Abstract: A network model is provided for modeling the nodes in networks such as access networks having a tree topology. Using the model, a network description can be generated that includes a node description for each node in the access network. A node description for a node includes an extra field to define child nodes relative to a modeled node. The node description also includes an extra field to describe a link from a modeled node to an upstream node. The connecting links and intermediate nodes of access nodes are exposed and can be manipulated. By providing a node description with child and link fields, a separate link data store can be avoided.
Abstract: Disclosed embodiments describe systems and methods for tunneling packets. A tunnel between a first intermediary device and a second intermediary device is established that encapsulates payload packets of transport layer connections between a client and a server. The first intermediary device identifies, from a first packet of a transport layer connection between the client and the server, packet header information. The first intermediary device populates a destination port and a source port of a header of a second packet to be transmitted via the tunnel. The destination port is populated with a predetermined destination port, and the source port includes a first hash of a tuple of the packet header information of the first packet. The second packet includes the first packet as a payload, and is load balanced across paths to the second intermediary device based on a second hash of the header of the second packet.
Abstract: Techniques described herein relate to performing wireless diagnostic analyses including execution and evaluations of interactive content resources executed by execution devices on and/or for separate content receiver devices. A multi-phrase diagnostic session may proceed with an execution of an initial set of diagnostic modules on an execution device, during which interactive content is transmitted/received from a connected receiver device. The results of the diagnostic modules may be evaluated in real-time and transmitted to a diagnostic analyzer server to select additional diagnostic modules for execution during the diagnostic session. The diagnostic analyzer server may select the additional diagnostic modules based on based on response data received via the content execution device to the interactive content of the previously executed diagnostic modules, and/or data received from additional data sources related to the content receiver.

Abstract: Methods and apparatus relating to the use of aggregated links, e.g., links in a bundle, are described. A normal link metric and a limited operation mode link metric a determined for a link bundle, the normal link metric having a lower value than the limited operational mode link metric. The status of links in a link bundle are monitored. Based on the number of currently operational links in a link bundle and a switching threshold, a decision is made whether to advertise the normal link metric, advertise the limited operation mode threshold or refrain from advertising any link metric. The use of the limited operation link metric facilitates the use of a partially failed link bundle providing an alternative routing path in the network that would not otherwise be available.
Abstract: A technique for determining signal quality of a radio access network, RAN, (502) comprising a plurality of transmission-reception points, TRxPs (504), is described. A method aspect of the technique comprises or initiates receiving a control message for determining the signal quality based on a measurement of a reference signal (516.21) from a second TRxP (504.4) at a radio resource. The control message is indicative of the radio resource for the reference signal relative to a synchronization signal (512.1) from a first TRxP (504.1; 504.2; 504.3) other than the second TRxP.

Abstract: Updating an uplink contention window size in a listen before talk process in a wireless communication system such as LTE may be done by the eNB if transport blocks contained in the starting subframe of a reference scheduled burst transmitted by a User Equipment are successfully decoded at the eNB. Otherwise, the User equipment adjusts the contention window size depending on information supplied by the eNB. This information identifies the first subframe in the burst whose transport block the base station was able to successfully decode. Depending on whether the User Equipment was first transmitting before or on the identified subframe, the User Equipment can either increase or reset the contention window size.

Abstract: Mitigation of inter-base station resynchronization loss in wireless networks including contention-based shared frequency spectrum is discussed. Aspects of such mitigation provide for base stations entering into an idle mode when a transmission opportunity occurs in a radio frame of the next resynchronization occasion. Additional aspects provide for the base station to signal a flexible listen before talk (LBT) frame length to the user equipment (UE), either with or without explicit signaling of the downlink-uplink division. Further aspects provide for the base station to signal a reset indication to UEs that will prompt the UEs to monitor for downlink channel reserving signals prior to the current LBT frame ending by the resynchronization occasion.
