ABSTRACT
This paper proposes the deployment of a network software platform for experimentation called LabQoS that will allow the scientific community to establish scientific experiments relating to measure the performance of applications and services on the Internet and other network environments. Previous experiences have already deployed measurement systems, but they don’t incorporate the concept of control of the scenario to enable the performing of experiments. This LabQoS capacity makes it an innovative platform unique in its approach. A module called Test Environment Builder has been designed in order to monitor the operating parameters, and to propose adaptation strategies to handle the scenario control variables. We define an experimental data model that identifies the entities to be considered in the management of the platform. Assessment mechanisms are proposed to study the dynamic sensitivity of the control variables with respect to the parameters. LabQoS is based on QoSMETER architecture that addresses technological aspects such as user management, deployment tools, data collection, reporting, security, etc.

ABSTRACT
Deployment of quality-of-service (QoS) policies is becoming one of the biggest challenges for today's Internet Service Providers (ISPs). Nowadays, QoS does not only address specific technical standard metrics; it must be concern about other aspects such as user's final perception or regulations mandatory compliments instead. Although some efforts are being made on studying and analysing this new QoS scope, there are not still many advances on defining methodologies to deploy it on real network sceneries. UIT-T Rec. G-1000 makes an approachon this issue and provides a meaningful framework to users, service providers and regulators. Nevertheless, UIT-T G.1000 does not go an step further and remains at the 'theorical stage'. Our research group NQaS (Networking Quality and Security) is carrying out different initiatives focus on solving this new QoS dimension. This paper presents some of the on-going research areas of NQaS on the way to find an appropiate methodology to apply a global QoS policy in an ISP on the basis of the UIT-T G.1000 framework.

ABSTRACT
One of the most important tasks of a researcher consists in performing tests to validate the results of the research done. In a network related research work, with complex infrastructure and many configuration parameters, testing our work is usually rather mechanic, tedious and error prone if tests are done manually. In the Networking, Quality and Security Research Group, we have developed a generic test framework to automate this important task, composed of four kind of logical elements: a manager, agents, daemons and formatters. With these four elements, every phase of the process is automated, from test configuration to result formatting. The deployment of this framework has drastically reduced the time needed for the test phase and the number of errors due to mistakes. It has also allowed us to share resources among projects more easily and to schedule test sets when the devices are not being used.

ABSTRACT
This document describes several design proposals to enhance network sensor performance on multiprocessor architectures. Our main contributions are related to the design of an autonomous sensor and to the idea of performing some parallelization of the analysis. These proposals can be implemented in network sensors such as intrusion detection systems, network antivirus appliances, QoS monitors and any other device based on network traffic analysing. Taking a certain model of traffic analysis as our starting point, we look deeply into some design proposals to address the difficulties involved in the parallelization. In this work, we propose a series of resources that can help us to solve these difficulties. Later, we study the prototypes developed in order to test different design alternatives and, finally, present selected case studies. We finish by quantitatively analysing the results to validate our design proposals.

ABSTRACT
This paper offers an approach to the definition of access speed measurements. An ever growing increase of Internet Service Providers (ISP) and different types of technologies in the Internet access, makes it difficult for users to decide which is the best or most suitable connection to satisfy their needs. From these considerations, the possibility of the Internet users to obtain a real and neutral measurement of the service of their Internet access may help them to decide if it is covering their demands or, on the contrary, the provider is not complying with the terms of the contract. In order to perform this measurement, an Internet speed test through web interface has been defined, as well as the way to obtain a measure which can comply with the objective of giving users a proper idea of how their Internet access is working. This project is included in the Quality of Service (QoS) investigation area in our investigation group.

ABSTRACT
This paper presents velocimetro.org, the service developed by the Engineering Faculty of Bilbao to provide access speed measurements in Internet. The explosion of Internet Service Providers (ISP) and different types of technologies in Internet access, makes it difficult for Internet users to decide about the best or more acquaint access to cope with their needs. Velocimetro.org offers the possibility to obtain a neutral measurement of the quality of service (QoS) of the access to Internet. In this way, users can evaluate and decide if their ISP is covering their demands or, on the contrary, is not complying with the terms of the contract. From this point of view of an ISP, velocimetro.org allows to make comparisons of their service against their competitors.
