Traffic shaping is a well-known technique in the area of networking and is proven to reduce global buffer requirements and end-to-end delays in networked systems. Due to these properties, shapers also play an increasingly important role in the design of multi-processor embedded systems that exhibit a considerable amount of on-chip traffic. Despite their growing importance in this area, no methods exist to analyze shapers in distributed embedded systems, and to incorporate them into a system-level performance analysis. Hence it is until now not possible to determine the effect of shapers to end-to-end delay guarantees or buffer requirements in these systems.
