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.

Common Platform, Multiple Use Cases

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.

Optical Transport Networks –  OcNOS OTN enables the choice of best-in-class transponders, open line systems and management interfaces with open APIs and addresses the following use cases:


IP Infusion’s OcNOS-OLT is a truly disaggregated Passive Optical Networks (PON) software solution which supports multi-vendor OLT and ONU bare metal hardware platforms. Customers will have the freedom to pick the best-of-breed OLT and ONU which best-fit their needs.

Similar to other segments of the access network, the disaggregation is transforming the OLT segment and brings many benefits to the service providers:

OcNOS-OLT has implemented simple-to-use configuration commands that users can easily provision the devices, quickly launch and modify subscriber services without a steep learning curve reducing the OPEX cost.

Distributed Disaggregated Chassis (DDC) for Residential and Enterprise Services

The OcNOS-OLT supports Distributed Disaggregated Chassis architecture, a disruptive innovation that transforms the traditional chassis into separated components for higher scalability and better flexibility. In the PON case, the traditional modular chassis that composes of PON MAC line cards and switching fabric cards, now can be broken down to separated OLT pizza-boxes connected to a Top-of-Rack (TOR) switch.  OcNOS-OLT will control the OLT pizza-boxes while the TOR switch can provide L3/MPLS/VPN functionalities. The central office deployment for residential and enterprise services is a leading use case for service providers.

Expanding Capacity of Ethernet Switches Using Micro-OLTs

Recent advanced hardware technologies enable the innovation of the micro-OLTs in SFP+ form factor which can be plugged into an Ethernet switch and unleash the PON functionalities and benefits to an existing Ethernet Switch with a relatively small and incremental CAPEX investment. This is particularly beneficial for the customers who already deployed Ethernet switches indoor or outdoor and would like to extend the service coverage with a low budget using passive optical networking.

Expanding Capacity of uCPE Using Micro-ONUs

For enterprise subscribers, Universal Customer Premises Equipment (uCPE) provides a platform to host different services at customer edge. Installing a Micro-ONUs in SFP+ form-factor into the uCPE’s WAN port allows the uCPE to connect to the PON Optical Distribution Network (ODN) eliminating the need of an external ONU box.
