Beaverton, USA, August 30, 2022 – HomeGrid Forum announced the release of VectorBoost as an open source software for GiGAWire profiles that manages crosstalk throttling in broadband access networks. The initiative will develop network solutions based on ITU-T. speed up G.hn standards extended to the Multi Dwelling Units (MDUs) environment, including large apartment complexes and office buildings, as well as Single Family Units (SFUs) and Fiber Extenders scenarios using the GiGAWire profile. It provides crosstalk limitation and auto-linking functions to support multiple users using bundled cables.
VectorBoost is the feature of G.hn Access that allows twisted copper telephone wires to reach their maximum capacity even with crosstalk from other subscribers in the same binder. It can ensure optimal allocation of resources between the adjacent lines according to their real-time traffic needs and can run locally on a GAM (G.hn Access Multiplexer) or in the cloud. VectorBoost can be tuned to meet the demands of service providers and can be easily upgraded as more compute resources become available in the provider’s private cloud. In addition to reducing crosstalk between copper binder pairs, VectorBoost optimizes spectrum allocation by amplifying spectrum only for subscribers who need additional bandwidth. Combined with coordinated Dynamic Time Allocation (cDTA), it delivers the optimal bandwidth allocation in real time for each G.hn link.
The GiGAWire solution enables service providers to leverage G.hn Access technology over existing cables to cost-effectively provide last-mile infrastructure in areas where fiber cannot be deployed all the way to the customer. G.hn’s deployment options take advantage of complementary architectures to extend fiber networks with Phoneline and Coax-based P2P and Point-to-Multipoint (P2MP) infrastructure and topologies.
“The announcement of the open source software is in response to the urgent need of network operators to accelerate their deployments with interoperable G.hn equipment that ensures optimal allocation of power, spectrum and timeslot usage between subscriber lines,” said HomeGrid Forum President Livia Rosu. “The launch of the HomeGrid Forum’s GiGAWire GitHub focuses on innovating G.hn Access technology, enabling service providers and system vendors to leverage existing copper wiring in buildings, such as telephone lines and coaxial cables, and further customize their installations and equipment”
Paul Arola, Chair of the GiGAWire Task Force and Senior Design Specialist at TELUS added: “The GiGAWire Task Force is helping to accelerate the implementation of G.hn Access scenarios, enabling service providers to deliver advanced broadband access services to SFUs and MDUs that cannot be serviced all with fiber. We encourage service providers to leverage their coax and twisted pair infrastructure for the last network segment and take advantage of the VectorBoost open source code for the GiGAWire profile to further improve their network function virtualization implementations and implementations that require crosstalk mitigation.”
The VectorBoost Compute Engine runs as part of a GAM firmware or in a cloud server and communicates with each of the VectorBoost drivers running in the GAM. The innovation will collect traffic updates from all drivers, analyze the crosstalk parameters and calculate the optimal allocation of power, spectrum and time slot usage to ensure capacity across all lines matches the high traffic demands.
The statistical treatment of crosstalk relies on tracking the real-time data rates sent and received over each subscriber line, then adjusting in real time the power level used in each link to avoid the transmission of dummy signals, reducing the amount of crosstalk is minimized is minimized. each link generates on adjacent links.
The implementation is based on MaxLinearCloud-based VectorBoost architecture, which scales from single-port deployments to hundreds of lines in high-density MDUs topology. Using an open source design, bug fixes and new additions have already been made to the VectorBoost code base. These code changes are reviewed and approved by the HomeGrid Forum GiGAWire Task Force.
dr. Len Dauphinee, vice president and CTO of broadband products at MaxLinear added, “A well-designed G.hn Access system should dynamically reallocate network capacity to users to maximize peak speed for those users who need capacity at any given time, while minimizing the resources wasted on users who do not need capacity due to the low traffic needs. MaxLinear designed the cloud-based VectorBoost architecture to scale broadband access installations to high-density MDU topologies that require crosstalk mitigation. We are delighted to have laid the foundation for the GiGAWire solution. The release of the VectorBoost open-source code program comes to support the acceleration of service provider deployments.”
