In the last decade, cluster computing has become the most popular high-performance computing architecture. Although numerous technological innovations have been proposed to improve the interconnection of nodes, many clusters still rely on commodity Ethernet hardware to implement message passing within parallel applications. We present Open-MX, an open-source message passing stack over generic E...

Ethernet is being applied to the Local Area Network field due to its low cost, and easy installation and operation. Because IP centric communication has been adopted widely, a recent trend is the application of Ethernet to Wide Area Networks to form the transport networks needed for IP communication. For example, recent optical access networks for FTTH and leased line networks for business user...

The initial iSCSI products provide a means to connect FC SAN islands across IP networks. This paper describes the implementation of an IP-SAN where the disk subsystem is a virtual array of individually Ethernet attached IP-addressable disks. By replacing the conventional peripheral bus and loop interconnects with a switched Gigabit Ethernet network, the virtual disk array scales continually and...

With a standard bridged Ethernet network, a possible delay of high-priority packets by lower-priority packets that are just being served within a bridge or device cannot be avoided. The results are higher transaction times and jitter values, especially when using long chains of bridges. With this characteristic, Ethernet cannot be used in timecritical synchronous applications. In this paper we ...

In this paper, we present a probabilistic admission control algorithm over switched Ethernet to support soft real-time control applications with heterogeneous periodic flows. Our approach is purely end host based, and it enables real-time application-to-application QoS management over switched Ethernet without sophisticated packet scheduling or resource reservation mechanisms in Ethernet switch...

Ethernet bridging in campus networks offers advantages like zero configuration, no need of IP addresses administration in subnets, high performance and low costs. But Ethernet bridging does not scale. Current proposals under standardization, like Shortest Path Bridges and Routing Bridges use a link-state routing protocol to compute shortest paths. As a simpler alternative, we propose an evoluti...

System administrators often assume that just by plugging in a Gigabit Ethernet Interface, the system will deliver line rate performance; sadly this is not often the case. The behaviour of various 1 and 10 Gigabit Ethernet Network Interface cards has been investigated using server quality motherboards. The latency, throughput, and the activity on the PCI buses and Gigabit Ethernet links were cho...

Ethernet continues to be one of the most popular LAN technologies. Due to the low price and robustness resulting from its wide acceptance and deployment, there has been an attempt to build Ethernet-based real-time control networks for manufacturing automation. However, it is di cult to build a realtime control network using the standard UDP or TCP/IP and Ethernet, because the Ethernet MAC proto...

|In der industriellen Automatisierung setzt sich die Ethernet-Kommunikation immer mehr durch. Die Entscheidung, welches Industrieprotokoll für welche Architekturebene am besten geeignet ist, liegt jedoch noch beim Nutzer.

In this paper we show, under which conditions switched ethernet can be called deterministic.The influence of the service strategies in switched ethernet is investigated by simulation and compared with analytical bounds on the delays.
