The explosion in development of Machine Learning (ML) and Software Defined Networks (SDN) was driven by Domain Specific Languages (DSL) and automation. This methodology is described by the 2017 ACM A.M. Turing Award recipients, Profs John Hennessy and David Patterson [Link: https://www.acm.org/hennessy-patterson-turing-lecture ]. By decoupling the system development from the implementation details, the DSL approach has allowed domain experts to rapidly develop specific solutions for their system needs. This methodology has now reached wireless communications systems with Cirrus360’s RDSL™ (Real time Domain Specific Language) and Intelligent Automation technology.
 
The success of machine learning with TensorFlow, PyTorch and other open frameworks and languages is a great example of application of DSL plus automation. Cirrus360’s patented intent driven Radio Access Networks (RAN) automation platform extends DSL plus automation to real time systems like RAN, including Layers 1 and 2 (PHY and MAC). It unlocks deployment specific optimizations in open RAN for 5G edge. These optimizations leverage the needs of specific use cases and market segments and drive efficiencies in power consumption, hardware usage, reliability, integration effort and costs.

Cirrus360 combines the advantages of open RAN with cloud based automation to serve the business needs of end users, especially small and medium businesses (SMBs). The automation described in the previous section, generates a customized 5G connectivity solution to meet the cost and performance that a business needs (not less, not more). This connectivity solution is not only integrated with compute, but also optimized for the edge applications specific to the SMB’s market segment.

 

Cirrus360’s automation technology, extended to the full Private 5G Edge stack, is the unique differentiator for SMBs as it translates to zero touch deployments, explainability at each stage of deployment and operations, and security and reliability guarantees via formal techniques.

RDSL™ enables multi element open RAN integration and optimization, while protecting intellectual property of individual vendors. This includes Layer 1 (PHY) and Layer 2 (MAC) – the most difficult to implement parts of the 5G stack – and applies to both private 5G and macro networks. RDSL™ is essential for efficient system integration and complements the O-RAN Alliance's open interfaces and joint interoperability testing.

 

RDSL™ is a declarative language that is used to express 5G RAN flows in a hardware agnostic manner. RDSL™ supports deployment intent regarding the target traffic model and constraints such as latency and QoS. RDSL™ also includes a simple but powerful 5G domain specific hardware abstraction model that can describe any 5G hardware including general purpose CPUs, inline architectures, or lookaside architectures.

 

With such comprehensive formal representation, RDSL™ has the capabilities to power all stages of RAN development, testing, and operations. These stages include multi-vendor, multiple use cases, and continuously evolving deployment scenarios.
