- New content delivery routing architectures mandate support for software-driven traffic steering for optimal content delivery and increased visibility at scale. Customers are moving away from legacy router software in favor of lean, modern operating systems with advanced programmability foundations.
- Internet eXchange (IX) networks provide interconnect fabric between consumers and providers of services at critical junction points of the Internet. The IX operator is moving from traditional Layer 2 fabrics to a common Layer 3 service architecture with rapid provisioning of new interconnect services.
- Consumer edge networks in telco and cable providers require an architecture that delivers cloud-like service agility, replacing legacy multi-service edge routing with scale-out cloud routing. These new NFV architectures require enhanced software control and automation to bring cloud networking to the consumer edge.
Building Flagship Routing with Arista EOSWith the latest Arista EOS 4.20 release, Arista supports the following capabilities for the transition to cloud-grade routing:
- Scale-out: Modern routing software, leveraging a state-based architecture programmable at all layers. Optimized for a common spine/leaf design in and outside the datacenter, with enhanced load balancing, best-in-class convergence for large-scale ECMP (Equal Cost Multipath). Network-wide visibility with BMP (BGP Monitoring Protocol) and real-time state streaming.
- Simplify: A lean operating system, with a single software train running IP+Ethernet fabrics utilizing standard routing protocols (BGP, EVPN, Segment Routing).
- Software-driven Control: Automating network operations and traffic engineering, utilizing programmability tools (EOS SDK), open APIs (OpenConfig/YANG, NETCONF), CloudVision for turnkey provisioning and telemetry, and cEOS/vEOS for large-scale network simulation and certification.
