SeedLink is a real\-time data acquisition protocol and a client\-server software

SeedLink serves miniSEED data to clients in real times. It is a real\-time data

The SeedLink protocol is based on TCP. All
connections are initiated by the client. During handshaking phase the client can
subscribe to specific stations and streams using simple commands in ASCII coding.
When handshaking is completed, a stream of SeedLink \(dqpackets\(dq consisting of a

occurs. Data supplied by a plugin can be a form of miniSEED packets or just
raw integer samples with accompanying timing information. In the latter case,

SeedLink supports by default miniSEED records with a size of 512 bytes which
is hardcoded. For serving records with other sizes, e.g., 4096 bytes,
SeedLink must be recompiled with a modified variable \fIMSEED\-RECLEN\fP located
in \fBseedlink/apps/seedlink/iosystem.h\fP of the SeedLink repository.

SeedLink and ArcLink sources; this class is used by all SeisComP modules that
work with waveform data. On a lower level, SeedLink clients can be implemented
using the \fILibslink\fP [\fI\%16\fP] software library or its Java counterpart, JSeedLink. Libslink
supports Linux/UNIX, Windows and MacOS X platforms, and comes with an exhaustive
