PINS Project Extends Leading Open Source Network OS with P4 Programmability

MENLO PARK, Calif. FEB 17, 2022 – The Open Networking Foundation (ONF) today announced the upstream contribution of its collaboratively developed P4 Integrated Network Stack (PINS) into Software for Open Networking in the Cloud (SONiC), the leading open source network operating system for data centers. PINS extends SONiC with an Software-Defined Networking (SDN) interface and P4 programmable pipeline, providing network developers with a standardized and fully documented interface that simplifies and accelerates network programming, validation, testing, and analysis.

SONiC, a switch operating system for data center scenarios, uses embedded control plane protocols (e.g. BGP and OSPF) to build disaggregated networking fabrics. SDN, on the other hand, espouses building centrally controlled fabrics with a common controller that has end-to-end visibility of the entire topology. Until now, operators have had to choose one over the other, either a disaggregated solution or an SDN architecture. Integrating PINS into SONiC now makes it possible to have the best of both worlds.

The ONF, along with community leads Microsoft, Google and Intel, created PINS to marry SDN intelligence into SONiC.  The broader community, including Alibaba, Arista, Broadcom, Cisco, Innovium, and NVIDIA are working with ONF to incubate the project and extend PINS with additional features and capabilities. 

PINS Highlights:

  • Supports Hybrid Control Planes: PINS gives network operators a choice of network control planes, and which parts run locally or remotely, and even allows the control planes to be mixed with certain functions running locally (like traditional routing protocols such as BGP) and other control operations (like traffic engineering) being centrally orchestrated.
  • Opt-In Path Towards SDN: P4Runtime and SONiC have been combined such that SONiC will continue to work the way it does today, while enabling users to migrate towards an SDN solution without initially requiring an SDN controller. Using P4Runtime, users can control essential networking features, including L3 routing, Weighted-Cost Multipath (WCMP) routing, and ACLs (with more capabilities planned for future releases).
  • Familiar Interfaces: PINS uses P4 to model the SAI pipeline used by SONiC to model the data plane pipeline. PINS also provides a P4Runtime interface that exposes this pipeline to local and remote control planes over a fast and secure gRPC connection.

The source code for the first set of PINS features has already been merged to the upstream SONiC repositories and is part of the 202111 release; this includes a new P4Runtime interface and P4 control of the routing, WCMP, and ACL tables. PINS also includes extensive design documents available on Github, open and accessible to anyone.

“SONiC OS has gained rapid momentum in the data center and cloud market within just five years as a standard and widely deployed open source network operating system. Today, ONF is excited to have helped bring PINS to SONiC, offering the option to leverage SDN capabilities and P4 programmability within networks based on traditional distributed control planes like BGP.  ONF has been an unabashed champion for SDN, and we are thrilled that PINS now makes SDN accessible to the full community of operators leveraging SONiC.”
Guru Parulkar, Executive Director, Open Networking Foundation

“The SONiC community is thrilled to work with PINS to give network architects maximum freedom in designing their networks. Making P4 a first-class citizen on SONiC switches enables architects to model new data-planes. Network operators have the choice of over 100 switches that run SONiC and the flexibility to write code that runs on the switches or on controllers that communicate with the network device via PINS.”
Dave Maltz, Technical Fellow and Corporate VP, Azure Networking, Microsoft

“Google has been using SDN in our data centers and WAN for over a decade, and we’re very excited to have helped bring SDN capabilities to SONiC. We’ve seen the benefits that centralized control can bring for tasks like traffic engineering, hitless route sequencing, and fault detection. We want a broader set of constituents to be able to realize similar benefits on a common switch platform.”
Mythil Raman, Director, Google Cloud Platform

“Intel has collaborated with data center operators to drive production deployments of both SONiC and SDN with our proven, fully P4-programmable networking silicon, such as Intel Tofino Intelligent Fabric Processors and Intel IPUs. Combining the best of SONiC with the best of P4 programmability allows network operators to innovate without disruption to their existing networks.”
Ed Doe, VP and GM, Switch & Fabric Group, Intel

ONF is excited to be exhibiting at Mobile World Congress this year along with our member sponsors Deutsche Telekom, Intel, Netsia and Radisys. Please stop by the ONF pavilion (Hall 1 Stand 1F66) and check out the ground-breaking open source demos we will be featuring:

 

Aether is the first open source 5G Connected Edge platform for enabling enterprise digital transformation. It provides mobile connectivity and edge cloud services for distributed enterprise networks using licensed, unlicensed and lightly-licensed (CBRS) spectrum. This live demonstration of Aether showcases all the fundamental building blocks of Aether offered as a managed service. 

The demonstration features an enterprise portal for configuring dedicated network slices and QoS for mission critical applications. Connected devices such as mobile phones, cameras and other IoT devices associated with different slices can be flexibly assigned to different edge applications thereby extending the slicing concept to the edge servers. Network administrators can view network slice health, RAN status and connected device information via the portal.  Intelligent edge applications leveraging AI/ML platforms like OpenVINO can reach back into the Aether network to change network parameters to offer superior services by leveraging Aether’s rich APIs.

Sponsors

The SD-RAN project is an open source implementation of the O-RAN architecture, and includes a near-real-time RIC (nRT-RIC) and a set of exemplar xApps for controlling the RAN. Recently, ONF and Deutsche Telekom deployed the first fully disaggregated outdoor SD-RAN trial in Berlin, interconnecting components from over 8 vendors using the SD-RAN RIC. The trial is also operationalized leveraging ONF’s Aether platform and SD-Core dual-mode 5G/4G mobile core. 

Aether hosts the Radisys containerized CU while the Intel® Smart Edge Open software toolkit hosts the Radisys DU to enable cloud-native deployment of the RAN workload with optimization on the 3rd Gen Intel® Xeon® Scalable processor and Intel® vRAN Dedicated Accelerator ACC100. The Radisys CU and DU are integrated with ONF’s nRT-RIC, xApps and SD-Core 5G core. Aether’s components are interconnected with a P4-programmable Intel® Tofino™ Intelligent Fabric Processor based switch to become interconnected with a P4-programmable Intel® Tofino™ Intelligent Fabric-based switch.

Stop by the SD-RAN community kiosk to learn more about the disaggregated use of RU and CU/DU from different vendors, as well as three RIC use-cases: Mobility Load Balancing (MLB), PCI-conflict resolution and KPI monitoring.

Mobile network automation presents a significant opportunity for the telecom industry to further reduce cost and improve service quality. With thousands of network elements, the radio access network is a prime area of focus for automation innovation by mobile operators today.

An essential component of modern mobile network deployments, microwave links provide a cost efficient, rapid deployment option to connect radio units that can be sited for optimal coverage and performance. As 5G networks continue to grow, this flexibility becomes more important and the volume and complexity of mobile backhaul continues to increase, placing ever more value on mobile network automation.

Achieving automation of microwave transmission requires a standardized management interface. The information and data models developed by the ONF OTCC 5G-xHaul community resulted in a reference implementation integrating 40,000 microwave devices into an Open Daylight Controller, operating in the Telefónica production network.

All microwave devices in Telefónica’s mobile backhaul network are now accessible via a single harmonised API (ONF TR-532), which is the key enabler of a microservices architecture.

ONF is pleased to announce the release of updated Reference Implementation Agreements for TAPI v2.1.3, version 1.1 of TR-547 and TR-548. These 1.1 versions update and enhance the 1.0 version.  The Reference Implementation Agreements are the result of joint collaboration between optical network providers and operators within the OTCC Project at ONF. The goal of this effort is to create a standard reference specification for the implementation of TAPI 2.1.3 based optical network management, by leveraging operator experiences with testing and deployment. TAPI 2.1.3 is a production-grade API that has been deployed in real networks and interoperability tested by OIF.  The Reference Implementation Agreements present a comprehensive guide for the development and implementation of different use cases ranging from optical network discovery, service provisioning, hardware inventory and simple fault management.

The target audience for this document is both network providers deploying TAPI as a northbound interface for their SDN controller systems, and client layer applications and Operations Support Systems (OSS) consuming TAPI as a southbound API. 

TR-547 v1.1

TR-547 v1.1 is the result of a thorough, line-by-line review of version 1.0, resulting in better and more detailed explanations, enhanced document structure and overall consistency and readability.  It incorporates feedback from Interop testing of TAPI 2.1.3, such as the need to supplement RESTCONF related standards specifications to facilitate interoperability.

Support for new operator uses cases has also been added, e.g.

  • Multi-domain OTN interdomain links discovery.
  • Asymmetric DSR Service Provisioning, DSR UNI to OTUk E-NNI grey interface.
  • Subscription to Notification Service for Alarm and Threshold Crossing Alert (TCA) events.
  • Notification of Alarm and Threshold Crossing Alert (TCA) events

The Reference Implementation Agreement has also been supplemented with a spreadsheet specifying over 100 standard Alarms and PM Parameters.

TR-548 v1.1

TR-548 v1.1 provides requirements, use cases and guidelines for use of TAPI 2.1.3 Streaming Yang. TAPI Streaming is an alternative to the traditional notification mechanism specified in TR-547 covering all TAPI modelled information including NEPs CEPs, equipment etc. as defined in TR-547 and associated Yang, and provides a specific alarm structure that enables alarm streaming.  TAPI Streaming offers various stream strategies. TR-548 v1.1 focuses on a stream strategy (compacted log with whole entity on change) designed to enable a TAPI client to gain and maintain alignment (eventual consistency) with the relevant current state of the network, as presented via the TAPI Context, by simply connecting to the appropriate streams. With this strategy, there is no need to get information for initial alignment as the stream is based upon a compacted log that essentially maintains the current state in the stream. Each stream also provides ongoing reporting of change so as to enable the TAPI client to maintain alignment.

Interest from TIP

 TIP MUST (Mandatory Use Case Requirements for SDN for Transport) subgroup, an operator-led subgroup aiming to accelerate and drive the adoption of SDN standards for transport technologies, is ​referencing TAPI defined use cases in TR-547 and TR-548 as part of the technical requirements defined to evaluate SDN commercial solutions ​following TIP’s Test and Validation framework. In the short term, MUST will release the first Ribbon ​Eligibility process for Optical SDN Controllers to evaluate their support of the standard Northbound Interface based on TAPI models. The MUST subgroup will also continue collaborating with the ONF at the definition of new versions of the TAPI models and Reference Implementations towards the standardization of the features and use cases of interest of the operators participating in MUST.
