This paper presents the results of an experimental activity concerning the implementation and validation of an EF-PHB service in a high-speed metropolitan optical network with a Differentiated Services architecture. As EF-PHB can be used to create low loss, low latency and assured bandwidth set-vices, real-time time traffic flows have been aggregated and classified as EF. Measurements have been performed in different operating conditions to evaluate how the setting of the EF class of service parameters affects the time metrics of each traffic How belonging to the aggregate. The transfer delay and the delay variation values, as specified by the ITU-T recommendation Y.1541 for real-time, jitter sensitive applications, have been taken as QoS performance objectives to satisfy.

Abstract

This paper presents the results of an experimental activity concerning the implementation and validation of an EF-PHB service in a high-speed metropolitan optical network with a Differentiated Services architecture. As EF-PHB can be used to create low loss, low latency and assured bandwidth set-vices, real-time time traffic flows have been aggregated and classified as EF. Measurements have been performed in different operating conditions to evaluate how the setting of the EF class of service parameters affects the time metrics of each traffic How belonging to the aggregate. The transfer delay and the delay variation values, as specified by the ITU-T recommendation Y.1541 for real-time, jitter sensitive applications, have been taken as QoS performance objectives to satisfy.
