Token passing local area networks: A success story for standards

This paper presents the software architecture and the software development approach used by Concord Data Systems (CDS) for the development of their IEEE 802.4 standard token passing local area network products. The paper also describes the design goals and features of the CDS implementation of the ISO transport protocol. The transport implementation features a flexible interface that supports, ...

IP Multicast over Token-Ring Local Area Networks

IP multicasting provides a means of transmitting IP datagrams to a group of hosts. A group IP address is used as the destination address in the IP datagram as documented in STD 5, RFC 1112 [1]. These group addresses, also referred to as Class D addresses, fall in the range from 224.0.0.0 to 239.255.255.255. A standard method of mapping IP multicast addresses to media types such as ethernet and ...

Analysis of the PROFIBUS Token Passing over Wireless Links

Stability of Token Passing

Suucient stability condition for the standard token passing ring is "known" since the seminal paper of Kuehn in 1979. However, this condition was derived without formal proof, and the proof seems to be of considerable interest to research community. In fact, Watson observed that in the performance evaluation of token passing rings "it is convenient to derive stability conditions ... (without pr...

Virtual Token-passing Ethernet – Vtpe

The amount of information that must be exchanged in modern Digital Computer Control Systems (DCCS) and real-time industrial automation is now reaching the limits that are achievable with traditional fieldbuses. Currently, Ethernet is increasingly used in DCCS, however, the available solutions to guarantee real-time behaviour in Ethernet are not well suited to support the DCCS requirements and c...
