With its design to take advantage of Open Compute Project enabled commodity or bare-metal hardware, OcNOS reduces Capex and Opex for service providers.
OcNOS has an integrated centralized management and provisioning ZebM-based layer, which allows for transaction-based configuration. This provides the key services required for Model-based device Configuration and Orchestration. The management layer exposes NETCONF, REST APIs besides custom CLI generation capability. Combination of these services allows an OcNOS system to be configured, managed, and controlled in several ways by Network Management Systems for scaled topologies. OcNOS includes the industry-leading implementation of the NETCONF protocol and YANG modeling language to ensure that all changes are made consistently across all network devices. With OcNOS, all devices within the service provider environment should be capable of participating in network-wide transactions. This significantly reduces OPEX for the device.
OcNOS is the industry’s most advanced network operating system for Open Compute Platforms based networking devices.
OcNOS has been created to address the needs of public/private/hybrid cloud networks. OcNOS enables new applications for Software Defined Networks (SDN) and Network Functions Virtualization (NFV) requirements.
OcNOS is built around a proven set of modular framework components for control, data plane integration, a transactional management plane, plus middleware to support high availability for nonstop operations in mission critical networks.
OcNOS is a modular, multi-tasking Linux-based network operating system, with tight integration capabilities on commodity open compute network hardware.
OcNOS borrows heavily from the popular ZebOS® line of products having carrier grade, rich feature density and robustness built up over 15+ years or development; and is deployed with over 300+ OEMs. OcNOS provides industry standard CLI, NETCONF, support all standard MIBs and other standard operation & management tools.
Key Features and Capabilities
Common software for multiple deployments and hardware: OcNOS abstraction layers, allow the software to seamlessly run over commodity hardware.
Traffic Monitoring based on sFlow: Can be easily integrated with Monitoring systems such as Ganglia, Collectd etc.
Rich Ethernet switching services: The solution supports the complete feature set required to run it as a pure Layer2 or Layer2-3 switch. Key features are support for Rapid Spanning Tree Protocol(RSTP), Multiple Spanning Tree Protocol(MSTP) IEEE 802.1w & 802.1s, RPVST, QinQ, IEEE 802.3ad Link Aggregation, Multi-Chassis Link Aggregation, EVB and DCB support.
Key Datacenter features: OcNOS supports multiple standards based multi-path Ethernet technologies for the datacenter. These are TRILL, SPB, and Multi-chassis Link Aggregation Group. Apart from them, it also supports Data Center Bridging (DCB), QCN, ETS, and PFC for true unified Ethernet backplane. For Layer-3 based data center deployments, OcNOS has BGP, OSPF support with a very large ECMP fan out.
