The rst thing to note is that the worst performing paradigm is the LG paradigm, followed by the
NB paradigm. The CB paradigm clearly outperforms the other two.
In the case of the LG paradigm, there is no route optimization and, thus, this leads to very poor
RTT performance. Note that the extremely high RTT values result from the fact that several sce-
narios comprise various levels of nesting. This will be further addressed later, in the subsection on
level of nesting analysis.
By introducing route optimization, the NB paradigm signicantly reduces the average RTT. As
the load increases ...
