Get the big picture on converged network architectures and emerging protocols! Converged networks integrate voice, video, and data traffic on a single network. This book covers converged network architectures as well as the latest enabling protocols including SIP, H.323, MPLS, and H.248. Readers will gain a better understanding of network architectures and protocols such as SONET, frame relay, ATM and IP. The book offers the latest information on voice communication networks, data networks, voice packet processing, coding for broadband systems, and voice- over packet networks. Readers will also discover how converged networks can provide the highest level of service for the least cost.
