TL;DR: In this article, a method for managing the quality of service that applies to a packet mode mobile communications network, in particular, characterised in that it includes, in the case of a network overload when accessing the resources of the network in order to execute a service for a network subscriber, a stage that consists in the following, at the level of each node: determining an overall priority level for said access to resources, defined by a combination of at least one quality-of-service parameter related to the type of service and a subscriber priority level.
Abstract: The invention relates to a method for managing the quality of service that applies to a packet mode mobile communications network, in particular, characterised in that it includes, in the case of a network overload when accessing the resources of the network in order to execute a service for a network subscriber, a stage that consists in the following, at the level of each of the network nodes: determining an overall priority level for said access to resources, defined by a combination of at least one quality of service parameter related to the type of service and at least one quality of service parameter corresponding to the subscriber priority level, and applying at least one predefined quality of service process to the data stream that corresponds to said service, according to said determined overall priority level.

TL;DR: A framework for dynamic service bundling, which focuses on the exchange of valuable outcomes between customers and service suppliers, based on three components: a customer, a broker and a pool of suppliers is presented.
Abstract: In this paper we present a framework for dynamic service bundling, which focuses on the exchange of valuable outcomes between customers and service suppliers. The approach is based on three components: A customer, a broker and a pool of suppliers. The broker is in charge of matching the customer and supplier perspectives and performing a cluster-based bundling process. The applicability of our approach is proven by means of a case study in the educational service industry.

TL;DR: In this article, the authors propose a service discovery mechanism that allows a client to request a capability credential from a service and the service may then respond with the capability credential that may convey to the client the rights to use the requested capabilities.
Abstract: A service discovery mechanism may allow clients in a distributed computing environment to search for services. The service discovery mechanism may allow a client to request a capability credential from a service. The distributed computing environment may include a mechanism for a client to negotiate service access rights and to then obtain a capability credential that may be used to obtain the service's access interface to the set or subset of the service's capabilities that were requested or negotiated by the client. In one embodiment, the client may present to the service a set of desired capabilities. The service may then respond with a capability credential that may convey to the client the rights to use the requested capabilities. A complete service advertisement may be needed to create a message endpoint for accessing the service. In an embodiment, the capability credential may be used by a client to obtain a complete advertisement for only the requested or negotiated capabilities. The capability credential may provide an additional level of security for the service provider. The capability credential that may be used to receive the complete advertisement may also be used to construct a message gate to communicate with the service where the gate embeds the capability credential in each message to the service.

TL;DR: Finite State Machine (FSM) is used to prescribe the legal invocation orders of these web services, also an improved Tree-pruning-based algorithm is proposed to create the Web Service Composition Tree (WSCT) and an experiment is presented for validating the performance.
Abstract: Many recent studies have been addressing the service selection problem based on non-functional aspects due to the ever-increasing number of web services. However, most existing works about QoS-based service composition treat the services referred in service composition as independent ones from each other, and their correlations are usually ignored. In reality, the services supplied by service providers in cloud environment are not segregate and irrelevant with each other. In view of this challenging problem, we use Finite State Machine (FSM) to prescribe the legal invocation orders of these web services, also an improved Tree-pruning-based algorithm is proposed to create the Web Service Composition Tree (WSCT). After generating all of the feasible execution paths, a Simple Additive Weighting (SAW) technique is used to select an optimal one. At last, an experiment is presented for validating the performance of the method.

TL;DR: A model to generate service level agreement on-the-fly based on a quality model that supports both users requirements and providers capabilities definition is proposed.
Abstract: Before a service invocation takes place, an agreement between the service provider and the service user might be required. Such an agreement is the result of a negotiation process between the two parties and defines how the service invocation has to occur. Considering the Service Oriented Computing paradigm, the relationship among providers and users is extremely loose. Traditional agreements are likely to concern long term relationships and to be manually performed. In this paper, we propose a model to generate service level agreement on-the-fly. Just before the invocation commences, the quality of the service is negotiated in order to generate a service level agreement tied to that specific invocation. Such an approach relies on a quality model that supports both users requirements and providers capabilities definition.
