it shows that the proposed integration is functional in the presence of more than 9 nodes and also that the metrics in question do not deteriorate significantly in scenarios of large volumes of nodes. Another important fact to highlight is that performance observes a relationship of inverse proportion to the number of nodes that make up the simulation scenario that is to say, that with more nodes the performance decreases, however this decrease is not linear but it is less affected with the presence of new nodes. As the tendency is presented, it could be said that it is possible that for scenarios of more nodes performance will be stabilized around a certain value, which means that the decrease has a limit. The last fact to note is that the proportion of lost packets does not increase as the number of nodes increases, but stabilizes after some growth in the network. Therefore we can conclude that the proposed integration is useful for providing QoS in scenarios with large volumes of

In this figure 39 we can visualize the following metrics (Delay, Jitter, Throughput, Send and Lost Packets vs. Number nodes). The Delay, Jitter and Throughput have slight variation. The throughput decreases when increasing the number nodes, likewise the send packets decreases when increased the number nodes and traffic flow. This behavior of these metrics is logical, we did not test with more nodes, because we believe that these tests is enough to

This chapter released the results of the integration FHAMIPv6/MPLS and features to provide QoS. This study is of considerable importance because it is the first to bring mobile capabilities, fast handover and hierarchical IP extensions to MPLS hybrid environments. Thus provides the basis for future research that want to implement prototypes in real environments.
