With faster response times and better accessibility to maximize range and coverage in areas with poor network conditions, Quick UDP Internet Connection (QUIC) is poised to take CDNetworks’ live streaming capabilities to the next level.
SINGAPORE, March 9, 2023 /PRNewswire/ — CDNetworks, a leading APAC edge-as-a-service delivery network, announces support for QUIC and HTTP/3. This milestone represents a major leap forward in improving the company’s capabilities in terms of web application performance and improving network transmission efficiency. It will also benefit CDNetworks’ customer base and help companies deliver a superior digital experience to their end users.

QUIC is a network protocol developed by Google. With its high transmission efficiency and multiplexed transport capabilities, QUIC was adopted as a standard by the Internet Engineering Task Force (IETF) and became the underlying transport protocol of the next-generation Internet protocol HTTP/3. It is now widely regarded as a replacement for TCP.
A significant milestone worth mentioning
With more than 20 years of experience in Content Delivery Networks (CDN) and Media Delivery, CDNetworks is committed to breaking down network delivery barriers. From HTTP/1 to the latest version of HTTP/3, CDNetworks continues to develop cutting-edge technologies that improve network transmission and provide a rich and immersive user experience. As a testament to this commitment, CDNetworks’ platforms began implementing support for the QUIC protocol five years ago.
2018: CDNetworks implements support for the QUIC protocol.
2019: gQUIC is fully supported on all CDNetworks nodes.
2020: CDNetworks implements support for the latest version of gQUIC.
Now: CDNetworks implements support for all versions of iQUIC and gQUIC, including the QUIC IETF-v1 protocol standard.
Supported versions of QUIC-CDNetworks
gQUIC: Q39, Q43, Q46, Q50
iQUIC: H3-27, H3-29, IETF-v1(H3)
Doyle Deng, CDNetworks’ Head of Global Marketing and Product, addressed the importance of CDNetworks’ full platform support for QUIC, saying, “Prior to HTTP/3, TCP was the underlying transport protocol for HTTP. With the exponential growth of the Internet’s capacity and scalability, interactive scenarios are becoming more dynamic and complex. This places an enormous burden on real-time transmissions. For these reasons, it is becoming clear that the inherent performance limitations of traditional TCP can no longer meet current requirements.
The story goes on
“In this context, CDNetworks’ full platform support for QUIC demonstrates our commitment to enhance our service capabilities for last mile CDN delivery to consumers. On the basis of this underlying protocol (QUIC), CDNetworks can better support a wide range of companies and industries with significantly more powerful service functions. In addition, QUIC is well suited to provide end users in various application scenarios, such as live streaming and video-on-demand, in media streaming, online gaming, e-commerce, IoT, etc. to offer friendlier experiences to other Internet-based digital scenarios.” Doyle added.
Ready to embrace the era of QUIC
To address the new era of QUIC, CDNetworks has upgraded its platform’s frame processing capacity and optimized its performance to minimize resource consumption. Early results show that QUIC has had a significant impact on media delivery using CDNetworks’ new platform. “In QUIC stream pull scenarios with a bit rate of 1 Mbps and 20% packet loss conditions, QUIC is 20% smoother than TCP, with the first packet being delivered about 0.2 to 0.8 seconds faster than TCP. These results prove the transmission efficiency that QUIC offers TCP,” said Jaechoon Lee, Korea Head of Technical Solution Engineering.
QUIC can be easily adapted to a variety of use cases that require CDN acceleration, such as: B. Real-time applications, IoT, cloud computing, e-commerce and financial payments. CDNetworks expects QUIC to bring significant advances in media streaming scenarios, be it live streaming or video-on-demand. In particular, many of QUIC’s features are ideally suited to meet the needs of live streaming business scenarios. Below are some key features that QUIC offers for live streaming:
The main implications for live streaming scenarios
Video start time reduction
The handshake and connection times to establish a QUIC connection are much faster than TCP. Compared to traditional TCP, the QUIC transport layer uses UDP, which reduces the delay from a 1-RTT in a TCP three-way handshake. This reduced time shortens the first package delivery time as well as video start time for end users. This benefit is particularly attractive for latency-sensitive applications and a compelling reason for video application vendors to optimize their offerings with the QUIC protocol.
Improving live streaming for poor network environments
QUIC introduces the concept of multiplexing multiple streams onto one connection. By designing and implementing independent flow controls for each stream, QUIC solves the head-of-line blocking problem that affects the entire connection. QUIC also supports Forward Error Correction (FEC), which can reduce the number of retransmissions and improve transmission efficiency in areas with poor network range and reception.
These two features, together with the help of CDNetworks’ new platform, increase the bandwidth performance of typical QUIC stream pull scenarios by 41%, ultimately greatly improving the live streaming experience in poor network conditions.
To date, CDNetworks has provided QUIC services to several Tier 1 companies in media and entertainment, e-commerce, online gaming, IoT and other industries. CDNetworks has also helped media companies accelerate their streaming services of global sporting events using the QUIC protocol, ensuring high definition and a smooth viewing experience even with high concurrent viewership and traffic spikes. Going forward, CDNetworks will continue to spare no effort to provide even better digital experiences for global users by partnering with more organizations across multiple industries.
