“…The most remarkable approach for automated service adaptation is presented within the scope of the TeamCom project [50] [49] [52] (see Figure 13), which deals with cases in which the developer describes the business process using BPEL but the resulting BPEL process is not necessarily executable on a BPEL-engine. The TeamCom platform translates the resulting BPEL process in XML; next, these files are in turn transformed into Java code that is deployable on a JAIN Service Logic Execution Environment (JSLEE) server [53].…”

“…Notwithstanding such predominance for representing business process, BPEL/BPEL4REST have not been developed for control of specific communication services [50], particularly in real time like usually Telecom services require. Consequently, BPEL and its associated execution servers are not appropriate in the sense that they cannot provide the availability requirements necessary for convergent service execution [48].…”

“…The IMS services may be installed in application servers or in media servers. In the Service layer, most of the researchers [50] [128] have focused on the use of JSLEE as the subjacent application server for executing convergent services.…”

A convergent service is defined as a service that exploits the convergence of communication networks and at the same time takes advantage of features of the Web. Nowadays, building up a convergent service is not trivial, because although there are significant approaches that aim to automate the service composition at different levels in the Web and Telecom domains, selecting the most appropriate approach for specific case studies is complex due to the big amount of involved information and the lack of technical considerations. Thus, in this paper, we identify the relevant phases for convergent service composition and explore the existing approaches and their associated technologies for automating each phase. For each technology, the maturity and results are analysed, as well as the elements that must be considered prior to their application in real scenarios. Furthermore, we provide research directions related to the convergent service composition phases.

“…Para la fase de composición, enfoques como [5][6][7][8][9] construyen herramientas o ambientes de creación de servicios; otros como [10][11][12] se enfocan en la técnicas de recuperación y composición dinámica, haciendo énfasis en alternativas semánticas. En la fase de despliegue, trabajos como [13][14][15] realizan un despliegue inicial del servicio, considerando en él solo las funciones o lógica principal, y dejando de lado actividades de configuración, activación e instalación, todas ellas necesarias para activar adecuadamente la fase de operación del servicio. Por último, la fase de operación tiene una relevancia empresarial alta, principalmente por ser esta la que prepara el servicio para su consumo final.…”

ResumenEl aprovisionamiento de servicios de telecomunicaciones ha cambiado notablemente en los últimos 30 años; se ha pasado de modelos estáticos, rígidos y controlados por un solo actor de negocio a modelos dinámicos, flexibles, con múltiples actores en la cadena de valor y orientados a los usuarios finales. Diferentes enfoques han planteado modelos de aprovisionamiento que cumplan requerimientos específicos a los operadores de telecomunicaciones. Sin embargo, aún no están claros los procesos principales que deben desarrollarse en cada fase del ciclo de vida del servicio para que permitan una integración efectiva entre diferentes modelos de aprovisionamiento. En este artículo se presenta una aproximación al modelo inicial de aprovisionamiento de servicios convergentes, el cual abstrae los principales procesos dentro de las fases de diseño, despliegue y operación del servicio. De igual manera, se presenta un piloto funcional que ejecuta de manera automática el proceso de despliegue inicial en un entorno convergente con base en los procesos definidos en esta fase. Finalmente, el mecanismo es sometido a una prueba de escalabilidad para evaluar su desempeño.Palabras clave: servicios convergentes, JSlee, aprovisionamiento de servicios, mecanismo de despliegue automático.

“…In (Lehmann, et al, 2009) the authors also propose convergent services orchestration using BPEL, but unlike previous work, the adaptation module is used at design time, so that it does not affect performance; however, the orchestration must be performed by means of manual techniques, which requires advanced knowledge on different protocols and asynchronous events of the telecommunications domain, for which the BPEL language is not very suitable (Bond, Cheung, & Levenshteyn, 2009). Based on the previous state of the art, it is possible to state that the way to orchestrate services in converged environments is not yet clear.…”

A widely adopted solution in order to obtain a low Time to Market by a segment of Telecommunication operators is the use of the concept of service composition because their philosophy is to reuse software components previously implemented. The composition has two phases, the synthesis and orchestration, understanding the second one as a challenge to converged services because it requires extensive technical knowledge and experience. This article proposes a mechanism based on graphs and Petri Nets to automate the orchestration of services in converged JS-LEE environments, which operates at design time in order to not affect performance in the execution of composite services. The results demonstrate that the mechanism can transform an abstract process with 20 component services in an executable JSLEE service, without exceeding 500 ms. Keywords: Automatic Orchestration, JAIN SLEE, Service Composition. ResumenUna solución ampliamente adoptada para obtener un bajo Time to Market por parte de los operadores de Telecomunicaciones, es la utilización del concepto de composición de servicios ya que su filosofía es reutilizar componentes software previamente implementados. La composición tiene dos fases, la síntesis y la orquestación, siendo la segunda un reto en los servicios convergentes debido a que requiere amplio conocimiento técnico y experiencia. En este artículo se propone un mecanismo basado en Grafos y redes de Petri para automatizar la orquestación de servicios sobre entornos convergentes JSLEE, el cual funciona en tiempo de diseño con el propósito de no afectar el rendimiento en la ejecución del servicio compuesto. Los resultados demuestran que el mecanismo puede transformar un proceso abstracto con 20 servicios componentes, en un servicio ejecutable JSLEE, sin superar los 500 ms. Palabras clave: Composición de servicios, JAIN SLEE, Orquestación Automática.
