This course covers MPLS and H.248 (MEGACO). The next generation of telecommunications networks will be deployed using VoIP technology and soft switching replacing circuit switching and ISDN signaling. By deploying communications as multimedia streams over IP it is possible to extend the services from simple voice to improved voice quality, better bandwidth utilization and expanded services into video and television carried over the same technology. Already cost effective VoIP services have been deployed using H.323 and SIP over Intranet infrastructures. However to integrate this with existing ISDN and SS7 architectures and eventually to replace local exchanges and transit exchanges in carrier networks requires large scale signaling and switching changes.
The next generation of telecommunications networks is likely to use IP and for efficient and high-speed quality of service switching deploy MPLS to select routes.
To build soft switches and distribute the switching function over a carrier level infrastructure, gateways will be controlled using H.248, called Media Gateway Control Protocol (MEGACO) by the Internet community.
