Arista Networks, Inc. · 2026-08-04 · Importance 31 · Surprise 42

Arista highlighted Smart System Upgrade, or SSU, which allows switch software upgrades without disruption or loss of accelerator operating time. Multipath Reliable Connection enables a single XPU-to-XPU flow to use multiple paths, reducing performance losses from fabric hash collisions. Segment Routing IPv6 combines explicit path selection with real-time congestion signaling across both scale-out fabrics and long-distance scale-across networks.

Key facts

• Arista's Smart System Upgrade (SSU) enables upgrading switch software without any disruption.
• Arista uses MRC (Multipath Reliable Connection) to spray a single flow across many paths and have receivers reassemble out-of-order data to eliminate fabric hash collision performance hits.
• Arista uses SRv6 with senders tagging each packet with a stack of SRv6 segment IDs to dictate exact paths and dynamically shift packets away from hotspots using real-time congestion signaling.
• Arista supports SRv6 intelligence all the way from the scale-out fabric to the long-distance scale-across routing because EOS provides a single unified operating system.
