How RC’s 4th-Gen Global Network Achieved a 40% Speed Boost

RC‘s fourth-generation global communication network, SD-CAN V4, delivers significant performance gains through targeted TCP and UDP acceleration. By allowing clients to connect via the nearest edge node, it reduces connection time by 30%. Furthermore, its full support for HTTP/3 boosts connection efficiency by 40% in regions with limited network infrastructure, ensuring lower latency and higher throughput.Since 2015, RC has systematically built and upgraded its global network, which now comprises eight data centers and thousands of communication nodes worldwide. The latest iteration, SD-CAN V4, provides a superior user experience powered by high-quality, low-latency data transmission.

Reducing Connection Time by 30%

The RC global network integrates multiple top-tier service providers to create a vast, uncongested infrastructure. To optimize access, it employs a combination of Smart DNS and Anycast IP, ensuring users worldwide connect to the most performant communication node available.The system also uses intelligent link detection. It supports multi-operator, multi-standard networks and aggregates multiple links to determine the optimal transmission path. This is achieved by combining server-side network selection strategies with client-side link quality probes. As a result, the upgraded network’s TCP and UDP acceleration enables clients to establish connections 30% faster by accessing nearby edge nodes.

Boosting Speed by 40% in Weak-Network Regions

Full support for HTTP/3 across all RC services is a key factor in improving performance. The protocol, built on QUIC, uses UDP for its transport layer, which enables a faster handshake. Specifically, clients can begin sending application data without waiting for the TLS handshake to complete, accelerating connection establishment.In areas with unstable networks, QUIC provides a more efficient packet loss retransmission strategy. It retransmits only the lost packets rather than the entire sequence, which is critical during network jitter. Additionally, QUIC supports seamless connection migration. When a device switches between 4G and Wi-Fi, the connection is maintained without interruption, creating a smooth, imperceptible transition for the user.

Achieving an SDK Crash Rate Below 0.005%

Performance stability is critical for a positive user experience. Beyond its 99.99% service reliability and robust anti-packet-loss capabilities, RC’s SDK crash rate is a key stability metric. In the global market, device fragmentation is a primary cause of application crashes, which can lead to business interruptions and a loss of user trust.According to a research report by Umeng+, the average crash rate for mobile applications is 0.29%. An iOS app exceeding 0.8% or an Android app exceeding 0.4% will typically see a significant decline in active users. In contrast, RC’s SDK, which is compatible with mainstream global handsets, maintains a crash rate below 0.005%—an exponential difference from the industry standard.To further enhance performance, RC has optimized the compression and transmission of high-definition images and short videos.

• Images: Using the WebP algorithm, image compression efficiency has improved by nearly 60%, resulting in smaller file sizes and higher clarity.
• Videos: A segmented compression and upload technique reduces file sizes by 63%, improving resource utilization and enabling near-instant playback upon receipt.
• Push Notifications: Through optimizations like delayed push compensation, notification delivery rates have increased by 20%, and delivery speed has doubled.

Conclusion

Since 2015, RC has relentlessly optimized its global communication network. Its fourth-generation platform reduces connection time by 30% through intelligent routing via Smart DNS and Anycast IP. In weak-network regions, it leverages HTTP/3 to boost connection efficiency by 40%. With a service reliability of 99.97% and an SDK crash rate below 0.005%, RC’s performance far surpasses industry benchmarks, providing a high-quality, low-latency, and exceptionally stable foundation for global developers and enterprises.
