Multicast routing and wavelength assignment in optical networks with particle swarm optimization

Large bandwidth on hand in WDM networks is the best choice for increasing tra c demand; although, routing and wavelength assignment (RWA) problems still remain a challenge. This work proposes a novel method to solve multicast-RWA problems, using multi-objective Particle Swarm Optimization (PSO), implementing four competitive ap- proaches of state-of-the-art. Such algorithms minimize simultaneously the hop count, the number of splitting power light, the number of split- ter node and the balancing of multicast tree for a given set of multicast demands. This way, a set of optimal solutions (known as Pareto set) is obtained in one run of the algorithms, without a priori restrictions. Sim- ulation results prove the viability of the PSO proposal and the advantage compared on classical approaches as Multicast Open Shortest Path First routing algorithm and Least Used wavelength assignment algorithm.IV Workshop Arquitectura, Redes y Sistemas Operativos (WARSO)Red de Universidades con Carreras en Informática (RedUNCI

El acompañamiento pedagógico interno y la práctica docente en una institución educativa pública de Ayacucho

La presente investigación tuvo el propósito de analizar cómo se vincula el acompañamiento pedagógico interno y la práctica docente en una institución educativa pública de Ayacucho. Para ello, se consideró una metodología con base en el paradigma interpretativo, con un enfoque cualitativo y con el tipo de diseño de estudio de caso. Para obtener la información se utilizó la técnica de la entrevista, siendo el instrumento, una guía de entrevista con preguntas semi estructuradas. El muestreo empleado en la presente investigación fue de tipo no probabilístico, es decir, se llevó a cabo por selección intencional del propio investigador. Así, la muestra quedó conformada por 3 docentes, quienes trabajan por horas, tienen más de tres años de servicio y tienen la condición de acompañados en una institución educativa pública focalizada con el programa de jornada escolar completa. Se realizó el análisis de la información recogida con el cuestionario. Finalmente, se concluyó que el acompañamiento pedagógico interno, en una institución educativa, se considera una oportunidad que ofrece estrategias para el fortalecimiento de la práctica docente, promovido con un enfoque crítico reflexivo y cumpliendo con los protocolos del proceso de acompañamiento pedagógico.This research has the purpose of analyzing how internal pedagogical accompaniment and teaching practice are linked in a public educational institution in Ayacucho. For which, a methodology with an interpretive paradigm was considered, a qualitative approach, of a design type is the case study. To obtain the information, the interview technique was used, through the use of the questionnaire instrument with semi-structured questions. The sample used in this research is of a non-probabilistic type, it was carried out by intentional selection by the researcher himself of the 3 hourly teachers who have more than three years of service in condition accompanied in a public educational institution focused on the program of Full school day. For the investigation, qualitative information was considered and it is concluded that the internal pedagogical accompaniment in an educational institution is considered as an opportunity that offers a set of strategies for strengthening the teaching practice, promoted with a reflective critical approach and complying according to the protocols of the pedagogical accompaniment process
