Paper Abstract:
|
TCP provides the reliable data transfer over the Internet against various types of transmission errors. Recently, packet losses can be caused by transmission interruptions such as handoffs in the mobile networks and protection switching in the transport networks. These packet losses are bursty because the transmission interruptions continue for tens of miliseconds through several seconds. Previously, we performed the experimental analysis for various TCP versions running on Linux, Windows and MAC OS, and found that, although TCPs in Linux and Windows 7 recover from bursty losses quickly, TCP in OS X shows an intermittent data transfer during the timeout retransmission invoked by bursty losses, which takes several seconds for retransmitting all of the lost packets. In this paper, we give detailed results of experimental analysis. Based on this analysis, we clarify the reason for the intermittent data transfer in MAC OS X by taking account of newly introduced TCP procedures, such as F-RTO and Early Restansmit. |
