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).
