One of the major problems of Delay Tolerant Network (DTN) is the absence of complete path in between the source and destination. In the open literature, these networks are known as challenged network/Intermittently Connected Networks (ICNs). The existing protocols fail to operate properly in the context of intermittently connected network, which raises a variety of new challenging problems. This paper sheds the light over the architectural aspects of these networks. Here architectural aspects includes specification, working concept, required modification in traditional protocol, necessary included services etc.
