Introducing NexusWave: Seamless High-Speed Connectivity

NexusWave provides fast, always-on connectivity by seamlessly integrating multiple high-speed networks in real time. By combining Global Xpress (GX) Ka-band, low-Earth orbit (LEO) services, and as-available coastal LTE service, and adding an extra layer of L-band for resilience, NexusWave ensures robust and continuous connectivity for maritime operations. This integration leverages Livewire’s RazorLink SD-WAN technology to orchestrate and bond these diverse network sources, delivering a seamless and reliable communication experience.

RazorLink SD-WAN: The Backbone of NexusWave

RazorLink SD-WAN is designed to address hybrid networking over challenging networks. With a heritage in providing hybrid satellite and cellular SD-WAN networking within demanding maritime and vehicular environments, RazorLink excels across diverse global architectures. The bonded network, comprising GEO, LEO, LTE, and L-band, is underpinned by RazorLink’s SD-WAN implementation, an engineering feat capable of orchestrating and bonding multiple network sources together in real time.

Resilience and Performance: Key Features of RazorLink SD-WAN

  1. High Resilience to Underlay Degradation: The SD-WAN fabric is highly resilient to underlay degradation and failure. Single TCP connections are maintained and accelerated, assuming some level of connectivity exists, regardless of underlay availability and performance. This resilience ensures continuous and reliable access to cloud services, even in remote maritime environments.
  2. Smart Networking Protocol (SNP): Traffic scheduling is handled by the RazorLink Smart Networking Protocol (SNP), a proprietary transmission protocol that facilitates packet-by-packet intelligence and control. SNP provides unparalleled mobility and optimised use of network underlays under ever-changing link conditions.
  3. Advanced Traffic Classification: RazorLink SD-WAN allows for advanced traffic classification and underlay management. Applications can be allocated to any number or specific combinations of bonded underlay networks, with seamless transitions and re-allocations. This flexibility ensures that critical applications receive the necessary bandwidth and priority.
  4. Real-time Data Insights: A rich and expansive data set is available in real-time directly from the SNP transmission protocol. This data enables advanced control over Quality of Service (QoS) and traffic-steering policies, providing comprehensive assurance data for optimised network performance.
  5. Scalability and Flexibility: The full feature set of RazorLink SD-WAN is available regardless of platform deployment, from micro ARM-based systems, including Raspberry Pi, to data centre server farms. RazorLink SD-WAN provides an elastic fabric with scaling limits determined only by the hosting infrastructure. Full separation (layer 2 and layer 3) is maintained across the entire multi-tenant-aware SD-WAN fabric.

Enhancing Maritime Communications with NexusWave

Inmarsat’s NexusWave makes the process simple, consolidating everything your fleet may need into one unified solution. With the power of RazorLink SD-WAN, NexusWave offers a range of benefits tailored to the needs of maritime operations:

  • Network Bonding: By bonding 3G, 4G, Wi-Fi, DSL, and satellite connections, NexusWave increases available bandwidth and provides a backup network for critical applications. This bonding capability ensures high-speed and resilient connectivity, even in the most remote locations.
  • Network Resilience: RazorLink protocols overcome the limitations of using UDP across WANs, resulting in more efficient use of network capacity and lower latency. This resilience is crucial for maintaining reliable communications in challenging maritime environments.
  • Network Acceleration: NexusWave overcomes delays and packet loss that can occur when operating over a WAN, radically improving the performance of applications. This network acceleration is vital for ensuring smooth and efficient cloud access.
  • Network Prioritisation: NexusWave prioritises traffic so the most important data is delivered first. For example, audio can be given higher priority than video, or vital signs telemetry over imagery. This prioritisation ensures that critical data is transmitted without delay.
  • Network Security: RazorLink Technology encrypts application data using AES, maintaining maximum performance while ensuring data security. This encryption is essential for protecting sensitive maritime communications.
  • Network Statistics & Accounting: RazorLink provides real-time bandwidth statistics and accounting information without the need for custom libraries or complicated APIs. This feature allows for easy monitoring and optimisation of network performance.

Comprehensive Management and Control

The RazorLink SD-WAN solution offers a range of features designed for highly mobile platforms and challenging environments:

  • Highly Mobile Platforms: RazorLink SD-WAN is designed for platforms that require mobility and flexibility, making it ideal for maritime applications.
  • Optional Central Management: Communication and management by central services are entirely optional, providing flexibility in deployment and operation.
  • Horizontal and Vertical Scaling: With no hard limit on fabric capacity, RazorLink SD-WAN offers horizontal and vertical scaling options, ensuring that it can grow with your needs.
  • True Aggregation: RazorLink SD-WAN provides true aggregation, offering sum-of-all-parts bonding, even when combining diverse link combinations. This aggregation ensures maximum bandwidth utilisation and resilience.
  • Low Overheads: Compared to competitive products, RazorLink SD-WAN has very low overheads, making it a cost-effective solution.
  • Future-Proof Architecture: RazorLink SD-WAN supports 5G, 6G, LEO, and beyond. Any IP-capable underlay can be accommodated, with no restriction on the number of supported underlays.
  • Near-Zero Configuration: Supporting new underlays requires near-zero configuration, ensuring easy integration and deployment.
  • Effective TCP Acceleration: Highly effective TCP acceleration improves performance over any connection, enhancing the speed and reliability of data transfers.
  • Multi-tenant Networking: RazorLink SD-WAN offers multi-tenant networking that is seamlessly decoupled from the underlays, providing transparent resilience to underlay transitions.
  • Granular Control: Granular control over service allocation and airtime usage allows for precise management of network resources.
  • Rich Data for Service Assurance: Rich data facilitates service assurance over hybrid connections, providing proof of service delivery and ensuring high performance.
  • On-the-fly Control: Comprehensive on-the-fly control over QoS, traffic-steering, and aggregation is effective in real-time, with programmatic interfaces allowing for highly customisable integration and control.
  • Increased Reliability: Vastly increased service reliability and resilience to failures ensure continuous and dependable network performance.
  • Traffic Shaping and QoS Profiles: Granular definition of traffic shaping and QoS profiles is essential for the effective implementation of customer service level agreements (SLAs).
