Converged Network Architectures

Converged Network Architectures

Konvergente Netzwerke ermöglichen die Integration von Sprach-, Video- und Datentransport auf einem einzigen Netzwerk. Die Vorteile liegen klar auf der Hand: Kostensenkung, Unterstützung von ausgefeilten, integrierten Anwendungen sowie größere Netzwerkflexibilität und -funktionalität. Dieses Buch schließt eine Lücke in der aktuellen Literatur zum Thema Konvergenz. Es behandelt alle wichtigen Netzwerkarchitekturen und die neuesten Enabling Protocols, wie SIP, H.323, MPLS und H.248 - um nur einige zu nennen. "Converged Network Architectures" gibt Netzwerkdesignern und -managern einen kompletten Überblick über die benötigten Strukturen und Komponenten. Darüber hinaus hilft der Band, Netzwerkarchitekturen und Protokolle wie SONET, Frame Relay, ATM und IP besser zu verstehen. "Converged Network Architectures" - Hier lernen Sie, mit konvergenten Netzen ein Maximum an Service zu einem Minimum an Kosten zu schaffen. Eine nützliche Lektüre für die Praxis!
