Redes de computadores from edX

Las redes de computadores, o renombradas hoy en día como Networks of Things , son esenciales para soportar los servicios de Internet que usamos a diario, dado que soportan la transformación digital de las empresas y apalancan de manera directa la revolución 4.0 que vivimos hoy en día.

Entender el funcionamiento de las redes de computadores es fundamental para poder iniciarse en roles orientados al diseño, implementación y mantenimiento de redes corporativas, y sin duda también representa un conocimiento diferencial para poder optar por uno de los denominados empleos de la cuarta revolución industrial que incluyen: Especialistas en Big Data, Especialistas en transformación digital, Desarrolladores y analistas de software y aplicaciones, gestor de servicios de TI, entre otros.

Este curso te enseñará los conceptos claves y herramientas que te ayudarán a entender mejor la forma como funcionan las redes de computadores, realizando un entendimiento de la arquitectura más utilizada en internet (TCP/IP) y haciendo una revisión de los protocolos más importantes de cada una de las capas de dicha arquitectura. Las redes inalámbricas también serán incluidas como parte del temario del curso por su importancia hoy en día en el despliegue de soluciones de tipo smart home donde se tienen múltiples equipos conectados a internet ofreciendo y consumiendo información. Adicionalmente, se apropiarán algunos conceptos de seguridad de redes para asegurar las redes corporativas a través de diferentes mecanismos de protección como VLANs y Firewalls.

Dentro de los laboratorios a implementar se encuentran: cálculo del Throughput, inspección de mensajes del protocolo HTTP, implementación de sockets TCP y UDP, cálculo de direccionamiento IP, configuración de un servicio DHCP, implementación de rutas estáticas y dinámicas, prueba del protocolo ARP, configuración de una red inalámbrica, implementación de VLANs, entre otros. Para el desarrollo de estos laboratorios se utilizará software libre, por ejemplo el monitor de tráfico Wireshark que permite revisar la estructura de los paquetes en una red. Por otro lado también se utilizará software de simulación de redes de uso gratuito, por ejemplo el simulador Packet Tracer del proveedor de telecomunicaciones CISCO.

Aprende a través de una metodología de enseñanza dinámica ofrecida desde la Escuela de Ingeniería, Ciencia y Tecnología de la Universidad del Rosario, la cual explica los conceptos teóricos de una manera precisa y posteriormente los pone en práctica a través de los laboratorios, sin necesidad de implementar infraestructura compleja o costosa. El estudiante también puede optar por presentar test al final de cada módulo los cuales le permitirán validar y afianzar el conocimiento adquirido.
