Flat IP architecture provides a way to identify devices using symbolic names, unlike the hierarchical architecture such as that used in “normal” IP addresses. This form of system is of more interest to mobile broadband network operators.
Names are assigned as a sequence of symbols that are interpreted as a single, whole label without any internal structure. There is no clear relationship between any name and any other name.
The main idea of a name system is to provide a way to identify devices using symbolic names. Like any identification mechanism, before we can use the system we must define the way that identification will be performed. Numeric addressing schemes (like IP addresses) have rules for how addresses are created, and assign addresses to each device from their address space. In a similar way, devices in a name system are given names from the system’s name space.
Name Space Functions
An example of this sort of architecture would be a name system where computers are given unstructured names like Enodeb1, Enodeb2 , MME1, MME2 etc.
