TL;DR
OPlaceRAN is a flexible, cloud-native orchestrator for deploying virtualized Next-Generation Radio Access Networks, supporting dynamic placement of radio functions with validation on real infrastructure, aligning with 5G evolution.
Contribution
The paper introduces OPlaceRAN, a novel orchestrator for vNG-RAN that is agnostic to placement models and supports dynamic, containerized deployment of radio functions.
Findings
OPlaceRAN effectively manages containerized RAN functions in real infrastructure.
It supports multiple functional splits (options 2 and 6).
The solution is compatible with current vNG-RAN design approaches.
Abstract
The fifth-generation mobile evolution enables transformations on Next-Generation Radio Access Networks (NG-RAN). The RAN protocol stack is split into eight disaggregated options combined in three network units, i.e., Central, Distributed, and Radio. Besides that, further advances allow the RAN functions to be virtualized on top of general-purpose hardware, using the concept of virtualized RAN (vRAN). The Combination of NG-RAN and vRAN results in vNG-RAN, which enables the management of the disaggregated units and protocols as a set of radio functions. However, the orchestration-based placement of these radio functions is a challenging issue since the best decision can be determined by multiple constraints involving RAN disaggregation, crosshaul networks requirements, availability of computational resources, etc. This article proposes OPlaceRAN, a vNG-RAN deployment orchestrator framed…
