  • Publication number: 20200293418
    Abstract: Embodiments herein relate to a method performed by a network node (10) for handling monitoring of applications and/or services in a communication network. The network node (10) obtains an indication associated with a monitoring session to monitor a metric of a service and/or application; and also obtains a location of deployment of the service and/or application. The network node identifies one or more ongoing monitoring sessions for monitoring one or more metrics based on the metric associated with the indication and the location of deployment of the application or service. The network node (10) then selects a monitoring process based on the identification; and triggers the selected monitoring process.

  • Publication number: 20200137152
    Abstract: A method and a communication device for determining a score relating to a first agent module are described. The communication device receives information relating to at least one request, performed by another agent module separate from the first agent module, for consumption of a capability of the first agent module. The information relating to the at least one request includes information about the capability of the first agent module, information about an intention of the first agent module, and information about a policy for the capability. The communication device calculates the score in relation to the first agent module based on the information relating to the at least one request, wherein the score further is specified with respect to the capability.

  • Patent number: 10469343
    Abstract: Mechanisms for path continuity determination in an aggregate flow environment. An ingress node and a downstream node for which a path continuity check is desired are determined. The ingress node devolves, from an aggregate flow entry, one or more microflows that comprise packets which are destined for the downstream node. The downstream node is directed to generate corresponding microflows. Each microflow is associated with a continuity set identifier and has one or more timers, such as an idle timer and/or a hard timeout timer. Upon timeout of one of the timers, the ingress node and the downstream node send a microflow termination message that contains the continuity set identifier to a controller node. The controller node determines a path continuity status between the ingress node and the downstream node based on a receipt of one or more microflow termination messages from the ingress node and the downstream node.

  • Publication number: 20140229928
    Abstract: A method of upgrading a software package having a first revision level on a production node includes providing a virtual node, installing the software package on the virtual node, copying configuration data from the production node to the virtual node, upgrading the software package on the virtual node to a second revision level, redirecting a portion of traffic associated with the software package from the production node to the virtual node, and determining if the virtual node correctly handles the redirected portion of traffic.

  • Patent number: 7697490
    Abstract: A cluster of terminals, and an ad-hoc network of two or more such clusters, for carrying a multi-party, cluster-based, conference, wherein each cluster includes a super member comprising a super user agent, and one or more members including a user agent. Communications sessions are established between the super member of each cluster and each member terminals of the same cluster, and between the super members of each one of the first and second clusters. The user agent comprises identity of the super member, a conference identity, cluster parameters including a split value (Sv) indicative of a maximum number of terminals that may be part of the cluster, wherein when Sv is reached during the conference the cluster is split, and a merge value (Mv) indicative of a minimum number of terminals that may be part of the cluster, wherein when Mv is reached the cluster is merged with another cluster.

  • Patent number: 7460508
    Abstract: Methods for establishing a cluster-based multi-party conference and for carrying on the conference as participants join or leave the conference are provided. First, two or more terminals participating to the conference are joined in a cluster, wherein one of them is elected as a super member of the cluster. The other terminal is updated with the identity of the super member terminal, the identification of the conference, and with cluster parameters including a split value Sv indicative of a maximum number of terminals that may be part of the cluster, wherein when the split value Sv is reached during the conference, the cluster is split; and a merge value Mv indicative of a minimum number of terminals that may be part of the cluster, wherein when the merge value Mv is reached during the conference, the cluster is merged with another cluster. A method for splitting the cluster, and a method for merging two clusters are also provided.

  • Publication number: 20070109979
    Abstract: A method and conference controller for cluster-based conferencing between ad-hoc network terminals supporting cluster-based conferences and legacy network terminals not equipped with such capabilities. The controller implements a Super User Agent (SUA) having a conference identity, a cluster member list including identities of legacy network's terminals members of a cluster of terminals of the legacy network participating to the conference, and a cluster neighbour list that identifies terminals from an ad-hoc network that act as a super member of a cluster of terminals of the ad-hoc network.

  • Publication number: 20060114847
    Abstract: A user agent and a super user agent for use in terminals for cluster-based multi-party conferencing using one or more clusters of terminals. Each cluster includes a super member comprising a super user agent, and one or more members including a user agent. The user agent comprises identity of the super member terminal of the cluster, a conference identity identifying the cluster-based conference, cluster parameters including a split value (Sv) indicative of a maximum number of terminals that may be part of the cluster, wherein when Sv is reached during the conference the cluster is split, and a merge value (Mv) indicative of a minimum number of terminals that may be part of the cluster, wherein when Mv is reached the cluster is merged with another cluster.
