Evaluation of the communication latency over real-time channel in HARTS

초록

In this paper, the end-to-end communication latency in HARTS(Hexagonal Architecture for Real-time Systems) is evaluated, wwhich depends on the intra-node delay as well as the inter-node delay. While the inter-node delay is bounded due to the point-to-point real-time channel, the intra-node delay is variable according to the message traffic and the internal structure of a HARTS node. The intra-node delay is evauated analytically and by computer simulation for the various implementational models.
