Design, implementation and performance analysis of the PROFIBUS/ATM Local Bridge

Building an interconnection between PROFIBUS and ATM networks

“…Since the details of learning and transferring sub-processes were given in Ozcelik and Ekiz (2004), we will give only flow diagrams of the processes in both sides (PROFIBUS to ATM and ATM to PROFIBUS) and functions of bridge entities. PROFIBUS to ATM process time flow diagrams and ATM to PROFIBUS process time flow diagrams are shown in Figs.…”

“…ATM provides different classes of services depending upon application type: data, voice and video. Since the applications considered in this study include only data communication, AAL-3/4 class of service is enough to fulfill all necessities to interconnect the PROFIBUS and the ATM LANs (Ozcelik and Ekiz, 2004).…”

“…The process model of transparent-translating bridge and layered architecture of the designed bridge are given in Ozcelik and Ekiz (2004).…”

Interconnection of CAN segments through IEEE 802.16 wireless MAN

“…Since Ekiz et al (1996a, b), Eltze (1997) and Tenruh et al (1999Tenruh et al ( , 2000 point out only overcoming distance limitation locally, they do not provide an exact solution to aforementioned problems above. Employing a backbone (e.g., an ATM) with a large amount of bandwidth to interconnect CAN networks (or fieldbuses) is one of the solutions to overcome this problem (Ozcelik et al, 2002(Ozcelik et al, , 2001Stipidis et al, 1998;Kunert and Zitterbart, 1997;Ozcelik and Ekiz, 2004). There may be certain difficulties in some industrial scenarios where a traditional wired backbone is deployed to provide these types of required interconnection functions.…”

Extending CAN segments with IEEE 802.11 WLAN

“…Internetworking Units (IUs) are high-performance devices that are used to interconnect similar or dissimilar LANs. While a pass-through forwarding process is sufficient for the interconnection of similar LANs, both a translation process and a forwarding process are required for the interconnection of dissimilar LANs [14]. In this study, the proposed Wireless Internetworking Unit (WIU) interconnects two CAN2.0A segments communicating through an IEEE 802.11 b; therefore, both the translation and forwarding processes are required.…”
