In my role as a Customer Solutions Engineer (affectionately known as CSE) at Cumulus Networks, I am on the frontlines discussing customer requirements, use cases and networking architectures. A frequent question that customers ask me is “what can an open network operating system (OS) do for me?”
Most customers have lived in the world of black boxes where the OS and hardware are vertically integrated and your vendor keeps you in a sandbox that controls what you can and cannot do.

This summer we blogged about a series of BGP hijacks where an attacker cleverly misused the Bitcoin stratum protocol. By Continue reading
