Ribbon Honored in 2022 Lightwave Innovation Reviews

MuseTM Network Planner enables service providers to maximize network ROI while delivering peak performance

PLANO, TX, Feb. 15, 2022 /PRNewswire/ -- Ribbon Communications Inc. (Nasdaq: RBBN), a global provider of real time communications software and IP optical networking solutions to service providers, enterprises, and critical infrastructure sectors, today announced that its Muse Network Planner (MNP), a key application of Ribbon's cloud-native Muse SDN Orchestrator, was recognized as a high scorer in the 2022 Lightwave Innovation Reviews by an esteemed and experienced panel of judges from the optical communications community.

"Service providers are increasingly challenged to extract value from their networks and Muse Network Planner, with its multilayer algorithmic engine, is proven to help them exceed previous optimization efforts," said Sam Bucci, Ribbon's EVP & General Manager, IP Optical Networks Business Unit. "We're delighted to be recognized once again by the Lightwave Innovation Reviews."

Muse Online Network Planner produces customized, optimized IP Optical networks that address individualized customer requirements for cost, performance and survivability. While it can plan IP and Optical layers individually, it excels at planning multilayer networks, finding for instance the best way to minimize expensive router ports by carrying "pass through" traffic at the less expensive optical layer.

"On behalf of the Lightwave Innovation Reviews, I would like to congratulate Ribbon on

their high-scoring honoree status," said Lightwave Associate Publisher and Editorial Director,

Stephen Hardy. "This competitive program allows Lightwave to celebrate and recognize the most innovative products impacting the optical communications community this year."
