Thesis ZEROMQ COMO UNA ALTERNATIVA DEL SERVICIO DE NOTIFICACIÓN DE CORBA PARA ALMA COMMON SOFTWARE (ACS)(Universidad Técnica Federico Santa María, 2016) Rojas Zagals, Diego Alejandro; Universidad Tecnica Federico Santa Maria UTFSM DEPARTAMENTO DE ELECTRONICA; ESCARATE MONETTA, PEDRO; CREIXELL FUENTES, WERNER UWEAtacama Large Millimeter/submillimeter Array (ALMA) observatory works on a distributed manner and it has an especially design framework to control it, called ALMA Common software (ACS). This framework it is based on the Common Object Request Broker Architecture (CORBA) making an abstraction of it and providing multiple grouped services as modules inside ACS, thus facilitating distributed applications construction. One of the ALMA Common Software oered services is messaging exchanges between ACS objects. This service called ACS Noti cation Channel is based on CORBA service, Noti cation Service and operates an asynchronic message transmission. Currently there are many service alternatives with better performance and usability like ZeroMQ framework. This thesis investigates and implements a noti cation service alternative from ALMA using a new technology. This process consists mainly on the ACS framework research, focusing in the noti cation system to continue with ZeroMQ learning, especially the Publisher- Subscriber pattern as an ACS Noti cation Channel implement. Besides, a generic example is developed ful lling some requirements next to certain inconvenient identi cation and solution. Lastly, performance metrics are obtain from test execution which are compared with noti cation channel measurement, thus get conclusions from the results and hypothesis.
