Software Realization of Network Off-line Scheduling with Time-Triggered Ethernet on the Basis of Response Constraint

Abstract

Time-Triggered Ethernet (TTE) is a new network communicational technic with Ethernet, which combines time service and event service. Reasonable time planning and schedule design enable three different types of traffic with various time-critical characteristics including Time-Triggered (TT) traffic, Rate-Constrained (RC) traffic and Best-Effort (BE) traffic to be transmitted regulated by their own rules and priority efficiently. This paper raises a method suited for generating TTE network off-line time schedule with response constraint. Also, this research introduces response constraint as an important consideration on the basis of existed hybrid traffic partitioning scheduling strategy. At the same time, the network schedule is used to form a composite schedule table strategy to simplify the schedule generation process. Furthermore, a software is designed to generate off-line schedule, and its rationality about generating schedule periodically is verified by practical examples.
