A new proposal for assuring services in internet

In this paper we present a new mechanism to provide an assured service in terms of target rate and fair excess bandwidth, like the Internet Assured Service. Research in Internet Assured Service faced up both questions in separate ways proposing different traffic conditioners to work with the RIO buffer management, and proposing different modifications to this buffer management, among others. In this work, we suggest using a buffer management scheme different from RIO that also treats in-of-profile and out-of-profile packets differently but avoiding interference between them. This scheme is used together with the Counters Based traffic conditioner because of its high accuracy in guaranteeing target rates. We evaluate and compare by simulation the performance of our proposal using TCP RENO sources. One important issue to be considered is that the proposal is a feasible alternative to the standard architecture for Differentiated Services in Internet.This work was supported by the Spanish Research Council under grant TIC2000-1734- C03-03

IP Law Book Review: \u3cem\u3eConfiguring the Networked Self: Law, Code, and the Play of Every Day Practice\u3c/em\u3e

Julie Cohen\u27s Configuring the Networked Self is an extraordinarily insightful book. Cohen not only applies extant theory to law; she also distills it into her own distinctive social theory of the information age. Thus, even relatively short sections of chapters of her book often merit article-length close readings. I here offer a brief for the practical importance of Cohen’s theory, and ways it should influence intellectual property policy and scholarship

A review of historical developments of quality assessment in industry and healthcare

Purpose: This study reviewed the literature on the historical development of quality assessment methods in industry and in healthcare. A comparative analysis of quality methods in industry and healthcare was conducted to examine the gap between methods in the two sectors. An attempt was then made to examine the latest approaches to quality assessment in healthcare and finally a proposal has been offered for a more effective approach to tackling the problem of quality in healthcare. Design/methodology/approach: Firstly, a review of the evolution of quality assessment in industry and healthcare was conducted. This was based on books written by prominent experts in the field of quality. secondly, a study of the current approaches in healthcare was undertaken. Publications from varied sources were selected and reviewed. The literature consulted includes worldwide operations research and healthcare sources including dissertations, the internet and reference lists of relevant articles. The journal papers and conference proceedings were selected according to the following criteria: Objective: the study must be aimed at measuring or improving quality both. It could also be aimed at developing new ways of measuring the quality of health care; Method: observational studies, experimental trials or systematic reviews; Setting: study should be in a hospital setting and not narrowed to quality of clinical cares. Findings: This study showed that the concept of quality management and its control in healthcare is not as advanced as it is in industry. Moreover, it seemed that most researchers, who set out to assess quality of care in one way or the other, have had differing views of quality and the factors that contribute to its assessment. It was also deduced that the way forward in healthcare quality is the development of systems that give staff ownership and pride in a way that is akin to the era of the craftsmen

Aereo and Internet Television: A Call to Save the Dukes (A La Carte)

If it looks like a duck, swims like a duck, and quacks like a duck, it is probably a duck. The most recent U.S. Supreme Court decision regarding the Copyright Act employed this “duck test” when determining that Aereo, an Internet content-streaming company, violated the Copyright Act by infringing on the copyrights of television broadcast networks. The Supreme Court ruled that Aereo\u27s Internet streaming services resembled cable television transmissions too closely. Therefore, by streaming copyrighted programming to its subscribers without the cable compulsory license, Aereo violated the Transmit Clause of the 1976 Copyright Act. Subsequently, Aereo used this Supreme Court decision to obtain a compulsory license from the Copyright Office but was denied. Forced back into litigation, Aereo filed for Chapter 11 Bankruptcy This Issue Brief describes Aereo’s technology, the litigation that followed, and the related precedent, and concludes that the district court should have granted Aereo a Section 111 Statutory License in line with the Supreme Court’s “duck test.” It considers the implications of the Court’s preliminary injunction against Aereo’s “a la carte” TV technology, what this means for the future of similar technological innovation, and the effects on consumers and competition

End-to-end elasticity control of cloud-network slices

The design of efficient elasticity control mechanisms for dynamic resource allocation is crucial to increase the efficiency of future cloud-network slice-defined systems. Current elasticity control mechanisms proposed for cloud- or network-slicing, only consider cloud- or network-type resources respectively. In this paper, we introduce the elaSticity in cLOud-neTwork Slices (SLOTS) which aims to extend the horizontal elasticity control to multi-providers scenarios in an end-to-end fashion, as well as to provide a novel vertical elasticity mechanism to deal with critical insufficiency of resources by harvesting underused resources on other slices. Finally, we present a preliminary assessment of the SLOTS prototype in a real testbed, revealing outcomes that suggest the viability of the proposal.Peer ReviewedPostprint (published version
