Just ten years ago, it would have been difficult to imagine the entire networking industry being disrupted by open source. While as an industry we benefited from open source at the operating system level, including in embedded networking devices, and at the software component level, we took for granted that the core routers, switches and L4-7 appliances in our data centers, campuses and WAN would be proprietary boxes that came from networking vendors dueling for dominance in a closed ecosystem.
Today, we see quite a different landscape, with open source gaining sufficient prominence that we see open source projects powering networks at large telcos like AT&T, Telefonica, China Mobile, NTT, to name just a few. And open-source software and hardware powers a good part of the network infrastructure at the world’s largest web properties and cloud service providers, such as LinkedIn, FaceBook, Google, Microsoft, and Amazon.
As well, large system integrators worldwide have embraced open source and have built new practices with large teams familiar with the most popular open-source projects in networking, ready to help enterprises and service providers benefit from the hundreds of millions of lines of code already developed and ready to be used.
