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).
