Arrcus
Arrcus is a networking software company that develops a Linux-based, programmable network Operating System (OS) and related platforms for routing, switching, and multi-cloud connectivity in carrier, cloud, and enterprise environments.
- Software-based routing and switching platforms for service providers, cloud operators, and enterprises (network infrastructure).
- Disaggregated network OS for white-box and merchant-silicon-based hardware deployments (network OS).
- Multi-cloud and hybrid cloud connectivity solutions for data centers, edge, and Wide Area Network (WAN) environments (cloud networking).
- 5G transport and edge networking solutions for mobile and telecom operators (telecom networking).
- Automation, telemetry, and programmability capabilities through standard APIs and modern data models (network automation and observability).
More About Arrcus
Arrcus focuses on software-centric networking, delivering a disaggregated network OS that runs on merchant silicon and a range of white-box and Original Equipment Manufacturer (OEM) hardware platforms. Its offerings are designed for use in carrier networks, cloud provider environments, large-scale data centers, and enterprise WAN and edge architectures. By decoupling the network OS from proprietary hardware, Arrcus targets organizations that want to standardize on common silicon platforms while retaining flexibility in how they design and scale routing and switching infrastructure.
The Arrcus network OS (network OS) is positioned as a foundational layer for high-performance routing and switching (network infrastructure) across core, aggregation, and access layers. It is built on a Linux foundation and supports hardware forwarding pipelines from multiple merchant silicon vendors. This enables deployments such as spine-leaf data center fabrics, peering and core routers for service providers, broadband network gateways, and enterprise edge routing platforms. The software is typically orchestrated through APIs and integrates with standard network automation frameworks.
In cloud and data center environments, Arrcus provides solutions for multi-cloud and hybrid cloud networking (cloud networking). These offerings are used to connect workloads across on-premises (on-prem) data centers, public cloud regions, and edge locations. The software supports standard routing protocols such as Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF), as well as EVPN and Virtual Extensible LAN (VXLAN) for Network Virtualization (NV) and overlay fabrics. This positions Arrcus within enterprise categories that include data center networking, cloud interconnect, and SDN-based fabric control, while still relying on industry-standard protocols rather than proprietary overlay schemes.
For telecom and mobile operators, Arrcus supplies 5G transport and edge networking capabilities (telecom networking). These solutions are aimed at segment routing, converged IP/MPLS networks, and edge data center connectivity for 5G core and Radio Access Network (RAN) architectures. The platform leverages standard protocols and features used in carrier environments, such as Multiprotocol Label Switching (MPLS), Segment Routing, EVPN, and advanced Traffic Engineering (TE). This allows operators to deploy the same software stack across core, aggregation, and edge locations while aligning with existing operational practices.
Arrcus also emphasizes programmability, observability, and automation (network automation and observability). The platform exposes standard APIs, supports model-driven configuration using YANG data models, and integrates with orchestration and telemetry systems. This enables integration with Continuous Integration and Continuous Deployment (CI/CD) pipelines for network changes, streaming telemetry for real-time monitoring, and closed-loop automation workflows. From a directory taxonomy perspective, Arrcus aligns to network operating systems, data center and cloud networking, WAN and edge routing, and service provider/5G transport infrastructure categories.
