Based on the architecture design, the entire system achieves its various functions steadily, preserving the coherence of the overall structure and benefiting the cooperative development and test.

The article expatiates the topological architecture of a VOD system based on cooperative cache, designs the static schedule and dynamic migration method in detail, and formalizes the design.

Secondly, taking the office automation system in Shenyang railway bureau Jinzhou engineering group for example, this thesis gives the architecture of cooperative OA system.
