TCP Pacing in Data Center Networks

Monia Ghobadi, Yashar Ganjali
2013 2013 IEEE 21st Annual Symposium on High-Performance Interconnects

Optimizing data transfer nodes using packet pacing

Nathan Hanford, Brian Tierney, Dipak Ghosal
2015 Proceedings of the Second Workshop on Innovating the Network for Data-Intensive Science - INDIS '15  
An important performance problem that we foresee with Data Transfer Nodes (DTNs) in the near future is a fast sending host over-running a slow receiving host, and packets getting dropped, leading to poor  ...  We also describe the results of several experiments to test the feasibility of such a solution, and in doing so are able to present some of the bounds of flow pacing at these line rates.  ...  TCP Flow Pacing Burstiness in network traffic can lead to packet loss which can cause reduced TCP throughput significantly in highspeed networks with large RTTs.  ...
