Technologies for independent service level agreement monitoring

Abstract: Technologies for monitoring service level agreement (SLA) performance in an end-to-end SLA monitoring architecture include a network functions virtualization (NFV) SLA controller configured to manage SLA agents initialized in various network processing components of the end-to-end SLA monitoring architecture. To do so, the NFV SLA controller is configured to provide instruction to the SLA agents indicating which types of telemetry data to monitor and receive the requested telemetry data, as securely collected and securely packaged by the SLA agents. The NFV SLA controller is further configured to securely analyze the received telemetry data to determine one or more performance metrics and compare performance benchmarks against the performance metrics to generate an SLA report that includes the results of the comparison. Other embodiments are described and claimed.

Dynamic e-Maintenance in the era of SOA-ready device dominated industrial environments

Abstract: The factory of the future will be heavily based on service oriented architecture approaches. Business continuity will need to be guaranteed as interactions in the shop-floor will be more complex and demanding. In parallel sustainable manufacturing is emerging as a new approach to address economical, environmental, and societal issues. In this context, maintenance will play a major role. In particular, an e-maintenance platform will have to deal with the emerging challenges, and take advantage not only of the latest technologies but also of new collaborative concepts that will be possible in the future factory. We discuss here the dynamic e-Maintenance in the era of SOA-ready device dominated industrial environments. Furthermore, we demonstrate how existing efforts in cross-layer SOA based enterprises in conjunction with e-maintenance platform can greatly enhance existing decision making processes supporting the transition towards sustainable manufacturing.

An architecture design of life cycle based SLA management

Abstract: In the Web services environment, appropriate guarantee for the service quality can maximize the ability of web services and ensure the services to be carried out effectively and controllable, and that's what SLA contracts can offer An SLA(service level agreement) is a contract agreed between a service client and a service provider which defines a series of service quality characters and metrics‥ In SLA management , the SLA life cycle should be considered carefully because the SLA life cycle is special that includes some issues that out of the service runtime environment, so a common web service management architecture will not meet the SLA management requirements It is needed to divide the management functions base on the SLA life cycle Thus, in this paper, the life cycle of SLA is discussed and the SLA-supported Web service architecture and management requirements are also presented An SLA management platform is designed for SLA definition, service SLA registration and run-time SLA monitoring and controlling mainly base on the SLA life cycle The paper furthermore shows a model for the mapping from SLA parameters which are advertised by service providers to QoS parameters which are required by service clients

Service metrics for managing services transported over circuit-oriented and connectionless networks

Abstract: Described are a system and method for managing a service transported over a transport network between first and second service termination points. Packet traffic associated with the service is received at a service termination point connected to the transport network. Performance of the packet traffic is measured at the service termination point. The measured performance of the packet traffic and the service are correlated to produce a performance of service (PoS) service metric. Based on the PoS service metric, other service metrics associated with the service are correlated, including a rate of service (RoS) service metric and availability of service (AoS) service metric. These service metrics can be used to develop service level agreement (SLA) and service level metrics that define the operation of the service and operation of the network supporting those services.

SDN based architecture for QoS enabled services across networks with dynamic service level agreement

Abstract: Nowadays QoS enabled real time services are demanding and dominating over Internet. However, providing end-to-end QoS requirement across Internet is still a challenge. With changing challenges and demands, service providers should be able to implement their strategic and business policies dynamically. Therefore current Internet architecture needs a change to support the present and future requirements, as well as any new innovation for better performance. The advent of Software Defined Network (SDN) is giving an opportunity to rethink and experiment with new innovations for Networking. In this paper we analyze current problems of Internet and propose a novel architecture and algorithm to address QoS across Internet with open opportunity for future enhancements by introducing dynamic relationship among service providing entities. Our simulation results reveal that proposed SDN architecture dealing with interactions among Internet service providers with dynamic Service Level Agreement (SLA) is advantageous for QoS enabled applications than the current architecture.
