**5.1 Description of simulation**

This section will describe in detail, and scenario by scenario, all relevant events in each simulation, details on the movement of the AMN will be presented, the moments of reserve of resources through RSVP and some comments on the transfer; not without mentioning that for all scenarios a FTP traffic type was used and the following metrics of QoS were defined:

Delay, jitter, throughput, TCP congestion window and lost packets. The choice of the afore mentioned metrics is because they are the most affected when the amount of network traffic is very high, in addition these are the metrics that affect more significantly the traffics that have high QoS requirements such as video, audio and real-time applications.

It is noted once again that scenarios with different number of nodes were simulated to study the impact of this change in the behavior of the proposed integration compared to the QoS metrics and to evaluate the functionality of the proposed integration to such scenarios.

defined:

At the initial instant the mobile node (AMN) is in the area of its home agent (AHA) as shown in Figure 29, then at t = 1.2s the AMN starts transferring FTP traffic with the ACN, there upon between t = 3.5s and t = 4.5s MPLS / RSVP resource reservation takes place on the path MAP/GW1 - LSR2 - PAR/LER1. Then at time t = 10s the AMN begins its displacement towards the PAR/LER1, at a speed of 100m / s arriving shortly to this area from which it will use the PAR/LER1 - LSR2 - MAP / GW1 - AN1 route to communicate.

A few seconds later between t = 14.5s and t = 15.5s resource reservation along the route MAP/GW1 - LSR3 - NAR/LER2 takes place anticipating the subsequent transfer made by the AMN which moves at 10m / s from PAR/LER1 toward the NAR/LER2 at t = 16s. From there on, the traffic will follow the NAR/LER2 - LSR3 - MAP/GW1 - AN1 route to communicate with the ACN and the AHA. This is illustrated in the figure 32.
