Information Technology - Open Systems Interconnection - Transport Service Definition - Data Networks and Open System Communications Open Systems Interconnection - Service Definitions 33 pp
This Recommendation I International Standard defines in an abstract way the externally visible service provided by the
OS1 Transport Layer in terms of
a) the primitive actions and events of the service;
b)
c)
the parameter data associated with each primitive action and event;
the relationship between, and the valid sequences of, these actions and events.
The service defined in this Recommendation I International Standard is that which is provided by all OS1 Transport
Protocols (in conjunction with the Network Service) and which may be used by any OS1 Session Protocol.
This Recommendation I International Standard does not specify individual implementations or products, nor does it
constrain the implementation of entities and interfaces within a system. Conformance of equipment to this
Recommendation I International Standard is achieved by conformance to the protocols specified to fulfil the Transport
Service defined in this Recommendation i International Standard.
