A distributed application may be updated by using information provided by the application to determine grouping, sequencing, and whether or not to advance an update sequence. The application may provide input to an update sequence, and may cause the update sequence to repair one or more replicas prior to updating. The update mechanism may be used to change the distributed application topology as well as make changes to the application executable code, application configuration, quest operating system, virtual machine, and host systems, among others. In some cases, the distributed application may use a quorum to determine which version is current, and the quorum may change during the update process.

Coordinated Upgrades In Distributed Systems

Techniques and mechanisms are disclosed that enable a data collection system to adaptively control collection of data from one or more external data sources. At a high level, adaptively controlling collection of data from external data sources may include collecting performance information related to one or more data collection nodes and, in response to analyzing the collected performance information, adapting rates at which the data collection nodes send data collection requests to external data sources. Data collection performance information generally may include, but is not limited to, network traffic data, error messages generated by external data sources and/or data collection nodes, computing device performance information, and any other types of information related to a data collection node's ability to collect data from external data sources.

Adaptive control of data collection requests sent to external data sources

An approach is provided for upgrading components of a cluster. One or more components of at least one server of a cluster of servers are determined to be upgraded. Status information of the cluster, the at least one server, or a combination thereof is determined. It is determined whether to initiate another upgrade of one or more other components of the at least one server, another one of the servers, or a combination thereof based, at least in part, on the status information.

A method and apparatus for managing network resource consumption In various embodiments, excessive resource consumption within a network such as a Long Term Evolution (LTE) wireless network attributed to one or more user devices (UDs) is constrained by adjusting a Policy Control and Charging (PCC) rule associated with a network element serving the UD such that the corresponding network resource consumption level is reduced

Method and apparatus for managing mobile resource usage

There are provided a terminal apparatus, a base station apparatus, a method, and an integrated circuit for enabling the base station apparatus and the terminal apparatus to efficiently perform received power measurement in a communication system in which the base station apparatus and the terminal apparatus perform communication with each other. The terminal apparatus that performs the communication with the base station apparatus includes a reception circuitry that performs received power measurement that is based on a first signal, and the reception circuitry that performs the received power measurement that is based on a second signal in a case where information relating to a configuration of the second signal is notified by a higher layer. Furthermore, the reception circuitry performs the received power measurement that is based on a third signal in a case where information relating to a configuration of the third signal is notified.

A cluster-based, delegated software upgrade scheme facilitates software upgrade for radio base station nodes comprising a cluster of a flat radio access telecommunications network. The plural radio base stations (70) are grouped into clusters (30), and a master radio base station (RBSM) designated for each cluster. The master radio base station (RBSM) is used to initiate software upgrade of the radio base stations comprising the cluster. The master radio base station (RBSM) can also perform a monitoring of implementation of the software upgrade at the radio base stations of the cluster, and on the basis of the monitoring, determine whether a cluster- wide software upgrade is successful. In one of its example modes, the master radio base station can further prepare a software upgrade report which confirms/summarizes implementation of the software upgrade at the radio base stations of the cluster.

Upgrading software in radio base station nodes

Nodes such as base stations in a mobile communication network are divided and grouped into management clusters. One of the nodes in each management cluster is selected to be a master node. The master node aggregates performance data for each of the nodes in its assigned cluster, and sends a consolidated performance management report containing the aggregated data to a management entity.

A method and apparatus for collecting performance management data in communication networks

In a cellular wireless communications network, measurements are received from a plurality of user equipments relating to the reference signal received powers from a plurality of other cells of the cellular wireless communications network For other cells of the cellular wireless communications network having a physical cell identity (such as a scrambling code) that is the same as a physical cell identity of that first cell, it is determined from the received measurements whether a mutual potential interference level with that cell exceeds a threshold If so, an alternative physical cell identity is proposed, that would cause a mutual potential interference level between the cell or the potentially interfering cell and another cell already using that alternative physical cell identity that is lower than the mutual potential interference level between the cell and the potentially interfering cell.

Using the COMPA autonomous architecture for mobile network security

A method for predicting operational lifetime of a node in a communication network is disclosed. The method comprises obtaining an expected operational lifetime for the node ( 22 ), monitoring at least one of hardware identification data, operational data or operating environment data for the node ( 24 ), obtaining historical failure data for a subset of nodes in the communication network having monitored data corresponding to the monitored data of the node ( 26 ) and adjusting the expected operational lifetime for the node according to the obtained historical failure data ( 28 ). Also disclosed are a computer program product for carrying out the above method and a network element ( 500, 600 ) configured to carry out the above method.
