Abstract: A technique of operating a network node in a media distribution network in which media data are transmitted in media bursts to a buffer of a media client is described. Each media burst is followed by an idle period in which no media data are transmitted. A method aspect of this technique comprises determining a fill level of the media client buffer, and generating a media burst. Media burst generation includes adjusting at least one of a media data volume of the media burst and a duration of an idle period following the media burst dependent on the fill level of the media client buffer.

Abstract: A network, a method and devices (i.e., mobile node, access router, home agent, destination home agent) are described herein for enabling an efficient hybrid route optimization between two mobile endpoints so they can re-direct their data traffic to an optimal path without exchanging any mobility signaling messages.

Abstract: In scenarios where the quality of service is negotiated through a signalling layer whereas the services are actually carried through a bearer layer, application functions at the signalling layer are not always aware of how quality of service is individually accomplished at the bearer layer on a service basis. The invention provides a method and devices whereby events are detected on a service data flow basis at a detection device in the bearer layer and notified towards an application device in the signalling layer via a control device between the signalling and the bearer layer. The list of events to be notified is obtainable at the control device from the application device and is included in Quality of Service related rules, along with service data flow filters. This Quality of Service related rules are provided to the detection device for inspecting individual service data flows in order to detect and notify the indicated events.

Abstract: A system and method that differentiates between Machine-to-Machine (M2M) traffic and User Equipment (UE) traffic when scheduling radio Resource Units (RUs) to M2M terminals and UEs in a Long Term Evolution (LTE) network. Prior to allocation of RUs, the available RUs are divided into two disjoint sets—a UE-specific set (dedicated for UE users) and an M2M-specific set (dedicated for M2M terminals). A hybrid scheduler allocates RUs to M2M terminals from the M2M-specific set only. Any unallocated RUs from the M2M-specific set and the RUs assigned to the UE-specific set are then allocated to the UEs. New M2M-specific Quality of Service Class Indicators (QCIs) are defined as well for classifying M2M traffic only. These new QCIs are disjoint from the existing QCIs, which classify the UE traffic only. The M2M-specific QCIs separate M2M traffic classification from UE traffic classification so as not to impact UE human users' Quality of Experience (QoE).

Abstract: In accordance with one embodiment of the present disclosure, a method for managing communication in a wireless network includes determining a first value indicating a level of use for a scheduled data channel for one or more of a plurality of sectors served by a first base station and determining a second value indicating a level of use for a random access channel for one or more of the plurality of sectors served by the first base station. The method also includes selecting a respective subframe for random access transmissions for each of the sectors served by the first base station based on the first value and the second value. Additionally, the method includes transmitting configuration information to the first base station. The configuration information indicates a subframe selected for each of the sectors.

Abstract: An ingestion controller, system, and method for managing ingestion of electronic content in a Content Distribution Network (CDN). The content is received from one or more content sources (CSs) through an inbound content pipe having a maximum bandwidth capacity. A database stores bandwidth weightings assigned to each CS by a network Policy Management System (PMS). The bandwidth weighting assigned to each CS corresponds to a fraction of the maximum bandwidth capacity of the inbound content pipe. An input buffer receives the content from the CSs in one or more input buffer queues associated with the CSs. A content retrieval mechanism retrieves the content from the input queues at an upload rate for each CS based at least on each CS's assigned bandwidth weighting, thereby causing a flow control mechanism to control the upload bitrate of each CS in proportion to the bandwidth weightings.

Performance data is determined for one or more applications. A service path is assigned by steering traffic to a particular instance of each of the one or more applications using the performance data. The steered traffic is forwarded to a next application based on a current position along a service path.

Abstract: A simplified but accurate soft-symbol determination process represents one of the advantages provided by the example embodiments disclosed herein. In this regard, a mapping function “maps” symbol estimates to corresponding soft symbol values, which may be used in interference mitigation, joint detection processing, etc. Whether the mapping function is implemented on-the-fly as a live calculation or is embodied in a look-up table, it advantageously operates on the symbol estimates directly, rather than requiring the derivation of corresponding soft bit values or the like, and it maps each symbol estimate to its “expected value,” i.e., the weighted sum of constellation point probabilities. Moreover, the mapping function may be changed dynamically—e.g., by using different look-up tables—to account for changing reception conditions and/or different modulation schemes or other signal parameters associated with the symbols being estimated and mapped to soft symbol values.

Abstract: A method performed by a slave network edge node (e.g., a Broadband Network Gateway BNG2) for enhancing a Long Term Evolution (LTE) backup channel in the event of a failure of a master network edge node (e.g., BNG1) in a wireline network. When BNG2 detects the failure of BNG1, BNG2 sends a failure update message to a Packet Data Network Gateway (PDN GW) of an LTE network. The PDN GW provides a backup channel for the CPE to reach the wide area network over a mobile tunnel. Before the failure the mobile tunnel has an end point at BNG1, and the failure update message notifies the PDN GW that the end point of the mobile tunnel has changed from BNG1 to BNG2. After BNG2 receives a failure acknowledgement message from the PDN GW, BNG2 routes the traffic from the PDN GW over the mobile tunnel to the wide area network.

Abstract: This disclosure describes apparatuses, methods and computer program products for reducing location update signaling in a mobile communications network. In some embodiments, a method is provided in which a mobility management and control (MMC) rule is provided to a location aware network node (LANN) (e.g., an MME). The MMC rule includes location information that specifies a location and an action associated with the location. In response to receiving mobility information pertaining to a mobile communication device (MCD), the LANN uses the mobility information and the location information to determine whether or not to perform the action associated with the location information.

Abstract: A method is implemented by a network device for a fast traffic recovery process for the virtual redundant router protocol (VRRP), where improved speed in a switchover from a master VRRP router to a backup VRRP router is obtained by synchronizing an address resolution protocol (ARP) cache between the master VRRP router and the backup VRRP router such that after the switchover the backup VRRP router functions as a new master VRRP router and does not need to relearn media access control (MAC) address to Internet Protocol (IP) mappings of hosts using the new master VRRP as a gateway. The process involves receiving an ARP entry on an interface of the network device and checking whether the network device is configured as the master VRRP router. The process then sends a gratuitous ARP message to the backup VRRP router in response to the network device being the master VRRP router.

Abstract: A method and network element identify a set of bit indices for forming compressed keys, which are used to map a set of keys of corresponding input values to assigned lookup values in a hash table, where the keys of the input values have colliding hash values according to a hash function of the hash table. The method includes a set of steps including receiving the set of keys. The bits of the set of keys are traversed to find a best split bit index. The set of keys are split into two subsets according to the best split bit index. A check is made whether all of the set of keys have been split into separate subsets. A selected best split bit is added to a bit index. Alternate split bits are tallied and a bit is selected with a highest tally to add to bit index.

Abstract: Methods and apparatus for determining an estimated physical location of a fault in a pipeline or electrical transmission line using localization devices coupled thereto. In an embodiment, a first and second localization device each generate time values representing times when the respective localization device detected the fault. The estimated fault location is calculated, by one of the localization devices or a separate computing device, based upon the reported time values. In some embodiments, the calculation is further based upon characteristics of the pipeline or electrical transmission line, or based upon characteristics of matter transported through the pipeline. In some embodiments, the localization devices transmit time or sequence values to the other device, and the values received by the devices just before the detection of the fault may additionally be utilized to calculate the estimated physical location of the fault.
