Innovative Architectures for Ultra-Low-Latency WebRTC Streaming and Server-Side Recording in 2025: A Multi-Operator Perspective for Metro Manila

By 2025, real-time communication has become a fundamental necessity for high-density urban cen- ters around the world. In the Philippines—and in Metro Manila in particular—the rising demand for live streaming, interactive entertainment, remote work, and distance learning drives the evolution of com- munication technologies. This paper introduces an innovative WebRTC-based architecture engineered for ultra-low latency online streaming with robust server-side recording capabilities. We place special emphasis on the collaborative environment between major mobile network operators, including Globe and Smart, each managing a substantial network of cellular towers across a vast and densely populated region. Beyond detailing an in-depth evaluation of network performance metrics—bandwidth, Round-Trip Time (RTT), mobile tower densities, and user traffic patterns—this work demonstrates how advanced er- ror correction, adaptive transcoding, and multi-factor buffering strategies can radically reduce latency. To showcase practical relevance, we include extensive numerical simulations focused on real-world through- put gains, cost savings, and improved Quality of Service (QoS). Our findings highlight a path forward for hyper-dense cities seeking to accommodate the exponential growth in real-time, high-fidelity streaming while ensuring data integrity through server-side capture and archiving.
