The LF Broadband community is pleased to announce the release of VOLTHA 2.13, packed with significant advancements that enhance performance, scalability, and production readiness. This release introduces the Voltha Go Controller (VGC), optimizes CPU and memory usage in key adapters, and includes multiple enhancements and bug fixes that further solidify VOLTHA/SEBA’s readiness for large-scale operator deployments. The full release notes are also available.

Key Highlights of VOLTHA 2.13

1. Introducing Voltha Go Controller (VGC): A New SDN Controller

VOLTHA 2.13 introduces the Voltha Go Controller (VGC) as a new SDN controller, offering better performance and improved stability compared to ONOS. While ONOS remains available in this release, VGC provides an alternative that enhances system efficiency and reliability, ensuring smoother network operations.

2. Enhanced CPU & Memory Utilization

To reduce cloud resource consumption and optimize data center operations, VOLTHA 2.13 includes crucial improvements in CPU and memory utilization:

  • openonu-adapter: Significant memory consumption optimizations have been implemented to improve overall efficiency.
  • openolt-adapter: High CPU and memory usage during reconciliation have been addressed, leading to better resource utilization and performance stability.

These enhancements reduce infrastructure costs while ensuring VOLTHA’s ability to scale effectively in production environments.

Additional Enhancements & Fixes

New Features

  • Added interfaces to protos to enable offloading of PPPoEIA and DHCP RA apps onto the OLT.
  • Implemented voltctl functionality to fetch statistics of offloaded applications.
  • Introduced the ability to avoid reconciling Managed Entities (MEs) with ONT after an openonu-adapter restart.
  • Added getOnudistance implementation in voltctl to retrieve ONU distance metrics.

Bug Fixes & Known Issues

  • Resolved several issues related to reconciliation, ONU software upgrades, device deletion, and reboots.
  • Fixed multiple bugs to ensure smoother operations and improved stability.
  • Known issues include multicast not working for GPON TT test pipeline (VOL-5427) and unexpected ONU states in test cases (VOL-5426).

Why VOLTHA 2.13 Matters

The VOLTHA 2.13 release represents a significant step towards enhancing SDN-controlled broadband access networks. With the introduction of VGC, substantial CPU and memory optimizations, and multiple reliability improvements, VOLTHA continues to evolve as a production-ready, scalable solution for broadband network operators.
