Telecommunications and information exchange between systems — Recursive inter-network architecture — Part 3: Common distributed application protocol

This document provides the common distributed application protocol (CDAP) specification. CDAP enables distributed applications to deal with communications at an object level, rather than forcing applications to explicitly deal with serialization and input/output operations. CDAP provides the application protocol component of a distributed application facility (DAF). CDAP provides a straightforward and unifying approach to sharing data over a network without having to create specialized protocols. This document provides: — an overview of CDAP; — the specification of CDAP; — a description of policies, in the specific sense introduced in the text; — notes on the context of CDAP.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
