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 ... -
Mejoras en la identificación de tráfico de aplicación basado en firmas
Traffic identification has been based traditionally on transport protocol ports, associating always the same ports with the same applications. Nowadays that assumption is not true and new methods like signature identification ... -
Midiendo retardos y pérdidas en las redes móviles de alta velocidad
Mobile networks are constantly evolving, but still, due to their nature, it is not trivial to analayse how they face up different kinds of traffic. On the Internet a wide range of services can be found. Usually the majority ... -
Monitorización activa de altas prestaciones mediante la plataforma paneuropa ETOMIC
In this paper we present the first set of active measurements that we have made using the ETOMIC system. ETOMIC is a paneuropean traffic measurement infrastructure with GPS-synchronized monitoring nodes. Specific hardware ... -
Multiresolution analysis of optical burst switching traffic
In this paper, a Multiresolution Analysis is conducted in order to study the self-similar features of Optical Burst Switching (OBS) traffi c. The scenario consists of an OBS backbone with input traffic from a large number ... -
On fuzzy orderings of crisp and fuzzy intervals
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
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 ... -
On the nature of unused TCP connections in web traffic
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
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
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
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
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
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 ...
