What does "RPF" stand for?

"RPF" is an acronym with multiple meanings, two primary ones being Reverse Path Forwarding and the Rwandan Patriotic Front. Other meanings include Rehabilitation Project Force, Railway Protection Force, Renal Plasma Flow, Real Person Fiction, Relative Performance Factor and more.

The Rwandan Patriotic Front is famous for ending the 1994 Rwandan Genocide. The operation began in April 1994, and opposition was minimal except around Kigali. However, in an effort to prevent tens of thousands of deaths, they killed thousands in the process, ending the conquest in July 1994. Most forces killed by the RPF were Hutu, but the RPF claimed a nationalistic ideology without ethnic distinctions.
