This paper presents a new scalable buffer-management scheme for IP Differentiated Services. The scheme consists of a Differentiated Random Drop (DRD) algorithm using feedback from a virtual scheduler. DRD choses a queue to perform an early packet drop to avoid congestion according to a specific probability function. First it will be shown that DRD in conjunction with first-come firstserved sche...

The goal of this paper is to make an architecture framework for wireless sensor networks that is used for water management application. The proposed framework focuses on offering differentiated services for sensor nodes. Differentiated services are supported based on the information passed from the sensor node to differentiated service motes. Three differentiated services are offered gold, silv...

Next generation Internet architectures will consider the Differentiated Services paradigm for the provision of quality of service to individual customers needs and applications. This paper addresses the definition and deployment of specific network services in a DiffServ environment. The proposed network services and the underlying traffic engineering methods are analyzed and simulated. Simulat...

The increasing demand of Quality of Service (QoS) has lead in the last years to the definition of architectures that modify the best-effort Internet, though in a backward compatible way. The Integrated Services (IS) architecture, tightly coupled with the RSVP protocol, is first one that has been developed by IETF. Soon after its deployment some experimentation of IS networks raised a serious pr...

With the number of e-Business applications dramatically increasing, a service level agreement (SLA) will play an important part in Web services. The SLA is a combination of several quality of services (QoS), such as security, performance, and availability, agreed between a customer and a service provider. Most existing research addresses only one of these QoS metrics. Furthermore, in the case o...

All the new emerging QoS service architectures are motivated by the desire to improve the overall performance of IP networks. Integrated Services (Intserv), Differentiated Services (Diffserv), MultiProtocol Label Switching (MPLS) and constraint-based routing are all technologies starting to coexist together in today’s Internet to provide means for the delivery of end-to-end QoS to applications ...
