摘要：
In the "many-to-one" concurrent traffic pattern of the data center networks, TCP(Transmission Control Protocol) and its existing improvements have low throughput in single-round and multi-round of data transmission scenarios. Hence, a strategy called TSL(TCP SkyLine) is proposed for fast discovering and retransmitting the lost packets through packet labelling and adjusting the initial size of the congestion window dynamically. TSL solves the traditional TCP Incast problem and the TCP Incast problem caused by the legacy window in multi-round of data transmission. Through extensive experiments we show that TSL can achieve more than 90% goodput regardless of single or multiple rounds of data transmission. In a 10Gbps network, the number of concurrent connections supported by TSL has increased by 5 times and once respectively compared to the traditional TCP and DCTCP, and the goodput has increased by 18 times and 8.6 times respectively. In a 1Gbps network, the number of concurrent connections supported by TSL has increased by 5.8 times and once respectively compared to the traditional TCP and DCTCP. © 2020, Chinese Institute of Electronics.
