QoS online routing and MPLS multilevel protection: a survey

A survey of MPLS protection methods and their utilization in combination with online routing methods is presented in this article. Usually, fault management methods pre-establish backup paths to recover traffic after a failure. In addition, MPLS allows the creation of different backup types, and hence MPLS is a suitable method to support traffic-engineered networks. In this article, an introduction of several label switch path backup types and their pros and cons are pointed out. The creation of an LSP involves a routing phase, which should include QoS aspects. In a similar way, to achieve a reliable network the LSP backups must also be routed by a QoS routing method. When LSP creation requests arrive one by one (a dynamic network scenario), online routing methods are applied. The relationship between MPLS fault management and QoS online routing methods is unavoidable, in particular during the creation of LSP backups. Both aspects are discussed in this article. Several ideas on how these actual technologies could be applied together are presented and compared

Testing Delivery Systems in Transnational virtual learning: the vocational management training for the european tourism industry (VocMat) case study

This article discusses the lessons learned from developing and delivering the Vocational Management Training for the European Tourism Industry (VocMat) online training programme, which was aimed at providing flexible, online distance learning for the European tourism industry. The programme was designed to address managers ‘need for flexible, senior management level training which they could access at a time and place which fitted in with their working and non-work commitments. The authors present two main approaches to using the Virtual Learning Environment, the feedback from the participants, and the implications of online Technology in extending tourism training opportunities

De la Presencialitat i de l'online, on acaba una i comença l´altra? Propostes per a plantejar-les, disfrutar-les i valorar-les'

Hi ha dos tipus d'interrogants que ens plantegem en aquesta presentació: En primer lloc exposem un seguit de realitats que afecten directament al disseny de la nostra assignatura: els professors assumim habilitats apreses en tècniques de treball dels nostres estudiants: treball en equip, presentacions, debats.... Els uns i els altres entenem el mateix, del què i el com s'ha de treballar? Ho comprovarem. Alhora, ens preguntarem si els estudiants assumim habilitats tecnològiques del professorat? Moodle, wikis, Twitter, xats..... tots entenem el mateix i els fem servir de la mateixa manera? Fixem-nos en les dues perspectives, la del professor i la de l'estudiant, tant referent a dinamiques com a recursos, i ens adonarem que cal tenir en compte tant la una com l'altra. Aquestes reflexions afecten al plantejament de l'assignatura i ens deixen clar que hi ha molta feina a fer per trobar les respostes (conèixer als estudiants que tenim a les aules, explicar convenientment el que esperem dels estudiants, com plantegem l'assignatura i com l'avaluarem... ) No ens referim exclusivament a tenir un pla docent detallat a la maxima expresió, sinó que ens referim a reconèixer el com, el quan i el que expliquem als nostres estudiants, de manera que les regles del joc quedin enteses de la mateixa manera per una part i per l'altra. A partir d'aquí, i com a segon interrogant, ens plantejarem l'estructura que combina la part presencial i la part no presencial de l'assignatura: Quines són les activitats de les que puc treure més rendiment en la part presencial de l'assignatura i quines en la part no presencial? Quant temps i com calcular-lo, cal invertir en les activitats, tant per part dels estudiants com per part del professorat? Com podem avaluar una activitat que ha estat realitzada en part presencial i en part no presencial
