MQTT Over QUIC White Paper: Next-Gen IoT Messaging Protocol

NewEnergyVehicles have ushered in the era of automotive intelligence, transforming cars from isolated transportation tools into smart carriers that can deeply integrate with the entire transportation system, providing users with a new digital experience.The era of intelligent connected vehicles also offers users more intelligent applications, such as assisted driving, autonomous driving, and intelligent traffic systems, all of which require strong networking and communication capabilities.

The rapid development of the intelligent connected vehicle industry necessitates reliable and efficient messaging transmission technology as support. Challenges such as protecting sensitive vehicle data, providing stronger security guarantees, and ensuring low-latency and reliable data transmission are faced by the industry.

As a global leading provider of IoT data infrastructure software, EMQ has been committed to promoting the development of the smart automotive industry through technological innovation. EMQ has innovatively introduced the next-generation underlying transmission protocol QUIC into MQTT. With advantages such as multi-stream multiplexing, low latency, and connection address migration, MQTT over QUIC can effectively address various data transmission challenges for intelligent vehicles in weak networks and frequent network switching scenarios, providing foundational technical capabilities for the development of the intelligent connected vehicle industry.

Based on years of deep cultivation and innovation in the intelligent connected vehicle field,EMQ has released the “MQTT over QUIC” white paper, which provides an in-depth analysis of the next-generation IoT messaging transmission standard protocol.

In recent years, EMQ has developed into a global leading provider of connected vehicle platforms, serving over 50 automotive companies, more than 100 vehicle brands, and over 10 million electric and conventional vehicles, while helping nearly 30 automotive companies and suppliers build connected vehicle data platforms. At the same time, EMQ actively promotes the standardization process of MQTT over QUIC as a member of the international standards organization OASIS, allowing more users in connected vehicles and mobile data collection scenarios to benefit from it.

The white paper aims to help more automotive companies understand and utilize MQTT over QUIC, seizing opportunities in key technology trends such as data closure, vehicle-cloud integration, and software-defined vehicles.

White Paper Highlights

What is MQTT over QUIC

MQTT over QUIC is a communication protocol that replaces the TCP transport layer in the traditional MQTT protocol with the QUIC protocol. QUIC is built on UDP and, as a new type of network communication protocol, is more suitable for communication under unstable network conditions compared to traditional TCP.

Advantages of MQTT over QUIC

MQTT over QUIC has a revolutionary impact on messaging transmission for intelligent connected vehicles, significantly improving message transmission performance for vehicles in motion. The design of QUIC can handle packet loss and network changes better than TCP, such as when vehicles switch between Wi-Fi and cellular networks. For MQTT applications running in environments with frequent network interruptions or on mobile devices, QUIC can provide a more stable connection. By combining MQTT with QUIC, MQTT over QUIC can further leverage the advantages of QUIC, including reduced latency, support for multiplexing on a single connection, connection migration, greater stability in weak network environments, and built-in security mechanisms.

EMQX: The First MQTT Broker Supporting MQTT over QUIC

Starting from version 5.0, EMQX supports MQTT over QUIC. EMQX is an enterprise-level MQTT IoT data access platform that provides more efficient and reliable MQTT message transmission, effectively building an ecosystem for intelligent connected vehicles and promoting rapid industry development.

NanoSDK: Client SDK Supporting MQTT over QUIC

NanoSDK is the first MQTT over QUIC software development kit developed in C language, fully compatible with EMQX 5.0. NanoSDK has the following main features: supports asynchronous I/O, maps MQTT connections to QUIC streams, achieves low-latency 0-RTT handshake, and utilizes multicore for parallel processing.
