Hi,
I have a remark about the RFC 3042 code that is implemented in
tcp_input.c (CVS version 1.281.2.2). When a duplicate ack comes in, the
code saves the congestion window (cwnd), changes it to allow one packet
to be sent, and then calls tcp_output().
Is there a reason for not saving the bandwidth window (bwnd), and
changing it to the same value as cwnd ? I have a case (half duplex
link), where the bwnd is at its lowest value (6144), preventing the
limited transmit to occur (i.e. tcp_output does not send any packet
because bwnd forces sendwin to a value that is lower than cwnd).
David
