GFZ based on software library provided by RefTek, Inc. GFZ based on lib330 maintained by ISTI, Inc. Transfers miniSEED files from a directoryĬhad Trabant (IRIS) based on sample code from Nanometrics, Inc. Supports Linux/UNIX, Windows and MacOS X platforms, and comes with an exhaustiveĭocumentation in form of UNIX manual pages.Įarthworm export server (TCP/IP), Chad Trabant (IRIS) Using the Libslink software library or its Java counterpart, JSeedLink. On a lower level, SeedLink clients can be implemented SeedLink and ArcLink sources this class is used by all SeisComP modules that In SeisComP the class RecordStream is implemented that supports both Antelope, Earthworm and NAQS can also import data from The included C language plugin interface is described in More plugins (Kinemetrics K2, Lennartz MARS-88, Lennartz PCMĥ800, etc.) have been implemented by various users, but are not (yet) included The table below lists digitizers and data acquisition systems that are supported by The SeedLink server uses an inegrated “Stream Processor” to create the desiredĭata streams and assemble miniSEED packets. Raw integer samples with accompanying timing information. Data supplied by a plugin can be a form of miniSEED packets or just Server, e.g., a plugin is automatically restarted if it crashes or a timeout Server can be anything which is supported by a SeedLink plugin - a small program The SeedLink implementation used in SeisComP. In the following we use “SeedLink” to denote On the other hand IRIS DMC implements some extensions whichĪre not supported by other servers. Implementations are generally compatible, but not all of them support the full Manufacturers have implemented SeedLink in their digitizer firmware. Another well-known implementation is deployed in IRIS DMC and some In SeisComP is the oldest and most widely used, however, other implementationsĮxist. The packets of each individual stationĪre always transferred in timely (FIFO) order. When handshaking is completed, a stream of SeedLink “packets” consisting of aĨ-byte SeedLink header (containing the sequence number) followed by a 512-byte Subscribe to specific stations and streams using simple commands in ASCII coding. AllĬonnections are initiated by the client. SeedLink is a real-time data acquisition protocol and a client-server software
