Nine New Mplify Standards Ratified, With Editing and Contribution from Amartus
February 2026 brought a landmark moment for open network standards. Nine new Mplify specifications were ratified by the Board of Directors on 17 February 2026, following a Letter Ballot and Draft Specifications Review Period by Mplify Members — the culmination of months of intensive collaboration across the industry. We’re proud that our team of Solution Architects* played a central role in shaping this release — both as editors and contributors — working side by side with peers from other leading Mplify member organizations.

This batch of standards covers a broad range of network automation capabilities — from performance monitoring and fault management to streaming, service testing, and security — extending them into concrete, implementable API specifications across the LSO Legato, Allegro, and Interlude reference points. Together, they give network operators and service providers the tools to automate, monitor, and validate services at scale.
Standards we helped edit in February 2026
As editors, Amartus’ specialists worked closely with contributors across Mplify member organizations to shape the technical direction, consistency, and quality of the following five Developer Guides:
Mplify 143 – LSO Allegro, LSO Interlude, and LSO Legato Performance Monitoring API – Developer Guide
This guide provides detailed API specifications for implementing performance monitoring across key LSO reference points. Network operators can integrate these APIs to track real-time service metrics and optimize network performance for enterprise applications.
This standard defines APIs for generating and handling alarms and threshold-based alerts across standardized services. Businesses can automate fault detection and immediate response actions, reducing downtime and operational costs.
Mplify 147 – LSO Allegro, LSO Interlude, and LSO Legato Streaming Management API – Developer Guide
It specifies APIs for managing continuous streaming of network and service data in real time. Service providers can implement these APIs to monitor live traffic, optimize bandwidth allocation, and ensure consistent end-user experiences.
Mplify 148 – LSO Allegro, LSO Interlude and LSO Legato Fault Management API – Developer Guide
This guide defines API methods for detecting, reporting, and resolving faults in standardized services. Companies can use it to quickly pinpoint network issues and maintain high service availability for customers.
It provides API specifications for testing and validating service functions across multiple LSO reference points. Businesses can leverage these APIs to confirm service behavior and compliance before deployment, minimizing operational risk.
Standards we contributed to in February 2026
Beyond the editorial role, our team brought their expertise in open standard APIs and network automation to the following three standards as technical contributors:
Mplify 133.1 – Allegro, Interlude and Legato Fault Management and Performance Monitoring BR&UC
This standard outlines the business requirements and use cases for implementing fault and performance monitoring via LSO APIs across multiple reference points. Enterprises can use it to proactively detect network issues and ensure reliable service performance for their customers.
It describes how service function testing capabilities should be deployed through LSO APIs to validate standardized services. Organizations can use these guidelines to verify end-to-end service quality and accelerate service rollout with confidence.
Mplify 164 – Internet Access Product Attributes and Use Cases
This standard defines a consistent data model for Internet Access services, including product attributes and service parameters. It enables service providers to efficiently package, sell, and provision standardized Internet Access offerings across multiple operators.
(Note: Mplify 169 – Security Service Edge Framework also appeared in the February 2026 release, specifying the key service attributes required to build Security Service Edge (SSE) solutions.)

Building on a strong foundation: our November 2025 contributions
The February 2026 release doesn’t stand alone. It is part of a sustained, long-term effort by Mplify members and contributors to build a comprehensive open standards ecosystem for network automation. In November 2025, our team was already deeply involved — editing 13 standards and contributing to one more, spanning the LSO Cantata, Sonata, Allegro, Interlude, and Legato reference points. Here’s a full picture of that prior wave, which laid much of the groundwork for what followed.

What this means going forward
This is what sustained, expert-level engagement with open standards looks like in practice. Across two major release cycles, our Solution Architects and peers across the Mplify community have helped build the API infrastructure that network operators, service providers, and enterprises worldwide will rely on to automate and manage services. From fault detection and performance monitoring to service ordering, billing, and security — the coverage is broad, the detail is deep, and the impact is real.
We’ll continue to track and contribute to Mplify’s evolving standards program. If you’re working on LSO implementations or want to understand how these standards apply to your environment, we’d love to talk.
