20130301403 | FAST REROUTE USING LOOP FREE ALTERNATE NEXT HOPS FOR MULTIPOINT LABEL SWITCHED PATHS - The techniques of this disclosure provide local protection for network traffic in multipoint label switched paths (LSPs) due to link or node failure using loop-free alternate (LFA) next hops. The techniques include establishing a vanilla or point-to-point (P2P) LSP with LFA next hops between routers of a multipoint LSP for use in the event of link or node failure in the multipoint LSP. Upon a failure, the multicast traffic is tunneled between the routers using the P2P LSP with LFA to an alternate next hop with an associated label stack. The techniques of this disclosure define the label stack as including a P2P LSP label as well as a multipoint LSP label. In this way, the P2P LSP with LFA may be used for fast reroute (FRR) of traffic in the multipoint LSP until a convergence process completes for a new multipoint branch of the multipoint LSP. | 2013-11-14 |

20130301405 | Systems and Methods for Creating, Managing and Communicating Users and Applications on Spontaneous Area Networks - A Spontaneous Area Network (SPAN) is formed by mobile and fixed nodes using wireless transmission links between nodes, usually in a nearby geographical area. Applications allow users to create, join, leave, and manage SPANs and groups in a SPAN. Automatic procedures allow nodes to join other SPANs. Transmission power of the wireless network interface is dynamic, varying depending on battery level, type of information to transmit, state and topology of the network. A delay tolerant object layer abstraction creates, modifies, deletes, publishes, and handles Delay Tolerant Distributed Objects (DTDOs). A Patient Transport Protocol (PTP) ensures a reliable transport of information through the network while avoiding congestion conditions. An aggressive and explosive network protocol (AGENET) has routing and forwarding capacities and uses datagrams to establish communication between different nodes of the SPAN. Cooperation and diversity are exploited to react to node mobility that causes frequent changes in network topology and disconnections. | 2013-11-14 |

20130301408 | HYBRID DATAFLOW PROCESSOR - A network device that processes a stream of packets has an ingress front end. The ingress front end determines whether the packets are handled in a bounded latency path or in a best-effort path. The bounded latency path packets are granted a resource with a higher priority than the best-effort path packets. As the packets are processed through a number of processing stages, with processing engines, the bounded latency packets are processed within a period of time corresponding to a guaranteed rate. Resources are granted to the best-effort path packets only when the processing engines determine that the resource grant will not impact the latency bounds with respect to the first packets. | 2013-11-14 |
20130301409 | Flow Control For Multi-Hop Networks - Solutions are provided that allow a network device to apply flow control on the MAC layer while taking into account the priority of the frame of traffic.

A receiving device may then examine the fields of the frame to determine whether it should use priority-based pausing, and then examine other fields to determine which priority-levels to pause and for how long. This allows for improved efficiency in flow control at the MAC layer. Additionally, the tagged pause frames can be forwarded over multiple hops on Local Area Networks across a Metropolitan Area Network or Wide Area Network. | 2013-11-14 |

20130301500 | SYSTEMS AND METHODS FOR ENHANCED USER EQUIPMENT ASSISTANCE INFORMATION IN WIRELESS COMMUNICATION SYSTEMS - Systems and methods are disclosed for communicating enhanced user equipment (UE) assistance information between nodes in wireless communication systems. The UE achieves power savings and latency requirements more effectively by communicating its preferences, constraints and/or requirements to an evolved Node B (eNodeB) in the form of UE assistance information. The UE assistance information may include, for example, an indication of a preferred set of discontinuous reception (DRX) settings, current data traffic conditions, expected data traffic conditions, power or performance preferences, and/or an indication of the UE's mobility between cells. | 2013-11-14 |
20130301501 | METHODS AND APPARATUS FOR HANDLING MTC LONG DRX CYCLE/SLEEP LENGTHS - Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption. | 2013-11-14 |
20130301502 | METHOD AND APPARATUS FOR DATA TRANSMISSION IN A WIRELESS NETWORK - In a wireless local access network (WLAN), an access point (AP) broadcasts a beacon frame to a plurality of stations. The AP receives an indication frame from a station of the plurality of stations. The indication frame indicates that the station is available to receive a data packet for the station buffered at the AP. The AP indicates to the station a wakeup time for the station to wake up, and sends the data packet to the station at or after the wakeup time. | 2013-11-14 |
