    El Concepto “Software-defined Network” 4

    edu.red Software Defined Networking (SDN)

    Los principales objetivos de SDN Abstraer los elementos de la Red desde las Aplicaciones. Control y Gestión centralizadad de los dispositivos de red de diferentes fabricantes. Tener una Red abierta que permita ser programable y crear servicios de forma sencilla. SDN es una arquitectura que divide el plano de conmutación y permite que sea programable de una forma directa.

    LAS REDES ABIERTAS ADOPTARAN MAYORES INNOVACIONES.

    edu.red Introducción aOpenflow

    edu.red Aproximación a openflow Plano de Control separado del plano de conmutación Plano de Control Centralizado. OpenFlow controller(La plataforma). Lógicamente centralizada y fisicamente distribuida.

    Plano de conmutación distribuido. OpenFlow switches (Pueden ser routers,firewalls). No es necesario tener protocolos de routing . Software (kernel, hypervisor, userspace), Hardware (merchant silicon, ASICs, OpenFlow optimized ASICs) OpenFlow es el protocolo entre el plano de control y de conmutación.
