You are about to learn how a paradigm shift is occurring in enterprise networking, one that is driven by openness, modularity, and cloud-proven innovation. At the leading edge is Larch Networks, which provides a NOS based on SONiC, excelling in flexibility and practical reliability.
Imagine what it would be like to enter a world where you are not confined to vendor lock-in, and where state-of-the-art cloud networking smarts no longer belong to hyperscalers.
Your network becomes dynamic and alive, one prepared to handle AI workloads, edge expansion, and future challenges. Larch Networks does not simply provide you with a product; it offers you scalable, customizable, and reliable infrastructure.
In this article, we discuss in detail the reasons that make Larch Networks’ SONiC NOS ideal for enterprises.

1. Open‑Source, Cloud‑Proven Architecture
You’re going to love how SONiC begins on a battle-hardened foundation. It’s an open-source, Linux-based networking operating system designed by Microsoft to run Azure and now used as the Microsoft Global Cloud’s default switch OS.
That means that you aren’t dependent on proprietary software—you’re leveraging a state-of-the-art, production-hardened environment that hyperscalers use. As SONiC NOS is open source, you benefit from the openness and community-driven innovation.
It comes with next-generation protocols, such as BGP and RDMA, which have been deployed and tested in high-scale production environments.
By being part of a strong ecosystem—funded by industry giants and maintained under the Linux Foundation’s banner—you benefit from ongoing enhancements, interoperability, and security that come with peer-reviewed development.
In short, you’re building on a NOS that’s already delivering at cloud scale, and inviting innovation instead of constraints.
2. Separation of Hardware and Software via SAI
Larch Networks leverages the Switch Abstraction Interface (SAI) standard API to cleanly separate SONiC’s software plane from the underlying switch hardware, such as Marvell ASICs.
That is, you’re not tied to a particular silicon vendor. Rather, you can select or replace hardware beyond the NOS, allowing you to scale or change your infrastructure as your requirements change.
The genius of SAI is that it’s vendor-agnostic: you code forwarding components—ASICs, NPUs, or software switches—against a shared C-language API, without needing to deal with each vendor’s peculiarities. That lets you future-proof your network design, make life easier for ops, and minimize vendor lock-in.
With Larch Networks’ SONiC-based switches, you get the genuine article, a flexible and modular platform that accommodates your hardware choice.
3. Rich, Enterprise‑Grade Features & Modular Architecture
You stand to gain directly from a rich and exhaustive feature set embedded in Larch Networks’ SONiC-based switches. You have full L2/L3 switching capabilities, including VLAN trunking, static/dynamic LAG, and high-end routing protocols such as BGP, OSPF, and ECMP.
Additionally, you support data center-class virtualization with features like VXLAN, EVPN, and VRF.
Security is also bulletproof, with ACL (L2/L3/L4) support, storm control, and TACACS/RADIUS authentication, and PoE control and monitoring—from IEEE 802.3af/at PoE to budgeted available PoE negotiated through LLDP—providing you with accurate power control.
On the modular front, you’re gaining a system that’s built around a container‑based architecture. SONiC decouples core services into independent containers for improved fault isolation and serviceability, enabling fast or warm reboots, in‑service upgrades, and seamless scalability—ideal for agile, modern operations.
4. Versatile, Ready‑to‑Ship Hardware Portfolio
Larch Networks provides a diverse and plug-and-play hardware platform that scales to multiple networking use cases—spanning from Access and Campus to Data Center and Industrial sites.
You have an extensive selection of approximately 40–50 SKUs, including variations such as 48×1G + 4×10G, 32×400G, and 48×10G + 6×100G, among others. Most of these SKUs support PoE+, allowing them to seamlessly complement a variety of deployment scenarios.
That leaves you not having to wait for custom-ordered hardware—you can choose a model that suits your needs in port density, PoE support, or ruggedness for industrial environments.
If you have a data center with high-speed throughput needs or an industrial facility with rugged and PoE needs, you’ll have a specialized solution in Larch’s portfolio. You’re not just buying a switch—you’re choosing agility, speed to deployment, and fit-for-purpose design that adapts to your enterprise’s demands.
5. Enterprise‑Grade Reliability via “Hardened SONiC”
You get all the resilience of SONiC elevated to enterprise-grade robustness thanks to Larch Networks’ Hardened SONiC distribution.
This means you benefit from high availability features like Fast Reboot, Warm Reboot, and stateful process restarts—so your network stays operational even during upgrades or service interruptions.
You’re also gaining real-time insight through advanced telemetry and monitoring, with support for Prometheus, SNMP, and real-time analytics that keep your operations transparent and health-aware.
Built for cloud-scale networking, it handles up to 400 G capabilities and supports full L2/L3 protocol stacks like BGP, OSPF, MPLS, VXLAN, and more.
Additionally, your organization gains immediate credibility and R&D momentum, as Larch was named a Center of Excellence for Hardened SONiC by Xsight Labs, affirming its leadership and expertise in delivering secure, enterprise-ready SONiC solutions.
Bottomline
You’ve seen how Larch Networks’ SONiC-based solution offers an unbeatable blend of cloud‑proven open source, hardware flexibility via SAI, rich enterprise features, versatile hardware options, and rock‑solid hardened reliability.
As a member of the vibrant SONiC community—including expanding global collaboration through the Linux Foundation—you’re part of a movement powering the next-gen era of AI, data centers, and edge networking.
With Larch’s solutions, you’re not just deploying hardware—you’re embracing an agile, scalable, future‑ready NOS that grows alongside your evolving organizational needs.
