          NRL SMF Source Code Distribution

The NRL Simplified Multicast Forwarding (nrlsmf) project includes software for a user-space forwarding engine. This software is was developed by the Naval Research Laboratory (NRL) PROTocol Engineering Advanced Networking (PROTEAN) Research Group. The goal of this effort is to provide an implementation of experimental techniques for robust, efficient distribution of broadcast or multicast packets in dynamic, wireless networks such as Mobile Ad-hoc Networks (MANETs).

The nrlsmf application can be run as a stand-alone application capable of providing "classic" flooding of broadcast and multicast traffic for a specified network interface or can be used in conjunction with a controlling program to perform more sophisticated multicast forwarding. An interprocess communication "remote control" interface is provided so that a compatible program (e.g. nrlolsr) may issue real-time commands to nrlsmf to control the multicast forwarding process. Both IPv4 and IPv6 operation are supported. Versions of nrlsmf can be built for the following operating systems: Linux, MacOS, BSD, Win32, and WinCE.

Build Instructions

Requires Protolib: https://www.nrl.navy.mil/itd/ncs/products/protolib https://github.com/USNavalResearchLaboratory/protolib

For Unix platforms, the "nrlsmf/makefiles" directory in the source tree contains Makefiles for different platforms. Type:

make Makefile. nrlsmf

to build the nrlsmf binary executable.

For Win32 platforms, a distribution of "winpcap" is required to build the nrlsmf.exe executable. A Visual C++ solution (nrlsmf.sln) and project files are provided in the "makefiles/win32" directory for building nrlsmf.exe.

For WinCE (a.k.a. PocketPC) platforms, the "RawEther" library is required. The Rawether development kit is a commercial product available from http://www.rawether.net. (Note we are able to provide a binary distribution of nrlsmf.exe for WinCE platforms including the required Rawether libraries). A workspace (nrlsmf.vcw) and project files are provided for the Embedded Visual C++ compiler.

See the "nrlsmf.html" or "nrlsmf.pdf" file for further instructions.
