Do we have a Similar tcl file?

Hi,

A very Good day to you,


S1___________R1____________R2............................D1       (RI-R2
Wired link 200Mbps, 25ms;  R2-D1Wireless link 5ms)



  S1-R1
Wired Link(1Gbps, Tms)

Please I would like to know if I can find a similar topology with the one
above  or if someone is willing to share.
It consist of a wired link from a source S1 or a number of source which is
connected to a router ( bottleneck). The router R1 is connected to another
router R2 via a wired link. R2 is connected to D1 or a number of
destinations via a wireless link.

I will also appreciate where can I get the following TCP variants (CUBIC
TCP, HSTCP, WESTWOOD AND BIC)


Thank you
