  • 1a21e49a8   [DCCP] ccid3: Finer-grained resolution of sending rates ... Browse Code »

    This patch
    * resolves a bug where packets smaller than 32/64 bytes resulted in sending rates of 0
    * supports all sending rates from 1/64 bytes/second up to 4Gbyte/second
    * simplifies the present overflow problems in calculations

    Current sending rate X and the cached value X_recv of the receiver-estimated
    sending rate are both scaled by 64 (2^6) in order to
    * cope with low sending rates (minimally 1 byte/second)
    * allow upgrading to use a packets-per-second implementation of CCID 3
    * avoid calculation errors due to integer arithmetic cut-off

    The patch implements a revised strategy from
    http://www.mail-archive.com/dccp@vger.kernel.org/msg01040.html

    The only difference with regard to that strategy is that t_ipi is already
    used in the calculation of the nofeedback timeout, which saves one division.
