Literature review software defined networking for VoIP, SDN

Se realizó un análisis de implementaciones de redes SDN enfocándonos a redes con servicios VoIP. Se identificaron implementaciones con OpenFlow como base, así como implementaciones con enfoques de virtualizacion de servicios SIP. Actualmente, el uso de SDN con VoIP se utiliza para permitir un control de QoS y QoE de manera dinámica, eficaz y con bajo coste de implementación. Por último, se analizaron desarrollos de SDN enfocados a seguridad, CAC (Call Admisión Control) y enfoques a la gestión de recursos.An analysis of implementations of SDN networks was carried out, focusing on networks with VoIP services. Implementations with OpenFlow as a base were identified, as well as implementations with approaches to virtualization of SIP services. Currently the use of SDN with VoIP is used to allow QoS and QoE control in a dynamic, efficient way and with low implementation cost. Finally, SDN developments focused on security, CAC (Call Admission Control) and approaches to resource management were analyzed
