Once eWAN is deployed, two networks are deployed on the same time. The first is the control network which coincides with the previous network, the cluster network. EWAN gives the access possibility to all the nodes using the control network for the user comfort. With this option, the user can access a node without any gateway, and any machine is the center of all the connections. But this option allows also direct connection between the physical nodes and offers the possibility to work without the deployed topology.

EWAN would force the use of the correct topology and to use it correctly the user must contact the nodes with the correct IP.

The second problem is that the graphical part has a web page with a list of used machines with the emulated node and its ips, and a graphical representation of the topology. But it is not easy to do all the time the nodeIP nodeNAME connection.

For these two reasons eWAN will give an automatic translation nodeNAME nodeIP in each node of the deployed topology. With this the user can use the names which he knows:

ping client032
ssh router2
...

Additionally, for a best comprehension, each deployed node has a new hostname, (for example client3) which appears on the prompt when the user connects to the client.
