High-fidelity link shaping

In this report, we have focused on three link shaping methods: hidden delay bridge, router rate limiting, and pause frames. The focus of the study was to determine which method produced the specified delay and bandwidth limit. In addition, the study also took into consideration variance of inter-packet gaps (jitter). To obtain the results, we have created a variety of constantUDP flows and compared the performance of the link shapingmethods with each other. The results revealed that the delay bridge using the Click modular router is superior to the other two methods.
