Distance Vector Routing Protocol (DVRP) Integration for ns3

As IPv4 proactive table driven routing protocol, the DVRP is implemented to the ns-3. This routing protocol ebables a good platform for testing and experimenting with different network typologies.

The DVRP is a IPv4 unicast only routing protocol, which is developed based on the Bellman-Ford algorithm. In particular, DVRP is developed based on RIPv2 (RFCs : rfc: 2453) and thus, DVRP supports some additional features that are not defined in both RPIv2 and RIPng. Among those additional features, use sequence numbering for route updates, and maintain a neighbor table for fast reactions for topology changes are major.

The protocol is very simple, and it is normally suitable for flat, medium scale network typologies.

USAGE

---

Building the DVRP

Download the DVRP patch file the ns3 executable directory (i.e., /ns-3.21). Then patch the ns3 using::

$ patch -p1 < dvrp.patch

Upon successful patch you can see the 'dvrp' folder is created under::

$ cd src/ $ ls

Once the DVRP has been created successfully, change into the ns3 executable directory and configure ns3 with DVRP integration support::

$ cd .. $ ./waf configure --enable-examples --enable-tests $ ./waf build

Hint: If the DVRP module is installed and build successfully, you can execute the DVRP example as follow::

$ ./waf --run "dvrp-example --MTable"

and you an observe the routing table of the node3.
