      Add Agent/TCP and Agent/TCPSINK so that we can use Mike's new trafgen · d26d5035
      Leigh B. Stoller authored
      code in TCP mode. Simple changes. Works like this:
      
      	set tcp0 [new Agent/TCP]
      	$ns attach-agent $n2 $tcp0
      
      	set cbr1 [new Application/Traffic/CBR]
      	$cbr1 attach-agent $tcp0
      
      	set null1 [new Agent/TCPSINK]
      	$ns attach-agent $n3 $null1
      
      Note, there are no state variables supported yet.

      Initial version of RED/GRED support. Chris is going to have to finish · f35ce7e3
      Leigh B. Stoller authored
      this off, but here is what I did.
      
      Parser: Allow for the following syntax
      
      	set link0  [$ns duplex-link $nodeA $nodeB 100Mb 0ms RED]
      	set queue0 [[$ns link $nodeA $nodeB] queue]
      	$queue0 set gentle_ 1
      	$queue0 set queue-in-bytes_ 0
      	$queue0 set limit_ 50
      	$queue0 set maxthresh_ 20
      	$queue0 set thresh_ 7
      	$queue0 set linterm_ 11
      	$queue0 set q_weight_ 0.004
      
          NB: This differs from the NS syntax (and is the part that Chris
          needs to fix) in that there is just a single queue object per
          duplex link, thus the parameters cannot be set asymmetrically.
          Note, the delay node *does* use a RED/GRED queue in each
          direction, but its params are the same. These TCL hacks took a
          long time for me to get right!
      
          Also note that I have no idea how this stuff relates to LANS! I
          do not allow LANS to be created with RED queues (another item for
          Chris to work on perhaps?).
      
      assign_wrapper: A horrible hack to pass the new fields added to
      virt_lans onto the delays table setup. Also another minor hack ensure
      that a delay node is added when a RED queue is used (for the case when
      no other traffic shaping is done). At the moment, the virt_lans table
      has a single set of fields, while the delays table has the double set;
      one for each direction of the pipe. Here is a listing.
      
          alter table delays add q0_limit int default 0 after lossrate0;
          alter table delays add q0_maxthresh int default 0 after q0_limit;
          alter table delays add q0_minthresh int default 0 after q0_maxthresh;
          alter table delays add q0_weight float default 0.0 after q0_minthresh;
          alter table delays add q0_linterm int default 0 after q0_weight;
          alter table delays add q0_qinbytes tinyint default 0 after q0_linterm;
          alter table delays add q0_bytes tinyint default 0 after q0_qinbytes;
          alter table delays add q0_meanpsize int default 0 after q0_bytes;
          alter table delays add q0_wait int default 0 after q0_meanpsize;
          alter table delays add q0_setbit int default 0 after q0_wait;
          alter table delays add q0_droptail int default 0 after q0_setbit;
          alter table delays add q0_red tinyint default 0 after q0_droptail;
          alter table delays add q0_gentle tinyint default 0 after q0_red;
      
      tmcd/tmcd.c: Change dodelays to pass back all of these fields (for
      both pipes; there are equiv q1 fields in the delays table). Yikes! Its
      done in a backwards compatable manner though, so existing delay nodes
      will continue to work just fine.
      
      tmcd/freebsd/liblocsetup.pm: Change the delays configuration script to
      get all these fields and do something useful with. Of course, our
      delay nodes cannot use a lot of these fields, but the information is
      sent through for the eventuality that we have more sophisticated
      delays nodes.
      
      Test Suite: Add red test dir that has the above syntax as its test.

      Rename exports_setup.proxy and console_setup.proxy to .in versions and · 589d4872

      remove the originals, so that we can run the files through configure.
      
      NOTE: I wanted to keep the RCS history intact so I went over to the
      CVS directory on moab and copied the ,v file to the new names, and
      then did a normal cvs remove the originals. This keeps the RCS history
      going without screwing up anyone. Not a recommended approach, but what
      the hell.
