CAPS is a data distribution and archiving server developed by gempa GmbH to transmit multi-sensor data from stations to the data center.
SeedLink is wide spread and widely loved. It is the de facto standard of real-time data transmission. But there is always room for improvement. You can think of CAPS as a more versatile SeedLink server.
Format-independent: CAPS archives anything (miniSEED, images from your office webcam, raw temperature data, continuous GPS data, tide gauge data, live video, whatever you send). It eats whatever the plug-in provides. Unlike slarchive, the CAPS archive is not limited to ONE format. You can store any format, even mixed formats. CAPS just needs to know the start and end time of a record, nothing else.
Sample-rate independent: CAPS can handle low and high sampled data in parallel (e.g., temperature data and continuous seismic or gps data)
Redundancy: CAPS can fetch data from multiple connections simultaneously (e.g., from a satellite link and Internet link). Data packets are then merged and duplicate records dropped.
Web-based: Built-in web interface for assessing data quality and data transmission fidelity.
On-the-fly Reconfiguration: No more down-time!!! You can reconfigure the CAPS server for new stations or change existing station parameters without stopping the acquisition server
Duplicate records are ignored.
Out-of-order packets are properly archived.
CAPS supports wildcard requests
Advantages of CAPS over SeedLink
A common acquisition protocol for all of your instrumentation: CAPS supports variable record size
Better protection against data loss: CAPS offers on-the-fly reconfiguration
Less overhead: A client packet consists of a minuscule 2 byte header followed by the data
Security: secure communication via SSL
CAPS offers web-based configuration
CAPS can handle backfilled data
CAPS does data acquisition AND archival

Similar to SeedLink, the connection between a data provider and CAPS is made through a plug-in.
Leave the command-line behind. Configuration, data and transmission quality control are made easy with the CAPS web interface.
