Detección de congestión en la Internet europea
In this paper we present a study about the utilization of one-way delay measurements to detect and characterize network congestion in the european Internet. The experiments have been made using the ETOMIC platfom that ... -
Detecting disruption periods on TCP servers with passive packet traffic analysis
This paper presents a simple passive algorithm to monitor service availability. The algorithm is based on packet counting over a passive traffic trace of a population of clients accessing servers of interest. The major ... -
Effective burst preemption in OBS network
Burst preemption is the most effective technique to provide Quality of Service (QoS) differentiation in Optical Burst Switching (OBS) networks. Nonetheless, in conventional OBS architectures, when preemption happens the ... -
The ETOMIC active probing infrastructure: demo proposal
ETOMIC (www.etomic.org) is a European Union sponsored effort, that aims at providing a Paneuropean traffic measurement infrastructure. This infrastructure contains 15 PC based active probing nodes equipped with ... -
ETOMIC advanced network monitoring system for future Internet experimentation
ETOMIC is a network traffic measurement platform with high precision GPS-synchronized monitoring nodes. The infrastructure is publicly available to the network research community, supporting advanced experimental ... -
The European Traffic Observatory Measurement Infraestructure (ETOMIC)
The European Traffic Observatory is a European Union VI Framework Program sponsored effort, within the Integrated Project EVERGROW, that aims at providing an paneuropean traffic measurement infrastructure with high-precision, ... -
The European Traffic Observatory Measurement Infraestructure (ETOMIC): a testbed for universal active and passive measurements
The European Traffic Observatory is a European Union VI Framework Program sponsored effort, within the Integrated Project EVERGROW, that aims at providing a paneuropean traffic measurement infrastructure with highprecisi ... -
Evaluación de los sistemas inalámbricos 802.11b en entornos de alta movilidad para su implantación en una red de Infostations
Nowadays, users demand higher bandwidth Internet access with the ability to connect anywhere (or, at least, many-where) at anytime, with no restrictions imposed by mobility or the kind of information (voice or data) to ... -
Evaluation of preemption probabilities in OBS networks with burst segmentation
Preemption techniques have been recently proposed for service differentiation in Optical Burst Switching (OBS) networks. According to [1], an incoming burst with the same priority that the burst in service will preempt ... -
A first study on the use of interval-valued fuzzy sets with genetic tuning for classification with imbalanced data sets
Classification with imbalanced data-sets is one of the recent challenging problems in Data Mining. In this framework, the class dis- tribution is not uniform and the separability between the classes is often difficult. ... -
Garantía de calidad de servicio basada en la predicción del ancho de banda
This paper presents the architecture and performance evaluation of a neuronal estimator to predict network load in communication networks. System benchmarks are tested with real network traffic picked up from the 155 Mbps ... -
Herramienta de gestión en tiempo real de redes de área extensa
This paper presents PROMIS, a new network management tool based on a distributed architecture of traffic probes. It allows network managers to monitor traffic from any wide area network segment in real time using a WWW ... -
Improving efficiency of IP alias resolution based on offsets between IP addresses
In order to get a router-level topology in Internet, IP address alias resolution techniques allow to identify IP addresses that belong to the same router. There are several proposals to make this identification, some based ... -
Ingress traffic classification versus aggregation in video over OBS networks
Optical Burst Switched (OBS) networks may become a backbone technology for video-on-demand providers. This work addresses the problem of dimensioning the access link of an ingress node to the optical core network in a ... -
Internet mapping at IP level
The final objective of our research is to develop new techniques and ideas to create topology maps at IP level, representing Internet as a graph where nodes were routes. This means closer to reality. -
Internet technologies course with combined professor and on-line contents methodology
In this paper we present the experience and results in the teaching of a course titled “Internet Technologies”. This course, offered in Public University of Navarra (Spain), uses a special methodology that combines ... -
IP addresses distribution in Internet and its application on reduction methods for IP alias resolution
Discovery of Internet topology is an important and open task. It is difficulted by the high number of networks and internetworking equipments, and even by the dynamic of those interconnections. Mapping Internet at ... -
IP traffic prediction and equivalent bandwidth for DAMA TDMA protocols
The use of IP traffic prediction techniques for DAMA TDMA protocols is investigated in this paper. The predicted traffic distribution is derived when the input traffic shows long-range dependence features. Furthermore, an ... -
IPmiser: herramienta de medida and análisis de redes de alta velocidad
Las redes de área extensa IP generan en la actualidad un tráfico difícil de predecir y caracterizar. Así, se hace necesario disponer de herramientas que proporcionen monitorización en tiempo real de los enlaces, sin interrupción ...
