The emerging marketplace for online free services in which service providers earn revenue from using consumer data in direct and indirect ways has lead to significant privacy concerns. This begs understanding of the following question: can the marketplace sustain multiple service providers (SPs) that offer privacy-differentiated free services? This paper studies this problem of market segmentat...

Multi-Protocol Label Switching is a relatively new technology based on the association of labels with routes and the use of labels to forward packets. In other words MPLS integrates the label-swapping paradigm with network-layer routing. Differentiated Services define a model for implementing scalable differentiation of QoS in the Internet. Packets are classified and marked, policed and shaped ...

Differentiated Services is the most advanced method for traffic management which provides QoS. QoS is essential for today’s internet. QoS represents set of techniques necessary to manage throughput, packet loss and delay. Traffic Conditioners or Policers are the most important components of differentiated services. In this research, different Traffic Conditioners or Policers are compared on the...

Internet Telephony has been deemed as a promising candidate for the next generation telephone system. However, unstable voice quality is the main problem that prevents the Internet Telephone from competing with the traditional circuit switched telephone. Current Internet supports only a best-effort service class, which does not provide any bandwidth or delay guarantee for the voice packets. Dur...

To achieve some level of QoS (quality of service) assurance, DiffServ (Differentiated Services) domains have SLAs (service level agreements) with their users and neighboring domains, which describe the QoS level the service provider is committed to provide and the amount of traffic users or neighboring domains are allowed to send. All incoming flows must conform to certain pre-determined SLA wi...

Abstrncr . Admission eontml is a critical element for supporting Quality-of-Service in networks. We pmpase and evaluate the performance of an adaptive inadmission contml scheme that is suitable for use in a Differentiated Services Internet backbone. The pmposed scheme impmves upon the admission cuotml scheme by measur. ing the maximal arrival rate envelope at an ingress node and adding an adapt...

The Differentiated Services approach is currently intensively discussed in the Internet community. It will also bring benefits for multicast applications that need quality of service support. For instance, a highly reliable multicast can be provided based on Expedited Forwarding. However, current efforts mainly concentrate on unicast services, whereas multicast services have not been addressed ...

The goal of this paper is to study pricing of differentiated services and its impact on the choice of service priority at equilibrium. We consider both TCP connections as well as non controlled (real time) connections. The performance measures (such as throughput and loss rates) are determined according to the operational parameters of a RED (Random Early Discard) buffer management. The latter ...

This memo describes several Rate Adaptive Shapers (RAS) that can be used in combination with the single rate Three Color Markers (srTCM) and the two rate Three Color Marker (trTCM) described in RFC2697 and RFC2698, respectively. These RAS improve the performance of TCP when a TCM is used at the ingress of a diffserv network by reducing the burstiness of the traffic. With TCP traffic, this reduc...

We present an adaptive controlled scheduler for heterogeneous applications running on general purpose computers. Our scheduler can effectively support diverse application requirements. It employs uniform rate-based sharing. Application heterogeneity is satisfied by partitioning CPU capacity into service classes, each with a different criterion for admission control. As a result, we are able to ...
