On fuzzy orderings of crisp and fuzzy intervals
Fuentes González, Ramón
; Burillo López, Pedro ; Mayor, Gaspar (EUSFLAT, 2001)
Contribución a congreso / Biltzarrerako ekarpena 
First, fuzzy membership functions for the assertion '[x,y] is a positive interval' are proposed and characterized via non-decreasing real maps. Last, using those functions together with the intervaldifference and the ... -
On linear prediction of Internet traffic for packet and burst switching networks
Morató Osés, Daniel ; Aracil Rico, Javier ; Díez, L. A. ; Izal Azcárate, Mikel ; Magaña Lizarrondo, Eduardo (IEEE, 2001)
Contribución a congreso / Biltzarrerako ekarpena
In this paper, we show that prediction algorithms in the least mean square error sense prove better in a burst rather than in a packet switching network. For the latter, further information about the packet arrival ... -

The popularity of the web and the requirements introduced by current web content have pushed for the development of new techniques that meet these challenges and improve the experience of the users. In particular, during ... -
On the use of balking for estimation of the blocking probability for OBS routers with FDL lines
Morató Osés, Daniel ; Aracil Rico, Javier (Springer Berlin Heidelberg, 2006)
Contribución a congreso / Biltzarrerako ekarpena
This paper deals with estimation of blocking probabilities for OBS switches with Fiber Delay Lines (FDLs) and full wavelength conversion. An incoming burst that finds the wavelengths occupied is temporarily stored in a ... -
Pamplona-traceroute: topology discovery and alias resolution to build router level Internet maps
García-Jiménez, Santiago ; Magaña Lizarrondo, Eduardo ; Morató Osés, Daniel ; Izal Azcárate, Mikel (IEEE, 2013)
Contribución a congreso / Biltzarrerako ekarpena
An Internet topology map at the router level not only needs to discover IP addresses in Internet paths (traceroute) but also needs to identify IP addresses belonging to the same router (IP aliases). Both processes, ... -
Planificación de la calidad de servicio para el acceso a Internet de las operadoras de cable
Magaña Lizarrondo, Eduardo ; Villadangos Alonso, Jesús ; Izkue Mendi, Edurne (2002)
Contribución a congreso / Biltzarrerako ekarpena
In this paper, the data traffic generated by users of cablemodems is studied. This service must be guaranteed for accomplishing certain Quality of Service and limiting the maximum bandwidth per user. The analysis presents ... -
A popularity-aware method for discovering server IP addresses related to websites
Torres García, Luis Miguel; Magaña Lizarrondo, Eduardo ; Izal Azcárate, Mikel ; Morató Osés, Daniel (IEEE, 2013)
Contribución a congreso / Biltzarrerako ekarpena
The complexity of web traffic has grown in the past years as websites evolve and new services are provided over the HTTP protocol. When accessing a website, multiple connections to different servers are opened and it is ... -
Predicción de tráfico de Internet and aplicaciones
Bernal, I.; Aracil Rico, Javier; Morató Osés, Daniel ; Izal Azcárate, Mikel ; Magaña Lizarrondo, Eduardo ; Díez, L. A. (2001)
Contribución a congreso / Biltzarrerako ekarpena
In this paper we focus on traffic prediction as a means to achieve dynamic bandwidth allocation in a generic Internet link. Our findings show that coarse prediction (bytes per interval) proves advantageous to perform dynamic ... -
Preemption window for burst differentiation in OBS
Klinkowski, Miroslaw; Careglio, Davide; Morató Osés, Daniel ; Solé Pareta, Josep (IEEE, 2008)
Contribución a congreso / Biltzarrerako ekarpena
This paper presents a novel control architecture for optical burst switching networks to efficiently apply burst preemption without the resources overbooking, which is specific to conventional OBS. Simulation results prove ... -
A proposal of burst cloning for video quality improvement in optical burst switching networks
Espina Antolín, Félix; Morató Osés, Daniel ; Izal Azcárate, Mikel ; Magaña Lizarrondo, Eduardo (2013)

Resolución de alias para el cálculo de topologías
García-Jiménez, Santiago ; Magaña Lizarrondo, Eduardo ; Izal Azcárate, Mikel ; Morató Osés, Daniel (2007)
Contribución a congreso / Biltzarrerako ekarpena
The network topology is a fundamental parameter for managers and researchers. The traditional methodology for discovering the topology of a network is based on the tool traceroute, used from several vantage points in ... -
A simple passive method to estimate RTT in high bandwidth-delay networks
Prieto Suárez, Iria; Izal Azcárate, Mikel ; Magaña Lizarrondo, Eduardo ; Morató Osés, Daniel (IARIA, 2015)
Contribución a congreso / Biltzarrerako ekarpena
This paper presents a simple passive algorithm to estimate the Round-Trip-Time (RTT) of a TCP connection in high bandwidth-delay network scenarios. In these scenarios, a passive RTT estimator that can be used on captured ... -

García-Jiménez, Santiago ; Magaña Lizarrondo, Eduardo ; Morató Osés, Daniel ; Izal Azcárate, Mikel (IEEE, 2009)
Contribución a congreso / Biltzarrerako ekarpena
One of the challenging problems related with network topology discovery in Internet is the process of IP address alias identification. Topology information is usually obtained from a set of traceroutes that provide IP ... -
