v12 v13 66 66 '''3.1 Comparison of Reno and CUBIC: [[BR]]''' 67 67 GENI nodes provide two TCP congestion control algorithms, CUBIC and Reno, that can be chosen at run-time. [[BR]] 68 The list of available algorithms are listed in the file ''/proc/sys/net/ipv4/tcp availablecongestion control''. [[BR]]68 The list of available algorithms are listed in the file ''/proc/sys/net/ipv4/tcp_available_congestion control''. [[BR]] 69 69 The “Reno” congestion control provided by the Linux kernel is actually the [http://tools.ietf.org/html/rfc3782 NewReno] algorithm, but we will refer to it as Reno here to be consistent with Linux terminology. [[BR]] 70 70 Note that congestion control actions are very similar between Reno and [http://tools.ietf.org/html/rfc3782 NewReno], but [http://tools.ietf.org/html/rfc3782 NewReno] has a more nuanced approach to loss recovery.. [[BR]] 71 These congestion control algorithms can be chosen by placing the keywords ''reno'' or ''cubic'' in the file ''/proc/sys/net/ipv4/tcp congestioncontrol''. For example, to configure a host to use the Reno algorithm, use:71 These congestion control algorithms can be chosen by placing the keywords ''reno'' or ''cubic'' in the file ''/proc/sys/net/ipv4/tcp_congestion_control''.
