Aviz Networks details SONiC as an open-source network operating system alternative

Traditional network Operating System (OS) (NOS) providers faced challenges fulfilling open networking goals, often offering only partial disaggregation and proprietary software that led to vendor lock-in. This has created operational and strategic issues for enterprise IT leaders seeking flexible and sustainable networking solutions.

Research overview

Early Software Defined Networking (SDN) companies frequently combined partial disaggregation with proprietary hardware dependence, limiting scalability and openness. These firms were subject to acquisitions or shutdowns, disrupting user support and prompting customers to explore alternative solutions.

Key findings

SONiC (Software for Open Networking in the Cloud), initially developed by Microsoft and now governed by the Linux Foundation and Open Compute Project, offers an open-source Network Optimization Suite (NOS) independent of proprietary vendor constraints. It supports full disaggregation, vendor neutrality, and ongoing development, distinguishing it from traditional NOS vendors that face acquisition or end-of-life risk.

SONiC is utilized by major cloud providers such as Azure, Google, and Meta, and receives backing from hardware vendors including Cisco. It delivers attributes like scalability, high availability, and security without the vendor lock-in common in partial disaggregation models.

Technical breakdown

SONiC undergoes automated one-click validation processes assessing reliability and performance across various scenarios, with certifications supporting its application readiness. Its architecture aligns with DevOps practices by providing standardized APIs, modular components, and automation capabilities that support Infrastructure-as-Code (IaC) and Virtual Extensible LAN (VXLAN) overlays, facilitating faster and less error-prone deployments.

Operational impact

The flexibility and broad Application-Specific Integrated Circuit (ASIC) compatibility of SONiC make it suitable for deployment in edge environments, retail branches, and telecommunications access networks. When combined with Aviz Networks’ ONES 2.0 solution, organizations can achieve enhanced observability, automation, and compliance, supporting operational reliability.

Product update

Aviz Networks offers vendor-neutral onboarding tools, support services, deep network observability, and orchestration through ONES, which assists enterprises in transitioning to an AI-ready, open networking architecture based on SONiC.

With legacy NOS platforms being phased out and market shifts underway, migrating to SONiC presents opportunities for reduced Total Cost of Ownership (TCO), improved vendor flexibility, and access to a community-driven open-source ecosystem.
