plurality of nodes provided on a network includes receiving a traffic profile which includes one or more parameters of packets which are to be captured by the plurality of nodes. The method further includes transmitting the traffic profile to each of the plurality of nodes provided on the network and receiving duplicated packets from the plurality of nodes. The duplicated packets correspond to packets which have been duplicated from packets which are captured by the plurality of nodes and satisfy the traffic profile.
