Multiprotocol label switching (MPLS) is a versatile solution to address the problems faced by present-day networks—speed, scalability, quality-of-service (QoS) management, and traffic engineering. MPLS has emerged as an elegant solution to meet the bandwidth-management and service requirements for nextgeneration Internet protocol (IP)–based backbone networks. MPLS addresses issues related to sc...

Software-defined networking (SDN) provides a means of configuring the packet-forwarding behavior of a network from a logically-centralized controller. Expressive, high-level languages have emerged for expressing data-plane configurations, and new tools allow for verifying packet reachability properties in real time. But SDN largely ignores quality of service (QoS) primitives, such as queues, qu...

FU, ZHI. Network Management and Intrusion Detection For Quality Of Network Services (Under the direction of Dr. S. Felix Wu) The explosive growth in worldwide communication via the Internet has increased the reliance of organizations and individuals on the electronically transmitted information, which consequently created rising demands to protect data from information leakage, corruption or al...

The application environments and connection with the Internet require that wireless ad hoc networks should support Quality-of-Service (QoS). In a wireless ad hoc network, supporting quality-of-service is very difficult because of the inherent characteristics of wireless channel and the frequent change of network topology. This paper comprehensively summarizes and deeply analyzes the researches ...

0163-6804/98/$10.00 © 1998 IEEE elecommunication Information Network Architecture (TINA) has been under development at the TINA Consortium (TINA-C) core team since 1993, and the project released final specifications at the end of 1997.1 TINA addresses three major domains of network architecture: • The distributed processing environment (DPE) • Network resource architecture • Service architectur...

This paper presents a dynamic hybrid Service Overlay Network (SON) for service composition for multimedia delivery in mobile networks. The overlay considers the nomadic nature of mobile nodes in the decision for node placement within the overlay as well as the types of services provided and expected Quality of Service (QoS) levels. Dynamic re-organization of the overlay reflects changes in stab...

Emerging mobile applications rely their delivery on the serviceability of the underlying wireless networks. However, this serviceability, expressed in terms of quality of service (QoS) provided by a network available to a service user at a given geographical location and time, is a priori unknown. In turn, it influences the application-level QoS provided to a mobile service user. As a solution ...

At present, quality of service (QoS) has become an important guidance in selecting a satisfactory web service when many similar web services provide overlapping or identical functionalities. Therefore people have carried out many studies on definition and standardization of QoS properties and QoS-based selecting algorithms of web service. Current web service selection usually adopt linear weigh...

End-to-end QoS (Quality of Service) provisioning over heterogeneous networks is a major challenge. The poor communication between Service Providers, the increasing complexity of the supported services, the need for fulfillment of end-toend requirements represent the main problems to be solved by the new QoS frameworks. This paper presents a novel system architecture for an end-to-end QoS framew...

The growing number of web services advocates distributed discovery infrastructures which are semantics-enabled and support quality of service (QoS). In this paper, we introduce a novel approach for semantic discovery of web services in P2P-based registries taking into account QoS characteristics. We distribute (semantic) service advertisements among available registries such that it is possible...
