TL;DR: In this paper, the authors proposed a new paradigm for a Differentiated Service (DiffServ) network consisting of two-color marking at the edges of the network using token buckets coupled with differential treatment in the core.
Abstract: In this paper we propose a new paradigm for a Differentiated Service (DiffServ) network consisting of two-color marking at the edges of the network using token buckets coupled with differential treatment in the core. Using fluid-flow modelling, we present existence conditions for token-bucket rates and differential marking probabilities at the core that result in all edges receiving at least their minimum guaranteed rates. We then present an integrated DiffServ architecture comprising of an active rate management controller at the marking edge and a two-level active queue management controller at the core. The validity of the fluid flow model and performance of this new scheme are verified using ns simulations.

TL;DR: A novel concept, called service skyline, and a set of service skyline computation techniques that return aset of most interesting service providers that are non-dominant in all user interested quality attributes are developed.
Abstract: As multiple service providers may compete to offer the same functionality with different quality of service (e.g., latency, fee, and reputation), a key issue in service computing is selecting service providers with the best user desired quality. Existing service selection approaches mostly rely on computing a predefined objective function. When multiple quality criteria are considered, users are required to express their preference over different (and sometimes conflicting) quality attributes as numeric weights. This is a rather demanding task and an imprecise specification of the weights could miss user desired services. We propose a multi-attribute optimization approach to tackle this issue. In particular, we develop a novel concept, called service skyline, and a set of service skyline computation techniques that return a set of most interesting service providers. These providers are non-dominant in all user interested quality attributes. Thus, the service skyline ensures that the user desired providers will be included. Analytical and experimental studies justify the performance of the proposed techniques. The relative small sizes of the service skylines also make it practical for service users to make selections from them.

TL;DR: The proposed approach facilitates rapid development and provisioning of composite services by specifying what to compose in a constraint-hierarchy based way using VCL (Vienna Composition Language) and upon success the newly composed service is immediately deployed and available.
Abstract: Software as a Service (SaaS) and the possibility to compose Web services provisioned over the Internet are important assets for a service-oriented architecture (SOA) However, the complexity and time for developing and provisioning a composite service is very high and it is generally an error-prone task In this paper we address these issues by describing a semi-automated "Composition as a Service'' (CaaS) approach combined with a domain-specific language called VCL (Vienna Composition Language) The proposed approach facilitates rapid development and provisioning of composite services by specifying what to compose in a constraint-hierarchy based way using VCL Invoking the composition service triggers the composition process and upon success the newly composed service is immediately deployed and available This solution requires no client-side composition infrastructure because it is transparently encapsulated in the CaaS infrastructure

TL;DR: In this paper, the authors propose a membership model that allows a first on-line service entity having its own membership model to efficiently collaborate with a second online service entity to offer its users the services of the second online services entity in a seamless and consistently branded manner.
Abstract: Methods, apparatuses and systems facilitating integration of the functionality associated with a first on-line service entity with the functionality associated with a second on-line service entity. Embodiments of the present invention allow a first on-line service entity having its own membership model to efficiently collaborate with a second on-line service entity to offer its users the services of the second on-line service entity in a seamless and consistently branded manner. One implementation obviates the need for synchronization of the membership models between the first and second on-line service entities. One implementation allows the second on-line service entity to provide services to the users associated with the first on-line service entity in a seamless manner without the first on-line service entity having to proxy the session between the second on-line service entity and the users.

TL;DR: In this article, a base station and a wireless communication system are provided which allow to provide optimized quality of service to each of a plurality of services belonging to different QoS classes and different users, transmitted over shared physical channels.
Abstract: A method, a base station and a wireless communication system are provided which allow to provide optimized Quality of Service to each of a plurality of services belonging to different QoS classes and different users, transmitted over shared physical channels. Data packets are assigned to service categories. To each service category only packets are assigned exclusively belonging to services associated with one user or user group and exclusively belonging to one of said Quality of Service classes. Based on information about the packets, the service categories and/or the shared physical channels, scheduling metrics are calculated, based upon the scheduling metrics, it is decided which of said service categories is to be served next.
