The Power of Programmable Cloud Networking

For past few decades, our internetworks have been built and have operated in a decentralized manner, thus avoiding the pitfalls of a single point of failure. This is a design principle that comes from the original ARPANET, which was architected to survive the ultimate failure mode - a nuclear attack. Fundamental to these interconnected networks has been the use of open, standards-based protocols (TCP/IP and Ethernet) so that anyone can access these internetworks without requiring vendor-specific proprietary hardware or software. In this IP-based world, each network node runs its own control plane software, exchanging state with its neighbors to distribute information required to forward packets. With the migration to cloud networking, the ability of the network to respond to varying workload demands with on demand performance is key. In addition to dynamic workloads, the network demands higher availability and reliability at all levels. To meet these new requirements, the ability to achieve granular programmability of the products and software on which the network is built and operated is becoming a key mandate for next generation networking.
