Methods of assigning network service templates in a communication network including a plurality of network elements that are configured to implement a plurality of network services are provided. The methods include providing a plurality of network service templates for a first network service, providing a network service model for providing the first network service by at least one network element in the communication network, comparing the plurality of network service templates with the network service model, and associating at least one network service template with the network service model in response to the comparison.

A method of, and apparatus for, predicting the performance of a data storage resource forming part of a networked electronic data store. The method includes representing the data storage resource as a plurality of separate virtual storage components, each virtual storage component representing a part of the data storage resource and having at least one operational state selectable from a pool of operational states. The method further includes obtaining resource profile data from the data storage resource, and modelling the performance of the data storage resource by assigning, from the pool, an operational state to each virtual storage component to fit the resource profile data. By providing such a method, the data storage resource can be represented as a collection of virtual storage components, each having a dynamically-assignable operational state. This enables the modelling of the performance of the data storage resource to be simplified significantly because each virtual storage component can only have a finite number of operational states, simplifying the modelling of access patterns on, and interactions between, the virtual storage components.

Device Assisted Services (DAS) for protecting network capacity is provided. In some embodiments, DAS for protecting network capacity includes monitoring a network service usage activity of the communications device in network communication; classifying the network service usage activity for differential network access control for protecting network capacity; and associating the network service usage activity with a network service usage control policy based on a classification of the network service usage activity to facilitate differential network access control for protecting network capacity.

Domains (multiple collaborating service providers) create service offerings between pairs of edge nodes that interconnect with other domains in the network. The service offerings may specify the available bandwidth, quality of service, reliability, available security, price, subscriber and service contextual specific and other SLA information. When a new service is to be created, the service definition is used along with information about the available service offerings to determine a set of networks to implement the service. Information associated with the service offerings may be flooded to all other networks. Alternatively, the service offering information may be provided to a trusted third party (SLA broker) which may provide SLA services on the network to select sets of domains to implement inter-domain services, and may also proxy to set up the service for the SLA requesting party. A hybrid approach may also be used wherein some SLA information is flooded and other information is retained in secret and provided only to the SLA broker.

A logical customer organization model is applied to group the individual agreements into separate logical customer organizations, wherein the groupings can be region based groupings, organization groupings and departmental groupings. Unified login identification (ID) model is applied to enable a first user to login to a portal using a first login ID to access a first asset in a first asset group according to a first logical customer organization. The unified login ID model enables the first user to use the same first login ID to access a second asset in the first asset group according to the first logical customer organization. The unified login ID model also enables the first user to login to the portal using a second login ID to access one or more assets in a second asset group according to a second logical customer organization. Each of the first and second logical customer organization may be associated with one or more asset groups and one or more user groups.
摘要:
This disclosure provides a method and apparatus for normalizing service level agreements across entire networks. By utilizing a new parameter called the virtual call count, a wholesale network provider can monitor a variety of related network status indications and provide to their customers increased insight into the nature of the service level rejections that they experience. Existing service level agreement processors can be equipped with the additional functionality of calculating the virtual call count to form an apparatus for normalizing service level agreements.
摘要:
The present invention discloses a document for formally defining service level requirements in a service oriented architecture (SOA). This document can include a service specification that defines functional attributes and a capability specification that defines performance requirements. These functional attributes and performance requirements can influence the response of the SOA to a service request. For example, a dynamic interpreter of the requirements document can dynamically adjust SOA resources to ensure performance requirements specified in the requirements document are met.

The present invention comprises methods for increasing the rank of the routing matrix of an IP network by systematically altering link weights in the IP network. A full rank routing matrix may be used with further methods in accordance with the present invention to estimate the mean traffic of the IP network based upon the full rank routing matrix and measured link utilization values. The mean traffic and the covariance of the traffic may be iteratively estimated until the estimates coverage. Example methods in accordance with the present invention for estimating mean traffic and covariance of traffic are described for both stationary and non-stationary link utilization data.

Performance measurements for a network, such as delay, delay variation, and loss, are performed over layer-2. A PM frame is sent from a source MEP (Maintenance End Point) to a destination MEP. The PM frame is timestamped immediately prior to transmission, and the local clock at the destination MEP is noted immediately upon arrival. MIPs (Maintenance Intermediate Points) may also time stamp the PM frame. Preferably, each PM frame has an interval (session) identifier and a sequence number within the interval. The PM frames are received by and sent by PM modules within the nodes of the network. The PM modules include a Sender function for sending an interval of one or more PM frames and a Receiver function for receiving PM frames and computing measurements.
