“…Approaches at defining SLAs in machine interpretable formats have enabled the dynamic interpretation and evaluation of SLAs (see [30] for a comparison of formats). However there has been little progress in the field of automated or dynamic negotiation of SLAs outside of the field of cloud or grid computing [19,39].…”

Federation Lifecycle Management Incorporating Coordination of Bio-inspired Self-management Processes

As it has evolved, the Internet has had to support a broadening range of networking technologies, business models and user interaction modes. Researchers and industry practitioners have realised that this trend necessitates a fundamental rethinking of approaches to network and service management. This has spurred significant research efforts towards developing autonomic network management solutions incorporating distributed self-management processes inspired by biological systems. Whilst significant advances have been made, most solutions focus on management of single network domains and the optimisation of specific management or control processes therein. In this paper we argue that a networking infrastructure providing a myriad of loosely coupled services must inherently support federation of network domains and facilitate coordination of the operation of various management processes for mutual benefit. To this end, we outline a framework for federated management that facilitates the coordination of the behaviour of bio-inspired management processes. Using a case study relating to distribution of IPTV content, we describe how Federal Relationship Managers realising our layered model of management federations can communicate to manage service provision across multiple application/storage/network providers. We outline an illustrative example in which storage providers are dynamically added to a federation to accommodate demand spikes, with appropriate content being migrated to those providers servers under control of a bio-inspired replication process.

“…It consists of an XML-based language for specifying SLAs, as well as a protocol for negotiating its terms [22]. Hudert et al extended these ideas with a framework built around WSAgreement that supports multilateral in addition to bilateral negotiations [23]. Hasselmeyer et al proposed a Discrete-Offer-Protocol that allows the service provider to make a single offer, which the consumer can accept or reject [24].…”

End-to-End Resource Management for Federated Delivery of Multimedia Services

et al. 2013

Recently, the Internet has become a popular platform for the delivery of multimedia content. Currently, multimedia services are either offered by Over-the-top (OTT) providers or by access ISPs over a managed IP network. As OTT providers offer their content across the best-effort Internet, they cannot offer any Quality of Service (QoS) guarantees to their users. On the other hand, users of managed multimedia services are limited to the relatively small selection of content offered by their own ISP. This article presents a framework that combines the advantages of both existing approaches, by dynamically setting up federations between the stakeholders involved in the content delivery process. Specifically, the framework provides an automated mechanism to set up end-to-end federations for QoSaware delivery of multimedia content across the Internet. QoS contracts are automatically negotiated between the content provider, its customers, and the intermediary network domains. Additionally, a federated resource reservation algorithm is presented, which allows the framework to identify the optimal set of stakeholders and resources to include within a federation. Its goal is to minimize delivery costs for the content provider, while satisfying customer QoS requirements. Moreover, the presented framework allows intermediary storage sites to be included in these federations, supporting on-the-fly deployment of content caches along the delivery paths. The algorithm was thoroughly evaluated in order to validate our approach and assess the merits of including intermediary storage sites. The results clearly show the benefits of our method, with delivery cost reductions of up to 80% in the evaluated scenario.

“…The ISQoS Grid architecture is service oriented and is WS-Agreement for Java (WSAG4J) [15] based and presents services to execute jobs. Avoiding classical architectures such as Globus [12] has allowed the focus upon scheduling and the ability to negotiate service level agreements (SLAs).…”

Abstract. We introduce our Grid broker that uses SLAs in job submission with the aim of ensuring jobs are computed on time and on budget. We demonstrate our broker's ability to perform negotiation and to select preferentially higher priority jobs, in a tender market and discuss the architecture that makes this possible. We additionally show the effects of rescheduling and how careful consideration is required in order to avoid price instability. We therefore make recommendations upon how to maintain this stability, given rescheduling.
