There are a large number of sharks available for use in Testbed experiments. Unfortunately, the sharks are greatly limited in their topology. Sharks can only be used in groups of up to 8, connected to each other via a 10Mb, no delay, no loss LAN, with a single link to the rest of the topology.
To use sharks in your experiment just set them up as normal nodes.
Sharks must be in a LAN and there can be at most 8 sharks in any one
LAN.
Use tb-set-hardware
to set them to type
shark
.
Example:
source tb_compat.tcl set ns [new Simulator] set s1 [$ns node] set s2 [$ns node] set s3 [$ns node] set s4 [$ns node] set n1 [$ns node] tb-set-hardware $s1 shark tb-set-hardware $s2 shark tb-set-hardware $s3 shark tb-set-hardware $s4 shark set slan [$ns make-lan "$s1 $s2 $s3 $s4 $n1" 10Mb 0ms] tb-set-ip-lan $s1 $slan 1.2.3.100 tb-set-ip-lan $s2 $slan 1.2.3.101 $ns run
