CDNetworks Announces Full-platform Support for QUIC and HTTP/3, Making Live Streaming Smoother and More Accessible Than Ever

CDNetworks, an APAC-leading network to deliver edge as a service, announces support for QUIC and HTTP/3. This milestone signifies a huge leap toward enhancing the company’s capabilities in web application performance and improving the efficiency of network transmissions. It will also benefit CDNetworks’ customer base and help enterprises 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 Noting

With more than 20 years of content delivery network (CDN) and media delivery experience, CDNetworks is committed to overcoming network transmission barriers. From HTTP/1 to the latest version of HTTP/3, CDNetworks continues to develop cutting-edge technologies that improve network transmission and deliver 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.

Addressing the significance meaning of CDNetworks’ full-platform support for QUIC, Doyle Deng, Head of Global Marketing and Product of CDNetworks, said, “Before HTTP/3, TCP had been the underlying transmission protocol for HTTP. With the exponential growth of Internet capacity and scale, interactive scenarios are becoming increasingly dynamic and complex. This places a tremendous 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 demands.

“In this context, CDNetworks’ full-platform support for QUIC demonstrates our commitment to boost our service capabilities of the Last Mile CDN delivery to consumers. Relying on this underlying protocol (QUIC), CDNetworks can better support a wide range of companies and industries with significantly more powerful service capabilities. Moreover, QUIC is well suited to deliver more friendly experiences to end users of diverse application scenarios, such as  live streaming and video-on-demand in media streaming, online gaming, E-Commerce, IOT, and other Internet-based digital scenarios.” Doyle added.

Ready to Embrace the Era of QUIC

To embrace the new era of QUIC, CDNetworks upgraded its platform’s frame processing capacity and optimized its performance to minimize resource consumption. Initial results show that, with the help of CDNetworks’ new platform, QUIC has made a significant impact on media delivery. “In QUIC stream pull scenarios having a 1Mbps bitrate and suffering 20% packet loss conditions, QUIC is 20% smoother than TCP, with the first packet delivered roughly 0.2 to 0.8 seconds faster than TCP. These results prove the transmission efficiency that QUIC offers over TCP.” said Jaechoon Lee, Korea Head of Technical Solution Engineering.
