20090116404 | TOPOLOGY DISCOVERY IN HETEROGENEOUS NETWORKS - A Next Generation Network (NGN) resource management system and method includes a network topology discovery mechanism at the scale of an administrative domain. Information about nodes and links, such as bandwidth, delay, jitter, name and description of devices is collected and stored in a database by way of a protocol. The protocol is notifications-based, which involves each node device (e.g., a switch, router etc.) notifying its presence to its neighboring node. | 05-07-2009 |
20090161541 | RESOURCE ALLOCATION PLAN IN A NETWORK - A method and Resource Allocation Manager Entity for obtaining an improved resource allocation plan for the network. Traffic requests currently exist in a network, each of which having a source, a destination and at least one Quality of Service (QoS) requirement being represented by a QoS value. For each traffic request, at least one potential path consisting of a plurality of links is computed. An iteration matrix is generated having the potential path on first axis, the links on second axis and the QoS requirement on third axis. The iteration matrix is filled by, for each of potential path, distributing the QoS value of the QoS requirement over the links for enabling a gradient space calculation method on the iteration matrix. The gradient space calculation method is applied to the iteration matrix until an iteration marker thereof indicates that the iteration matrix contains the improved resource allocation plan. | 06-25-2009 |
20100014455 | ACCESS NETWORK SELECTION - A network, computer readable medium, and method for ranking a plurality of available access networks by a provider, the provider serving a user equipment and the user equipment being configured to connect to at least one of the plurality of available access networks. The method includes receiving a selection request at a selection entity of the provider, where the selection request includes a vector parameter P that includes required characteristics of a data flow for the user equipment, sending from the selection entity a capability request, including the vector parameter P, to the plurality of available access networks, receiving at the selection entity a capability response from the plurality of available access networks, wherein each capability response includes a normalized value expressing a capability of a corresponding available access network to provide the required characteristics of the data flow, and generating a ranking list of the available access networks based on the received normalized values. | 01-21-2010 |
20100138816 | MULTIMEDIA SERVICE COMPOSITION FACTORY - Systems and methods for the creation and deployment of services on a converged network are described herein. These services can be initially created from visual constructs and have their life cycle performed and monitored by a multimedia service composition factory. Functions for design, implementation, installation, verification and coordination can be provided to compose services after pre-compiled code segments are received from a user interface. | 06-03-2010 |
20110131307 | METHOD AND NODE FOR APPLYING A POLICY TO A SESSION BASED ON A PREVIOUSLY PREDICTED SESSION STATE - A method and a policy enforcement point are provided for applying policies to a session. An eventual state of the session is predicted in a prediction engine of a policy enforcement point. The predicted state is sent to a policy controller, which returns a policy for the predicted state. If the predicted state, or a similar state, is detected, the policy enforcement point applies the policy for the predicted state to the session. | 06-02-2011 |
20120320743 | Devices and Methods for Managing Quality of Service for Bearers Depending on Utilization - Methods and devices used for a dynamic QoS management taking into consideration a global throughput and individual bearer throughputs are provided. The global throughput and individual bearer throughputs may be predicted upon receiving each packet from a public domain network. Individually, for each bearer is determined if a current QoS service is adequate by comparing the global throughput with threshold values associated to the bearer and on evaluating whether the bearer is overloaded. If the current QoS level associated with the bearer is not adequate, the QoS level associated with the bearer is set to another QoS level. | 12-20-2012 |
20130058227 | SYSTEM AND METHOD OF BUILDING AN INFRASTRUCTURE FOR A VIRTUAL NETWORK - A network resource module communicatively interfaces a resource manager with one or more network nodes in a communications network. Each network node provides one or more network resources that may be used to create a virtual infrastructure for a virtual network. The network resource module detects the network nodes, abstracts the resources associated with the network nodes at a desired granularity (e.g., node level or flow level) into Virtual Resource Objects (VROs), and then publishes the VROs in a registry. Thereafter, Virtual Network Operators (VROs) select desired VROs from the registry to build the virtual infrastructure for the virtual network. | 03-07-2013 |
20140022951 | LOGICAL INTER-CLOUD DISPATCHER - Embodiments of the present invention provide a method and system for establishing a network communication path between a source node and a destination node. A destination geographic area of the destination node is determined. An intermediate node located in an intermediate geographic area that is adjacent to a source geographic area of the source node and is in a direction that is toward the destination geographic area is determined based at least in part on the destination geographic area. Connectivity with the intermediate node is requested or established. A determination is made as to whether the adjacent intermediate geographic area is the destination geographic area. If the determined adjacent intermediate geographic area is not the destination geographic area, a next intermediate node in another intermediate geographic area that is adjacent to the intermediate geographic area and is in a direction that is toward the destination geographic area is determined. | 01-23-2014 |
20140245077 | PROVIDING HIGH AVAILABILITY FOR STATE-AWARE APPLICATIONS - A middleware that manages high availability of a software application is automatically configured when the software application is added to a system. The method of automatic configuration includes receiving a user input that specifies availability requirements and information of the software application, where the availability requirements include at least a checkpoint service that enables the software application to save and retrieve its state. The method also includes identifying a checkpoint agent for providing the checkpoint service to the software application. The checkpoint agent includes a first interface to the software application and a second interface, different from the first interface, to the middleware. A middleware configuration is generated that satisfies the availability requirements, based on the information of the software application such that the middleware offers the checkpoint service to the software application through the checkpoint agent and directly manages lifecycles of the software application. | 08-28-2014 |
