For each of the communication modes, there is an interface that makes the upper layers of the network independent.
EDITRAN can transmit simultaneously with different sessions that can use different interfaces, using the network and transport protocol TCP/IP.
Given the existing sensitivity to connect the machines where the corporate applications are running to internet public networks, we have developed a middle connection element among these corporate machines and public networks.
This middle connection element is place in the network DMZ and it provides the tranquility ot not having to expose the application files in a public network. It also simplifies the treatment of the firewall rules, as they don't need to be modified each time a new extreme node wants to connect our EDITRAN by TCP/IP.
