Dear all: I'm reading the code about the Congestion Control.Now I'm confused about the variable "reord" in the function tcp_sacktag_write_queue().
The "reord" is initialized as the tp->packets_out, I think, which is a max threshold of the reordering. If it detect a hole or D-SACK ,set the reord to : ---> reord = min(fack_count, reord); Finally,the code may update the reordering by: ---> tcp_update_reordering(sk, ((tp->fackets_out + 1) - reord), 0); The questions are : <1> What's the purpose of the "reord" ? <2> Why use the "((tp->fackets_out + 1) - reord)" to update the reordering. Do I need to study some more RFC about this ? If yes,please tell me ,thanks . - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
