DexFX: Setting a New Standard for Data Propagation

Revolutionizing Data Transmission

DexFX’s Application Layer Multicast and WAN Acceleration with RMDT Technology


In today’s interconnected and data-driven world, the ability to transmit information efficiently and effectively is more than a convenience—it’s a necessity. As the volume of data generated and consumed continues to soar, traditional data transmission methods are increasingly falling short. This is where Application Layer Multicast shines as a solution, offering a scalable and efficient approach to data propagation.

Dexor is proud to introduce DexFX – Dexor File Exchange, a groundbreaking solution that is set to redefine the landscape of data transmission. Designed for high-speed transmission of Application Layer Multicast traffic and WAN-acceleration, DexFX is built on the robust foundation of RMDT (Reliable Multidestination Transport Protocol) technology.

This innovative solution is engineered to meet the demands of modern enterprises, IoT networks, and data centers, ensuring that data not only reaches its destination but does so quickly, securely, and without overwhelming network resources.

Expanding Reach: One to Ten, Ten to Hundreds

The Data Propagation Cascade

Data propagation example on the graph

DexFX features a standout capability: the Data Propagation Cascade. Imagine a sender effortlessly feeding up to ten destinations with a 1 Gbps data stream each. Besides storing the data, each recipient can send it to the next 10 recipients at the same 10 Gbps total rate. Picture one sending to ten, ten to a hundred, a hundred to a thousand, and so on. This is Data Propagation in action – the same piece of data, propagated to any number of recipients incredibly fast in the form of application layer multicast.

Flexible Delivery Modes for Varied Network Conditions

Coupled and Decoupled Transmissions

DexFX offers two modes of data transmission:

  • Coupled mode: All nodes feed directly over the closest relay hosts for semi-simultaneous delivery without storing and buffering data. One congestion control mechanism on the sender works for all receivers, ensuring semi-simultaneous data delivery to all recipients.
  • Decoupled mode: For more robust, asynchronous delivery. Each cascade chain is a standalone sender and connected to its receivers, which work independently. Each receiver, needing to send data further, runs its own sender and propagates data to its receivers. This scheme is resilient against failures. Some branches of the hierarchical tree may receive data later, allowing hosts with better conditions to process data earlier.
Optimizing Data Paths for Performance and Reliability

Intelligent Connection Probing

Before data transmission begins, DexFX initiates a thorough examination of the connections between hosts. This process involves identifying the latency, capacity, and available bandwidth of each connection. Armed with this information, DexFX meticulously crafts a virtual transmission topology that is tailored to optimize for lower latency, higher bandwidth, or other criteria, depending on the specific use case.

For instance, consider a scenario where it is necessary to send a file from a server in Los Angeles to New York and three servers in Europe—Berlin, Paris, and Amsterdam. In this case, the probing process will identify the latencies between these locations and construct a strategic data path accordingly.

Here’s how it would work: Los Angeles would send data to New York. From New York, the next link in the chain would deliver data to Amsterdam. Finally, the third link of the chain would distribute data from Amsterdam to Paris and Berlin simultaneously. This stands in contrast to the traditional point-to-multipoint approach, where data would be transferred from LA to all destinations at once.

With DexFX, high-delay links are traversed by the traffic only once—such as LA to NY and NY to Amsterdam. For the low-latency, domestic connections, data is distributed in a straightforward point-to-multipoint mode. This intelligent design minimizes delays and maximizes efficiency, ensuring that data reaches its destinations swiftly and reliably.

A Foundation of Speed, Security, and Reliability

Data Propagation Built on RMDT Technology

DexFX uses the reliable Application layer multicast approach, based on RMDT (Reliable Multidestination Transport Protocol) technology. This brings several key advantages:

  • High-speed Data Transmission: RMDT is designed for speed, ensuring quick and efficient large volumes of data transmission.
  • WAN-Acceleration: RMDT optimizes data transmission over Wide Area Networks (WAN), ideal for long-distance data sending without speed or quality degradation.
  • Reliability and Security: RMDT ensures secure data transmission that arrives intact and without loss or corruption, even in challenging network conditions.


As industries continue to integrate IoT into their operations, the need for efficient and reliable data transmission mechanisms becomes paramount. RMDT, with its High-speed Data Transmission and WAN-Acceleration capabilities, emerges as a leading solution to address these challenges. Whether it’s agriculture, geological exploration, smart cities, or energy & utilities, RMDT holds the potential to revolutionize how industries leverage IoT data, driving efficiencies, optimizing processes, and unlocking new opportunities.
