IPv4 Address Helper
Currently the assignment of IPv4 addresses to each and every interface is done manually. This becomes quite tedious and error-sensitive when the network size increases to a large scale. Here we developed a helper API through which the NeST users can automatically assign IPv4 addresses for emulation. To achieve the objective, we added 2 new classes, Network class and AddressHelper class. We also modified the Connect function of Interface class and topology_map file. Finally we added an example program to demonstrate the use case of IPv4 Address Helper API.
