Muse Multilayer Automation Platform
Mission Critical Defense IP Optical Solutions
Decision-making on the modern battlefield requires real-time information to be made available when and where it is required. This data must then be analyzed in real time to allow informed decisions and provide the control of network-dependent weapons such as drones, robots, and unmanned vehicles. A combination of IP, Packet, and Optical networking provides both the agility to link the data generated from various data sources and systems to multiple destinations as well as the capacity required to transport bulk data over long distances with ultra-low latency.
Ribbon provides tailor-made, secure, hardened, field-proven defense solutions. These solutions integrate intelligent optical networking with agile IP/Packet connectivity to provide a converged, secure communication network.
- Neptune/NPT is a multiservice IP/Packet platform supporting both modern devices as well as legacy systems
- Apollo programmable and open optical networks satisfy ever-growing demands for secure bandwidth
- The Muse™ software suite allows seamless operation and automation across Apollo and Neptune.
Ribbon provides a single integrated communications network, able to support video surveillance systems, command and control networks, sensors, radar, and smart IoT devices. Our unique TDM-to-IP solutions support integration of legacy TDM-based systems as well as their migration. Neptune’s unique Multistack MPLS capabilities allow mission-critical and non-mission-critical communications on the same network. MPLS-TP provides the deterministic transport needed for mission-critical applications and IP/MPLS provides the dynamic IP transport expected for non-mission-critical IT applications.

Cyber and Network Security
In the ever-evolving landscape of modern defense, the intersection of cyber and network security has become paramount. With threats growing in complexity and scope, safeguarding digital infrastructures has become a strategic imperative. Network security forms the backbone of effective defense strategies, ensuring seamless communication across secure channels without compromising sensitive information.
Defense operations now depend on the agility and resilience of their network infrastructures. By leveraging Ribbon’s capabilities, military organizations can ensure secure and efficient communication, coordinate multi-domain operations, and maintain the highest levels of cyber defense in an increasingly digitized battlespace.
