Zusammenfassung
Dieser Beitrag untersucht die Eignung der in XTP (Xpress Transfer Protocol) eingesetzten Protokollfunktionalitäten zur Kommunikation von Audio- und Videodaten. Ausgehend von den Anforderungen multimedialer Anwendungen werden die vorhandenen XTP-Mechanismen kurz erläutert. Anschließend werden für die wichtigsten Teilaspekte des Kommunikationsprotokolls (Verbindungsmanagement, Prioritätssteuerung,Flußsteuerung etc.) jeweils im Einzelnen die Anforderung von Seiten der Übertragung kontinuierlicher Medien und mögliche Lösungen im Kontext von XTP diskutiert. Es zeigt sich, daß zur Unterstützung multimedialer Kommunikationsformen sowohl geeignete Interpretationen vorhandener XTP-Protokollmechanismen wie auch Protokollerweiterungen erforderlich sind.
Abstract
This paper analyzes the requirements of multimedia communications in terms of XTP (Xpress Transfer Protocol). In a first step, multimedia communication requirements are described. Subsequently individual features of XTP relevant for audio and video data transfer are presented. We describe the multimedia requirements and provide a possible way to satisfy them using XTP. It turns out that a multimedia capable XTP requires new interpretations of existing mechanisms as well as some extensions.
