The used virtualisation platform in our approach is OpenStack environment [12].
In order to integrate the ICN/CCN concept in the virtualized LTE, several options can be identified.
Five main different possible options are distinguished in [11], that can integrate the ICN/CCN concept in the user plane of RAN and EPC.
In the provided approaches, it is assumed that UE is not aware of the CCN
concept.
Therefore, a proxy functionality is required to intercept and translate the request message sent by a UE to a CCN message, and vice-versa. Another assumption is that, servers that deliver the content are CCNx capable.
The five main possible options are as follows:
