Optimization of the Scheduler for the Non-Blocking High-Capacity Router

The sequential greedy scheduling (SGS) is a scalable maximal matching algorithm that provides non-blocking in an Internet router with input buffers and a cross-bar. In this paper, we will present the FPGA design of the SGS scheduler. We have optimized scheduler components, and we will prove their correct functioning. The scheduler optimization significantly reduces the worst-case packet delay through the router.
