Marvell has been actively involved with SONiC since its beginning, with many SONiC switches powered by Marvell® ASICs at hyperscalers deployed worldwide. One of Marvell's goal has been to enhance SONiC to address common issues and optimize its performance for large-scale deployments.
The Challenge
Many hackathon projects have focused on improving the monitoring, troubleshooting, debuggability, and testing of SONiC. However, we believe one of the core roles of a network operating system (NOS) is to optimize the use of the hardware data plane (i.e., the NPUs and networking ASICs). As workloads become increasingly more demanding, it becomes crucial to maximize the efficiency of the data plane. Commercial black-box NOS are tailored to specific NPUs/ASICs to achieve optimal performance. SONiC, however, supports a diverse range of NPUs/ASICs, presenting a unique challenge.
We at Marvell have been contributing features to SONiC to ensure optimal use of the underlying networking ASIC resources. Over time, we’ve recognized the need to provide operators with flexibility in utilizing ASIC resources while reducing the platform-specific complexity gradually being introduced into SONiC’s core component, the Orchagent. This approach will help SONiC operators to maintain consistent device configurations even when using devices from different platform vendors.
BYOC
During the Hackathon, we developed a framework called “BYOC: Bring Your Own Configuration,” allowing networking ASIC vendors to expose their hardware capabilities in a file describing intent. A new agent transforms the user’s configuration into an optimal SONiC configuration based on the capabilities file. This approach allows ASIC vendors to ensure that user configurations are converted to optimal ASIC configurations. It also allows SONiC operators to fine-tune the hardware resources consumed based on the deployment needs. It further helps in optimally migrating configurations from vendor NOS to SONiC based on the SONiC platform’s capability.

Disaggregation is the future
Disaggregation—the decoupling of hardware and software—is arguably the future of networking. Disaggregation lets customers select best-of-breed hardware and software, enabling rapid innovation by separating the hardware and software development paths.
Disaggregation started with server virtualization and is being adapted to storage and networking technology. In networking, disaggregation promises that any networking operating system (NOS) can be integrated with any switch silicon. Open source-standards like ONIE allow a networking switch to load and install any NOS during the boot process.
SONiC: the Linux of networking OS
Software for Open Networking in Cloud (SONiC) has been gaining momentum as the preferred open-source cloud-scale network operating system (NOS).
In fact, Gartner predicts that by 2025, 40% of organizations that operate large data center networks (greater than 200 switches) will run SONiC in a production environment.[i] According to Gartner, due to readily expanding customer interest and a commercial ecosystem, there is a strong possibility SONiC will become analogous to Linux for networking operating systems in next three to six years.
