Providing network bandwidth guarantees over an Ethernet requires coordination of the network nodes for traac prioritization such that real-time data can have deterministic access to the network. We have shown previously how RETHER, a software-only token passing protocol can eeciently provide real-time support over a single shared Ethernet segment. This work extends the token passing mechanism i...

The performance of network storage systems is often limited by overheads in the I/O path, such as memory copying, network access costs, and protocol overhead. As a result, I/O remains the bottleneck for high-performance data-intensive applications. This paper examines different communication transports and their effect on network storage system’s performance. To accomplish the proposed study, w...

Ethernet has been a cornerstone networking technology for over 30 years. During this time, Ethernet has been extended from a shared-channel broadcast network to include support for sophisticated packet switching. Its plug-and-play setup, easy management, and self-configuration capability are the keys that make it compelling for enterprise applications. Looking ahead at enterprise networking req...

The ethernet technology is used in multi-arc submerged arc welding systems communicate with each other. The structure of twin-arc high-speed SAW (Submerged arc welding) equipments based on Ethernet is proposed. The welding equipment technical requirement for Ethernet is discussed. The crucial implementations of Ethernet TCP / IP in the welding equipment is presented including designs of ARM (Ad...

With the recent IPv6, Power over Ethernet (PoE) and robust hardware designs, Switched Ethernet technology is currently reaching the status of a complete fieldbus system for harsh factory floor applications. However, the investors still hesitate on its field level operation for time critical applications, due to the non-deterministic delays in the closed world of a switched network. The objectiv...
