About the Arista 7280R3 Series 100/400G Edge Routing Switch

The Arista 7280R3 Series is a high-performance, deep-buffer routing platform engineered for data center interconnect (DCI) and WAN edge deployments. The 7280R3-24D-F model delivers 100/400G port density with advanced buffer architecture designed to absorb microsecond-scale traffic bursts and maintain consistent throughput in congestion scenarios. Built on Arista's EOS operating system, the platform supports both traditional routing and cloud-native networking paradigms with integrated telemetry and traffic engineering capabilities.

The 24-port design optimizes cost and power efficiency for edge and DCI use cases while maintaining wire-rate performance across all forwarding paths. Deep buffering enables effective congestion management in high-ratio oversubscribed networks and simplifies QoS provisioning. Hardware-based ECMP, multicast, and segment routing (SR) support enable sophisticated traffic steering without controller dependency.

The 7280R3 platform remains production-proven across major hyperscale, carrier, and enterprise deployments since its Q1 2024 release, delivering operationally simple, standards-compliant edge routing at scale.

Ideal for

  • Data center interconnect (DCI) backbone routing with sub-50ms latency requirements across regional sites
  • WAN edge aggregation for multi-cloud traffic steering and SD-WAN appliance integration
  • Content delivery network (CDN) peering and internet exchange point (IXP) core routing
  • High-frequency trading and financial services network edge with microsecond-sensitive latency profiles
  • Large-scale video streaming and media delivery with real-time congestion absorption
  • Carrier-grade IP backbone consolidation with deep buffer protection against tail-latency events
