Beaverton, USA, August 30, 2022 – HomeGrid Forum announced the release of VectorBoost as open source software for the GiGAWire profile that manages crosstalk mitigation in broadband access networks. The initiative will accelerate the development of ITU-T-based network solutions G.hn standards extended to the multi-dwelling unit (MDU) environment, including large apartment complexes and office buildings, as well as single family unit (SFU) and fiber extension scenarios using the profile GiGAWire. It provides crosstalk attenuation and auto-pairing features to support multiple users using bundled cables.
VectorBoost is the feature of G.hn Access that allows the twisted pair copper telephone wire to reach its maximum capacity, even when there is crosstalk from other subscribers in the same filing cabinet. It can ensure the optimal allocation of resources between neighboring lines according to their real-time traffic needs and can operate locally on a GAM (G.hn Access Multiplexer) or in the cloud. VectorBoost can be adjusted to meet service provider requirements and can be easily upgraded as more computing resources become available in the operator’s private cloud. In addition to mitigating crosstalk between pairs of a copper bonder, VectorBoost optimizes spectrum allocation by boosting spectrum only for subscribers who need additional bandwidth. Coupled with Coordinated Dynamic Time Allocation (cDTA), it provides the optimal real-time bandwidth allocation for each G.hn link.
With the GiGAWire Solution, service providers can leverage G.hn Access technology over existing cables to cost-effectively deliver last-mile infrastructure in areas where fiber cannot be deployed to customer premises. G.hn deployment options capitalize on complementary architectures to extend fiber networks with P2P and point-to-multipoint (P2MP) telephony and coaxial infrastructures and topologies.
“The announcement of the open source software responds to network operators expressing an urgent need to accelerate their deployments with interoperable G.hn equipment that ensures optimal allocation of power, spectrum and slot utilization between subscriber lines,” said the president of the HomeGrid Forum. Livia Rosu. “HomeGrid Forum’s GiGAWire GitHub launch is focused on the innovative G.hn access technology enabling service providers and system vendors to leverage existing copper wiring in buildings, such as telephone lines and coaxial cables, while further customizing their facilities and equipment”
Paul Arola, GiGAWire Task Force Chair and TELUS Senior Design Specialist, added, “The GiGAWire Task Force helps accelerate deployments of G.hn access scenarios, enabling service providers to deliver advanced broadband access to SFUs and MDUs that cannot be served. with fiber all the way. We encourage service providers to leverage their coax and twisted pair infrastructure for the latest network segment and capitalize on the VectorBoost open source code for the GiGAWire profile to further enhance their implementations for network function virtualization and deployments requiring crosstalk mitigation.
The VectorBoost compute engine runs as part of GAM firmware or in a cloud server and communicates with each of the VectorBoost drivers that run in the GAM. The innovation collects traffic updates from all drivers, analyzes crosstalk parameters, and calculates the optimal allocation of power, spectrum, and slot utilization to ensure that capacity on all lines corresponds to high traffic demands.
Statistical crosstalk processing is based on tracking the real-time data rates sent and received on each subscriber line, then adapting the power level used in each link in real time to avoid the transmission of fictitious signals , thus minimizing the amount of crosstalk that each link generates on neighboring links.
The implementation is based on MaxLinearThe cloud-based VectorBoost architecture, which is capable of scaling from single-port deployments to hundreds of lines in a high-density MDU topology. By leveraging an open-source design, bug fixes and new feature additions have already been made to the VectorBoost code base. These code changes are reviewed and approved by the HomeGrid Forum’s GiGAWire Working Group.
Dr. Len Dauphinee, Vice President and CTO of Broadband Products at MaxLinear adds, “A well-designed G.hn access system should dynamically reallocate network capacity between users to maximize peak speed for users who need capacity at any given time, while minimizing wasted resources for users who do not need capacity due to low traffic requirements. MaxLinear designed the cloud-based VectorBoost architecture to help adapt broadband access installations to high-density MDU topologies requiring crosstalk mitigation. We are delighted to have provided the foundation for the GiGAWire solution. The release of the VectorBoost open source code program supports the acceleration of service provider deployments.
