propojené otevřené systémy (OSI)
Open Systems Interconnection
reference model developed by ISO to enable different or similar systems to dialogue with one another
NOTE 1 This model constitutes a reference framework for describing data exchanges. Each layer performs a service at the request of the adjacent higher layer, and in turn, requests more basic services from the lower layers. It is described in 7 layers.
NOTE 2 Open systems interconnection (OSI) is an international effort to facilitate communications among computers of different manufacture and technology.

data packet
entity of data that can be sent between end-application systems in order to exchange information
NOTE A data packet relates to the Application Layer of the OSI stack and may be broken into several pieces by lower layer protocols.

end application message
message data structure that has been associated with a specific meaning and which, when properly sent in a data packet, an instance of the structure can convey information between systems
NOTE A data structure might, for example, be specified to include a list of speeds from detector stations. This one data structure could be used to specify the content of several messages (e.g. the list of current speeds being detected, the list of stored speeds that will trigger a congestion warning if current values fall below the indicated level, or a request for a list of locations where the current speed is less than the indicated speed). An instance of the message would then contain actual values.
