“…Non-functional monitoring is concerned with the statistical QoS metrics collection to evaluate wheatear a provider complies with the QoS level specified in the SLA [31], [21]. Fundamental concepts of non-functional SLA monitoring are presented in [31] which contains a discussions on the separation of the computation and communication infrastructure of the provider, service points of presence and metric collection approaches. The authors propose an architecture for QoS monitoring by third parties to ensure that the results are trusted by both the provider and consumer.…”

Abstract-When having repeated interactions with a service provider, a service consumer might desire guarantees on the delivery of the service. These guarantees involve both functional and non-functional properties of the offered service over a number of invocations. When the guarantee terms are explicitly defined in a document, we talk about a service level agreement. WS-Agreement is an industry driven emerging protocol for the specification of agreements in the context of Web Services. If, on the one hand, WS-Agreement defines the XML syntax for the language and protocol, on the other hand, it gives only a vague textual overview of the intended meaning. We fill this gap by providing a formal definition of an agreement and analyzing the possible evolutions of agreements and their terms over an execution. As a result we identify a number of extensions which involve the initial negotiation, the monitoring of running agreements, and the possibility of renegotiating agreements in executions. We evaluate the proposed approach through experimentation.

“…In order to guarantee the performance of the services, the network performance has to be verified by performing network monitoring. Many monitoring architectures were proposed for intra-domain networks such as in [1] and [2] or proposed for multi-domain networks. A monitoring architecture can use standard monitoring protocols such as Real-time Traffic Flow Measurement (RTFM) [3], IP Flow Information eXport (IPFIX) [4], and Packet Sampling (PSAMP) [5].…”

Abstract-The monitoring of the quality of service in a multidomain network supervises the multi-domain service performance. A multi-domain service is a service that crosses several domains which can be managed by different providers. Since each domain can be managed with its own policies and may require confidentiality of its topology and its monitoring processes, we propose that the monitoring architecture has to be configurable. In this paper, we propose two collaboration schemes that are based on the reactive and the proactive modes. Both of collaboration schemes allow the multi-domain monitoring architecture to select the measurement points that will participate in the multi-domain monitoring and to configure the selected measurement points. In this paper, we present our proposed collaboration schemes and then we evaluate their performance through extensive simulations using Network Simulator (NS-2).

Abstract-In Internet networks, monitoring is necessary to guarantee the performance of the services. In this paper, we review the state-of-the-art monitoring architectures proposed for multi-domain networks. We note that these architectures do not support measurement configuration that enables the providers to perform flexible multi-domain measurements. Therefore, we present our proposal for the configuration of the multi-domain network monitoring architecture in order to give more flexibility in network monitoring and solve the heterogeneity and interoperability problems. We also present our collaboration schemes that can be applied in our configurable monitoring architecture. These collaboration schemes, based on the proactive selection and reactive selection, are used to select the measurement points that participate in the multi-domain monitoring and configure the parameters of the measurement points selected. We show through extensive simulations that the proactive collaboration scheme provides a more flexible multi-domain monitoring and reduces the delay and the overload of the monitoring establishment.
