High concurrency
LCIC is deployed on distributed edge nodes to allow global teachers and students to enjoy faster access. It features multi-path transfer over the entire network, smart dynamic routing acceleration, and imperceptible scheduling and switchover to guarantee high availability. Based on a highly elastic network architecture, it can sustain loads over 10 times greater than those during normal off-peak hours. A channel with millions of users and tens of millions of concurrent requests can also be well sustained.
Low latency
LCIC offers a highly connected, reliable, and secure network across the globe. Leveraging our proprietary multi-addressing algorithms, it has the ability to stream users' audio/video data to optimal nodes across the entire network. With abundant high-bandwidth resources and globally-distributed edge servers, it can ensure an average end-to-end latency of below 300 ms between countries/regions. Based on over 2,000 global network nodes, network optimization is implemented specifically for countries/regions of teachers in Southeast Asia, Northeast Asia, Middle East, North America, and Africa, delivering a high-quality transfer rate of 99% or higher over the global network.
Low lag
LCIC reduces the lag rate using smart QoS control and optimized encoding. It guarantees high-quality, smooth, and stable audio/video communication even under poor network conditions (packet loss of over 80% and network jitter of over 1,000 ms).
High quality
LCIC supports 720p and 1080p video and allows video streaming even under a packet loss rate of 70%. It supports 48 kHz audio and uses the industry-leading 3A technologies of Tencent Ethereal Audio Lab to remove echo and howling. End-to-end 128 Kbps bitrate and dual channels ensure a clear and immersive audio interaction experience.
