Handling SLA Violations via Constraint Imperative Programming

2013
The handling of violations of Service Level Agreement (SLA) is important for trustful service, particularly for web services in business field. In this paper, a SLA specification combines syntactic constructs from WS-Agreement and WSLA is proposed.

What Are the Chances an Availability SLA will be Violated?

Sixth International Conference on Networking (ICN'07), 2007
There is danger in coming to important conclusions based on averages, as insights into spread are not provided by this single measure. When promises are made about availability this is a "mean". Knowledge of availability probabilistic distribution is paramount in understanding what is being offered and what is being bought, as the chance an ...

Monitoring, Prediction and Prevention of SLA Violations in Composite Services

2010 IEEE International Conference on Web Services, 2010
We propose the PREvent framework, which is a system that integrates event-based monitoring, prediction of SLA violations using machine learning techniques, and automated runtime prevention of those violations by triggering adaptation actions in service compositions.

Trustworthy Detection and Arbitration of SLA Violations in the Cloud

2018
In cloud computing, detecting violations of Service Level Agreements (SLAs) is possible by measuring certain metrics, which can be done by both the provider and the consumer of a service. However, both parties have contradicting interests with regards to these measurements, which makes it difficult to reach consensus about whether SLA violations have ...

Service Level Agreement Violation Detection in Multi-cloud Environment using Ethereum Blockchain

2023 International Conference on Networking and Communications (ICNWC), 2023
With the advancement of cloud computing technologies, it is necessary to maintain quality of service, for which service level agreements (SLAs) are one of the ways to improve this. A significant part of revenue will be contributed by the use of on demand

Detection of Service Level Agreement (SLA) Violations in Memory Management in Virtual Machines

2015 24th International Conference on Computer Communication and Networks (ICCCN), 2015
In cloud computing, quality of services is often enforced through Service Level Agreement (SLA) between end users and cloud providers. While SLAs on hardware resources such as CPU cycles or bandwidth can be monitored by low layer sensors, the enforcement of security SLAs stays a very challenging problem.

Live Data Migration for Reducing SLA Violations in Multi-tiered Storage Systems

2014 IEEE International Conference on Cloud Engineering, 2014
Today, the volume of data in the world has been tremendously increased. Large-scaled and diverse data sets are raising new big challenges of storage, process, and query. Tiered storage architectures combining solid-state drives (SSDs) with hard disk drives (HDDs), become attractive in enterprise data centers for achieving high performance and large ...

O-RAN-Enabled Intelligent Network Slicing to Meet Service-Level Agreement (SLA)

IEEE Transactions on Mobile Computing
Network slicing plays a critical role in enabling multiple virtualized and independent network services to be created on top of a common physical network infrastructure. In this paper, we introduce a deep reinforcement learning (DRL)-based radio resource
