bdflow.tcl is almost exactly like flow4.tcl except it uses the Chernoff bound code in bound.tcl	in bdflow.tcl, the type of traffic and congested link is set in procedure add_traffic, in the command traffic_{Lbw{Lcg,Hcg},Hbw{Lcg,Hcg}}	the link capacities are set in the beginning of the file with "set highspeed_bw XMb" and "set bottleneck_bw YMb".  highspeed_bw is the bandwidth from nodes to routers and vice versa.  bottleneck_bw is the bandwidth from router to router.	procedures random_tcps and random_cbrs create n tcps or cbs and randomizes the start times.  the traffic is persistent.bound.tcl contains the procedure drop_bound which takes a probability, a constant c, a fraction of the arrival rate p, and the type of bound, and returns the number of drops to look atbdflow_h.tcl is almost exactly like Flows.tcl except it is the helper file for bdflow.tcl instead of flow4.tcl	in bdflow_h.tcl, procedure flowDump calculates the drop bound and dumps flowsto run bdflow.tcl do: "ns bdflow.tcl combined <seed>"output files generated are:	fairflow.tr - trace file from flowmon dump	fairflow.xgr.c - xgraph file for combined metric	fairflow.rpt.drop - drops vs interval	fairflow.rpt.sec - seconds vs intervalavgpktdrop.awk just calculates the average packet drop rate from the fairflow.tr trace file generated by bdflow.tclfm_stats.fmt just displays the flowmon output format
