Executive Summary

Ethernet is becoming the dominant data transmission technology for service providers due to its simplicity and low cost. However, the need for Quality of Service (QoS) provisioning for some time-sensitive applications drives the definition of new functionalities in Ethernet. In this work the author's addresses QoS in Ethernet by introducing a time synchronization capability at MAC level while maintaining it's asynchronous and distributed architecture. This paper presents a reconfigurable logic platform based on a Field Programmable Gate Array (FPGA) in which the authors embed the custom Time Stamping Unit (TSU).
