A study of packet losses in the EuQoS network
(2006)
Conference report
Open AccessAs Internet usage grows, more efforts are put into analyzing its internal performance, usually such analysis comes through simulation using different models. While simulation can provide a good approximation of network ... -
A survey and taxonomy of ID/Locator Split Architectures
(2014-02-26)
Article
Restricted access - publisher's policyThe IP-based addressing scheme currently supporting the whole routing architecture embeds some well-known limitations that may significantly hinder the deployment of new applications and services on the Internet. Indeed, ... -
A survey on the recent efforts of the Internet standardization body for securing inter-domain routing
(2015-04-07)
Article
Open AccessThe Border Gateway Protocol (BGP) is the de facto inter-domain routing protocol in the Internet, thus it plays a crucial role in current communications. Unfortunately, it was conceived without any internal security mechanism, ... -
An Approach to a Fault Tolerance LISP Architecture
(Springer Verlag, 2011)
Conference report
Open AccessNext Generation Internet points out the challenge of addressing "things" on both a network with (wired) and without (wireless) infrastructure. In this scenario, new efficient and scalable addressing and routing schemes ... -
An overview of quality of experience measurement challenges for video applications in IP Networks
(Springer, 2010-06-01)
Conference report
Open AccessThe increase in multimedia content on the Internet has created a renewed interest in quality assessment. There is however a main difference from the traditional quality assessment approaches, as now, the focus relies on ... -
Cross-layer multimedia quality enforcement through user aware information in wireless networks
(2010-06-14)
Conference report
Open AccessQuality assessment of multimedia traffic is a hot topic. In this paper we present a Multimedia Management System, which can be used on-line to assess and guarantee the quality of multimedia traffic in a wired and wireless ... -
Cross-talk effects on the Regenerator Allocation optimization
(2011)
Conference report
Open AccessThis paper studies the impact of considering crosstalk effects in the IA-RWA process and in the regenerator allocation algorithms. First of all, we evaluate if the regenerator allocation optimization is still useful when ... -
Diagnosis of route leaks among autonomous systems in the Internet
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference report
Restricted access - publisher's policyBorder Gateway Protocol (BGP) is the defacto inter-domain routing protocol in the Internet. It was designed without an inherent security mechanism and hence is prone to a number of vulnerabilities which can cause large ... -
Distributed Sampling for On-line SLA Assessment
(IEEE Communications Society, 2008-09-30)
Conference report
Open AccessNew business infrastructures over the Internet pose a new set of traffic constraints. In particular, multimedia and interactive contents require guarantees of bandwidth and delivery time. The broad deployment and real-time ... -
Effcient network performance assessment using Inter-Packet Arrival Times
(IEEE Computer Society Publications, 2010)
Conference report
Open AccessNetwork performance measurements have been broadly used in order to debug and to assess the reliability of the network. In general performance measurement is a resource consuming process, which in practice derives in ... -
HIRE: Hidden Inter-packet Red-shift Effect
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessOver the years, different techniques have been proposed to detect bottleneck bandwidth and available bandwidth of an end-to-end path. However, to the author's knowledge, no work has been conducted on detecting which link ... -
Improving learning automata-based routing in Wireless Sensor Networks
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference report
Open AccessRecent research in the field of Wireless Sensor Networks (WSNs) has demonstrated the advantages of using learning automata theory to steer the routing decisions made by the sensors in the network. These advantages include ... -
Improving TCP performance and reducing self-induced congestion with receive window modulation
(2019)
Conference report
Open AccessWe present a control module for software edge routers called Receive Window Modulation - RWM. Its main objective is to mitigate what we define as self-induced congestion: the result of traffic emission patterns at the ... -
Maximum Coverage at Minimum Cost for Multi-Domain IP/MPLS Networks
(IEEE Computer Society Publications, 2008)
Conference report
Open AccessAt present, service providers have several incentives to extend the reach of long-lived MPLS paths across domains. Providers, however, will face a number of trade-offs while choosing the optimal set of MPLS paths to be ... -
Methodology definition for reliable network experimentation
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Conference report
Open AccessAs researchers in the networking area keep adopting experimental network testing as a valid mechanism to develop, validate, and improve their research, it becomes more apparent that an overall framework supporting and ... -
Modeling physical-layer impairments in multi-domain optical networks
(IEEE Computer Society Publications, 2011)
Conference report
Restricted access - publisher's policyThe advantages of optical transparency are still confined to the boundaries of a domain, since the optical signals are subject to O/E/O conversions at the border nodes that separate two optical domains. The extension ... -
Movilidad Ip: macromovilidad, micromovilidad, calidad de servicio y seguridad
(Asociación de Técnicos de Informática, 2004-01)
Article
Open Accessa actual tendencia hacia la provisión de conectvidad ubícua, independientemente del lugar, instante, aplicación utilizada, o tecnología de acceso ha contrbuÍdo a acuñar la expresión, "Always Best Connected" (ABC), para ... -
Multi-domain optical routing: Is there life beyond extending BGP?
(2014-01-01)
Article
Open AccessThe design of new inter-domain optical routing protocols may start from scratch, or on the contrary exploits all the research already developed in IP networks with the Border Gateway Protocol (BGP). Even though the network ... -
