Traffic Modeling in Industrial Ethernet Networks

Support Industrial Hard Real-Time Traffic with Switched Ethernet

This paper presents a simple and efficient switched Ethernet communication protocol for industrial hard real-time LAN applications. The network is founded with end nodes and a switch, and hard real-time communication is handled by software added between the Ethernet protocols and the TCP/IP suites. We established a virtual link of the source and destination node by applying admission control ba...

Security in Industrial Ethernet

Ethernet has become increasingly popular in automation, due to its easy integration with other networks but also for its low costs and commercial availability. Characteristics like real-time capabilities required in automation have also been added and now form Industrial Ethernet allowing its deployment in application areas formerly reserved for dedicated fieldbus systems. Due to the vertical i...

High Priority Traffic Separation in Shared Ethernet Networks

In this paper, it is proposed an enhanced algorithm for the collision resolution in shared Ethernet networks. Such algorithm, referred as high priority Binary Exponential Backoff (h-BEB), provides high priority traffic separation, enabling the support of real-time communications. To our best knowledge, the h-BEB algorithm is the first collision resolution algorithm that allows Ethernet standard...
