Abstract: Methods and apparatus for handling failure of traffic forwarding (TF) systems in networks that include multiple zones each including a TF system between a production network and a border network. A TF system advertises routes in its zone and handles egress of packets from sources on the local production network onto the border network. TF systems may also advertise low-priority routes in other zones. If a TF system in a zone fails, sources in the zone may make connection requests to the low-priority routes. Instead of egressing the packets onto the border network, the requests on the low-priority routes are responded to with reset messages. Thus, the sources do not have to wait for a connection timeout, and packets for destinations in the zone are not egressed onto local border networks in other zones and sent through thin pipes between the local border networks.

Abstract: Some demonstrative embodiments include devices, systems and methods of selecting a mobility mode of a User Equipment (UE). For example, a UE may include a Wireless Local Area Network (WLAN) transceiver; a cellular transceiver to communicate with a cellular node; an Access Network Discovery and Selection Function (ANDSF) client module to communicate with an ANDSF server; and a controller to select a WLAN mobility mode from a cellular/WLAN aggregation mode and an ANDSF mode.

Abstract: Rather than using a large number of transceivers (transmitter/receiver pairs) operating in parallel, Access Points with multiple channels are used to aggregate, or stack, transmitted response communications, e.g., transmitting multiple acknowledgements (ACKs) in a single packet to one or more sources of received packets. The method includes sending on a plurality of channels, by each of a plurality of respective first nodes, a communication to a second node, receiving on the plurality of channels, by the second node, the communication from each of the plurality of first nodes and sending, by the second node, a transmission that contains a response to each communication that was successfully received from each of the plurality of first nodes. The response to each of the plurality of first nodes is part of a single message sent by the second node.

Abstract: An aspect of present invention discloses a transceiver processing hardware (“TPH”) which is configured to process wireless information based on a constellation map. The TPH includes a minimum mean square error (“MMSE”), an inverse discrete Fourier transform (“IDFT”), and a demapper. The MMSE provides estimation of received bit stream, and the IDFT generates a list of samples associated with frequency of the bit stream. The demapper configured to discard unused constellation points includes a minimum function component (“MFC”) and a special treatment component (“STC”). While MFC is able to receive a bit stream representing a symbol corresponding to a quadrature amplitude modulation (“QAM”), the STC is configured to force one or more infinity values to facilitate generation of an LLR value representing a logic value of the symbol.

Abstract: The disclosure provides for a method of interference detection using adaptive energy detection in unlicensed spectrum. The method can include a first modem operating according to a first radio access technology (RAT) receiving a message from a network entity operating according to the first RAT. The first modem sends a detected energy level value to a second modem that is using a second RAT, where the detected energy level value is based at least on the measured energy level of the received message. The second modem adjusts an energy detection threshold based on the detected energy level value received from the first modem. In an aspect, the first modem receives messages from a plurality of network entities operating according to the first RAT, where the detected energy level value is determined based on measured energy levels of the plurality of received messages.

Abstract: Some embodiments override network or router level path selection with application or server controlled path selection by repurposing the type-of-service (ToS) or differentiated services header field. A mapping table maps different ToS values to different available transit provider paths to a particular destination. A server generating a packet to the destination selects one of the available paths according to any of load balanced, failover, or performance optimization criteria. The server sets the packet header ToS field with the value assigned to the selected path. A router operating in the same network as the server is configured with policy based routing rules that similarly map the ToS values to different transit provider paths to the particular destination network. Upon receiving the server generated packet, the router routes the packet to the destination network through the transit provider path identified in the packet header by the server set ToS value.
