Propuesta de Lineamientos Técnicos para Proporcionar Alta Disponibilidad de Servicio en el contexto de una NGSDP

Actualmente, las NGSDP constituyen la tercera generación de SDP, incorporando principios SOA (Service Oriented Architecture) relacionados con la orquestación y gestión de servicios, lo cual le permite a los operadores y terceros, desarrollar servicios y desplegarlos sobre diferentes arquitecturas. Sin embargo, uno de los grandes retos en este contexto, es mantener el porcentaje de disponibilidad de los servicios tradicionales de telecomunicaciones en los nuevos servicios convergentes. El presente artículo presenta una propuesta para mantener niveles de alta disponibilidad de servicio en el contexto de una NGSDP, a través del planteamiento de una serie de criterios y lineamientos técnicos relacionados con este contexto.

Service discovery platform for ubiquitous environments

Revista Facultad de Ingeniería

Current approaches for ubiquitous services retrieval are mostly limited to the matching of their inputs/ outputs possibly enhanced with some ontological knowledge. Recent research has demonstrated that this approach is not sufficient to discover relevant services. Motivated by these concerns, this work proposes a service discovery platform in ubiquitous environments based on behavior matchmaking. We argue that in many situations the service composition process requires a service discovery phase based on matchmaking of behavior specifications of the components. Consequently, even if a service that meets exactly the user requirements does not exist, the most similar ones will be retrieved.

Plataforma para servicios de facturación y pago en ambientes ubicuos

In the short term, we can see a new stage named as ubiquitous computing, which allows services and applications located within fixed or mobile devices to auto-run according to the context of the user, and that those devices have the ability and intelligence to manage the processing and exchange of information according to the needs of the user. This makes the ubiquitous technologies and services that obviously are implemented on them, include new challenges relating to the security (privacy, authentication, authorization, non-repudiation), that needs to be increased on the payment mechanisms that will decide if the services ubiquitous can be commercially safe and viable. The ubiquitous services are emerging with great force. Therefore, it is considered of great importance to begin the study, design, development, implementation and deploy of these services in our countr...

ProViNet: Uma Plataforma para Gerenciamento de Redes Virtuais Programáveis

However, to ensure a harmonious relationship between users, network applications and virtual networks, considerable management efforts are needed. In this paper we propose the ProViNet platform, a solution for managing the deployment of network applications in Programmable Virtual Networks (PVN). In addition to the management facilities, ProViNet contributes with an architecture that allows sharing the control plane of PVN in a scalable way. During the development of this work we identified the need for a standard representation of programmable virtual infrastructures, so it is also proposed an extension of the programmable virtual networks description language VXDL. In order to verify the feasibility of the proposed platform, we implemented a prototype, which is analyzed and evaluated in this paper.

An Approach to Overcome the Complexity of Network Management Situations by Mashments

by Oscar Caicedo and Felipe Estrada-Solano

2014 IEEE 28th International Conference on Advanced Information Networking and Applications, 2014

In this paper, we introduce an approach that allows network administrators to overcome the complexity of handling these network management situations (called NMSits). The approach is made up of Mashments that are special mashups used to cope with NMSits, the process to develop and execute Mashments, and the Mashment Maker that supports such model and process. We use IT Service Management metrics to evaluate our approach, measuring the complexity of facing, with and without the Maker, a specific NMSit that occurs in several networks based on the Software Defined Networking paradigm. The evaluation results demonstrate that the complexity decreases when network administrators use our approach to handle NMSits.

A mashup ecosystem for network management situations

In this paper, we introduce a novel mashup ecosystem, called Mashment Ecosystem, that allows Network Administrators to conduct on a Mashment Maker the activities and interactions necessary to provide Mashments. Mashments are mashups aimed to tackle network management situations. We evaluate the Mashment Ecoystem by estimating with the Keystroke-Level Model and measuring in a test scenario the time that Network Administrators take to perform the activities of creating, launching, and publishing Mashments. Similarly, we evaluate the time for retrieving information about a network management situation by using or not Mashments. The evaluation results corroborated that Network Administrators, in our ecosystem, need short-time to deal with network management situations.

Then, it is necessary to complement the JSLEE functionalities with
