This is a ns-3 simulator of paper Poseidon: Efficient, Robust, and Practical Datacenter CC via Deployable INT from NSDI 2023. It also includes the implementation of HPCC, DCQCN, TIMELY, DCTCP, PFC, ECN and Broadcom shared buffer switch. Our code is based on the simulator for PINT and HPCC.

Please refer to the README.md under simulation folder for more details.

This repo is under active development by Weitao Wang, any questions are welcome through the repo issues or emails.

In Poseidon paper, we use a different simulator, which is a Google internal packet-level simulator. Poseidon paper also constructes a testbed with Tofino2 switches. For implementation details of the testbed, please also contact Weitao ([email protected]).

If you compare with Poseidon or use the Poseidon algorithm in a scientific publication, please cite the following paper:
