ns gpsr路由协议 在ns２平台下实现的 对大家很有好处

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 at

bdflow_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 flows

to 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 interval

avgpktdrop.awk just calculates the average packet drop rate from the fairflow.tr trace file generated by bdflow.tcl

fm_stats.fmt just displays the flowmon output format
