Layer 4 proxy is an acceleration service offered by Edge Security Acceleration (ESA) that improves your application performance and security protection. It provides global acceleration and Anti-DDoS protection for applications that use TCP/UDP Layer 4 protocols, which are common in scenarios such as games and instant messaging. Layer 4 proxy supports all ports from 1 to 65535 and includes features such as certificate-free deployment.
Feature overview
Feature | Overview |
If your application, such as a real-time multiplayer game, interactive video stream, or IoT service, relies on layer-4 (TCP/UDP) protocols, you may experience high latency and network instability over the public internet, which degrades the user experience. Edge Security Acceleration (ESA) mitigates these issues by routing user traffic to the nearest global Point of Presence (POP). From the POP, traffic is forwarded to your origin server over Alibaba Cloud's optimized network, which reduces latency and packet loss. This ensures a smooth, responsive, and secure experience for your end-users, regardless of their location. | |
Edge Security Acceleration (ESA) analyzes Layer 4 proxy log data to provide multi-dimensional analysis and visualizations for your site. This analysis includes time-based trend curves for metrics such as traffic, connections, and connection duration, along with data on country/region distribution and Top N rankings. |
