Description

The scenario is: Get Part of File

This scenario is an extension of the first test scenario. Here the client gets part of a file. It could for example be the first couple of minutes of a longer video file. In this scenario it is an offsett of 0 and length 4 Mb.

The scenario should start with an IdentifyPillarsForGet conversation (Step1 in scenario 1) (again not required, but best behaviour and a better starting point for the client as it then knows the currently best place to ask for the file). Only the Get conversation between client and Pillar2 (assumed to be fast) is described.

• (2a) specific GetRequest from client to specific pillar
• (2b) answer in form of data transmission

Illustrations to come. The following is concrete values in the general message format and in XML.
