A Congestion Control Mechanism for Data Center Networks Based on Named Data Networking

Abstract

Data center networks have become important infrastructures in cloud computing. TCP Incast is a common challenge for data center networks. Although many researchers have tried to address this issue, there is no optimal solution yet. In this paper, different from current effort in IP networks, we try to mitigate the TCP Incast issue by innovatively adopting a new network architecture-Named Data Networking (NDN). Taking advantage of the receiver-driven transfer model and the in-network caching mechanism of NDN, we propose a novel packet request algorithm which can avoid the congestion and we have implemented the algorithm in ndnSIM. Simulation results show that our algorithm can mitigate the TCP Incast issue effectively.
