“…In the last few years there has been an increasing interest in migrating industrial networks from specific technologies to Ethernet (Skeie et al, 2006;Krommenacker et al, 2001Krommenacker et al, , 2002Lee et al, 2006;Skeie and Johanssen, 2002;Rüping et al, 1999;Georges et al, 2006;Erturk, 2005;Silvestre and Sempere, 2007;Ö zcelik and Ekiz, 2007;Cena et al, 2008;Zhang and Zhang, 2007;Ferrari et al, 2006). Specific technologies currently used, called fieldbuses, such as FIP or Profibus (Georges et al, 2006;Erturk, 2005;Silvestre and Sempere, 2007;Ö zcelik and Ekiz, 2007) are deterministic networks which try to ensure end-to-end delays of messages remain limited.…”
