VoIP – Modern Telecommunication Networks
VoIP – Modern Telecommunication Networks

(16 hours)

Today there is a drive to enable voice networks with an intelligent control plane based on an evolution of IP and MPLS protocols. Such optical/IP internetworking will dramatically reduce the costs of operating these networks and will enable service providers to create more dynamic new services for their customers. Voice over MPLS (Multi Protocol Label Switching) is one of the most innovative data networking technologies to emerge since the rise of the Internet. MPLS is a rich, full-featured networking technology that provides benefits to enterprises and carriers alike. This course looks at the subject of MPLS and optical networks. Participants will see how it works, as well as look at some of the applications of MPLS.
