Atomic messaging in simple operations

Operation An operation is defined as the communication that takes place in order to make an operation on the bit repository. Examples are get and put of data.

Operations must be as simple as possible, based on . They will be based on simple message primitives and data transmission. A primitive is a single request message to the system and the following replies. The primitives are defined on basis of atomic weldefined messages. This serves to give simplicity, and to get as little overlap between different operations as possible.

Operations are seen as a sequences of messages which collectively correspond to a full operation. For example the Get operation consists of a sequence of 5 messages as illustrated below. Note that it is divided, since the GetTime part An example of the Get operation is given in the below figure.

Here the full communication will result in an operation. The message communication is divided into two parts, each representing a prinitive (identification of pillars and the actual get). Note that the primitive for identification of pillars can cover request to several pillars, while the primitive for the Get actual get part only concern concerns one pillar. Note that the actual data transmission is not included here although it will be part of a full operation.Image Removed
