摘要

The problem of real-time communication over a multiple access network has been well studied in the recent past. However, there are very few protocols that can bound the worst case channel access time to ensure predictability of message transmission for the LAN environment. In addition, there has been no prior work addressing real--time communication over a switched (extended) local area network (SLAN), where several LAN segments are connected through a switch. In this paper, we propose real-time protocols for the LAN and the SLAN. The proposed protocols are based on CSMAjCD with deterministic collision resolution and belong to the dynamic planning based category, where an admission test is performed for guaranteeing message transmission. The admission test used in the proposed protocols is based on the worst case channel access time that can elapse before a particular node can start transmitting its message. We also compute the worst case buffer requirement at the switch for the proposed SLAN protocols. We study the effectiveness of the proposed protocols through extensive simulation studies.
