This book explains why the SDN movement happened. It was essentially about a change in control: the owners and operators of big networks took control of how their networks work, grabbing the keys to innovation from the equipment vendors. It started with data center companies because they couldn’t build big-enough scale-out networks using off-the-shelf networking equipment. So they bought switching chips and wrote the software themselves. Yes, it saved them money (often reducing the cost by a factor of five or more), but it was control they were after. They employed armies of software engineers to ignite a Cambrian explosion of new ideas in networking, making their networks more reliable, quicker to fix, and with better control over their traffic. Today, in 2021, all of the large data center companies build their own networking equipment: they download and modify open-source control software, or they write or commission software to control their networks. They have taken control. The ISPs and 5G operators are next. Within a decade, expect enterprise and campus networks to run on open-source control software, managed from the cloud. This is a good change, because only those who own and operate networks at scale know how to do it best.

Smeliansky R.L.Смелянский, Stepanov E.P.Степанов, Borisov A.V.Борисов, Semenikhin K.V.Семенихин The network powered by computing environment is the next step in the development of computing infrastructure after client-server, based on data processing centers. The following problem is under consideration: given a network where the vertices are computing resources (data processing centers, HPC, Edges).
