Hi @TheMburu, I found you comment on my being navie and over confident a bit over the top, so I ran cross checks on your claim that Open Source developed OSPF. Turns out that it is the the usual story of Open Source, they have no original concepts or designs or research. In fact the entire basis of Open Source is based on work done in Universities or Inventors or Propreitary companies/organizations who release the concept or code for no financial gain. And Open Source seems to think it can claim these technologly advancements just by the fact that the original inventors/professors release the code for free public use. What I fail to understand is that when say for example Richard Stallman go to a place like CERN and give their views, how much will a scientist working on Nuclear fusion etc really make public their research findings public? The same place where the concept of internet was born, is the same place that is very propreitary in its operations. At network layer, you have a few well known vendors who created say Cisco and Juniper with proprietary mechanims that made their systems unique and popular. Juniper is based on some parts on FreeBSD, but this means nothing. FreeBSD cannot claim to have given birth to Juniper. It is the propreitary sectors that takes the concepts which have been made public or under trademarks that have been made public and does something unique with them, and this is where propreitary code developers shine. But now Open Source has a new enemy. Startups and Venture Funding, and the gains that Open Source made are being eroded slowly as more and more innovative minds are not releasing to free public use. They are going business. Take the example of Face Book. Proprietary and very successful. You may want to correct me again, and I'll still keep digging deeper for further knowledge. :-) Rgds.
