Aviz's blog argues that shifting packet-broker functions to software on commodity switches and using Data Processing Unit (DPU) offload can change Total Cost of Ownership (TCO) and ROI for deep network observability, and it outlines practical migration and cost-model approaches for enterprises.

Research overview

The post frames visibility equipment as a recurring expense historically renewed on multi-year cycles and includes the statement “The expensive but necessary plumbing we just renew every three years,” said the post.

Key findings

The blog reports modeled outcomes of SONiC-based packet brokers and DPU offload, citing roughly 30–40% Capital Expenditure (CAPEX) savings and 50% or greater Operational Expenditure (OpEx) savings, which it summarizes as overall TCO reductions near 40–60% in many deployments.

Technical breakdown

Aviz describes packet-broker functions running on white-box switches with merchant silicon and a service node that shifts packet processing tasks to a DPU, handling tasks such as GTP filtering, slicing, and subscriber-aware steering at line rate.

Operational impact

The post recommends phased adoption paths for organizations under multi-year contracts, including deploying new visibility domains or small production installs first, and reusing existing switching gear to align visibility operations with broader SONiC network stacks.

Leadership perspective

Aviz recommends building business cases with line-item comparisons of current NPB spend, tool licensing and consumption, and projected costs for SONiC-based hardware, support, and DPU-based offload, and it offers modeled case studies and customer references to support that analysis.

Enterprises evaluating deep observability can use the vendor's modeled metrics to quantify trade-offs between proprietary appliances and software-first, DPU-accelerated architectures; this Blog Signals brief is a fact-based summary of the vendor blog.
