Virtual Token-Passing Ethernet Proposal using Programmable Hardware

Francisco Borges CarreiroJosé Alberto FonsecaFrancisco Vasques

The Virtual Token-passing Ethernet (VTPE) is a real-time shared Ethernet approach based on an implicit token rotation principle known as virtual token-passing. The first VTPE version has been implemented in an 8 bit microcontroller using a standard Ethernet controller. The use of low processing power microcontroller and standard Ethernet controllers, despite of the low processing VTPE requirements, imposes limitations in the network efficiency throughput. This paper proposes a new implementation using programmable hardware (FPGA) having a physical transceiver as media interface, instead of a standard MAC controller. This proposal increases the throughput to the theoretical limits of Ethernet 10/100 Mbps.
