Abstract: Methods and apparatus, including computer program products, implementing and using techniques for processing a data packet in a packet forwarding device. A data packet is received. A virtual local area network destination is determined for the received data packet, and a set of rules associated with the virtual local area network destination is identified. The rules are applied to the data packet. If a virtual local area network destination has been determined for the received data packet, the data packet is output to the destination, using the result from the application of the rules. If no destination has been determined, the data packet is dropped. A security system for partitioning security system resources into a plurality of separate security domains that are configurable to enforce one or more policies and to allocate security system resources to the one or more security domains, is also described.

Abstract: Methods for preventing timing collisions in a wireless communication network include transmitting a data uplink symbol of normal duration via a first base pair using a first timing advance (TA) corresponding to the first base pair. Scheduling to transmit a second uplink symbol via a second base pair (BP) corresponding to the transmit RF chain. Predicting a timing collision will occur based on a different between the first TA and a second TA corresponding to the second BP. Preventing the timing collision by: reducing the duration of the second symbol by an adjustment amount calculated based on the first TA and the second TA; inserting a guard interval to delay transmission of the second symbol by the calculated adjustment amount; and increasing the duration of a cyclic prefix of the second symbol but refraining from transmitting a portion of the enlarged CP.

Abstract: A Wi-Fi Direct Group Owner stores network parameters needed for proper operation of a peer-to-peer network. These include the network name and identifier, the power save schedule, the security settings, MAC address of all of the group members, etc. To reduce the need for a single Group Owner, this information is distributed. As each new device is added to the network, all of these parameters are passed via IEEE 802.11 data packets from the device acting as the Group Owner to the new peer device. This way, the new peer device has all of the information about the group at the time that it joins. Any device in the Resilient Peer Network can temporarily take on the role of a traditional Wi-Fi Direct Group Owner (admission control). Selection of which peer will act as a Group Owner will depend on a user action or network event.
