eBay details 100G to 400G migration using SONiC at ONUG Dallas

Aviz plans to host a featured session at ONUG Dallas focused on eBay’s reported migration from 100G to 400G using open networking and SONiC, with outcomes described as a fourfold bandwidth increase plus improved cost efficiency and operational control.

Research Overview

The event materials describe a session built around how open, vendor-agnostic networking can support higher traffic demands while maintaining predictable NetOps operations. The program frames the discussion as practical guidance for scaling bandwidth and keeping operational processes consistent during modernization.

SONiC is positioned as the software layer used in eBay’s approach, with the materials describing increased hardware flexibility and longer-term operational control as goals for the transition.

Key Findings

The case study segment attributes a fourfold bandwidth boost to eBay’s move from 100G to 400G while also reporting improvements tied to cost efficiency. The materials also state that the approach aimed to strengthen operational predictability during the upgrade process.

Within the session overview, eBay’s stated challenge is described as scaling bandwidth as traffic increased without sacrificing cost efficiency or operational predictability.

Technical Breakdown

The materials describe the technical focus as migration from 100G to 400G implemented using open networking and SONiC. The session framing links the use of standardized networking to faster upgrades and stronger long-term operational control.

In addition to capacity changes, the program describes hardware flexibility as a factor, tying it to the operational control and NetOps consistency discussed for the SONiC-based approach.

Operational Impact

The event agenda outlines operational themes including improving hardware flexibility and maintaining predictable NetOps operations with open networking. The session overview emphasizes achieving bandwidth growth while keeping operational predictability as traffic demands rise.

For attendees, the materials describe learning outcomes around transitioning to 400G “with confidence,” improving cost efficiency while preserving control, and maintaining consistent NetOps operations at scale.

Blog Signals brief is a fact-based summary of the vendor blog, centered on Aviz’s ONUG Dallas session and eBay’s reported 100G to 400G migration using open networking and SONiC, with stated results covering bandwidth, cost efficiency, and operational control.
