Integration of HFTB into OSPF:

Note: Our work is based on the OSPF software written by John T. Moy. Our algorithm proposes a few changes to the original implementation. Due to copyrights and proprietary restrictions, we are unable to provide the entire code. For testing and academic purposes, we can send you a soft copy of our code. Please contact us at korkmaz@cs.utsa.edu. Given here are a few significant modifications to John’s implementation.

The data structure to maintain the parent-children table at each node is implemented by defining a class named PCTable. The source code for this is placed in pctable.h and pctable.C.

In addition, changes are made to the following files in the OSPF implementation (by John T. Moy).

arch.h

dbage.C

ospf.h

ospf.C

rtrlsa.C

spfack.C

spfifc.C

spflood.C

spfpkt.h

Here are the configuration files describing the modified ANSNET topologies that are used in our simulations:
