    6666'''3.1 Comparison of Reno and CUBIC: [[BR]]'''
    6767 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 available congestion control''. [[BR]]

    6969 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]]
    7070 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 congestion control''. For example, to configure a host to use the Reno algorithm, use:
