Why Multicast Matters

In a world filled with connected devices, the way we move data hasn’t evolved fast enough. Many networks still rely on unicast - sending the same data one device at a time. It works, but it’s painfully inefficient when you need to reach thousands or even millions of receivers.

Multicast changes that. Instead of sending identical data repeatedly, multicast enables a single transmission to reach all receivers simultaneously. It’s the difference between having one-on-one conversations and speaking to an entire audience at once.

The Challenge of Reliable Multicast

So, why isn’t multicast everywhere already? There are two main reasons: network support and reliability.

First, the Internet at large does not support IPv4 or IPv6 multicast. Work to address this has been ongoing for years at the IETF — see the excellent efforts in the MBONED working group. Despite this limitation, many private environments such as enterprise LANs, WiFi, and satellite networks do support multicast, where it provides a powerful way to increase efficiency and reduce bandwidth usage.

The second challenge is reliability. Traditional multicast protocols can’t guarantee that every receiver gets every packet, especially when networks are unstable — like WiFi, satellite, or mobile connections. A few lost packets can cause applications to fail, videos to freeze, or firmware updates to break.
This has held multicast back for years. Without reliability, its efficiency doesn’t matter.

NanoPing - Reliable Multicast for the Real World

NanoPing makes multicast reliable. It combines Forward Error Correction (FEC) with Random Linear Network Coding ( RLNC) to ensure that every receiver gets the full dataset - even if some packets are lost along the way. Instead of retransmitting missing data, NanoPing’s technology lets receivers rebuild what’s missing using encoded information already in the stream.

The result is a network that scales effortlessly. Whether you have 10 devices or 10,000, the delivery time stays nearly constant.

Built for Complex Environments

NanoPing is designed for real-world scenarios where reliability meets scale.

IoT and Smart Infrastructure

Smart cities and industrial networks depend on thousands of devices that must stay updated with minimal maintenance. NanoPing enables Over-The-Air (OTA) updates to all devices at once, without overloading the network.

Connected Vehicles

Cars, trucks, and autonomous systems require frequent security and software updates. NanoPing allows manufacturers and cities to update fleets wirelessly - safely and efficiently - without service downtime.

Satellite and Remote Networks

From ships and offshore installations to agriculture in remote regions, NanoPing provides a dependable way to send data via satellite. Even when connectivity is sporadic, updates can continue in the background and resume when the signal returns.

Aviation and Content Distribution

Updating hundreds of in-flight entertainment systems or field-deployed devices becomes straightforward with NanoPing’s multicast. Massive content libraries can be distributed wirelessly without straining bandwidth or increasing operational costs.

The Efficiency Multiplier

With unicast, the time to deliver data grows linearly with every added receiver. With multicast powered by NanoPing, the delivery time remains virtually the same - no matter how many devices are connected. This is what makes NanoPing’s approach truly scalable.

Multicast is not just a technical upgrade. It’s a fundamental shift in how we think about network efficiency and reliability.
