Communications processor CK-Proxy is designed to ensure flexible exchange of telemetry data streams via internationally standardized protocols based on TCP/IP stack. It provides initial data processing and routing at the application layer of data exchange.


IT security gateway. It is located in the demilitarized zone. It supports data exchange modes with a minimum necessary number of connections to be established. The connections are initiated by a data exchange party located in the secure network. CK-Proxy ensures control of data exchange at the application layer by defining a list of allowed data exchange hosts with indication of IP-address, protocol, and a set of parameters allowed for reception and transmission for each host. It supports real-time monitoring of received and retransmitted data streams.

Protocol convertor. CK-Proxy ensures automatic conversion of received data packets into a different protocol format so that the data can be securely transferred to the recipient. Internally, CK-Proxy presents transmitted data in a standardized format so that all conversion combinations are possible provided that end-to-end communication parameters match.

Data stream multiplexer. It can be used with the automated system (a SCADA, supervisory control system, industrial control system, etc.) that do not support several simultaneous communication streams. CK-Proxy solves this problem by establishing a single connection to the automated system and the required number of connections to the other data exchange parties.

Configurator. CK-Proxy information model (configuration) is stored in XML-files that are created by a special editor. CK-Proxy supports simultaneous operation with the basic configuration model and a set of additional ones, which can be used to set up new connections without disrupting existing ones.
