Design pattern oriented distributed system

A command pattern oriented distributed system is proposed. This pattern’s high-level framework is designed. In this framework, imported some components, such as command bus, command executor ect. According to the framework, the structure class diagram of the pattern is designed. Components’specific fuction is expatiated, and the command execution process is analyzed in the pattern. Based on the pattern, when developers design command classes, there is no need to consider how to sequence the command object and send it to server, and they don’t worry about receiving data from server and anti-serialize from the received data. Concluded that this pattern shielded the communication complexity of the distributed environment, so that developers can use command pattern in a network transparent manner in accordance with the original way.
