Abstract：It is a common practice for seismic networks around the world to transfer seismic monitoring data in real time to local data centers for online processing by using operator networks.Organizations such as IRIS and GFZ provide seismic data sharing servers based on the SeedLink protocol,which allows users not only to quickly access data to the local via the Internet,but also to perform for real-time seismic monitoring through system such as Seiscomp and Earthworm.Currently,the domestic seismic station network uses the NetSeis/IP protocol and Http protocol for data distribution,and uses the Jopens MSDP software for online processing.Due to the different data transmission protocols used at home and abroad,domestic data streams cannot be directly connected to systems such as Seiscomp and Earthworm.To solve this problem,this paper introduces the mainstream seismic data real-time transmission protocols at home and abroad,such as NetSeis/IP and SeedLink,describes the protocol instructions and data request methods in detail,and proposes a method to quickly build a lightweight SeedLink real-time data streaming server based on RingServer,which can realize the function of SeedLink server.On the one hand,it meets the data access needs of international seismic monitoring systems such as Seiscomp and Earthworm,and on the other hand,it provides a reference for online sharing of seismic data in China.
