Software-defined networking startup Arrcus Inc. said today that it has raised $30 million in a new funding round that brings its total capital to raised to $49 million.

The oversubscribed Series B round was led by Lightspeed Venture Partners, with participation from existing investors General Catalyst and Clear Ventures.

Arrcus emerged from stealth mode last year touting a network operating system called ArcOS that runs on white-box switches and routers in physical, virtual and cloud environments. ArcOS is designed for data center operators, content delivery networks and telecommunications carriers. It enables open networking that addresses data center workloads, internet peering (the interconnection of separate networks), resilient routing to the host and massively scalable clusters in physical or software container form.

ArcOS is comprised of a set of software modules that provide various management capabilities for coordinating network operations. These include a “hyper-performance resilient control plane” and application programming interfaces that enable companies to create automation workflows. ArcOS also features a telemetry tool that can collect detailed information about network activity for monitoring purposes.

The modules that make up ArcOS are based on a microservices architecture similar to that of modern, container-based cloud applications. The main advantage is that users can restart a component for maintenance purposes without having to take the entire deployment offline, which reduces downtime.

Arrcus founder and Chief Executive Officer Devesh Garg (pictured, right, with General Catalyst Managing Director Steve Herrod) last year appeared on theCUBE, SiliconANGLE Media’s mobile livestreaming studio, arguing that ArcOS was more flexible and scalable than traditional networking setups:

Arrcus said the new funds will be used to expand its operations to support its growing customer base and scale up its strategic partnerships and production. Garg said in a statement that Lightspeed and Guru will help strengthen the company’s infrastructure expertise and operational scale. “Business providers and enterprises alike want to move away from closed, proprietary, vertically integrated systems and prefer the freedom of choice,” he said.
