33.3.1.0.1 Nodes and Links

The node contains only its node id and the port number for the next agent. A link only contains the values of its bandwidth and delay.

    set did [\$n2 id]

    set bw\_(\$sid:\$did) [expr [string trimright \$bw Mb] * 1000000]
    set delay\_(\$sid:\$did) [expr [string trimright \$delay ms] * 0.001]
