Static Pricing for a Network Service Provider

This article studies the static pricing problem of a network service provider who has a fixed capacity and faces different types of customers (classes). Each type of customers can have its own capacity constraint but it is assumed that all classes have the same resource requirement. The provider must decide a static price for each class. The customer types are characterized by their arrival process, with a price-dependant arrival rate, and the random time they remain in the system. Many real-life situations could fit in this framework, for example an Internet provider or a call center, but originally this problem was thought for a company that sells phone-cards and needs to set the price-per-minute for each destination. Our goal is to characterize the optimal static prices in order to maximize the provider's revenue. We note that the model here presented, with some slight modifications and additional assumptions can be used in those cases when the objective is to maximize social welfare.

Carrier Ethernet "label" scalability

A collection of slides from the authorpsilas seminar presentation is given

Improving Label Space Usage for Ethernet Label Switched Paths

Ethernet is becoming the dominant aggregation technology for carrier transport networks; however, as it is a LAN technology, native bridged ethernet does not fulfill all the carrier requirements. One of the schemes proposed by the research community to make ethernet fulfill carrier requirements is ethernet VLAN-label switching (ELS). ELS allows the creation of label switched data paths using a 12-bit label encoded in the VLAN TAG control information field. Previous label switching technologies such as MPLS use more bits for encoding the label. Hence, they do not suffer from label sparsity issues as ELS might. This paper studies the sparsity issues resulting from the reduced ELS VLAN-label space and proposes the use of the label merging technique to improve label space usage. Experimental results show that label merging considerably improves label space usage

Optimal Traffic Grooming in WDM using Lighttours

Recent developments in optical communications have allowed simpler optical devices to improve network resource utilization. As such, we propose adding a lambda-monitoring device to a wavelength-routing switch (WRS) allowing better performance when traffic is routed and groomed. This device may allow a WRS to aggregate traffic over optical routes without incurring in optical-electrical-optical conversion for the existing traffic. In other words, optical routes can be taken partially to route demands creating a sort of "lighttours". In this paper, we compare the number of OEO conversions needed to route a complete given traffic matrix using either lighttours or lightpaths

Operational Cost Reduction in WDM Networks using Lighttours

Wavelength division multiplexing (WDM) networks have been adopted as a near-future solution for the broadband Internet. In previous work we proposed a new architecture, named enhanced grooming (G+), that extends the capabilities of traditional optical routes (lightpaths). In this paper, we compare the operational expenditures incurred by routing a set of demands using lightpaths with that of lighttours. The comparison is done by solving an integer linear programming (ILP) problem based on a path formulation. Results show that, under the assumption of single-hop routing, almost 15% of the operational cost can be reduced with our architecture. In multi-hop routing the operation cost is reduced in 7.1% and at the same time the ratio of operational cost to number of optical-electro-optical conversions is reduced for our architecture. This means that ISPs could provide the same satisfaction in terms of delay to the end-user with a lower investment in the network architecture

All-Optical Unicast/Multicast Routing in WDM Networks

Optical transport networks (OTN) must be prepared in terms of better resource utilization, for accommodating unicast and multicast traffic together. Light-trees have been proposed for supporting multicast connections in OTN. Nevertheless when traffic grooming is applied in light-trees, resources can be underutilized as traffic can be routed to undesirable destinations in order to avoid optical-electrical-optical (OEO) conversions. In this paper, a novel architecture named S/G light- tree for supporting unicast/multicast connections is proposed. The architecture allows traffic dropping and aggregation in different wavelengths without performing OEO conversions. A heuristic that routes traffic demands using less wavelengths by taking advantage of the proposed architecture is designed as well. Simulation results show that the architecture can minimize the number of used wavelengths and OEO conversions when compared to light-trees

G+: Enhanced Traffic Grooming in WDM Mesh Networks using Lighttours

In this article, a new technique for grooming low-speed traffic demands into high-speed optical routes is proposed. This enhancement allows a transparent wavelength-routing switch (WRS) to aggregate traffic en route over existing optical routes without incurring expensive optical-electrical-optical (OEO) conversions. This implies that: a) an optical route may be considered as having more than one ingress node (all inline) and, b) traffic demands can partially use optical routes to reach their destination. The proposed optical routes are named "lighttours" since the traffic originating from different sources can be forwarded together in a single optical route, i.e., as taking a "tour" over different sources towards the same destination. The possibility of creating lighttours is the consequence of a novel WRS architecture proposed in this article, named "enhanced grooming" (G+). The ability to groom more traffic in the middle of a lighttour is achieved with the support of a simple optical device named lambda-monitor (previously introduced in the RingO project). In this article, we present the new WRS architecture and its advantages. To compare the advantages of lighttours with respect to classical lightpaths, an integer linear programming (ILP) model is proposed for the well-known multilayer problem: traffic grooming, routing and wavelength assignment The ILP model may be used for several objectives. However, this article focuses on two objectives: maximizing the network throughput, and minimizing the number of optical-electro-optical conversions used. Experiments show that G+ can route all the traffic using only half of the total OEO conversions needed by classical grooming. An heuristic is also proposed, aiming at achieving near optimal results in polynomial time

Caracterización de las competencias transculturales del terapeuta ocupacional en su trabajo con grupos étnicos en un contexto urbano

Este trabajo de grado está enmarcado en una investigación de tipo social de acción – participación, con carácter democrático y de perspectiva comunitaria porque busca describir y analizar ideas, creencias, significados, conocimientos y prácticas de grupos, culturas y comunidades (Patton, 2002) partiendo de un enfoque descriptivo, reflexivo y comprensivo. El objetivo de éste estudio fue identificar las competencias transculturales del Terapeuta Ocupacional para trabajar en y con personas del ciclo vital de juventud pertenecientes a grupos étnicos a partir del estudio de su desempeño ocupacional desde la mirada individual y colectiva de su cotidianidad. El estudio comprendió grupos indígenas, gitanos y afrodescendientes que habitan en un contexto urbano. Partió de la pregunta ¿si la etnia y la cultura determinan características particulares en el desempeño ocupacional de las personas, entonces es una condición que demanda en el Terapeuta Ocupacional competencias transculturales particulares para desarrollar acciones en y con diferentes grupos étnicos?; se fundamenta en conceptos como: cultura, Etnia, raza, competencias transculturales, compatibilidad cultural, desempeño ocupacional, características del y la joven y terapia ocupacional. Como resultado se estableció que el contexto, la cultura y las características propias de la edad son factores directos en la consolidación de la identidad que le permiten al y la joven de cualquier grupo étnico establecer un autoconocimiento y un comportamiento claro frente a la rutina, los intereses, las motivaciones y las relaciones interpersonales. En este sentido el terapeuta ocupacional tiene que desarrollar ciertas capacidades para trabajar con grupos étnicos, generando estrategias a partir de los conceptos y enfoques propios de su que hacer y adaptarlos a las características del ser humano; de esta manera es importante contar con competencias transculturales basadas en el saber ser, saber convivir, saber conocer y saber hacer. Es decir, la transculturización del desempeño del Terapeuta Ocupacional, es una cualidad que implica flexibilizar el que hacer y adaptar las acciones al amplio rango y variación de las normas culturales de las personas.
