Today, various stakeholders provide a large number of functionally similarWeb Services (WS) to meet increasingly complex business needs. Therefore, distinguish similar WS, some researchers have proposed using the non-functional characteristics, named Quality Service (QoS), and user’s needs, expressed through Experience (QoE). Thus, all those QoS QoE attributes should be taken into account in pr...

We describe a framework for providing quality-of-service (QoS) guarantees within the endsystem for networked multimedia applications. There are four components in this framework namely|QoS speciication, QoS mapping, QoS enforcement, and protocol implementation. QoS speciications are at a high level, and use a small number of parameters to allow applications greater ease in specifying their requ...

With the growing adoption of the Service Oriented Architecture (SOA) in the industry and the wide deployment of Web services, users are increasingly requiring services that are capable of meeting their quality-of-service (QoS) requirements. In this paper, we propose a novel framework for QoS-aware Web service provisioning, which relies on QoS brokers, to mediate between clients and service prov...

Enhancements in technology always follow Consumer requirements. Consumer requires best of service with least possible mismatch and on time. Numerous applications available today are based on Web Services and Cloud Computing. Recently, there exist many Web Services with similar functional characteristics. Choosing “a-right” Service from group of similar Web Service is a complicated task for Serv...

A special Genetic Algorithm (GA) with simplex optimization method is proposed for the problem of selecting an optimal cloud service composition plan from a lot of composite plans on the basis of some global Quality-ofService (QoS) constraints. In this GA, some Simplex Method (SM) operations and a fitness function are provided. The design of the SM operations is made in the light of the characte...

Both congestion control and Quality of Service (QoS) are important quality attributes in computer networks. Specifically, for the future Internet architecture known as Named Data Networking (NDN), solutions using hop-by-hop interest shaping have shown to cope with the traffic congestion issue. Ad-hoc techniques for implementing QoS in NDN have been proposed. In this paper, we propose a new QoS ...

Based on the framework of employing traffic shaping at the UE and policing at the RNC, we propose a local and global QoS-aware token bucket parameter determination technique for traffic conditioning in 3G wireless networks in this paper. The local QoS-awareness is achieved by the tradeoff between the shaping delay and the out-ofprofile probability at the token bucket traffic shaper, and the glo...

Currently all web services are published and found by making use of the WSDL and UDDI techniques. This forces the consumers to find and bind services at design time since WSDL relies on static descriptions. Also the current techniques don’t address runtime service selection based on a dynamic assessment of QoS attributes. Hence in this paper, a Semantic QoS Web Services Agent Framework (SQoSWSA...

WebRTC introduces real-time media to any website with a few lines of code. This threatens the carriers’ stronghold – Voice, but could also be an opportunity to change their DNA and offer QoS web-calling alongside managed Voice. This paper proposes QoS enhanced web calling architecture for collaborative network providers, who negotiate session policy across different domains, (unlike the silo OT...

Many works have been carried out to find the efficient algorithms for QoS-aware service composition in recent years. Nevertheless, on one hand, some of these works only consider the local QoS attributes in Web services composition; on the other hand, some ideas derived from QoS selection algorithms for network routing are directly applied in service composition without any adaption. A service c...
