RazorLink SD-WAN

RazorLink SD-WAN

RazorLink SD-WAN has been designed to address hybrid networking over challenging networks, and with a heritage in providing hybrid satellite and cellular SD-WAN networking within demanding maritime and vehicular environments, and across diverse global architectures.

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.

Traffic scheduling is handled by the RazorLink Smart Networking Protocol (SNP) – a proprietary transmission protocol, facilitating packet-by-packet intelligence and control, and unparalleled mobility, providing optimised use of network underlays under ever changing link conditions.

Advanced traffic classification and underlay management allows for applications to be allocated to any number or a specific combination of bonded underlay networks, and underlay transitions or re-allocations are seamless to the application.

A rich and expansive data set is available in real-time, directly from the SNP transmission protocol, allowing for advanced control over QoS and traffic-steering policy, and comprehensive assurance data.

The full feature set of RazorLink SD-WAN is available regardless of platform deployment – from micro ARM-based systems, including Raspberry Pi, up to data centre server farms.

RazorLink SD-WAN provides an elastic fabric, with scaling limits determined only by the limits of the hosting infrastructure.  Full separation (layer 2 & layer 3) is maintained across the entire multi-tenant-aware SD-WAN fabric.

Key features

  • Hybrid WAN & WAN Optimisation


Bond 3G, 4G, Wi-Fi, DSL and satellite to increase the available bandwidth and to offer a backup network for your critical application.


Overcome the delay and packet loss that can occur when operating over a WAN, radically improving the performance of your applications.


RazorLink Technology can encrypt your application data using AES and still maintain maximum performance.


RazorLink protocols overcome the limitations of using UDP across WANs resulting in more efficient use of network capacity and lower latency.


Prioritise traffic so the most important data is delivered first. Give audio higher priority than video or vital signs telemetry over imagery.


RazorLink provides bandwidth statistics and accounting information in real time without the need for any custom libraries of a complicated API.

The RazorLink SD-WAN solution offers a range of applicable features:

  • Designed for highly mobile platforms
  • Communication/management by central services is entirely optional
  • Horizontal and vertical scaling options, with no hard limit on fabric capacity
  • True aggregation, providing sum-of-all-parts bonding, even when combining diverse link combinations
  • Very low overheads compared to competitive products
  • Future-proof architecture supporting 5G, 6G, LEO and beyond – any IP-capable underlay can be accommodated, with no restriction on the number of supported underlays.
  • Software structure can support non-IP based underlays that are capable of sending/receiving a ‘data packet’
  • Near-zero configuration required to support new underlays
  • Highly effective TCP acceleration
  • Multi-tenant networking that is seamlessly decoupled from the underlays, and transparently resilient to underlay transitions
  • Granular control over service allocation and airtime usage
  • Rich data to facilitate service assurance over hybrid connections, and provide proof of service delivery
  • Comprehensive on-the-fly control over QoS, traffic-steering, and aggregation – effective in real-time, and with programmatic interfaces allowing for highly customisable integration and control.
  • Vastly increased service reliability and resilience to failures
  • Granular definition of traffic shaping and QoS profiles, essential for the effective implementation of customer service level agreements (SLAs)
