摘要： An Availability Management Framework (AMF) configuration describes how configuration entities of a highly available system are grouped and includes information on service provision and service protection policies against resource failure. The AMF configuration defines a set of failure types for each component and each node, and specifies a failure rate and a recommended recovery for each failure type. A method for evaluating service availability receives the AMF configuration as input, and analyzes it to obtain an actual recovery that the highly available system is to perform when the given component fails. The method maps the AMF configuration to a stochastic model that captures the dependencies among the components and among the configuration entities at multiple levels of the hierarchy. The method utilizes the model to calculate the service availability of the AMF configuration based on the failure rate, the actual recovery and the dependencies.
摘要翻译：可用性管理框架（AMF）配置描述了高可用性系统的配置实体如何分组，并包含有关资源故障的服务提供和服务保护策略的信息。 AMF配置为每个组件和每个节点定义一组故障类型，并为每种故障类型指定故障率和建议恢复。用于评估服务可用性的方法接收AMF配置作为输入，并分析它以获得当给定组件发生故障时高可用性系统要执行的实际恢复。该方法将AMF配置映射到捕获组件之间的依赖关系以及层次结构中多个级别的配置实体之间的随机模型。该方法利用该模型根据故障率，实际恢复和依赖关系计算AMF配置的服务可用性。

摘要： Redundancy models are compared to determine or assist in determining an Availability Management Framework (AMF) configuration of a highly available system based on quantified service availability of the system. Each redundancy model defines assignments of service-instances to service-units. An analysis model of the system is constructed to capture recovery behaviors of the system for each redundancy model. Service availability of the system is quantified based on the analysis model under one or more scenarios including failure scenarios and recovery scenarios. Based on a comparison of service availability levels provided by the redundancy models and subject to constraints of the HA system, one of the redundancy models is identified that provides a required level of service availability for the system.

摘要： Among other things, embodiments described herein enable systems, e.g., Availability Management Forum (AMF) systems, having service units to operate with balanced loads both before and after the failure of one of the service units. A configuration can be generated which provides for distributed backup roles and balanced active loads. When a failure of a service unit occurs, the active loads previously handled by that service unit are substantially evenly picked up as active loads by remaining service units.

摘要： There is provided a method for applying a penalty to a cloud service provider, while upgrading resources in a system providing infrastructure-as-a-service (IaaS), for improved maintenance of resources according to a service level agreement (SLA), comprising iteratively: detecting a change in a number of expected resources or a number of provided resources; and upon determining that a previous unavailability event was ongoing, calculating the penalty for the previous unavailability event using a quadratic proportional function. The method also comprises computing a total penalty as the sum of the penalties for each previous unavailability event; and applying the total penalty to the cloud service provider of the IaaS. There is provided a method and network node for upgrading resources in a system based on dependencies and service level agreement (SLA) requirement including a penalty for outage of the resources, wherein calculating the penalty comprises using the quadratic proportional function.

摘要： A Network Service Descriptor (NSD) is generated, from Virtualized Network Functions (VNFs) existing in a VNF catalog, for instantiating a network service which satisfies given network service requirements. From the VNF catalog, a system selects VNFs that provide functionalities and architectural blocks required to fulfill the NS requirements. The system generates at least a VNF forwarding graph (VNFFG), which includes relations between the functionalities and the architectural blocks of the selected VNFs as well as traffic flows between the selected VNFs. The system then creates the NSD, which includes the VNFFG, for instantiating the network service.

摘要： A monitoring engine includes a monitoring server and a set of monitoring clients is adapted to measure the workload of a service in a system managed by Availability Management Framework (AMF). The system includes one or more components that receive component service instance (CSI) assignments for the service. Each monitoring client runs on a node in the system and is adapted to detect, at runtime, an assignment of a CSI of the service to a component to obtain information identifying the assignment, and to obtain a system resource usage of the component resulting from the assignment based on the information. The monitoring server is adapted to receive the system resource usage attributable to the service from the set of monitoring clients, and to aggregate the system resource usage to obtain the workload of the service.
