	This system could also be extended to monitor general actions. Consider again this set of observers, however, now they connect at random to various websites, and take a snapshot of all connections to it. At any given time, no other user knows which system the observers will be monitoring. In other words, the observers are analogous to police patrols, albeit with no set patrol route.

	Service Level Agreements (SLA) are needed to allow business interactions to rely on Internet services. Service Level Objectives (SLO) specify the committed performance level of a service. Thus, SLA compliance auditing aims at verifying these commitments. Since SLOs for various application services and end-to-end performance definitions vary largely, automated auditing of SLA compliances poses the challenge to an auditing framework. Moreover, end-to-end performance data are potentially large for a provider with many customers. Therefore, this paper presents a scalable and highly reusable auditing framework and a prototype, termed AURIC (Auditing Framework for Internet Services), whose components can be distributed across different domains.

	Abstract: This paper provides an overview of service-level agreements in IP networks. It looks at the typical components of a service-level agreement, and identifies three common approaches that are used to satisfy service level agreements in IP networks. The implications of using the approaches in the context of a network service provider, a hosting service provider, and an enterprise are examined. While most providers currently offer a static insurance approach towards supporting service level agreements, the schemes that can lead to more dynamic approaches are identified.

	We present a generic Service Level Agreement (SLA)-driven service provisioning architecture, which enables dynamic and flexible bandwidth reservation schemes on a per- user or a per-application basis. Various session level SLA negotiation schemes involving bandwidth allocation, service start time and service duration parameters are introduced and analysed. The results show that these negotiation schemes can be utilised for the benefits of both end user and network provide such as getting the highest individual SLA optimisation in terms of Quality of Service (QoS) and price. A prototype based on an industrial agent platform has also been built to demonstrate the negotiation scenario and this is presented and discussed.

	Service Level Agreements (SLAs) are used in Service-Oriented Computing to define the obligations of the parties involved in a transaction. SLAs define the service users’ Quality of Service (QoS) requirements that the service provider should satisfy. Requirements defined once may not be satisfiable when the context of the web services changes (e.g., when requirements or resource availability changes). Changes in the context can make SLAs obsolete, making SLA revision necessary. We propose a method to autonomously monitor the services’ context, and adapt SLAs to avoid obsolescence thereof.

	In a PCU, the VC management is implemented in two phases: the ﬁrst is an off-line phase of creating a VC that selects the appropriate resources and allocates them for the particular service; and the second phase employs on-line scheduling heuristic to distribute the jobs/requests from the APs among the VC nodes to achieve load balancing. A detailed simulation study is conducted to analyze the performance of different VC conﬁgurations for different load conditions and scheduling schemes and this performance is compared with a fully dynamic resource allocation scheme called Service Grid. The results verify the novelty of the VC concept.
