Zhang et al (2011) Modeling and Understanding TCP Incast in Data Center Networks (INFOCOM)

July 20, 2011 paper

This paper gives two reasons for incast, namely, block tail time out (BTTO) and block head time out (BHTO). The former is about the lost of one of the several last packet, which cannot produce enough dupack to signal fast retransmit; the latter is about the lost of whole window... [more]

Zhang et al (2011) Shrinking MTU to Mitigate TCP Incast Throughput Collapse in Data Center Networks (ICCMC)

July 20, 2011 paper

A short paper that proposes to use a smaller MTU to solve the incast problem. As the buffer size is fixed, a smaller packet means the buffer can hold more packets, and then it allows the TCP window to be “larger”. A larger TCP window is easier to catch packet... [more]
