1-400G Wire-speed Encryption

Deploying high performance, scalable bulk data encryption cost effectively is a major challenge for cloud data centers, enterprises and service providers. Arista 7280R3M, 7280R3AM and 7280R3AK Series platforms provide wire speed AES-256-GCM strong encryption for mixed speeds from 1G to 400G offering comprehensive choices for secure connectivity within facilities and over the wide area at an efficient cost point.

All 7280R3M, R3AM and R3AK systems provide standards-based IEEE 802.1AE MACsec for line-rate frame encryption and authentication. This ensures confidentiality as well as providing anti-replay protection and therefore confidence in the integrity of encrypted traffic.

Arista TunnelSec provides advanced encryption and is available on 7280R3AM and R3AK systems. TunnelSec is a standards-based approach to increasing the performance and utility of strong encryption for modern networks. TunnelSec adds support for IPsec and VXLANsec in addition to MACsec. IPsec and VXLANsec both enable the construction of encrypted IP tunnels that traverse multiple unencrypted hops between endpoints. IPsec operates router-to-router, while VXLANsec provides VTEP level integration for simple deployment of encrypted overlays. Both IPsec and VXLANsec provide a solution to line-rate strong encryption across third party infrastructure for WAN or DCI deployments.

MACsec, IPsec and VXLANsec solutions leverage AES-256-GCM for strong bulk encryption and operate at full line rate. The flexibility provided by offering encryption at different network layers enables a broad range of deployments and removes the need for additional encryption devices while providing orders of magnitude improvements in latency and throughput when compared to traditional appliances.

Key Benefits

  • Provides high performance L2 and L3 features with wire speed MACsec and IPsec encryption in compact form factors.
  • Multi-speed support for 10/25/40/50/100/200 and 400G
  • Eliminates the need for external encryption devices.
  • Provide secure communication for a wide range of applications from large scale leaf and spine networks to data center interconnect.
