* forwarding: forwarding of packets has to be performed in both types
* routing: selection of a routing protocol and determination of the necessary parameters.
This leads to the fact that one can create an information model of a network element, based on the building blocks of a specific network element. The information model would define that a network element has 1 to n interfaces, where an interface has a name, an identifier, a hardware-address, 0 to m IP addresses etc.
This leads to the point that one can create an information model of a network element, based on the building blocks, i.e., made up of the network concepts, of a specific network element. The information model would define that a network element has 1 to n interfaces, where an interface has a name, an identifier, a hardware-address, 0 to m IP addresses etc.
An information model is not sufficient, as it does not determine how the information is mapped to the actual data. For instance, interface identifiers could be human readable, e.g., "exp0" which is a string, or just a number such as _15_. This general representation is described in a so-called data model, where the data elements, their syntax and their semantics are described. (TODO: needs better definition and citation)
