Anuket aims to accelerate infrastructure compliance and interoperability

LF Networking (LFN) has merged CNTT (The Cloud iNfrastructure Telco Taskforce, which provided reference models and architectures for both virtual machine and containerized network functions) and OPNFV (the Open Platform for NFV, which reduced time to integrate and deploy NFV infrastructure and onboard VNF/CNFs), into a new open source project called Anuket.

Anuket's mission is to deliver tools and artifacts to "empower the global communications community to deliver compliant network services faster, more reliably and securely, and accelerate the transformation to cloud native infrastructures." The project delivers standardized reference infrastructure specifications and conformance frameworks for virtualized and cloud native network functions, enabling faster and more robust onboarding into production, reducing costs, and accelerating telecom digital transformation. 

OPNFV’s final stand-alone release, Jerma, delivered in December, delivered CNTT-ready capabilities, including an initial cloud native Reference Implementation and integration of cloud native testing aligned with CNTT’s R2 work. Elbrus, CNTT’s final release, planned by early February, initiates a number of new work areas, including infrastructure automation and observability, hardware management, and hardware abstraction and network fabric programmability. 

LFN said the new group will continue OPNFV’s legacy of operating upstream with collaboration across other open source projects (such as LF Networking, LF Edge, CNCF, LF AI, ODIM and other industry organizations and standards bodies). Anuket will also preserve CNTT’s close working relationship with GSMA, who will continue to publish the project’s Reference Model work.  

“It’s incredible to see the evolution of what began as the Open Platform for Network Functions Virtualization over six years ago,” said Heather Kirksey, vice president of Community and Ecosystem Development at the Linux Foundation. “With Anuket, we are making it easier and more efficient for CSPs to transform their networks and save money, with one, end-to-end platform.”

“The Anuket project is unique in covering Operator requirements collection and normalisation, subsequent open-source software development, through to Industry certification programs of ecosystem implementations, all under a single initiative,” said Walter Kozlowski, Anuket Technical Steering Committee co-chair and Principal, Cloud Infrastructure Architecture, at Telstra. “I am proud to serve in the role of a co-chair of its Technical Steering Committee, and I am excited by the unique opportunity this project creates for my company and for the whole industry, in the area of network transformation and related telco open infrastructure.”

“I’m very excited about the merging of CNTT and OPNFV into a single entity,” said Andre Fuetsch, CTO, Network Services, AT&T. “This move will empower the global communications community by bringing together reference cloud infrastructure models and architectures with conformance programs and tools to deliver network services faster, more reliably, and securely. The collaborative spirit of this open source development effort will help grow the communications industry to new levels of service for all stakeholders. Empowering the global society to benefit. We at AT&T are proud to be part of this initiative and look forward to supporting Anuket in the coming years.”

Cignal AI: Big shifts in spending on optical and packet transport

Expenditures by North American cloud and colocation operators on optical and packet transport equipment declined 20 percent year over year in the third quarter of 2020 (3Q20), while incumbent operator spending increased 2 percent, according to the 3Q20 Transport Customer Markets Report from market research firm Cignal AI.

“Equipment suppliers to cloud operators report that sales in the third quarter were depressed because service providers absorbed capacity on networks that were built during the first half of 2020,” said Scott Wilkinson, lead analyst at Cignal AI. “Both incumbent and cloud operators, especially in North America, spent significantly more of their annual budget than typical in the first half of the year.”

More Key Findings from the 3Q20 Transport Customer Markets Report

  • After uncharacteristically strong growth in 2Q20, sales to cloud and colocation operators in Asia Pacific (APAC) rose dramatically again in the third quarter
  • Despite a year-over-year decline in sales, Ciena maintained its worldwide market share leadership in sales to cloud and colocation operators in 3Q20
  • The fourth quarter is expected to be challenging for sales outside APAC, with traditional telco and cloud and colocation purchases anticipated to wane worldwide

ONF releases SD-RAN v1.0 for Open RAN

The ONF released SD-RAN v1.0, the first software release for its cloud-native exemplar platform for software-defined RAN that is consistent with the O-RAN architecture.  

The ONF’s first release of the SD-RAN project implements a minimal O-RAN consistent end-to-end mobile RAN stack intended as a development environment for building xApps for the emerging Open RAN ecosystem. It includes µONOS-RIC (ONF’s nRT-RIC based on µONOS) which interacts with RAN hardware (RU/DU/CU) via O-RAN consistent interfaces (E2AP), encodings (ASN.1), transport-protocols (SCTP) and Service Models (SMs). The release also includes a white-box based RU/DU/CU solution, leveraging OAI software, that has been enhanced to expose O-RAN consistent interfaces and protocols. To integrate with µONOS-RIC, the CU-CP RAN component has been enhanced with an E2 Agent that exposes the KPM-SM information-elements to xApps that connect to the nRT-RIC and subscribe to the KPM service. image png

Secondly, an end-to-end solution is provided. The RAN components interact with Samsung Android handsets as well as OAI User Element (UE) emulation software. For mobile core (EPC) integration, the RAN components interact with ONF’s OMEC mobile core. 

This release also includes the beginnings of an app-SDK which can ease the process of creating xApps that are portable across different nRT-RIC platforms.  As part of ONF’s commitment to supporting the O-RAN Alliance, this SDK is being shared with the O-RAN Software Community to support and promote availability of interoperable xApps and rApps that can work with a selection of nRT-RIC implementations. 

Finally, the solution can be instantiated in two distinct forms to create nimble development environments.  SD-RAN can run on reference white-box hardware, and it can also be instantiated entirely in a virtualized form (in a VM or server) in a distribution package called RiaB (sdRan-in-a-Box). The entire distribution including xApp, µONOS-RIC components, CU/DU, UE and OMEC can be instantiated within RiaB with just a few simple commands.

ONF launches 5G SD-RAN Project

The Open Networking Foundation (ONF) has launched an SD-RAN project with the aim of building an open source Near Real-Time RAN Intelligent Controller (nRT-RIC) compatible with the O-RAN architecture as well ONF’s existing base cloud-native solutions leveraging disaggregation and whitebox hardware.

ONF said its goal is to foster open source software platforms and multi-vendor solutions for mobile 4G and 5G RAN deployments.

Central to the project is the development of an open source near-real time RIC called µONOS-RIC (pronounced “micro-ONOS-RIC”).

µONOS is a microservices-based SDN controller created by the refactoring and enhancement of ONOS, the leading SDN controller for operators in production tier-1 networks worldwide.  µONOS-RIC is built on µONOS, and hence features a cloud-native design supporting active-active clustering for scalability, performance and high availability along with the real-time capabilities needed for intelligent RAN control. The O-RAN ALLIANCE E2 interface is used to interface between µONOS-RIC and vendor supplied RAN RU/DU/CU RAN components.

Carriers would be able to run new "xApps" on top of the µONOS-RIC.  These open xApps could provide functionality that traditionally has been implemented in vendor-proprietary implementations, including providing visibility and control over the RAN.

Significantly, the ONF's SD-RAN project is backed by AT&T, China Mobile, China Unicom, Deutsche Telekom, Facebook, Google, Intel, NTT, Radisys and Sercomm.

A working skeleton prototype of the µONOS-RIC controller is already running above a RAN emulation platform through the E2 interface.  ONF has demonstrated handover and load balancing at scale, supporting over 100 base stations and 100,000 user devices with less than 50ms handover latency (less than 10ms latency for 99% of all handovers). Field trials are expected by early 2021.

South Korea's LG U+ deploys 600G on a single wavelength with Ciena

LG U+ has deployed a newly constructed and dedicated nationwide ROADM backbone network leveraging Ciena’s WaveLogic 5 Extreme and WaveLogic Ai coherent optical solutions and becoming the first carrier in Korea to deploy 600G on a single wavelength for long haul distances.

LG U+ is applying OTDR (Optical Time Domain Reflectometer) technology to all sections of the backbone network for real-time line condition monitoring. In addition, Ciena’s 6500 ROADM equipment will provide disaster recovery line services to public government, financial institutions and compute centers of large enterprises through third party interworking certification. LG U+ can also provide a dedicated line service with enhanced security through optical transport encryption.

LGU+ will be using Ciena’s Manage, Control and Plan (MCP) SDN controller to be able to automate service delivery via next-generation OPEN APIs to improve customer experience and increase operational efficiencies.

Sung-cheol Koo who’s in charge of LG U+’s wired business said, “Amid the expansion of cloud services such as telecommuting, video conferencing and remote classes, we are building a new backbone network that can accommodate the needs of various corporate customers. With a flexible and stable transmission network, we expect that companies can provide a higher level of service."
