Abstract:In earthquake early warning scenarios,the timely dissemination of warning information to the large population in the epicentral region is crucial for mitigating disaster impacts. However,current systems face limitations in pushing hundreds of thousands of messages per second. To address this challenge,we have developed a high-concurrency,hierarchical cascade broadcast,and region-specific push technology capable of delivering tens of millions of early warning messages per second. To validate this technology,we constructed a multi-level cascade release platform comprising 95 high-performance servers,with 45 of these servers simulating 10 million users for experimental purposes. We implemented CPU core binding and Zookeeper cluster management techniques on the Central Management (CM) side to enhance both the individual server push performance and the stability of linear scalability within the cluster. Excluding actual network latency,the system demonstrated the ability to push tens of millions of early warning messages per second. The overall push delay for 10 million messages was maintained within 500 milliseconds,thereby meeting the performance requirement of pushing 10 million messages per second. Additionally,the system's push capability was further validated through practical environmental testing,confirming its region-specific push functionality.
