An Integrated Multi-service Software Simulation Platform: SIMPSONS Architecture

2005

This paper describes SIMPSONS (SIp and MPls Simulations On NS-2), which is a software platform for simulating multiple network scenarios, such as Telephony Over IP (TOIP), and multi-services networks extending the functionalities of Network Simulator NS-2. The innovative aspects of SIMPSONS is the complete integration of control protocols and traffic engineering mechanisms inside the same simulation tool. In fact, next generation networks must meet basically two fundamental requirements: support of Quality of Service (QoS) and Traffic Engineering (TE) functionalities. SIMPSONS is able to simulate DiffServ, MPLS, OSPF and SIP and their interaction in everything TOIP scenario. So with this po…

Is Admission-Controlled Traffic Self-Similar?

2002

It is widely recognized that the maximum number of heavy-tailed flows that can be admitted to a network link, while meeting QoS targets, can be much lower than in the case of markovian flows. In fact, the superposition of heavy-tailed flows shows long range dependence (self-similarity), which has a detrimental impact on network performance. In this paper, we show that long range dependence is significantly reduced when traffic is controlled by a Measurement-Based Admission Control (MBAC) algorithm. Our results appear to suggest that MBAC is a value added tool to improve performance in the presence of self-similar traffic, rather than a mere approximation for traditional (parameter-based) ad…

Neuro-ICU patient disposition

2018

This article revises the recent evidence on ICU admission criteria for acute neurological patients [traumatic brain injury (TBI) patients, postoperative neurosurgical procedures and stroke].The appropriate utilization of ICU beds is essential, but it is complex and a challenge to attain. To date there are no widely accepted international guidelines for managing these acute brain-injured patients (stroke, TBI, postneurosurgery) in the ICU. The criteria for ICU admission after neurological acute injury, high-dependency unit or a specialized neurosurgical ward vary from institution to institution depending on local structures and characteristics of the available resources. Better evidence to s…

Predictors of mortality in COPD patients after hospitalization due to an exacerbation

2019

Aim: Identify factors related to mortality at 6 months after hospitalization by an acute COPD exacerbation (AECOPD). Method: We performed a 12-month prospective, observational study (July 2017-June 2018) that included COPD patients admitted by an AECOPD. Sociodemographic data, comorbidities, functional and clinical parameters were collected. Mortality at 6 months of admission was considered the end point. Results: 278 consecutive patients were enrolled, of whom 48 (16.2%) died during 6 months after AECOPD. Univariate analysis showed that age (p Conclusions: In COPD patients, Barthel Index, grade of dyspnea and previous hospitalizations are independent risk factors for mortality at 6 months,…

Web Server Support for e-Customer Loyalty through QoS Differentiation

2013

The paper deals with the problem of offering predictive service in e-commerce Web server systems under overload. Due to unpredictability of Web accesses, such systems often fail to effectively handle peak traffic, which results in long delays and incomplete transactions. As a consequence, online retailers miss an opportunity to attract new customers, retain the loyalty of regular customers, and increase profits. We propose a method for priority-based admission control and scheduling of requests at the Web server system in order to differentiate Quality of Service (QoS) with regard to user-perceived delays, i.e., Web page response times provided by the system (as opposed to HTTP request resp…

Supporting scalable video transmission in MANETs through distributed admission control mechanisms

2009

Emerging multimedia applications over mobile devices are becoming very popular, especially over infrastructure wireless networks such as cellular and WLANs. However, providing this kind of services over infrastructureless networks like ad hoc networks presents many additional problems. One of these problems is how to share resources fairly among the users involved. In this article we propose a QoS framework supporting scalable video streaming in mobile ad hoc networks based on distributed admission control and video traffic awareness. Our framework promotes fairness between video flows in terms of resource consumption. It also guarantees a significant reduction of the idle times experienced…
