Improving the Incast Performance of Datacenter TCP by Using Rate-Based Congestion Control Jingyuan WANG Yunjing JIANG Chao LI Yuanxin OUYANG Zhang XIONG Publication IEICE TRANSACTIONS on Fundamentals of Electronics, Communications and Computer Sciences Vol.E97-A No.7 pp.1654-1658 Publication Date: 2014/07/01 Online ISSN: 1745-1337 DOI: 10.1587/transfun.E97.A.1654 Type of Manuscript: LETTER Category: Communications Environment and Ethics Keyword: datacenter, rate-based, TCP congestion control, Full Text: PDF>>
Summary: We analyze the defects of window-based TCP algorithm in datacenter networks and propose Rate-based Datacenter TCP (RDT) algorithm in this paper. The RDT algorithm combines rate-based congestion control technology with ECN (Explicit Congestion Notification) mechanism of DCTCP. The experiments in NS2 show that RDT has a potential to completely avoid TCP incast collapse in datacenters and inherit the low latency advantages of DCTCP. | |||||
