  • Publication number: 20130064065
    Abstract: Typical transceivers have multiple near-end and multiple far-end crosstalk cancellation filters. Crosstalk cancellation is one of the largest contributors to power dissipation in the DSP portion of high speed Ethernet transceivers. By detecting the cable type, a transceiver could automatically turn off its crosstalk cancellation filters when driving shielded twisted pair (STP) cables and substantially reduce the overall power dissipation in this configuration. Adaptive digital crosstalk cancellers automatically adjust the coefficients of a digital filter to match the coupling function between two channels. The impulse response of an optimal crosstalk cancellation filter can be used to determine a metric indicating the amount of coupling between the two channels. STP cables will have a much lower amount of coupling between wire-pairs than unshielded twisted pair cables.

  • Publication number: 20130064073
    Abstract: The embodiments disclosed herein provide a mechanism for sharing protection resources in an arbitrary network topology involving pre-computing the protection resources so that data-plane-based protection can be used to activate the protection resources upon detection of a failure, thus, providing faster switching times than typical control-plane-based solutions. This is accomplished by configuring a mesh network to include, for a working path in the network, one or more protection paths with the same end nodes as the working path, where each protection path includes at least one intermediate node that is not part of the working path. The intermediate node accepts a protection request from one of the end nodes and determines whether a local resource for a protection path is available.

  • Publication number: 20130064076
    Abstract: Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network. These embodiments can advantageously be deployed in dense urban areas and/or co-located with wireless access nodes, such as base-stations of a cellular wireless communication system. Preferably wireless links between constituent network nodes are set-up hierarchically. A basic result of this is that peer-to-peer (child-to-child) communication is generally prohibited and circuits are forced to conform to a topology. The multi-hop wireless backhaul network may be used to carry delay sensitive, high-density last mile circuit traffic over Non-Line-Of-Sight (NLOS) broadband radio links. Moreover, some embodiments of the invention provide a method of path-healing for re-routing of circuit traffic from circuits that have experienced catastrophic failures.

  • Publication number: 20130064079
    Abstract: Flow monitoring tasks are assigned to a set of switches in a split architecture network to optimize network-wide flow monitoring. The assignment maximizes the number of monitored flows and reduces overhead of the flow monitoring. A controller receives an estimated traffic volume for each path in the network. The controller calculates, for all of the switches and all of the paths, sampling fractions that maximize the number of the flows sampled by the switches. In response to a request for setting up a new flow to traverse one of the paths in the network, the controller assigns the new flow to one of the switches that are located on the one of the paths, based on the sampling fraction for the assigned switch and the one of the paths, the bandwidth constraint and the memory constraint.

The operation(s) to be performed and the order of performing the operation(s) may be dependent on the number of existing packet filters to be replaced (N) and the number of new packet filters (M). If N=M, then N packet filters in a traffic filter template may be replaced with a single operation. If N>M, then M packet filters in the traffic filter template may be replaced first, and N?M packet filters may be deleted from the traffic filter template next. If N<M, then M?N new packet filters may be added to the traffic filter template first, and N packet filters in the traffic filter template may be replaced next. In another scheme, packet filters are modified with a single operation using dummy packet filters, if needed.

Due to an increase of path costs in wireless areas, the path control device recalculates path costs over a network so as to carry out switching to an appropriate data communication path, e.g. a LAN with blocking a wireless line. When a wireless band is recovered due to an AMR function, the wireless monitoring device sends a path cost change request to the path cost control device, which in turn reduces a path cost at a wireless line port. Additionally, the communication path control device recalculates path costs over a network so as to switch over data communication paths. Thus, it is possible to select an optimum data communication path with a low cost.

  • Publication number: 20130064096
    Abstract: Network traffic information from multiple sources, at multiple time scales, and at multiple levels of detail are integrated so that users may more easily identify relevant network information. The network monitoring system stores and manipulates low-level and higher-level network traffic data separately to enable efficient data collection and storage. Packet traffic data is collected, stored, and analyzed at multiple locations. The network monitoring locations communicate summary and aggregate data to central modules, which combine this data to provide an end-to-end description of network traffic at coarser time scales. The network monitoring system enables users to zoom in on high-level, coarse time scale network performance data to one or more lower levels of network performance data at finer time scales.

  • Publication number: 20130064097
    Abstract: The invention relates to communication systems and to systems and methods for implementing adaptive call admission control (CAC) in such systems. Adaptive call admission control can determine what CPE to base station calls (connections) are allowed at any given time. CAC, coupled with precedence, can further determine what connections are suspended if less bandwidth is available than is currently committed. Multiple techniques are disclosed to select connections for suspension. These techniques include suspending enough connections through the affected CPE until there is enough bandwidth to meet the remaining commitment, randomly (or in a round robin fashion) choosing connection to suspend from the entire set of connection, and using precedence priority levels.

  • Publication number: 20130064103
    Abstract: There is provided a mechanism for reporting buffer status information to a communication network control element when transmission via both a licensed and an unlicensed spectrum is conducted and offloading of traffic is executed. After an offloading value indicating the amount of traffic which can be offloaded from a transmission over a licensed spectrum to a transmission over an unlicensed spectrum is estimated, the UE determines a buffer size of at least one transmission buffer used in a transmission over the licensed spectrum and the unlicensed spectrum. Then, buffer status information is sent to the eNB wherein the estimated offloading value is considered. The eNB can then allocate resources for the transmission over the licensed band while benefits by the offloading to the unlicensed band are considered in the resource allocation.

  • Publication number: 20130064108
    Abstract: A network intelligence solution (NIS) is arranged to access a stream of IP (Internet Protocol) packets associated with communications over a mobile communications network between mobile equipment employed by a user and a remote server such as a web server. When the mobile equipment accesses the network, the TAC (Type Allocation Code) portion of the IMEI (International Mobile Equipment Identity) is extracted from the IP stream at the NIS so that information about the mobile equipment such as technical information (e.g., manufacturer, model, operating system, etc.) and market data (e.g., market share, average sales price of the equipment, etc.) can be retrieved from one or more databases. The NIS performs deep packet inspection (DPI) to measure Internet usage by the mobile equipment user with each network access. Relationships between variables and/or observed data in each of the Internet usage data and mobile equipment information may then be identified.

    Abstract: A network intelligence solution (NIS) is arranged to tap a stream of IP (Internet Protocol) packets traversing a node in a network that supports a mobile communications service between mobile equipment employed by subscribers in a universe of subscribers to the service and one or more remote servers such as web servers. The NIS performs deep packet inspection to measure Internet usage by the universe of subscribers as well as usage by a subscriber panel that is a representative subset of the universe. A unique network identifier is generated, for example using the MSISDN (Mobile Subscriber Integrated Services Digital Network Number) associated with each subscriber which is anonymized, to enable socio-demographic information collected from the subscriber panel to be correlated to the panel's Internet usage. The correlations can then be extrapolated to make generalizations about socio-demographics of the larger subscriber universe.

  • Publication number: 20130064110
    Abstract: Many services measure quality of service (QoS) according to abstract metrics based on general heuristics of QoS determinants (e.g., VoIP service providers may presume that QoS is predominantly determined by network performance). However, users' QoS perceptions are often based on their experiences with particular activities of the service, which may utilize different service paths having different QoS determinants. Therefore, QoS may be measured by identifying the activities of the service, and the dependencies among the components of such services; for respective activities and dependencies, identifying a service path from the source to the user, and the segments comprising the service path; measuring the quality of the segments of the service path; and calculating the QoS of the activity according to the QoS of the segments of the service path providing the activity. This approach may yield QoS information of greater relevance to the users' experience and with greater analytic value.
