Overview

OcNOS is a robust, programmable and innovative operating system, featuring a single software image that runs across the entire portfolio of Open Compute platforms from leading network device vendors. This guarantees consistent operations, workflow automation and high availability, while significantly reducing operational expenses.

OcNOS borrows heavily from the popular ZebOS line of products, which provides a rich feature density and robustness that has been built up over the years and validated in thousands of diverse customer networks. OcNOS provides industry standard CLI, supports all standard MIBs and other standard operation and management tools. Its integrated centralized management and provisioning layer allows for transaction-based configuration and device feature modelling. The management layer has support for Netconf, REST APIs besides custom CLI generation capability. This allows an OcNOS system to be configured, managed and controlled by Network Management System for scaled topologies and in multiple ways.

OcNOS is a modular, multi-tasking network operating system, with tight integration capabilities on commodity hardware. This design allows for scaled and performance critical deployments. The niche coupling with merchant silicon utilizes key hardware capabilities for better performance and feature set.

OcNOS is designed using several abstraction layers. The hardware abstraction layer, allows the OcNOS software to run over multiple control plane CPU and forwarding chipset hardware. The system calls are also well abstracted allowing to switch across operating systems if required. It has been integrated and verified with multiple commodity hardware, which again allows seamless portability across diverse network hardware.

OcNOS control plane software design is highly modular with multiple processes handling each individual key protocols. The processes are managed and contained by a process handler framework, which also monitors the processes, restarts and maintains event logging for them.

OcNOS can be customized, built and packaged with minimal software features, reducing CapEx and device footprint. The control plane features support for layer 2 switching, Carrier, Data Center Switching, MPLS/MPLS-TP, comprehensive support for multicast and unicast routing support.

OcNOS supports technologies required for bandwidth scaling at data centers and interconnects. The OcNOS centralized transaction based managed object modeling layer allows for multiple management interfaces. This, in turn, allows for a central service level provisioning and chaining across multiple devices. OcNOS infrastructure is SDN and NFV ready. The control plane and data plane has support for SDN support through OpenFlow. The SMI based C APIs provides end users the ability to write user defined functions to program the network control and data plane to provide custom programmable network operations.

OcNOS provides standards based redundancy protocols like VRRP, BFD, ring failure recovery protocols, MLAG, UDLD and graceful restart mechanisms. This protocol level redundancy provides guaranteed network level redundancy. For device level redundancy, OcNOS supports service availability frameworks based master-slave hot standby syncing. This feature is supported for several key protocols allowing device level redundancy in the absence of peer level network support. The modularity of OcNOS allows for individual process/protocol level upgrades and restarts without disturbing the running system for easy software upgrades. OcNOS will support ISSU for stateless upgrades. OcNOS has an in-built process heart beat monitoring and restart feature for process survivability in a 1 rack unit or multi-chassis format. This architecture helps in minimizing downtime in mission-critical network deployments.

The Service Provider mobile and wireline network of the future will not just need to provide exponentially higher bandwidth at lower operating costs but will also have to be capable of enabling new applications such as pervasive mobile broadband, IoT/sensor networks, autonomous vehicles and smart consumer wireless devices.

Mobile network operators are actively seeking cost-effective cell site gateway solutions to accommodate the mass rollout of 4G/5G services to meet this mobile traffic demands. Service Providers can take advantage of multivendor network and state of the art silicon to provide outstanding services to customers at low cost per bit. IP Infusion’s Provider Edge router enables operators to realize multi-vendor network at ease and improve service delivery at much lower cost.

IP Infusion’s OcNOS-SP-CSR is a complete carrier class, Cell Site Router (CSR) solution, aligning with TIP’s DCSG technical specification.  DCSG/CSR

Operators can use OcNOS-SP in various network  deployment scenarios. The following use cases are highly sought by leading Service Providers.

Web-scale networking requires new solutions to build hyperscale and cloud data centers equipped with a web-scale operations toolset. IP Infusion’s Network OS running on open networking switches combines the key principles of best-in-class hardware and software. Open Compute Network Operation System (OcNOS®) is an ideal platform to build both Layer-3 and Layer-2 Data Center fabric as it provides a rich set of control plane features, providing robust quality, ensuring lower costs and at the same time providing vendors the best of breed selection for hardware platforms.

OcNOS is redefining open networking, enabling the industry’s rapid transition to disaggregated networks for data center and internet exchange point use cases.
