Psaras & Tsaoussidis (2009) On the properties of an adaptive TCP Minimum RTO (ComCom)

December 9, 2011 paper

RFC2988 says the minRTO should be 1 sec. The reason for that is due to two reasons: (1) clock granularity of the OS at that time, and (2) delay ack implementation is 200ms. [more]

Zheng & Qiao (2011) An Effective Approach to Preventing TCP Incast Throughput Collapse for Data Center Networks (GLOBECOM)

December 7, 2011 paper

This paper proposes an application-layer control on the number of concurrent senders in an incast application. The ideal number of concurrent senders is computed using the SRU, RTT and bottleneck buffer size. The paper assumes these parameters are available to the incast application. [more]

Ford et al (2011) TCP Extensions for Multipath Operation with Multiple Addresses (Internet Draft)

December 6, 2011 paper

The internet draft of MPTCP. MPTCP is a layer above TCP, so that the data stream from application is delivered by multiple TCP streams at the transport layer. The MPTCP layer is to merge the TCP streams into one stream, and deliver it to the application. [more]
