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

In this work, we present a method to analyze greedy shapers, and we embed this analysis method into a well-established modular performance analysis framework. The presented approach enables system-level performance analysis of complete systems with greedy shapers, and we prove its applicability by analyzing two case study systems.
