The Many Facets of Software-Defined Switching

In recent times many Software Defined Networking (SDN) advocates are seeking to establish a new paradigm of networking that better optimizes for applications in place of establishing simple connectivity. This software may be embedded in management controllers or protocols depending on the application. What is clear is developing and deploying modern software for next generation switching and routing is paramount. More importantly, the software has to be designed optimally for the applications, resilience and scale of cloud networking instead of legacy enterprise environments. It must coordinate its orchestration protocols in a highly distributed fashion, rather than create more coordination choke points between switches as legacy OS’s often do.

Upon recognizing the weakness of legacy switches and old monolithic switch operating system software, you end up discovering that we do not need to re-invent three decades of control plane networking again. Instead, the right answer is to build a highly distributed publish-subscribe model with standards-based open protocols, such as Arista’s Extensible OS (EOS). Like our 1500 customers, I am convinced that Arista EOS is the only advanced networking software designed from the ground up to properly tackle the operational problems of modern networking. It encompasses the powerful combination of openness, a modern control plane and programmability while preserving the distributed model that has brought us so far in internetworking.

Arista recognizes that there exists a set of customers for whom application performance and latency is critical. Utilizing the programmability and extensibility of EOS, Arista built the 7124FX, the industry’s first Application Switch. This industry first enables the integration of specific components of the application into the network, dramatically accelerating application performance by facilitating programmatic control of the data plane in real time. This product represents the first phase of Arista’s development of software-defined and controlled application acceleration switches.
